Toolcraft Black Nitride Bolt Carrier Group - 158 MPI

This black nitride BCG from Toolcraft is a popular choice for AR-15, M4 and M16 builds due to its mil-spec design and lifetime warranty. The bolt is made from 158 steel while the carrier is made from 8620 tool steel. It is shot-peened and magnetic particle inspected before being made available for sale and has a variety of other top-of-the-line features, including:

  • Mil-spec extractor spring, black extractor insert, Viton O-ring
  • Tool steel extractor
  • Shrouded firing pin
  • Mil-spec 4130 steel gas key attached with Grade 8 hardware and properly staked
  • Caliber: .223 / 5.56 / 300 Blackout

We believe in quality and reliability when choosing a bolt carrier group, so we only sell fully assembled BCGs from Toolcraft. We don't add any inferior plating to raw carriers or use random bolts to complete our setups. Everything is assembled and inspected by Toolcraft, inspected again by our team and sold straight to the customer. Contact us if you have any questions!

5 of 5 Another happy purchase. June 16, 2020
Reviewer: Ken from The Hills  
As others noted- great fit and finish. No tooling marks and everything looking good to go. Screws properly staked, all in spec. Check head spacing, throw some lube on, drop it in, go shoot. Keep shooting and lubing, clean it- repeat. Can’t complain. We’ll see how it ages and maybe report back when the round count is higher- but as stands, I’d buy another for my next build and recommend to a friend.

5 of 5 Best BCG for price 6 out of 5 stars April 23, 2020
Reviewer: Travis Mattson from Minnesota  
I have used BCM, DPMS, COLT, AO ,PSA, and others and these bolts and blow them away in dit and finnish, every corner and edge is polished. Surfaces are free of machine marks and very smooth. Nitride finish cleans easier.
