Colt M4 Enhanced Patrol Rifle 5.56 NATO Complete URG

A 14.5" upper with a Centurion M-LOK handguard and a pin and welded extended A2 flash hider.

Colt has been the go-to name for tactical and duty rifles for years. The Colt M4 EPR Carbine with is designed to meet the rigorous demands of law enforcement and military operators. When you think of a rifle that's built for duty, Colt should be the first name that comes to mind. Now available as a complete URG ready for your lower.

Colt factory new. This is the upper receiver of the Colt EPR rifle with M-LOK thin performance rail from Centurion. The Colt Enhanced Patrol Rifle is an upgrade to the 6920 family of Colt rifles. The EPR is designed for law enforcement, but available commercially as well.

The Colt Enhanced Patrol Rifle (EPR) is the next evolution in the world's most dependable, thoroughly field-tested patrol rifle. Featuring an extended M-LOK handguard that accepts modular rail segments for mounting a wide variety of optics, weaponlights, bipods, lasers, and ergonomics-enhancing accessories. The barrel has a Colt factory low profile gas block. The EPR upper receiver group features the Centurion ultra-thin high performance rail, and is a hot looking upper and makes for a fun to shoot gun.

This upper assembly comes to us both new as a factory replacement and as a take-off from a factory new Colt EPR duty rifle. This tranche of Colt uppers features either the Cerro forged upper receiver without CAGE code or a Brass Aluminum forged upper with CAGE Code. Colt is producing both. If you have a preference, let us know. The Centurion rails were changed to have engraving and not white etched lettering.

These have 14.5" barrels that ARE pinned and welded to 16", so no NFA paperwork. Charlie's sends these out to be pinned and welded. They come standard with the extended A2 flash hider, but you can upgrade to a Surefire, Rugged, or Dead Air muzzle device, especially if you plan on running suppressed.

Note: If you want to upgrade your muzzle device, ask a Charlie's team member, but what you will do is to purchase the muzzle device online with the same order as your rifle. There is no extra charge beyond the price of the muzzle device. No, you get no credit for not selecting the standard. We put that in the bin for the extra handling.

What sets this Colt 14.5" EPR upper apart?

It's built by Colt, a brand synonymous with quality and durability. The rifle is engineered for high performance in any condition—rain, mud, or the back of a patrol car. When you invest in a Colt, you're not just buying parts; you're buying peace of mind. Don't miss the opportunity to own equipment that comes with Colt's assurance of quality and is enhanced for modern-day requirements.

Imagine having a rifle that's not just reliable but also versatile. A pin and welded 14.5" barrel still maintains the legal 16" requirement and doesn't give up the velocity of shorter SBR barrels. It's forgiving with different types of ammo and has shorter dwell time than a 16" which helps suppressed shooting. The Centurion M-LOK rail is thin, easy to handle, and aligns perfectly with the Colt receiver. The Colt EPR barrel is military-grade phosphate-finished and chrome-lined. This increases durability and anti-corrosion properties, making it a low-maintenance choice. You won't have to second-guess your equipment when you're in the field. The MPI HP tested BCG ensures reliability.
