COLT M4 COMMANDO CR6933 SBR - 11.5" 5.56 NATO SHORT BARREL RIFLE, 1/2X28 THREADED
The Colt M4 Commando CR6933 is a semi-auto 5.56 NATO short barrel rifle built around an 11.5" barrel with a 1:7 twist, a chrome-lined bore, and a phosphate exterior. An A2-style front sight gas block with an integrated front sight post, standard M4 furniture with carbine handguards, and an adjustable M4 carbine stock give it the classic Commando profile in a closed-bolt rifle.
With the stock collapsed, the CR6933 measures 27.5" overall, and it extends to 30.75". It weighs 6 lb 3.36 oz. The muzzle is threaded 1/2x28 and ships with an A2 flash hider, and a 30-round magazine comes in the box. If you're comparing options, see our full lineup of short barrel rifles.
CAPITOL ARMORY'S OPINION
If you want a Commando, the CR6933 is the genuine Colt article. The 6933 set the standard that a lot of compact rifles still follow, and with availability as limited as it is, we see plenty of collectors hunting these down alongside shooters who plan to run them hard.
We think 11.5" is a sweet spot for 5.56 NATO. You keep enough velocity for the cartridge to do its job, and the rifle stays short enough to move easily in tight spaces like hallways and vehicles. Colt chrome-lines the bore and phosphate-coats the exterior, so the barrel is built to hold up to a lot of use.
The CR6933 also makes a great host for a compact suppressor. Pair it with something like the HUXWRX FLOW 556K or SilencerCo Saker ASR 556K, and you end up with a short, quiet, easy-handling setup for professional use, home defense, or a day at the range. The Commando design has a long history with military special operations units and federal law enforcement agencies, and that track record is a big reason professionals keep choosing Colt.
