Toolcraft left handed Bolt Carrier Groups ship FREE.
Your Left-Handed AR15 Build deserves the best quality BCG you can get - Toolcraft!
This quality Toolcraft bolt carrier group has all the outstanding specs of the right-handed Toolcraft BCG, but it's a lefty. Both the carrier and the bolt are the exact mirror image of a traditional right-handed BCG. Use this left-handed BCG in a left-handed build, or as a spare BCG for your complete left-handed rifle.
The extremely hard Black Nitride finish results in less friction and smoother, more reliable function. Easy clean-up is a nice bonus. The rich black color on these BCGs looks great on the Black Rifle!
This is a .223/5.56/300 Blackout bolt carrier group.
Will not work with 6.5/6.8/308 etc.
