Colt LE6920-OEM1 M4 Carbine 5.56 NATO 16.1″ OEM AR-15 Rifle

Description

There are plenty of ways to end up with an AR wearing Magpul or B5 furniture, but most of them involve paying for factory plastic you pull off in the first week. Colt figured that out, and the LE6920-OEM1 is the result. It is the same M4 Carbine that built Colt's reputation, shipped without the handguard, buttstock, trigger guard, magazine, or rear sight. The core of the rifle is all there: forged aluminum receivers, a 16.1 inch chrome-lined barrel with a 1:7 right-hand twist, carbine-length direct impingement gas system, buffer tube, pistol grip, and the fixed A2 front sight gas block with the gas tube and USGI barrel nut already installed.

Why Builders Keep Grabbing the LE6920-OEM1

The appeal here is simple. You get real Colt quality, prancing pony on the receiver and all, as a foundation instead of a finished package. The USGI barrel nut and retaining ring accept most drop-in handguards, and free float rails designed around a standard barrel nut will work too. Add your preferred stock, trigger guard, and rear sight or optic, and you have a personalized carbine built on hardware that law enforcement and military users have trusted for decades. It is also a smart route for clone builders putting together an M4 or SOPMOD style rifle with correct Colt bones underneath.

A Barrel That Earns Its Keep

That chrome-lined 16.1 inch barrel is the heart of this carbine. Chrome lining shrugs off heat and corrosion through high round counts, and the 1:7 twist stabilizes just about everything from lighter 55 grain plinking loads up through 62, 69, and 77 grain match and duty ammunition. Chambered for 5.56 NATO, it runs .223 Remington without complaint, so ammo selection is wide open.

Setting Up Your Colt M4 Carbine OEM1

Finishing this rifle is an afternoon project, not a gunsmithing ordeal. Slide on a handguard, install a stock on the factory buffer tube, snap in a trigger guard, top the flat-top upper with an optic or flip-up rear that pairs with the A2 front post, and hit the range. At a 32 inch overall length with a matte black finish throughout, it stays every bit as handy as the standard 6920 once it is dressed.
