The Amend2 10-round 6.5 Grendel/6mm ARC magazine is a sturdy, reliable AR15/M4/M16 magazine made of an advanced polymer material. It is a light, durable and excellent alternative to the standard M4/M16 USGI aluminum/steel magazines. This magazine uses a patented internal and follower design to provide lighter weight, easier loading, and greater reliability than any other Grendel magazine on the market. This is accomplished by stagger stacking rounds towards the bottom of the magazine, and filtering them into a single only stack at the feed lips. 


  • 10-round magazine.
  • Sturdy, impact-resistant polymer with textured grip.
  • Anti-tilt follower.
  • Heavy-duty, non-memory, and non-corrosive stainless steel spring.
  • Made in the U.S.A.
  • Material able to cerakote.
  • Proprietary Grendel internal design.

    6.5 Grendel Mag

    Posted by Adam on 30th May 2023

    Bought one to try, i’ve had major issues with the metal mags in my Aero build. This mag feeds and cycles flawlessly. Will be tossing the metal mags and ordering more of these.

    6.5 Grendel Mag

    Posted by Jeffrey on 26th Apr 2023

    I bought two(2)of these mags to try on my 6mm ARC. They have performed well no issues regarding feeding or ejection, no stovepipes etc. Loaded some Grendel rounds and fed and functioned with out issue in an obviously completely different firearm, so I will use them for both calibers

    Do not buy

    Posted by William woods on 18th Apr 2023

    I bought 3 for my 6.5 grendel. I’ve tried 3 different brands of ammo and I can not get the mags to feed. I’d load the mags, put one in the magwell, release my bolt and no rounds will load. Rack my bcg, again they will not release a round to load into the rifle. Switched over to an E-Lander magazine and no problems. Wouldn’t waste your money on these, thankfully they were cheap so it’s not much of a loss

    Amend2 6.5 Grendel 10-Round Mag

    Posted by PistolGrip44 on 19th Sep 2022

    At first I could only load 9 rounds. I unloaded and reloaded it three times and was easily able to load it fully to 10-rounds. Another great mag from Amend2.

    6.5 Grendel 10 round magazine.

    Posted by Adam Collier on 15th Sep 2022

    I'm very happy with this magazine. I don't like metal mags all the time. So I'm thankful Amend2 makes a poly mag for the Grendel. It feeds great, and looks great.
