Colt SCW Stock Set

 Guest Post by Brent Sauer


          This article is intended to be about the very unique Colt Sub-Compact Weapon (SCW) stock set. However, we can’t talk about the SCW stock set without briefly talking about the background story of the SCW weapon itself.   

          Around 2005, the idea for the Colt Sub-Compact Weapon (SCW) was born when the law enforcement community asked for a weapon that was compact enough to fit in a motorcycle officers cargo saddlebag. Although the weapon was initially designed for motorcycle mounted officers, it quickly became apparent that the SCW would be a versatile weapon for use by security or military personnel in vehicles and in Close-Quarter Battle (CQB) roles also.

          After the design and testing cycle was completed, the SCW made its first public appearance at the 2008 Association of the United States Army (AUSA) show. This appearance got the weapon system noticed by some potential foreign customers. Israel adopted the SCW for their special forces and adoption by Mexico soon followed.

          The SCW was designed as a 5.56mm weapon and had a 10.3” barrel. The requirement was for the new weapon to give a responding officer rapidly deployable firepower greater than the service pistol that was carried. Initially fielded as a select fire weapon, it was also sold in semi-automatic only variants. What really made the design of the SCW stand out was its unique stock that folded in two places and could be extended/collapsed. The receiver extension design along with the unique bolt carrier/buffer assembly enabled the weapon to be fired with the stock folded or extended.

          The SCW stock kit consists of the following components:

1. Shortened Full-Auto Bolt Carrier Assembly

2. Receiver Extension

3. Buffer Spring

4. Receiver Extension Nut

5. End Plate

6. Collapsible/Folding Stock Assembly

7. Buffer (tungsten and steel construction just like other buffers)

          The stock body is hinged at the back of the receiver extension and folds 180 degrees to the left side of the weapon. When folded, the stock is parallel to the receiver. There is a detent that locks the stock in the folded position. In addition to the stock body folding, the butt of the stock folds under, and up at 90 degrees bringing the butt of the stock parallel with the stock comb.

          Another standout feature of the SCW stock kit is the unique buffer design. It is about a half of the length of a traditional carbine ‘H’ buffer. However, it has the same weight of an ‘H’ buffer at 3.6 ounces. The buffer actually ‘keys’ into the back of the bolt carrier about a quarter of an inch instead of the bolt carrier impacting the face of the buffer. During the firing cycle, the bolt carrier and the buffer move as a unit. This operating design eliminates the use of a buffer retainer in the SCW carbine.

          The complexity of the Colt SCW stock ended up being its undoing. In hard use the stocks were somewhat fragile. There were a lot of small parts used in production in addition to the molded plastic stock parts. Assembly of the SCW stock in the factory took a long time and was so complicated that Colt struggled to have an efficient assembly process for the stocks which hurt production forecasting and scheduling.

          In 2016/2017 Colt stopped using their proprietary SCW stock and changed to the Maxim Defense CQB stock for their SCW weapon. In an effort to clear out leftover inventory in the factory, Colt sold 11 remaining stock kits to Arms Unlimited. On 10 July 2017 Arms Unlimited made the stock kits available on their website for $800.00. After a couple of stock kits were not paid for by customers, the price went up to $1200.00 and those remaining stock kits were relisted on the website and quickly sold. Here is a look at the final site listing: https://www.armsunlimited.com/Colt-SCW-AR15-M4-Folding-Stock-Assembly-Kit-p/scw0921ck.htm

          Needless to say, these stocks are a rarity on the collector’s market. I know where four of them are, with my stock that is shown being one of them. I paid $1200 for my stock (with a broken folding lock detent) and was just glad to have the opportunity to get it. I have only seen one SCW carbine for sale and it is sitting on Gunbroker right now for $9995.00. It is supposedly one of only five SCW carbines that entered into the civilian market.

          Although many critics of Colt in the firearms community accuse Colt of not being innovative, you don’t have to look very hard to find innovative work that Colt has done. The SCW carbine, and the SCW stock set, is just one example.

  1. Thus is the sort of application the short 6940 can really shine in.

    The 6940 also seemed like a good, soldier proof M4 replacement.

    Oh well

  2. Motorcycle cops in a neighboring town have some sort of a locking mount on their motorcycles that allows them to carry some kind of AR-15 rifle in a muzzle-down configuration. The M4-style stock is unmistakable.

  3. This would be an excellent stock option for the Air Force GAU5 discussion too. The drawback being that it changes more than just the stock but the internals as well.
