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 Pro is the top-tier model in Colt’s Enhanced Patrol Rifle line — the GEN II Pro represents the refined, enhanced-feature version of the GEN II platform. At 11.5″ barrel length it is optimized for close-quarters and vehicle use. The EPR GEN II Pro is built on Colt’s standard M4 lower architecture with GEN II upper improvements and Pro-tier enhancements including superior trigger components and furniture. This is a serious SBR for professional users.

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.
