Nice magazines seats easily and firm.
I expect these SS AR-15 Mags will work as well as all the others in my 300 BO rifle. Excellent magazines.
I have the duramags i use in an AR 15 and love their size and toughness. I ordered them for the 300 Hamr, which takes the same mag as the 300 Blk. I could only get six rounds into the mag before the tips pushed in causing the rounds to crowd in and jam. Same problem in a std AR 15 mag. The Blk takes a mag with wider internal channel to allow for the 30 cal rounds. Have you tried loading Blk into these?
Nice finish. Operate flawlessly. 100% reliability!
