The Colt M4 Commando CR6933: A Texas-Ready SBR
When you need a short-barreled rifle that works every time you pull the trigger, the Colt M4 Commando CR6933 delivers. This isn’t some boutique build or experimental platform—it’s the same system trusted by military and law enforcement units for decades, now available in a compact 11.5-inch configuration that maintains terminal ballistics while reducing overall length.
What Makes This Colt SBR Different
Most SBRs on the market are built from aftermarket parts or modified from longer rifles. The Colt CR6933 comes from the factory as a complete short-barreled rifle system. Every component is matched and tested to Colt’s military specifications. The 11.5-inch barrel with 1:7 twist stabilizes both light and heavy 5.56mm loads effectively, maintaining velocity better than you’d expect from a barrel this short. The closed bolt semi-auto action provides consistent lockup and reliable feeding that you can count on when it matters most.
Texas Applications
Here in Texas, we understand that different terrain calls for different tools. The Colt CR6933 shines in situations where a full-length rifle would be cumbersome but a pistol doesn’t provide enough ballistic performance. Whether you’re navigating thick brush in East Texas, securing a ranch property in the Hill Country, or keeping it ready for urban defense scenarios, this SBR provides the right balance of power and maneuverability. The adjustable stock lets you tailor length of pull for body armor or regular clothing, and the 27.5 to 30.75-inch overall length means it stores easily in vehicles or tight spaces.

NFA-Regulated Firearm — ATF Form 4 Required
This is a short-barreled rifle (SBR) regulated under the National Firearms Act. Purchase requires an ATF Form 4 transfer, a $200 federal tax stamp, and approximately 30–120 days of ATF processing (eForm 4 is typically faster than paper). The firearm ships to a licensed FFL/SOT dealer of your choice; you take possession only after ATF approval.
SBRs are currently legal to own in most U.S. states. They remain prohibited or restricted for civilian possession in California, New York, New Jersey, Washington D.C., Hawaii, Iowa, Rhode Island, and Washington State. Check your state and local law before ordering. By placing an order you affirm that possession is lawful in your jurisdiction and that you are 21+ with no prohibiting factors under 18 U.S.C. §922(g).

Ran 500 rounds of mixed ammo without a single malfunction. The 11.5″ barrel handles surprisingly well in tight spaces. Colt quality is worth the price for a duty-ready SBR.

Perfect for ranch patrols where I need something compact but effective. Threaded muzzle accepts my suppressor easily. Only complaint is the basic handguard, but that’s an easy upgrade.

This is my go-to truck gun. Fits behind the seat perfectly and I trust it to work if needed. The lifetime warranty from Colt gives me confidence in the investment.
