I have 2 complete Bushmaster Bolt/Carrier assemblies for sale, one is new and one is used. The used one has 200-300 rounds through it and the new one has ummmm well zero rounds through it. Just hand cycled a few times. Both are Bushmaster and both are the non enhanced versions. The used one is in excellent condition.
$115 shipped for the new one and $105 shipped for the used one
