A Reliable Magazine to Feed Your .450 Bushmaster “Thumper”
The .450 Bushmaster is a popular hunting cartridge, but a good magazine can be hard to come by. With the straight-wall design, supporting each round for reliable feeding can be a challenge. Luckily, ASC has it all figured out with this 5-round magazine for your “Thumper” AR-15. Featuring supporting ribs to keep cartridges in place, and preventing malfunctions, this magazine is a great choice to feed your big-bore hunting rifle.

Designed to Prevent Double-Feeds
While originally intended to fit a standard AR15 magazine, improper geometry and follower design can lead feeding issues and rifle malfunctions for .450 Bushmaster. By creating a proprietary internal bracing system and laser-welding it into a 410 stainless-steel body, this magazine prevents rounds from getting misaligned and prevents double-feeds.
The enhanced system of this AR-15 magazine also ensures reliability over thousands of rounds, not just the first shots at the range.
