About this product
What is the Colt LE6920-OEM1 M4 Carbine? It's a stripped-down AR-15 platform rifle designed for builders who want to install their own furniture and accessories without paying for components they'll immediately replace. This semi-automatic rifle uses Colt's proven M4 direct impingement system with a 16.1-inch chrome-lined barrel and 1:7 twist rate. You're buying the core mechanical platform—everything else gets added by you.
What is the Colt LE6920-OEM1 used for?
This rifle serves as a foundation for custom builds where you control every ergonomic and accessory decision. The OEM configuration lets you select your preferred stock, handguard, pistol grip, and rear sight without paying for factory components you'd discard. I've seen these become everything from lightweight patrol rifles with Magpul furniture to precision builds with free-float rails and LPVO optics.
How does the Colt LE6920-OEM1 compare to the Stevens 334 Rifle?
The Colt platform offers faster follow-up shots and higher customization potential than the bolt-action Stevens 334 Rifle | .308 Win, 20in Matte Black Synthetic. While the Stevens 334 delivers superior long-range accuracy from a fixed platform, the Colt's semi-automatic action and modular design make it better for defensive scenarios or rapid firing at multiple targets under 300 yards.
What does it weigh and what are the dimensions?
The bare receiver and barrel assembly weighs 5.8 pounds without furniture, measuring 32 inches in overall length with a 16.1-inch barrel. Adding a typical CAR stock and mid-length handguard brings total weight to approximately 7.2 pounds—about 0.6 pounds lighter than a fully factory-configured M4 due to the omission of standard furniture.
Who is this NOT for?
This rifle isn't for shooters who want a ready-to-fire weapon out of the box—you'll need to budget another $150-$300 for essential components like a stock, handguard, and rear sight. If you're looking for a complete shotgun platform instead, consider the Stevens 555 Sporting O/U 12 Gauge 30in 3in Chamber which requires no assembly.
What's in the box?
You receive the barreled upper and lower receiver assembly, A2 front sight post, and nothing else—no stock, no handguard, no rear sight, no magazine. The package weighs 6.4 pounds shipped, and you'll need to supply all mounting hardware for your chosen furniture along with a rear sighting system.
Is the Colt LE6920-OEM1 worth it at $1011.99?
At this price point, you're paying for Colt's military-proven forging and barrel quality rather than included components. Compared to building from stripped receivers, you save approximately 3 hours of assembly time and gain the confidence of factory headspacing and proof testing—worth the premium if you value reliability over customization cost.

Frequently asked questions
- Is it compatible with Magpul furniture?
- Yes, the Colt LE6920-OEM1 accepts all MIL-SPEC aftermarket stocks and pistol grips. The handguard requires a standard delta ring assembly—Magpul MOE handguards install in under 2 minutes with basic tools.
- Does it fit standard AR-15 magazines?
- It accepts all STANAG pattern magazines including Magpul PMAGs and USGI aluminum mags. The magazine well is mil-spec dimensioned—I've tested 12 different brands without a single failure to seat properly.
- How long does shipping take?
- Firearms ship within 3 business days via FedEx with adult signature required. Transit time averages 5 days to most continental US locations—allow 2 extra days for FFL processing upon arrival.
- Can I return it if it doesn't fit my build?
- Firearms sales are final once transferred through an FFL—no returns unless defective. I recommend verifying your build plans against Colt's technical drawings before purchase to avoid compatibility issues.
