Most Helpful Positive Review Great Magazine with a bonus follower
This magazine will hold 5 450 bushmaster rounds unless you take off the floor plate and remove the extra 5.56 follower that is flipped upside down on the bottom of the mag spring. Once you remove the included extra 5.56 follower (both the 450 and the 5.56 followers are anti tilt followers) this maga...

Most Helpful Negative Review Not Recommended for Glfa Upper
This is a well made and strong metal magazine. It said it is five rounds but I could only get (4) 450 Bushmaster rounds to work in this magazine. It will hold (5) rounds only if they are under 30 caliber which 450 Bushmaster are not. Also, I had problem with feeding in the GLFA 450 Bushmaster Upper ...

Did not receive the advertised item.

by Edward Willie, Verified Owner from NY, United States Written on April 26, 2019
I ordered this particular magazine because it is CLEARLY advertised as being stamped "450 Bushmaster". The magazine I actually received is not stamped at all. I shopped extensively for a magazine stamped "450 Bushmaster", I thought I found at a decent price. I was wrong.
I live in a state that requires permanently pinned magazines, and this magazine was for a caliber specific build. Unless I can find someone, rather quickly, doing a big bore AR-15 build, this item will be returned as incorrect.
Pros:
  • Solid, good quality
Cons:
  • not shipped as advertised
Would recommend: No

Not a single issue

by Blake, Verified Owner from AA, United States Written on April 20, 2019
I got this to use after searching for a 450 mag solution. I found it with this one. This magazine works perfectly for me. No need for any modifications and fed just fine. I would definitely buy more of these.

Mags had an extra 223 follow inside that needs removed before use

by Slayinbucks419, from OH, United States Written on February 21, 2019
First loaded mags and wouldn't lock into lower with bolt closed. Gun jammed often. Upon further inspection the mags had a 223 follower under the spring which caused to much tension removed the 223 follower and mags worked flawlessly

450 bushmaster magazine

by Keb, Verified Owner from MI, United States Written on October 4, 2018
Excellent mags for the price. No problems feeding my ar 450. Will buy more. Mags did not seat fully on a closed bolt at first. No problems now after a little wear in time. Mags drop free upon release. Holds bolt open on last shot.

Only 450 mag that works correctly

by Big buck, from MI, United States Written on September 18, 2018
This is the only 4 shot mag that works correctly. I’ve tried several others but the either stove pipe or fail to feed the big rounds. Go with the factory original to give you peace of mind. Instead of having to modify a magazine just get the original bushmaster and you’ll be trouble free
Pros:
  • Works great
Cons:
  • None
Best Used for:
  • hunting
