Most Helpful Positive Review 6mm ARC mag
4 of 5 stars because they are so expensive and I've not done any long term testing; only about 300 rounds. I've tried close to all, if not all 6ARC mags available: all makes and sizes. I've found that several mags/brands work flawlessly for 12 rounds or less, but even then, it is an individual mag's personality. Geissele's (I now have three 20 rnd mags) are the only mags that I've had flawless running with! All three have worked perfectly for a collective 300 rounds.

No markings as pictured

Flat black mag, with no markings as pictured. Good quality mag that runs well, but I did expect to see the pictogram painted on as pictured.

What I received does not reflect what is pictured.

by TFavor, Verified Owner from GA, United States Written on February 11, 2026
What I received does not reflect the product pictured. It does not have Geissele markings on the body of the magazine. Also the product sheet that comes in the magazine ziplock is for MRGG (7.62, 6.5 creed,etc). Not sure what’s going on but it does have an IGC follower. Also, it took OP more than 5 months to get this to me. The estimated wait period was 2 months at time of purchase. If these are legitimate magazines they look different and you need to expect a very long wait. I’m also waiting 3 months on a trigger that is in stock everywhere… SSA-E

Best Magazine on the market

by Mike, Verified Owner from CA, United States Written on December 24, 2025
6mm ARC is becoming very popular, especially in the small frame AR. One of the problems in shoehorning a larger cartridge into a small frame AR is reliable feeding from the magazine. Geissele has overcome that problem. In my experience this is the best magazine for use in the 6ARC.
