Key Features

  • Custom-Ready Platform – Ships without stock, handguard, rear sight, trigger guard, or magazine. Why it matters: You save money on parts you’d replace anyway and build a rifle that fits your hands, your style, and your use case—from bench rest to patrol carbine.
  • Colt Chrome-Lined Barrel – 16.1-inch barrel with 1:7 twist, chrome-lined for longevity and corrosion resistance. Why it matters: A chrome-lined bore handles high-round-count training and harsh conditions without losing accuracy or cleaning easily.
  • Low-Profile Gas Block – Factory-installed low-profile gas block under a free-float handguard (not included). Why it matters: Allows you to mount any free-float rail system without gas block interference, improving accuracy and rail space.
  • Mil-Spec 7075-T6 Receivers – Forged aluminum upper and lower receivers with hardcoat anodized finish. Why it matters: These receivers are the same ones used in Colt’s military contracts—durable, tight-tolerance, and ready for thousands of rounds.
  • Right-Hand Operation – Standard bolt catch, charging handle, and safety selector on the left side. Why it matters: Familiar controls for right-handed shooters, compatible with nearly all aftermarket triggers, grips, and stocks.

Who It’s For

This Colt LE6920-OEM2 is built for the shooter who values a strong foundation over a finished product. It’s the right choice if you plan to install a high-end trigger like a Geissele or Timney, a lightweight carbon-fiber handguard, or a precision stock. It’s also ideal for gunsmiths and custom builders who want a Colt receiver set without paying for parts they’ll swap. If you prefer a turnkey rifle with all parts included, look at the standard Colt LE6920.

Pros & Cons

  • Pro: Genuine Colt mil-spec receiver set—no clone or import. You get the roll mark and the reliability.
  • Pro: Chrome-lined barrel and bolt carrier group (per Colt specs) mean long service life and easy cleaning.
  • Con: No stock, handguard, or sights included—you’ll need to budget for those parts. For a first-time builder, the total cost may exceed a complete rifle.
  • Con: The OEM2 ships with a standard trigger group (not included), but the lower is pre-drilled for a standard safety selector—some aftermarket triggers may require additional fitting.

FAQ

Does the Colt LE6920-OEM2 come with a bolt carrier group (BCG) and charging handle?

Yes, the OEM2 includes a Colt chrome-lined bolt carrier group and a standard charging handle. You get the BCG and charging handle in the box, but no stock, handguard, rear sight, trigger guard, or magazine.

What barrel twist rate does this Colt carbine have?

It has a 1:7 twist rate, which stabilizes heavier bullets (62–77 grains) common in 5.56 NATO loads. It also shoots .223 Rem perfectly well.

Can I use any AR-15 stock and handguard with this rifle?

Yes, the receiver extension (buffer tube) is mil-spec diameter, so any mil-spec carbine stock fits. The barrel has a low-profile gas block, so you can mount any free-float handguard that fits a .750″ gas journal. Standard delta-ring handguards also work if you install a standard barrel nut.

Is this rifle California-compliant?

As shipped, it has no stock or magazine, so it does not meet California’s assault weapon definition. You’ll need to add a fixed stock, a fin grip, or a mag-lock device to comply with state law. Check local regulations before purchasing.

What trigger guard does this lower accept?

It accepts standard AR-15 trigger guards (both standard and enhanced). The lower is not pre-drilled for a screw-in trigger guard, so you’ll need a standard pin-style guard or a drop-in unit like a Timney or Geissele.
