Also, a great alternative barrel to the M4 for your M4 6933 Commando build, or other SBR builds. 11.5" is actually the best length for an SBR with a carbine gas system. Cycles better than 10.3" or 10.5, but it is a little longer. You won't want this for a true Mk18 build, but not ever SBR has to be a Mk18. Try pairing this barrel with a nice KAC RAS and good flash hider or suppressor. Suppressed fire works great with 11.5"
Gas port measured with pins at 0.070", and maybe a little under.
- 4150 CMV steel alloy with chrome lining, exterior is phosphate coated to military standards.
The heavy profile and is exactly a SOCOM profile, but does not have the M203 cuts.
Your choice of factory barrels: one with front sight base removed, and showing small taper pin grooves from where the FSB was pinned, and also the choice of a virgin option with no pin grooves, having never had a front sight base attached. Both identical barrels. We get very few in that are virgin barrels, and most come in with FSB removed.
Barrels will be marked with CAGE code marking "13629 MP 5.56 NATO 1/7"
As you may know, Colt changed to cage codes on their barrels around a number of years back.
Weight is 26 oz.
We take special care in bringing you the best in short barrels, and use the best artisans, both in-house, and in our extended supply chain, when something has to be engineered to a Colt production barrel. Our collectors and cloners will want the 10.3" barrel for historical accuracy. The Daniel Defense is a great option, as it is now being used by US Special Forces in limited numbers, and is readily available and affordable. For more authenticity, choose a Colt 10.3" barrel.
Shooters and law enforcement typically choose the 11.5" barrel, as it has better overall performance, especially in the heavy (SOCOM) profile. Our LE customers tell us that they will only use Colt barrels in 10.3" to 14.5" lengths. Colt truly does dominate that market, while other barrel companies own the long-range and sniper market.
