Most Helpful Positive Review These are running fine in my 450 Bushmaster.
I've bought a few of these now for my 450 Bushmaster. I'm running a Spikes lower with carbine collapsible stock and Spikes buffer. Upper is a Bear Creek Arsenal. No feed problems and fires and ejects right to the last round. I did not round off the front of the magazine as some have. Its still flat ...

Most Helpful Negative Review Buy something else
They jam...pure expensive junk...all four i bought, springs are to weak. After 5 or so rounds, they misfeed and jam. These were run in a CCMG...not a Franken AR...Pmags work a lot better even though they shouldn't.

458 socom Duramag

by Ian, from TN, United States Written on December 8, 2021
Bought one of these magazines. They were recommended for the 458 socom. It appears to be very well made. One thing it does not do well is work with the 458 socom. It doesn't line up with the feed ramp. It feeds the round directly into the receiver wall below the feed ramp. I even filed a half moon in it because it wasn't even clearing the front of the magazine. Now it works even worse total junk. I don't care what anybody says about pmags guess what they work

jams needs to be filed down to

by VE, Verified Owner from AL, United States Written on October 4, 2021
Haven’t shot it yet because I need to file down a half moon shape so that it can load the bullets. Failure to feed out the gate has me very upset. I bought these mags so I didn’t have to do any mods to it but you do. Using underwood ammo (extreme penetration & hollow points) tromix bolt on bear creek 458 upper.
