...the mags are just pmags that I have "cleaned" the front were the bullet tip slides out for a little more clearance when being slide into feed ramps; I started using these when I was having trouble getting 10 round grendel mags for bench shooting. The modified 20 round pmags seem to work reliably with only 8 rounds in them, 10 tops; If you load that mag with more than 8 or so, it becomes less pleasant... If you want more bullets at one time, the 6.5 grendel specific mags are needed; They function fine with the low volume and look pretty... If I duracoat a rifle, I usually use 6.5 specific mags and duracoat to match.
