.458 SOCOM 10 Round Magazine

Caliber: .458 Socom

Capacity: 10 Rounds

Color: Black

Fits: AR-15 chambered in .458 SOCOM (or .50 Beowulf)

Material: USGI Aluminum magazine body, Stainless Steel Spring, Polymer Anti Tilt Follower

Follower: Calegalmags Green .458 follower

Laser engraved markings on the magazine body for identification:
.458 SOCOM
10 ROUNDS

These magazines are manufactured by Calegalmags as 10 round magazines with our proprietary .458 SOCOM (USGI) Green followers. The follower is purposefully designed to work with big bore rounds only. Smaller caliber ammunition is immediately ejected and can not be retained inside the magazine due to the follower design. These are not to be used for anything other than .458 SOCOM or similar sized big bore rounds such as the .50 Beowulf. Minor modification to the magazine body may be required for some end users due to feed ramp and/or projectile tolerances. 450 Bushmaster may require modification/bending the feed lips for proper retention by the end user due to the diameter.

Pretty good but not perfect

I bought two of these for my .458 SOCOM. Fit & finish is great and they hold the rounds well. Occasionally I'd get a FTF and it appeared that the cartridge was hanging up on the front metal lip of the magazine -- there were wear marks there on both magazines. I guess they eventually broke in because the FTFs stopped, but perhaps notching that front lip like some manufacturers do to add clearance for these fat cartridges would help.

Great for 50 beowulf as well!

So I bought a couple of these magazines for my 458 Socom. You have ran flawlessly for me which I'm obviously very happy about. I was at the range this last weekend and write out a brand-new 50 Beowulf I built and a couple magazines another manufacturer had given me. To my surprise the magazines would absolutely not feed the beowolf cartridges! I was super disappointed and then I remembered I had my 458 with me. I grabbed one of the magazines assuming it would work but I wasn't positive and I could not have been more pleased with the feeding on this magazine in my 50 Beowulf. It worked absolutely flawlessly. They were easy to load and 0 Jam UPS or malfunctions at all during firing. Oddly enough I got a reminder to review this product today just one day after using it so here I am and I definitely recommend these if you have a 458 or 450 Beowulf.
