After waiting for a couple months I finally got one of the new amend2 polymer 6.5 grendel AR magazines in the mail. I have been running metal ASC magazines on my MDT LSS XL AR chassis for some time now and the they work well but I have always felt that there was room for improvement. I noticed that theres a lot of wiggle room when I inserted the magazine, already a bad sign, I loaded the magazine to capacity (10 rounds) and some of the wiggle was gone but not all, once started working the bolt The first 4 rounds were FTF the rest of the rounds fed with no issues and quite smoothly which is what I was hoping for. Part of me is disappointed but then again these mags are designed for AR rifles and perhaps not bolt guns? Its a $18 magazine so I really don’t even want to go thru the inconvenience of a return. Maybe if I get rid of some of that movement in the well the issue can be fixed, any recommendations on how I can do that? Tape, Velcro? Any advice is really appreciated.
