Colt M16 Upper Group 20In Moe W/ Bcg & Charging Handle

The Colt M16 Upper Group 20In MOE with BCG & Charging Handle is a complete, ready-to-assemble upper receiver built on the proven M16 platform. This is the classic flat-top design you'd find on military-spec M16A2 and M16A4 rifles—20-inch government-profile barrel with a 1-7 twist, chrome-lined bore and chamber for durability and easy cleaning. It ships with everything you need to run it: bolt carrier group, charging handle, and a Magpul MOE handguard that lets you accessorize exactly how you want. Whether you're building a DMR, recce rifle, or just want a modular upper on a favorite lower receiver, this is straightforward, no-nonsense engineering.

Magpul MOE handguards are a favorite for a reason—lightweight, comfortable in any weather, and they give you genuine modularity without breaking the budget. The military-grade barrel and chamber specs mean this upper will handle full-power 5.56 NATO or .223 Remington safely, and the 1-7 twist stabilizes everything from 55-grain training rounds to 77-grain match ammo.

If you're swapping uppers between lowers, building your first AR, or just need a complete, tested upper assembly, Colt's direct manufacturing and decades of military service history speak for themselves. Pair it with a lower receiver of your choice and you've got a functional rifle—no mystery parts, no guessing.

Frequently Asked Questions

What lower receiver is compatible with this Colt M16 upper?

This M16 upper uses a standard M16/AR-platform receiver extension and will mate with any M16 or AR-15 lower receiver. Your lower just needs to be rated for the caliber and pressure you plan to shoot; a standard mil-spec lower works fine.

Is this upper ready to shoot out of the box?

The upper comes with the bolt carrier group and charging handle installed, so all you need is a compatible lower receiver, magazine, and ammunition to fire it. It's a complete upper assembly.

What ammunition can I safely shoot through this barrel?

The 1-7 twist and chrome-lined chamber handle full-power 5.56 NATO and .223 Remington safely. The 1-7 rate is fast enough to stabilize heavier rounds and works reliably across the full spectrum of commercial and mil-spec ammunition.

Can I add accessories to the MOE handguard?

Yes—Magpul MOE handguards accept standard Picatinny rail-mounted accessories. The modular design is one of the main advantages here: mount lights, laser designators, vertical grips, or bipods as your mission requires.
