Battle Bloc

This 3D printed chamber flag will make your AR easily identifiable as a clear weapon while doing any type of competition shooting or needing to run from stage to stage. Instead of fumbling around with a small chamber flag, racking the bolt back at each stage, or locking the bolt to the rear with the possibility of the bolt catch/release being hit and letting the bolt forward; this 20rd faux GI mag will ensure you have a clear weapon and make it easy to show at every stage. We designed this to ensure that it will fit in both stamped and billet lowers.
