The Spike’s Tactical M16 bolt carrier group is the same complete, M16-profile BCG that Spike’s fits to its own factory-built rifles. It drops into AR-pattern uppers chambered in .223 Remington / 5.56 NATO and ships complete and ready to run.

The carrier is phosphate coated inside and out and is paired with a mil-spec bolt. The M16 profile has the full-weight carrier tail, which adds mass to the reciprocating group. That helps keep the cycle smooth and the timing consistent, especially in carbine-gas builds. The carrier is laser engraved with the Spike’s Tactical spider logo.

Features:

• M16 profile, complete and ready to run
• Phosphate coating inside and out
• Mil-spec bolt
• Laser engraved with the Spike’s Tactical spider logo

Fitment: AR-pattern builds chambered in .223 Remington / 5.56 NATO. Lubricate the carrier and bolt before installing. Have headspace checked with gauges whenever you pair a new bolt with a barrel, then run a few magazines before trusting the rifle.
