STAG ARMS LEFT AR15 BOLT CARRIER with KAK Duel EJECTOR BOLT FOR AR-15 5.56/.223/300BLK NITRIDE LEFTY HANDED Melonite M16

STAG ARMS LEFT HANDED AR15 BOLT CARRIER WITH UPGRADED KAK DUEL EJECTOR BOLT FOR AR-15 5.56/.223/300BLK NITRIDE LEFTY HANDED BCG (See below for KAK industries very high quality and great replacement for the Stag BC and KAK Bolt.) 

This bolt carrier assembly is designed to work with any upper receiver designed for left hand ejection in either 5.56, .223, or 300 BLK. 

The salt path nitride process (also known as QPQ) creates a much harder surface that is, easy to clean, will run with less than ideal lubrication and resists wear for a lasting corrosion resistant durable finish.

We have upgraded the bolt to a KAK Industry K-SPEC Dual Ejector Bolt for great reliability and consistency to the ejection pattern.
