Power your rifle with a reliable, duty-ready bolt carrier group from a brand builders trust. The LBE Unlimited Complete BCG (M16 Style) is tuned for 5.56x45mm NATO systems (also compatible with .223 Rem), featuring a black phosphate finish for proven wear resistance and easy maintenance. Built around an 8620 steel carrier in the classic M16 profile, this drop-in BCG delivers smooth cycling, long service life, and consistent lock-up—whether you’re assembling a new upper or refreshing a high-round-count carbine.

True M16 Carrier Geometry: Heavier, full-auto profile for stable recoil impulse and improved dwell.
5.56 NATO Confidence: Optimized for standard gas systems; works across typical 5.56/.223 AR-15 configurations.

Complete & Ready: Arrives fully assembled—bolt, carrier, gas key, firing pin, cam pin, and retaining pin.
Carrier Material: 8620 steel, M16-style (full-auto) profile for durability and smoother cycling
Caliber/Application: 5.56x45mm NATO / .223 Rem (AR-15 pattern)
Finish: Black phosphate (manganese phosphate/Parkerized style) for rugged, non-glare protection
Build Type: Complete BCG (no additional small parts required for installation)
Identifiers: M16BLT (SKU) • UPC 765857617305

Smooth, Consistent Cycling: Proper carrier mass helps maintain timing across a range of gas settings and buffer weights.
Durable, Easy-Care Finish: Phosphate’s micro-texture retains lubricant and shrugs off range grime.
Drop-In Simplicity: No part chasing—install, lube, and get to the line.
Proven Pattern: M16 style is the benchmark layout for hard-use ARs, training carbines, and defensive setups.
General-purpose carbines for training, practice, and home protection
Duty/defense builds where consistent reliability outranks flash
Competition/range rifles that see high round counts and fast maintenance turnarounds
Spare/refresh kits to keep on hand for fleet upkeep or travel
Inspect & Lube: Apply quality CLP or oil to rails, bolt lugs, cam path, and gas rings before first use.
Headspace Check: Particularly when mating to a new or unknown barrel extension.
Gas Key Screws: Verify they’re tight and properly staked from the factory before first firing session.
Break-In: Run a few well-lubed mags; phosphate surfaces burnish and slick up with use.
Clean Regularly: Focus on the bolt tail, carrier bore, and gas key interface; re-oil after each session.
