Thread: What to do with my Omark ?

Na I've seen it before where people take brass and machine the rim smaller to suit the bolt face. Ends up looking funny a bit like the 450 bushmaster where the rim is much smaller than the base.no good for a controlled feed but ok for push feed or single shot.you have to turn each piece of brass but you can grind a cutter to the correct shape and its fast enough just dont throw your brass away!
