LoneWolfUSMC posted a video on YouTube explaining some of the benefits of a rear mono-pod over a bag.
The S&W M&P15 has become very popular due to its low cost and availability. My personal experience with owning one was that my M&P15R had an incorrectly cut upper that would not hold the ejection port door closed, the stock was not installed correctly and was crooked, and the fire control group was defective and would double. S&W replaced the lower on my rifle, and I did not bother to have them work on the upper.
Often at the range I have seen people have minor issues with M&P15s. The new low cost model (around $700) came with a near useless rear sight. This cheap copy of the detachable carry handle often would not index correctly. Last Sunday, I saw this issue. This new, out of the box, M&P15 came with a broken bolt catch. While I have no doubt that S&W will fix this, I have been less then impressed by S&W quality control on their rifles.
Part two of my review of the Colt LE901 will be the results of my shooting of the gun, its accuracy, performance and handling. I shot the rifle with all of the more popular match ammo and with handloads. I also took the gun out past what the company reasonably expected it to be fired at. I expected the gun to perform well with its accuracy since it is in essence a larger 6940. The 6940 with its free floated barrel and unique barrel nut has been a very impressive performer. The results still surprised me a little bit and shocked me with what it did at 1000 yards and beyond.
The 1st set up groups were shot using 168 grain federal match, M118LR, Black Hills 175 match. This was the first shooting from the gun after I got it. I placed a Leupold 18x target scope in larue mounts on the upper and got a rough zero then proceeded to shoot for groups. The groups were shot at 100 yards on a calm day using bipods and a small rear sandbag rest. I considered this to be outstanding accuracy from a chrome-lined military 16 inch barrel. The 901 is pretty much a battle rifle, and to expect this accuracy from a battle rifle is not always reasonable. Some battle rifles will give good performance but 2-3 MOA is usually considered fine for such weapons.
Above picture represents the rifle setup used for all accuracy testing.
The next set of testing of accuracy was long range. I started out shooting the rifle with the common Federal Gold Medal 168 grain loading. I used steel gongs at 600 yards the size of a man’s chest and a steel shaped groundhog. With only 16 inches of barrel, velocity did fall off as expected causing me to need more adjustment on the optics compared to my normal 26-inch bolt-action. Some people seem to think shorter barrel means less accuracy but this is simply not true. You lose velocity but not accuracy. A quality barrel will always shoot and the shorter it gets, the stiffer it becomes and usually will gain a slight edge in accuracy with the shorter stiffness.
Posing beside the target for scale,the T-1 was not used for the 600 yards shot and was installed afterwards.
The groundhog target can be seen over the authors left shoulder. Hits were made easily once the scope was adjusted. Military ball ammo could be used to make repeated hits out to 600 yards though not with the reliability of the match ammo.
The next step tried with the 901 was 1000 yards. For this test I used the popular 168 grain load and my own handlaods of Berger 175 grain Berger VLD bullets with Varget. I set up the target at 1000 yards and got to work. Because of no cant on the base or the upper I ran out of elevation on the optic. The optic was the Leupold 18x with a 1 inch tube. It is a target varmint scope and not suited to true long range work unless a canter base is used. Not being able to zero and hold point of aim/point of impact, I had to hold off. This made wind correction difficult. It did not take long to become frustrated trying to determine hits on target with using hold off. So I settled on using the steel gong I used to get the rough zero at the distance by putting it a foot behind the paper target. In doing this, I was able to hear the steel ring when I was enough on paper to record a hit. With the wind blowing 8-12 MPH on the day trying to watch the dust from misses was not going to work. The gong behind the target worked well.
Because of the distance and the length of the barrel, the 168 grain load was a no go. I tried but the rounds just could not make it. The 168 has trouble staying super sonic even in a 26 inch barrel at 1000 yards, and in a 16 inch barrel, it was pointless though I did try. A lot of people seem to think the accurate 168 load is the standard but it simply is not. The 175 grain loadings for long range are better in every way and have been in use for sniping for years now in its M118LR form.
Once I fired at 1000 yards and saw the 901s performance I tried my luck at 1200 yards. So I moved back another 200 yards and tried again. The group at 1,200 may not seem like much, but in a carbine not meant for this work, it is impressive. The groups are marked in the picture circled in different color to indicate which groups was shot at the different distances. Blue for 1000 yards and green for 1,200. The 1000 yard groups does not seem as impressive as it really is at first glance. Wind was catching me and taking the shots off to the left. Since I could not see the hits I used the same hold through the whole string of shots, but if you move the holes over to the right, you will see the most of them would have fallen in the bad guys chest and would have been lethal. The position of the group is my fault , not the fault of the rifle. The 1,200 yard group is better than at first seems as well. It may not be sniping precision but it is enough to make hits at the range or at least provide effective covering fire. It is surely good enough to disable a vehicle form the distance, or any other machine that needs stopped, or even to direct fire for a machine gun team? Who knows, the possibilities are what you make them.
After this testing I shot the rifle in the usual fashion using tactical drills and IDPA target, Q targets, clay pigeons and steel gongs. Most of this general purpose was done with ball ammo and some match thrown in. After over 1,200 rounds at that point I had not cleaned or lubed the 901. It worked as flawless as it did when I took it out of the box. At times I heated the gun up so much I needed gloves to continue to fire it and even the mount that held the T-1 to the upper was too hot to the touch for bare skin. At no point did the gun have a problem or feel sluggish. After totaling up those rounds fired with no cleaning I decided to test its accuracy again. I would test it dirty and if it did not do well I would clean the barrel and try again, showing the effect of fowling if it was drastic.
I used the same optics and mounts as before but for the next test I used a dedicated Benchrest competition style front rest that weighs about 35 pounds, with a sandbag on the rest and a rear bag. To get all I could from the gun I concentrated and used all my effort to shot the best groups I could. Most groups took longer then 10 minutes for 5 rounds. It is hard work to shoot small groups and total effort when using a milspec trigger and a semi auto. Shooting a semi auto is a different animal then shooting small groups off a bench with a dedicated bolt gun with a target stock and has different needs you have to be aware of.
This set of targets were shot first while the gun was dirty with over 1200 rounds of fouling. I decided there was no need to clean after getting these result. They are slightly better then the original test for accuracy so I felt cleaning would not help or hurt much. If anything the gun shot slightly better, perhaps do to some break in. After years of experience I have come to the conclusion that barrel break-in is a waste of time. I can not think of any good reason why the gun did better and I surely never used the conventional “wisdom” of 1 shot, clean, repeat etc etc.
The 10 rounds group of Black Hills 175 grain was shot last and is very impressive to me. I have seen few factory bolt guns that would shoot this well and I do not recall ever seeing a factory M1A or M14 that would do as well.
Here is a picture of all the groups side by side.
The gun now has close to 2000 rounds though it still with no cleaning. I am able to make head shots out to 300 yards with it and stay within the CNS or “A” zone of the badguy targets if the wind is not too bad and I do my part. If not, head shots are still easy. I have lubed the BCG since it was bone dry, and have created a nice black slurry that has not done anything negative except ruin my t-shirts.
In Part 3 I will talk about shooting the gun in a more “run and gun”manner, how it feels, what the recoil is like and how I set it up for comfort and shooting it wearing gear.
The USMC decided to replace the Winchester model 70/Unertl combination in late 1965 due to the recent changes to the M70 from the pre 64 version and for a lighter rifle scope combo that made quick first round hits easier. The MTU was tasked with coming up with a rifle suitable for the Corps needs for the new sniper program. The MTU conducted tests comparing COTS rifles and scopes currently on the market in December 1965 and January 1966. The testing concluded that the Remington 700- 40x target rifle and the Redfield accu-range 3x-9x rifle scope the best choice for standard sniping issue at the time.
The urgency for the testing resulted in only COTS rifles and optics to be tested by the MTU. Due to the pressure for a fast decision, the MTU worked with the following self imposed assumptions.
The cartridge used would be the the 7.62 NATO.
Most shots would be made at 600 yards or closer.
The scope would be adjustable to 1000 yards
The rifle/scope should be capable of 2 MOA
The combo should be simple and robust and easily trainable.
After the MTU finished the report they recommended that the rifle used be the remington m700-40x. The stock have a dull oil finish. Swivels be military type non removable. The rifle finish to be dull non=glare. The rifle barrel should be 1/10 inch twist, free floating and the action be clip slotted. The USMC wanted a 308 caliber rifle with a medium heavy barrel in a sporter stock and remington company made every effort to give them exactly that,
On April 7th 1966 the remington M700 with redfield scope was adopted for sniping use in south east asia. The USMC stated that nothing about the rifle was unique, just the right combination of parts.
The rifle was planned to be in service by June of 1966. the rifle had a expected service life of 10 years and was to manufactured entirely by remington which would furnish all support equipment for the rifle including optics, carry case and ammo.
The amount of M40 rifles produced by remington for the USMC by year is as follows:
1971/ 1 rifle
By 1973 according to official documents, there was only 425 total density of M40 rifles still in service by the USMC.
The M40 was issued to be used with the Lake City M118 special ball match ammo. the USMC was the fist to use specialized match ammo dedicated for sniper use and the US Army followed.
The rifle was well liked upon first issue by personnel in the sniping and marksmanship community. Reports of the rifle easily shooting 2 MOA from bags with match ammo were normal. Some problems with the redfield scope had already started to surface however, with complaints that it was not easy to adjust for range, would loose focus if turned to 9x and the range finder in the scope would melt if the sun was directly on the objective. The rifle can be uncomfortable during recoil with its light weight and metal butt plate. Marine sniper school students often used rubber shower shoes under their Tshirts during practice to damped the recoil and cut down on the pain.
The rifle was sent to Vietnam and was issued to scout snipers who loved it early on. A number of famous snipers used the M40 to great affect. Chuck Mawhinney made his record 109 kills using the M40 for most of his time and Carlos Hathcock using a M40 for his 2nd tour.
After being issued and seeing service, the problems with the rifle/scope started to show. The rifle, nor the optic were meant for the tropical climate of asia or combat use but did preform well over all. The problems normal for the rifle was the stock warping and putting pressure on the barrel, rust, the scope fogging and the ranging scale melting in the sun. To help the situation Marine RTE armorers were assigned to take care of the rifles and optics while the sniper were responsible for standard PM. The rifle were soon found that they needed to be glass bedded often. The barrel channel had to be constantly check and rasped to keep the barrel free floated and the stock water proofed. The trigger needed to be checked along with the action. Lube was needed often as it was with everything in asia and special “hot lockers” were made by the RTE personnel to dry out the scopes over night after operations to make sure they did not fog up when needed.
RTE personnel soon traveled to keep a check on the rifles and help keep them working. It was found not all losses were combat related. Sometimes a rifle could be out of action just from a ride in a truck. Most being out of action due to scope failure. Most scopes would be out of focus over 8x so the snipers learned to focus only as high as 7x or 8x. Another problem was the optics would sometimes freeze in place if left at one power setting too long. Eventually the snipers learned to watch the optics and glass bedding was authorized for the M40. The stock would warp so badly with the un bedded actions that armorers would take the gun apart and find the action screws tightened so tight that they would not be making contact to the stock from warping and shrinking in the heat. Once glass bedding was OK to do the barrel was floated with 1/8 inch space between barrel and stock and waterproofed. Much of the problems were controlled with careful PM and use.
After most of the problems were understood the general attitude for the M40 was that accuracy was fine and the gun worked as meant and did well. Most liked it fine and felt the gun was almost the equal of the M70 used by earlier Marines. Few had the time and experience to have used both for sniping during the course of the war but Carlos Hathcock who did have the chance thought the M70 better at the time but liked one as well as the other.
After the war the M40 was retained as sniper standard for the USMC and upgrades were made to the original rifle. Improvements included at SS match barrel, a Mcmillian fiberglass stock with a woodland camo patter and a 10x Unertl scope to name a few. The rifle was renamed the M40a1 and has remained in service now in the M40A5 form.
The gun used in the pictures in the remington 2006 scout sniper association re issue. A limited number were made to the same specs as the original. The gun came with a letter ot authenticity from Iron Brigade Armory who helped make sure it was correct. IBA has long been THE source for USMC sniper history. The rifle came correct with the oil finished walnut stock, metal butt plate, barrel parkerized with matching receiver finish. The action is the remington 40x action that has been clipped slotted for stripper clips and has the left side drilled and tapped for rear peep sights. The serial number begins with the SSA ( scout sniper association ) prefix and has the correct U.S. stamped above it.
Standing in for the original redfield accur-range USMC contract scope is a modern redfeild painted green to resemble the original which is very hard to find. The original M40 came with the original redfield JR bases and rings along with the scope. Badger arms made a limited run of these bases and rings for the M40 limited re issue and Leupold has a small run of green finished 3x-9x scopes for the same rifle. Neither was completely correct in make or type but was close enough for most wanting a clone or the original and a considerable amount cheaper.
Above is a picture of the original SHOT SHOW remington flyer for the M40 signed by 3 famous Vietnam USMC snipers and members of the SSA, one being the president at the time, for the author. To the left is the gold scout sniper challenge coin that came with the rifle depicting a USMC sniper in the setting position with a winchester M70/Unertl.
The remington M40 re issue is a nice rifle and a piece of history. They made a very small run but if you are interested in sniping history or the history of the M40 in USMC service it is worth your time to track one down. In 2006 the rifle was around 1100 dollars but would be higher today as everything is. But its a fast way to get started on a sniper rifle collection.
LooseRounds has some pictures of a few new guns that are not easy to find.
First the Colt 6920 with FDE anodizing.
The carbine comes with Magpul MOE furniture in FDE, mags and the MBUS. The finish color looks better not under high-powered digital camera flash.
Next a few shots of the Daniel Defense new rail and Front Sight Base and the DD “MK18” Clone.
No bayonet lug on the DD. I am sure this will rankle some nerves, but we need to move on from worrying about a useless feature for a 16 inch barrel. Worry about marksmanship, not bayonet lugs and you will live longer.
The new DD flash hider. Not sure what it does different then a standard A2 hider.
The new rail profile.
The DD MK18 clone.
Also got a look at the colt competition rifle.
The colt competition has a FF smooth tubular rail with cooling vents, and a different barrel fluting and gas block.
The colt rifle pictured came with a surefire brake.
