Simply put, you’ve just found your new favorite mag for your 6.5 Grendel and 6mm ARC firearms.
Best Performing Mag on the Market
Extremely Compact
Full Two Stage, T360 Coating
With the 6.5 Grendel DURAMAG SS™ line of magazines, feeding your 6.5 /6ARC / 22ARC has never been easier. These specialty cartridges demand a proprietary magazine and the DURAMAG SS™ delivers one that outperforms the competition while remaining affordable. These magazines offer fantastic internal room for long cartridge loads, so you can get the most from this caliber. These DURAMAG SS™ magazines also boast extremely easy loading and feeding first-to-last round.
Available in 5rd, 10rd, 15rd, 10rd, and 26rd.
LipLock technology keeps rounds secured and in proper alignment
Advanced Geometry Follower™ remains level for consistent feeding
T-360 total coating technology covers the entire magazine, inside and out
EverFlex™ anti-fatigue spring technology for long life and ultimate reliability
Post & Hole™ adds strength, durability and robotically welded precision
I spoke with Justus on the phone and he was able to help me out by pulling an order and shipping it next day air for me so that I had these mags for a rifle class I took. Amazing customer service!!
The mags themselves worked very well in my Geissele GFR, only had one jam out of about 2-300 rounds (which was entirely my fault- keep your bcg’s lubed fellas). The only downside to not using Geissele’s proprietary mags is that the bolt wouldn’t lock bag after last round. But that’s a pretty small thing to note. Aside from that the mags worked and functioned properly. Will definitely be getting more of these in the future. 10/10 would recommend.

I got a request to review this product but I still haven't gotten it. I keep hoping the USPS will deliver. Maybe this week. I cant give 5 stars for something i haven't gotten but I had to give a star rating.

Solid mag
Posted by Andrew on 4th Feb 2026
Zero failure to feed issues so far 100rds. Only gripe is base plate for FDE is black but I value reliability over cosmetics so if some one looks at the bottom and I care enough I can rattle can it. But I will buy a couple more.
My setup is mass defense upper, Wilson combat 18” barrel and bolt, lantac muzzle brake, jp silent capture spring h1, trigger tech. PRS stock.

I can not rate this product because I did not receive this product. You sent me a 350 Legend mag instead of the 22 ARC mag that I ordered. Sloppy!

5 round magazine for Ruger American 6ARC
Posted by Okanagan on 6th Nov 2025
Disappointed in the size. I thought a five round mag would be shorter than the ten round but it is the same awkward length that hangs way down from the Gen II Ruger American. The web picture needs clear info that this is the same length as a ten round magazine.
