This weapon is an upgrade to the whole squad layout, and you can even work it in to combined arms warfare,” said Sgt. Patrick Nissen, a 3ID. “I shoot long-range, both in the Army and recreationally, and I really like getting down behind this weapon, it is very comfortable, it is a great rifle, and I really do enjoy it”

Now that is a perfect example of toeing the party line. Or the Sgt. really wants one of those sweet retirement jobs at HK like the Generals get. Way to hard sell that rifle Sarge.

The whole intent for this is new equipment training,” said David Parris, a former infantry Soldier, and one of the civilian experts from the Army’s Tank-automotive and Armaments Command, which helped field the guns. “We have given them a rifle that is precise and capable of closing the capability gap of 300-600 meters, which means it fills the maximum firing distance gap between the standard-issue rifle and the sniper rifle.”

The rest of this HK advert, Army talking point and buzz words that are essentially meaningless.

Raider Soldiers once again led the way in modernization when they fielded the U.S. Army’s new Squad Designated Marksman Rifle, SDMR, last week on Fort Stewart, Ga. The fielding process ended with a familiarization firing at the base’s sniper range on June 5th, 2020.

The team that conducted the live fire consisted of noncommissioned officers from all over the 1st Armored Brigade Combat Team, 3rd Infantry Division. They were the first in the Army to field the SDMR, named the M110A1. They started their training earlier in the week with initial familiarization in a classroom setting. This enabled the Soldiers to become educated with the new weapon system before conducting live fires.

After the initial training, where they learned about the assembly and disassembly, functionality, operation, etc, the Soldiers took to the sniper range for zeroing and confirming with a civilian team from the Tank-automotive and Armament Command out of Detroit.

“The whole intent for this is new equipment training,” said David Parris, a former infantry Soldier, and one of the civilian experts from TACOM. “We have given them a rifle that is precise and capable of closing the capability gap of 300-600 meters, which means it fills the maximum firing distance gap between the standard issue rifle and the sniper rifle.”

The SDMR fires a 7.62x51mm NATO round and comes equipped with a variable zoom scope. The manufacturer also added a bi-pod, adjustable butt stock, and an upgraded trigger to enhance the weapon system’s precision fire capabilities.

Once the fielding process is complete, these NCOs will be able to take what they have learned and share it with the Soldiers of their respective units. This will be another way the Soldiers of Raider Brigade build and maintain lethality.

North Korean Helical 150 Round AK Magazine

“North Korea fields a dizzying number of weapons, both small arms and more complex systems like tanks and airplanes. The common thread connecting these weapons together? Almost all of them are copies of other country’s designs. Tanks? Soviet copy. Airplanes? Soviet surplus. Standard issue rifles? Soviet copy. But, one of their own indigenous inventions is a large-capacity magazine.

This helical magazine is intended for use with the North Korean Type 88, an AK-74 copy.

The United States Marine Corps too is reportedly developing a high-capacity magazine option for their new service rifle, the M27. The magazine would significantly increase the individual rifleman’s firepower, perhaps making up for getting rid of the Squad Automatic Weapon.

Still, the high-capacity drawbacks sometimes outweigh the benefits. The most significant drawback is reliability. Unlike traditional magazines which rely on a wire spring to keep usually 30 or so cartridges pressed toward a gun’s chamber, drum magazines have to keep anywhere from 50 or more cartridges pressed towards the chamber. Keeping this many rounds under tension requires a large spring. This increases the tension inside the magazine, and can sometimes result in jams or misfeeds, adversely harming reliability.

The Type 88’s extended magazine may hold as many as 150 rounds, though this is hard to confirm. If 150 is an accurate number, the weight of the cartridges alone, not including the weight of the all-metal magazine would be over 3.5 pounds, or over 1.6 kilograms.

As the magazine is attached to both the magazine port and to the underside of the barrel, the Type 88’s balance would shift forward. Needless to say, the magazine would make handling the Type 88 slower and more unwieldy, though accuracy during fully-automatic fire might actually improve, as the rifle barrel could experience less “climb” upward.

This odd-looking magazine seems to have been originally issued to Kim Jong-un’s personal bodyguards, who carried three magazines, one inserted in the rifle and two in reserve. That gave them an estimated total of 450 rounds of 5.45×39 ammunition, equivalent to 15 regular 30-round capacity magazines. Talk about packing a big punch.”


If you wondered how these work..

Some Thompson History

I found this series of pictures on my old computer yesterday while looking for something else. I don’t remember where or what show it was I took these but I am pretty sure I never put these on the website . I’m thinking it was one of the NRA shows.

Anyway. You can see a lot of Thompson SMGs that are historically significant. Sorry I don’t remember enough about it to add in details.

Colt 607 Reproduction Buttstock

I learned something today I didn’t know. And that is the company above makes and sells reproduction Colt 607 stocks.


Yes I know that prices is as high as a Alabama meth head. It does appear to be an excellent repro from their pictures. You can probably guess how hard it is to find original 607 stocks and various parts now a days.

The Colt 607 was a carbine made during the Vietnam war era and that was the first collapsing stock. The 607 was part of the “CAR-15 family.

The Colt Model 607 was the first attempt to produce a “True Carbine” which had both a reduced barrel
length and collapsing buttstock. The 607 Models included; the 607 with 3-Way Fire Control Group
(Safe, Semi, Auto), the 607A with 3-Way Fire Control Group (Safe, Semi, Auto) the 607B with 3-Way Fire
Control Group (Safe, Semi, Burst). The model 607 used modified AR15/M16 furniture to include a
modified buttstock which allowed it to be extended or collapsed, as well as a shortened pistol grip and
shortened triangular handguards. The Model 607 had very limited production numbers and saw very
minimal use in the field by US Military Forces during Vietnam. There was a “Military Version” of the 607

Colt Model 607 – Flashhider Variations
The Colt Model 607 was most commonly found with a 3.5″ Moderator,
however as the photos above show it could have also been found with a  
3 Prong Flashhider and 4.5″ Moderator.

Here is one seen in the wild being used during the war.The fella in the far left is carrying one.

I have another little known fact for you below the picture.

“Wow cool, a Seal in Vietnam using the H&K 33 !” you are saying. Well you would be wrong. That is actually a liscensed copy of the 33 made by Harrington & Richardson.
