Does not hold ten rounds, 50/50 fittment - Ammunition Storage Components AR-15 6.5 Grendel Stainless Steel 10 Round Rifle Magazine

These mags do not hold ten rounds of ammo without a lot of force and if you do cram the tenth round in, it will not lock into lower. The quality of the mags very about 50/50 half of the mags I bought do not fit into any lower so far I have tried four different lowers with same results. So half my brand new mags had to go in the trash. Might as well pay a few dollars more and get good consistent quality from the Duramags especially if running on a 22 ARC.
That said the mags look nice and the ones that fit are great other than they should be listed as 9 round mags in my opinion. I would like to see this company fix their quality in the welds and I think that will help get a more consistent functional product.
