20 450 bushmaster. lots of fun. - Radical Firearms Complete Upper Assembly .450 Bushmaster, 15in MHR, Single Ramp, Black, Box

My 3rd Radical Firearms upper. So far so good. BCG is a bit tight but should break in in a few more boxes of ammo. This IS a round you want to reload since finding factory ammo is kind of hit and miss. Recoil is pretty much a lot less than I was expecting. Read in most places that the .450 Bushmaster is like shooting a 20 ga. It feels a little more than a .300blk than a 20 ga. Brake isn't obnoxiously loud. Fit right on the lower without a problem. 1st box of ammo couldn't test the feeding from the mag since I had to single load it (range rules). Did have it short stroke a couple times and close instead of locking back. Something that should clear up after another box or two.

The handguard I'm not to crazy about. Has a metal mesh "feel" to it. Also the rail on the handguard where it meets the upper is a little fatter than the upper's rail and wouldn't let me slide the scope mount over it from the back. Had to slide it on from the front.
