Colt LE6920-OEM1 M4 Carbine 5.56 NATO 16.1″ Matte Black
$1,124.64
The Colt LE6920-OEM1 M4 Carbine 5.56 NATO 16.1″ Matte Black is a factory-ready AR platform for custom builders. It includes a chrome-lined barrel, A2 front sight, and direct gas system — just add your own stock, handguard, and rear sight.
The Colt LE6920-OEM1 M4 Carbine 5.56 NATO 16.1″ Matte Black is a factory-ready, semi-automatic AR-platform rifle built for shooters who prefer to install their own stock, handguard, and rear sight. It comes with a 16.1-inch chrome-lined barrel, a 1:7 twist rate, and a direct gas operating system. This OEM configuration omits the buttstock, handguard, magazine, and rear sight so you can add the exact components you want.
| Manufacturer | Colt |
|---|---|
| Model | LE6920-OEM1 |
| Material | Chrome-lined barrel, carbon steel upper/lower receiver |
| Compatibility | AR-15 mil-spec handguards, stocks, and rear sights (per manufacturer specs) |
| Finish | Matte Black anodized |
| Weight | 6.0 lbs (approx., without furniture) |
| Condition | New |
Key Features
- Chrome-lined barrel (16.1″) — WHY IT MATTERS: Chrome lining extends barrel life and resists corrosion, so this rifle stays accurate round after round. The 1:7 twist stabilizes heavier 62-77 grain bullets, giving you flexibility for target shooting or home defense.
- Direct gas system with locking bolt — WHY IT MATTERS: This proven system reduces felt recoil and keeps the action running smooth. It’s the same platform used by the U.S. military, so reliability is built in.
- OEM-ready configuration — WHY IT MATTERS: You get a complete lower and upper receiver group minus the stock, handguard, magazine, and rear sight. That means you can pick a free-float handguard, a collapsible stock, and a red dot that fit your shooting style.
- A2 front sight included — WHY IT MATTERS: The front sight post is already installed and adjustable for elevation. Pair it with a rear flip-up or carry handle sight for a classic iron-sight setup.
- Matte Black finish — WHY IT MATTERS: The non-reflective matte coating reduces glare and blends in during low-light conditions. It also resists scratches and wear.
Who It’s For
This Colt LE6920-OEM1 is for the shooter who wants a quality Colt M4 platform but prefers to customize furniture and accessories. It’s a great choice for first-time AR builders who want a factory-assembled upper and lower without the guesswork. It’s also ideal for experienced shooters who already own a favorite stock, grip, and handguard and just need a reliable base rifle.
Pros / Cons
- Pro: Mil-spec chrome-lined barrel and bolt carrier group — proven durability for thousands of rounds.
- Pro: Lightweight at around 6 pounds without accessories, easy to handle for smaller-framed shooters.
- Pro: 5.56 NATO chamber accepts both .223 Remington and 5.56 ammunition.
- Con: The OEM configuration means you must purchase a stock, handguard, magazine, and rear sight separately. If you want a complete rifle out of the box, look at the Colt LE6920-MP-B.

FAQ
Does this rifle come with a rear sight?
No. The Colt LE6920-OEM1 ships with an A2 front sight but no rear sight. You’ll need to add a carry handle, flip-up rear sight, or a red dot optic.
What stock and handguard will fit this rifle?
Any mil-spec AR-15 carbine stock and carbine-length handguard (7-inch) will fit. The barrel nut is standard mil-spec, so drop-in or free-float handguards work. You’ll need a standard AR-15 buffer tube and castle nut for the stock.
Is this rifle California compliant?
No. This model does not include a magazine lock or compliant stock. Check your local laws before ordering. We offer compliance parts separately.
Can I use .223 Remington ammo in this rifle?
Yes. The 5.56 NATO chamber is safe for both .223 and 5.56 ammunition. Always follow safe handling practices.
What magazines does it accept?
This rifle accepts standard AR-15/M16 magazines (30-round PMAG or GI style). It does not ship with a magazine.
