Product Description
Update, October 9, 2026: ATF no longer requires a Form 4, tax stamp, fingerprints or registration for suppressors, short-barreled rifles, short-barreled shotguns or AOWs. They now transfer on a standard Form 4473 with a background check. Anything below that mentions a Form 4, a wait or a tax stamp was written before this change. What changed
Colt: The Original M4 — America’s Military Rifle Since 1964
Colt’s Manufacturing has produced the M16/M4 family for the US military longer than any other manufacturer. The AR-15 and M4 are Colt designs — every other manufacturer builds on a pattern Colt developed and delivered to USSOCOM, US Army, USMC, and over 40 allied militaries worldwide. Colt’s Law Enforcement and EPR series are manufactured to the same specifications as Colt’s government contract rifles — using the same factories, same tooling, and same quality standards. When you buy a Colt SBR, you are buying the same platform used by US Army Rangers, USMC infantry, and SOCOM units.
The Colt EPR GEN II 5.56 11.5″ is the second-generation Enhanced Patrol Rifle platform at compact 11.5″ barrel length. The GEN II improves on the original EPR with refined upper receiver geometry and enhanced components. At 11.5″, this is Colt’s dedicated CQB and vehicle SBR — the same barrel length used on the Colt M4A1 CQBR (Close Quarter Battle Receiver) adopted by US SOCOM. Black finish, 30-round capacity.

FAQ — Colt SBR Series
What makes Colt SBRs different from other AR-15 SBRs?
Colt’s Manufacturing has built M4 Carbines for the US military since 1994 — over 30 years of continuous government contract production. Colt milspec tolerances are the standard against which all other AR-15 manufacturers are measured. If a competitor says their rifle is “milspec,” they mean it meets Colt’s M4 specifications. A Colt is the actual thing.
What is the difference between the LE6921 and the EPR series?
The LE6921 is Colt’s standard Law Enforcement M4 — the same basic platform issued to police departments and military units worldwide. The EPR (Enhanced Patrol Rifle) series adds enhanced features over the base LE6921: match-grade trigger components, enhanced furniture, and refined ergonomics for professional users who demand more than baseline M4 specs.
