The Best Bolt Carrier Group for AR-15. If you are looking to build an AR-15 for hard use, to standards that exceed Mil-Spec expectations, then look no further than Sons of Liberty Gun Works. Every component of this bolt carrier group has been properly heated treated and is designed for reliability and longevity.

The carrier is machined from AISI 8620 aircraft quality steel and features a full-auto profile with a durable manganese phosphate coating. The bolt is made from Carpenter Technology No. 158 Alloy and has been magnetic particle inspected as well as high pressure tested to ensure that it will run for many years to come.

Every part of a BCG has a specific function and must be made to the highest standards so it doesn’t fail. The gas key is made from 4130 Chromoly steel and has grade eight properly staked hex screws to prevent it from coming loose over time. This SOLGW bolt carrier group is a great choice if you are building or upgrading an AR-15.
