bolt carrier groups


Troy Alpha Carbine

There seems to be some debate as to the usefulness of the new style collapsible stocks being used on carbine and full sized rifles. The Alpha Carbine from Troy uses their M7A1 PDW stock on their rifles. It is not a drop in stock that works with your standard bolt carrier; you have to use the special proprietary bolt carrier group provided with the stock in order to use it with your rifle. PDW stocks tend to be more practical on an SBR or actual PDW build than on a 16″ or 18″ carbine. (GRH)

The OMEN Match 7mm Rem Mag is a new offering. The 7mm Rem Mag is widely popular due to it’s performance and low recoil. The 7mm Rem Mag is an inexpensive cartridge to shoot. The OMEN represents a paradigm shift from traditional bolt-action towards precision MSRs (Modern Sporting Rifles). Shoot one for yourself and experience first-hand an advanced evolution in MSRs.

.458 SOCOM

A large caliber option for the AR-15, the .458 SOCOM is rather popular as a hog hunting platform. Only a few companies actually make dedicated .458 rifles, primarily Wilson Combat and Rock River Arms. You can still build your own just by getting the barrel and bolt carrier group and installing them on your choice of upper. (GRH)

Perhaps most widely known for their Dragon muzzle brakes and enhanced bolt carrier groups (not to mention their bad ass slow motion videos), Lantac USA has rapidly expanded its product line to encompass other parts and components, as well as complete rifles.

C is for cookie and it’s good enough for me...

So basically what you’re saying is everyone who’s recently built their own AR-15 or AR-10 rifles pretty much made a copy of something you can find off the shelf at Sports Authority or Cabela’s or whatever shop you go to?

The use of the “cookie cutter” idiom was in reference to the mass produced, already assembled rifles that use the same particular components to create an existing designated model.

So, if I wanted a chocolate chip cookie, I would expect it to look like a chocolate chip cookie based on the components (ingredients).

If I wanted a Colt 6920MP, which is the Magpul series, then like a cookie, I would expect it to look like the advertised model with the Magpul furniture.

Deviating from the set parts list breaks the mold, the whole think out of the box kind of thing; more unnecessary cliches. For example, the owner of these 3 firearms; an AR pistol, AR-15 and AR-10 used both similar and different parts. All different uppers, different lowers, different stocks, different sights, different muzzle devices, different handguards…about the only thing the same are the grips.

What you’re doing is generalizing the key components that every AR (or every firearm really when proper terminology is applied) needs. Just because someone uses an upper, lower, stock, grip, barrel, handguard, trigger & bolt carrier group, doesn’t mean their rifle will be a cookie cutter, off the shelf model AR.

In essence it would be like saying every human being is the same; which isn’t true, we all (twins, triplets etc included) differ in our own certain ways.

So let’s close this with visuals…

Cookie cutter AR…

Not cookie cutter AR…

Oh…and an actual cookie cutter AR.

Colt LE901-16S

A 7.62x51mm/.308 direct impingement AR from Colt. What makes it unique among the rest of the crowd is the conversion kit that allows you to use a 5.56x45mm/.223 AR-15 upper. The 901 has some proprietary parts such as the bolt carrier, trigger group pins and charging handle. It’s been out on the market for a few years but has been replaced by the more modular M.A.R.C 901-16SE series. The latter does away with the bulky quad rail and is 1 lb lighter. (GRH)



U.S made Uzi clone sold by Century Arms. The UC-9, like the original Israeli Uzi is chambered in 9x19mm but you can convert it to .45 ACP if you have the barrel, bolt carrier group and magazines. In the second photo you can see the front end assembly, the barrel nut and tab that secure the barrel in place. Some of these Uzi clones have the barrel nut welded so you can’t swap out the 16″ barrel to drop in a 10″. (GRH)
