Instant, No-Fumble Bolt Release
Pull back slightly on the bolt handle and the bolt releases. Drop-in
part does away with the factory two-handed, push-pull, lift and
let-go bolt release mechanism. Made from hardened, heat-treated,
durable steel. Requires absolutely no fitting for a faster, easier to
shoot 10/22.
