Is it accurate to say 450 Bushmaster mags are fussy ?

I have 2 bolt guns and one AR, Never had a problem with any of them,

Are the 450 followers available anywhere online, or do they simply want to hammer you for the full cost of the 450 mags? I'd love to pick up a couple followers if they are available!
Thanks, and Regards,

The high price for the 450 specific mags is for the follower and the "walls" they put under the feedlips. So not the same as converting a 5.56 mag.

You can use a single shot follower for converting 5.56 mags, and probably be fine. The single shot follower is really only to keep the last round centered. You can also take a dremel and grind down a standard follower and usually be ok, too. I've done that to a couple mags and never have a problem with the last round. It's when the other rounds in the mag try double stacking and catch under on of the feed lips that might cause problems.

I just put a pair of generic 450 followers in a couple old GI 20 round mags. No filing or altering of the mags whatsoever. Both ran like clockwork on my newly built upper. I was pleased.

I have ebay and Quads followers in 20rnd. mil spec mags. All seem to work great thus far. Pmags just flat out wont work for .450bm. Tried it.
