Scalarworks LDM/micro Mount, Initial Thoughts

The generous guys at Scalarworks ( were kind enough to send me one of their 1/3 Low Drag Mounts (LDM)  for Aimpoint Micro’s to review. I have been following the LDM development for a while and was very interested in the mount. It’s lightweight, skeleton construction seamed perfect for a lightweight fast carbine.  I wanted to get my quick, initial thoughts out and post some pictures.

I have to say, after opening the packaging and getting my hands on the LDM, I was extremely happy.  This thing is light. It felt like it weighed less than the small cardboard box it came in. I immediately mounted it up on a Colt AR6720 and was very pleased. I really like the scalloped thumbwheel construction,  used to mount the LDM. Also, the LDM just looks badass.

Construction and mounting the LDM  is rock solid, lightweight and low profile.  I have several of the popular / well built / reliable micro mounts, and on initial inspection of the Scalarworks LDM, I can say it does not disappoint.

The Aimpoint Micro seems to be floating in the air over the receiver with this mount. I am eagerly waiting getting on the range with the LDM. Some very minor modifications have been made to the LDM mounts, due to user feedback and I think the LDM is looking like a rock solid piece of gear.  As soon as I get some rounds down range, I will report back with an in-depth review.

Infantry Weapons And Usage In Korea( Lessons To Be Learned )



A long title to be sure, but I don’t have any better idea on how to title this piece. Originally intended to be a post of the length I typically write, it turned out to be longer. Since there is too much useful information to be mined form this long forgotten DOD study, this post will be at least two parts and maybe more. It is interesting enough to justify more than one post.

I have been reading a US Army study on infantry weapons and us in combat during the Korean war. The study gathered its data in the manner used by S.L.A. Marshall for the most part as well as other methods. While it presented info and opinions of the users long known among small arms students, it also has some surprising information that does not always jibe with long held beliefs of the family of weapons in early years after WW2.

The best part of the study is the immediate reaction of the users as soon after an operation as the interviewers could get to them.

“After a given company or command had been interviewed concerning a specific action, and its detail had be encomposed, all concerned were then asked to evaluate their firepower, as to what addi-tional weapons would help or what weapons were either superfluous or for any reason not worth their weight under the conditions of the fighting. Officers and men took to this actively and in utter honesty of spirit.”

“But their general reaction to the weapons family was almost universally to the point that what they have is good and adequate to the tactical need.The vehemence with which they expressed this view was the more surprising because,in the greater number of the actions, they had undergone local defeat.”

I think most people familiar with the weapons of the time hold the view that the average Korean “GI Joe” was well served by the weapons provided for them.  That is, the M1 being loved, the M1 Carbine being hated  and so on. This has gone on to be some thing “everyone knows.”   When facts and opinion gets to the point of “everyone knows” I have always felt the so called fact is ready for a hard look. And in that  personal ethic, I wanted to take a look at something everyone knows. How the Infantrymen felt about their weapons during the bleak years of the Korea War 50-51 as captured by a US Army study and infantry weapons and the men who used them.

The M1 Carbine has a very mixed reputation, some love it and some hate it.  I have always found that its bad rap seems to have started in earnest during the Korean war.  One unit, the 38th regiment seemed to love the little carbine, but the study reports the unit to be very unique.

In all other units, bad experience in battle had made troops shy of this weapon, so that in the main those who continued to carry it of their own choice were either the lazy, the new arrivals, the few who had “pet” carbines that had worked perfectly all along, or the individuals whose tasks did not permit them physically to carry the M1. In all save one company after-action critique, malfunctioning of the carbine was prominent in the detail of weapons performance during engagement.”

Having nothing else to go on, it seems you can make a few assumptions with this statement. If one was willing to make excuses to try to explain away the dislike for the M1 Carbine.   Being lazy, but still carrying it, I could imagine the same time of guy would not ever bother to clean it unless was made to. New arrivals who did not have the training on the weapon and the ability to keep it running.  While those with so called “pet” carbines liked it.  Perhaps it was a pet carbine and worked because they gave it proper care? Certainly a devils advocate has some wiggle room to go on. But the next paragraph shoots that out of the water with crack units explaining that the weapon was something you could not count on.


“It is impossible to give exact percentages because of the scrambled nature of the fighting; some men would report having two or three carbines fail within one action.Others could remember picking up a weapon in a moment of emergency, only to have it misfire, but could not say for certain that it was a carbine.However, in each critique, as carbine failures were reported incidental to the fighting, the men were asked for a showing of hands on this question: “How many of you who have used carbines at any time in Korea have experienced a misfire during some part of the fighting?” The lowest showing in any company was 30 percent. In some companies of the 27th and 35th Regiments -two extremely efficient and battle-wise organizations -the figures rose to 80 and 85 percent.This reaction should be weighed against the background of troops’ satisfaction with their other fighting tools. Even if the percentages are exaggerated -and that possibility is admitted -the fact that they feel that way about it implies that they have lost confidence in the weapon. Pending an obvious correction, that of itself makes the weapon a liability in terms of both morale and fire power.”

Going on the report mentions the use of small arms used against the enemy when artillery could no longer be used.  The ranges the small arms of the time were used the with the most effect described.

“The beating-down of a closely engaged enemy must be done mainly by weapons within the infantry battalion. Recognition of the enemy, as he comes forward, is most likely to occur at some distance between 15 and 150yards from the infantry MLR -too close and too late for practical and successful artillery intervention.”

These distances of 15 to 150 yards are one of the many reasons the Army started with the later marksmanship training methods. In these after action reports, one can see the start of the realization that the days of  a battle rifle knocking down commies and nazis at 800 yards with large full power 30 caliber bullets, were  about over.  Indeed, this is cold hard evidence the M14 was obsolete the day the first STG44 was handed to the first German rifleman.


“The average effective infantry fire with weapons lighter than the machine gun was consistently less than 200 yards. In no instance was it established, in the operations brought under survey, that any significant move by enemy forces had been stopped and turned by rifle and carbine fire alone at ranges in excess of that figure.This, perforce, limits the significance of the evaluation. It rarely happens in the Korean fighting or elsewhere that a tactical situation of large order arises which tests the effectiveness of the rifle alone as a stopping and killing agent. By the nature of engagement, the infantry contest between opposing groups of riflemen is pretty much confined to strong patrol actions, fire exchanges between small groups within a larger skirmish, or last-ditch stands by companies which have emptied the ammunition from heavier weapons in the earlier stages of the fight. In the latter situation, the contending sides almost invariably close to within less than 150 yards before the climax is reached in which the position is held or lost according to rifle effectiveness.”

Here again we see the common use of the rifle. The power and range of the M1 Garand made little difference in the vastly common engagement distances. The M14 would certainly not have changed this outcome and the ranges of Europe certainly could not justify the need for a longer range battle rifle when shots in Korea would have been just as far or further.  With the NK and Chinese forces using PPSH and other type of weapons, the full power battle rifles certainly did not give the fighters any edge over them.

Even the famous rifle prowess of the USMC had little effect on enemy soldiers at distance.

“The Marines who were under siege at Koto-ri through the early days of December told of their effort to pick off Chinese riflemen who in broad daylight would stroll to within 300-350 yards of the armed camp or walk in the open to a stream bed to draw water. They found the targets far more elusive than they had expected.”

Of course none of this is to say the rifle was inaccurate or the men unskilled.  In fact, the report even made certain to point this out.

“What is said here is meant to reflect in no degree whatever on the accuracy of the standard rifle; the men who use it in battle swear by it. Junior officers frequently said that they had seen it do decisive work in excess of 250 yards range.”

I think it does indicate that while it is important to have the skill to hit a man at the potential of the weapon, it does point out that the idea of full power “battle rifle” is just not needed and the vast majority of the time, would not be used by the average user.

“Rifle practice at the longer ranges is still desirable. But the rifleman needs about five times the amount of practice now given him with live ammunition if the weapon’s potential is to be fully exploited in combat.”

I could not agree more with this last statement, regardless of rifle or service round used, everyone should constantly strive to keep their long range skill equal to their CQB to mid range skill.   It has always been out opinion that a modern rifleman, is not just a a CGB shooter or the guy who lays prone with his precision bolt gun, but the whole package.  Like any skill., often it takes a long time to master.  A Japanese friend once told me that he saw shooting, as the USA’s  Martial Art., I had often thought this, but is statement was on an even deeper level.  I think it certainly deserves life long dedication.


Part 2 of this post will be up next week, with more info on the individual weapons of the Korean war as well as their effect and the opinions of the users along with further comments.





Shotgun vs. Pistol for home defense

Clint Smith of Thunder Ranch posted up a video comparing the overall length of a shouldered shotgun to a pistol held at arms length.

I like Clint Smith’s teachings and while this is a valid point, I still prefer the pistol. Why?
The pistol can be fired from compressed shooting positions, something not so much possible with a shotgun.
I can better employ a pistol one handed then I could a shotgun. Try calling the police while holding a shotgun, opening doors, or carrying an infant.

Longarms have many advantages over handguns but they have their own downsides. You really need to pick the one that best fit your needs.

More Thoughts And Follow Ups From Some Others On The M14

Last weeks post on the M14 and its variety of shortcomings certainly stirred up the ire of its faithful followers. Link to offending article below.

Indeed we had to sleep under the bed with a gun in our hand  in fear of The Old M14 Boys Club coming to take us away.  Surprising to the guns fans, many spoke up with their actual real world experience with the piece confirming the point of the article.

Most recent is a sand test video from In Range  TV, testing the M14 against an AR15 and a MAS.  While I have been told  for years and against my own experience the M14 would laugh at a little sand, the video and reality seems to indicate different.

The boys tested the same guns earlier in the mud.  The M14 performing exactly as expected for those who know them well.

My personal favorite gun blog, that is not this one, had a few words to add to the heated debate 24 hours after the festivities started with my post.    Over on, a lively discussion is still on going with more than a handful of real world military users speaking up.

If you are not familiar with It is superb and is highly recommended daily reading. Description of the blogs writer and mission statement. “WeaponsMan is a blog about weapons. Primarily ground combat weapons, primarily small arms and man-portable crew-served weapons. The site owner is a former Special Forces weapons man (MOS 18B, before the 18 series, 11B with Skill Qualification Indicator of S), and you can expect any guest columnists to be similarly qualified.”

Some more discussion and viewpoint comes from a fine blog. which has as a focus the owners personal quest to becoming a true rifleman and the experiences and epiphanies he has along the way.

Following some of the shrill screaming, rending of clothes and gnashing of teeth has shown many missed the point, or became so angry they did not give any consideration to the post.  Most often seen is the claim the point of the article was to talk up the AR10 or AR15, when that was obviously not the goal to anyone who can comprehend English. Nor was it an attempt to get anyone to hate the gun.  It was a discussion of its shortcomings and the honest assessment that it is far from perfect all powerful or even a decent DMR weapon, and the caliber of the gun was not even discussed. That being the other claim, that some how we were ragging on the 308, though no mention of the effectiveness was even hinted at.

While many love the rifle, nothing will change our minds from the simple truth of it. While it is  better than a tamato stake. it is far from what its blind followers would like to think.

Lastly, I am re sharing the link to some informal shooting of a custom M14 from over a year ago. While not intended to be conclusive proof of anything, it was a fun comparison of some of the classic infantry weapons of yesteryear including the M1903, M1 Garand of course the much beloved( though undeserved ) M14



I recently picked up a 14.5″ AR upper and, as I wanted to be able to run it on one of my non SBR lowers, I had to have an extended flash hider pinned/welded on to meet minimum barrel length laws.

After picking it up from the from the smith and placing the two flash hiders next to each other, the absurdity of it all struck me.


That this tiny bit of difference would make all the difference between being completely legal or getting to spend time in a federal “pound me in the ass” prison, to quote the cinema classic Office Space.

But hey, if you can’t count on the government for arbitrary regulation, who can you count on??
