450 Bushmaster Lancer mag

Bigboremag20 Oct, 2021Other

Big bore mag was established in 2016 to fill a need for the big bore market. Today we injection mold our followers using aluminum tooling. Our capacity limiters are 5? long and can be cut down to size. These fit mil-spec magazines. This adapter converts both our big bore mil-spec and hex follower to 223/300aac blackout. The adapter installs as easy as sliding it around.
