Here we go again right?
Much has already been said on this forum regarding 450 Bushmaster magazine issues. The list of problems is almost endless, as well as the multitude of Band-Aid solutions. A thorough search might produce a days’ worth of reading. For those looking for a reliable 5 shot hunting magazine, the problems have all been critically addressed and eliminated by BartZ Mfg. BartZ presently has 1500 new 450B magazines in circulation and has not had one complaint. This thread isn’t meant to sell magazines as they are selling fine. I’m taking a moment to let the brotherhood here know you don’t need to endure the frustrations any longer.
For those of you looking for a reliable high capacity 450B magazines, I am afraid you will continue to be frustrated. By virtue of the 450B’s straight case walls you will not be able to get reliable feeding from a banana shape magazine. Magazines bend in proportion to the case wall taper of the round they are designed for. 5.56 mags bend a little because they have a gentle taper. 7.62x39 mags bend a lot because they have a sharper taper. 450B mags are straight because they do not have a taper. A high capacity 450B magazine just isn’t in the geometry.
A word about ASC and Stoner. ASC builds magazines and Stoner sells magazines. ASC builds magazines to customer specifications. It isn’t fair to hold ASC liable for a customer’s weak requirements. When a customer wants to put mags “on sale” as lost leader items to hook you into shopping on their site what do you think they specify when ordering from ASC? ASC builds Bushmaster brand magazines too and we all know what problems we have had over the years with those magazines. ASC builds BartZ Mfg magazines on an entirely different production line and we have never had a single problem with them but I can tell you we have different requirements than the other guys. ASC builds some of the best AR magazines in the world for those companies that specify it. Furthermore, our ASC made 5.56 magazines accept 2.280-2.300” OAL rounds. You don’t get that from the other guys either.
Short rant… it stupefies me how guys can spend upwards of $2k on a rifle/optic combination that they expect to shoot sub MOA and then refuse to pay for two good magazines to feed it…rant over.
Hope this was helpful,
