Amend2 Polymer 6.5mm Grendel AR-15 Magazines — First Look

They said it couldn't be done! Amend2 Magazines introduces the first polymer 6.5mm Grendel/6mm ARC AR-15 magazine to hit the market!

Amend2 Polymer 6.5mm Grendel AR-15 Magazines — First Look
Amend2 Magazines has taken an interesting approach to tackling how to make a 6.5mm Grendel magazine out of polymer.

Without a doubt the 6.5mm Grendel is a great cartridge, but it does have one drawback, the magazines which feed it. The issue is the internal dimensions of the STANAG AR-15 magazine well specification. This dictates the maximum external dimensions of the magazine. The 6.5mm Grendel base diameter dictates the internal dimensions of the magazine. There is very little room between the two. Due to this it’s not possible to produce polymer 6.5mm Grendel magazines. There simply isn’t enough room. Well, there isn’t enough room without out of the box thinking.

Amend2 Magazines must have scratched their heads a bit on this problem before coming up with an interesting solution. Rather than a traditional polymer double-stack dual-feed design, Amend2 Magazines developed a unique double-stack single-feed polymer magazine. A 10-round design, it is made of an advanced glass-filled polymer. The patented design combines internal stabilizing ribs and a new 6.5 Grendel follower. Inside the magazine, rounds stack in a staggered pattern that narrows into a single stack at the top for optimal feeding. Because these magazines index rounds with the case wall instead of the case neck, they will also work with 6mm ARC. The result is lighter, easier to load, and is claimed to provide greater reliability than any other Grendel magazine on the market.

“Amend2’s 6.5mm Grendel magazine provides impeccable reliability,” said Matt Bellitti, Amend2 General Manager. “These mags have been designed from the inside out to prevent nose-diving, and to ensure stability and control for the wide 6.5mm Grendel cases.” The first of these new 6.5mm Grendel magazines will hold 10 rounds. Hopefully we will see higher capacity models in the near future. The magazines come in a variety of colors, including Black, Flat Dark Earth, OD Green and Gray and are available now.
