The Atrius Development Group is known for its innovative fire control systems, particularly the FORCED RESET SELECTOR. This product is designed for AR-15 owners who want a robust, fast-handling selector with three distinct modes for confident control. The selector is compatible with mil-spec AR15 fire control groups and requires no modifications, making it a versatile tool for enhancing semi-auto performance. The group also offers the 3-Position Forced Reset Selector Ambi, which provides three firing modes—Safe, Semi (Traditional), and Full-Semi—through a forced reset selector.
All Toolcraft BCG bolts are shot-peened, MPI and either batch or individually HPT to ensure quality and reliability. Made from either mil-spec Carpenter 158 steel or high strength 9310 steel, bolt carrier groups from Toolcraft are guaranteed to perform like new for thousands and thousands of rounds. You cannot buy a better bolt carrier group than a Toolcraft.
