Amend2 polymer 6.5 grendel mags

[MattAmend2]

The first magazine will be just a 10 round capacity. After we tie up a couple other projects we will look at doing a higher capacity magazine. We also will be making a "minus 5" inhibitor that will also work in the 6.8 SPC version of this magazine we will release later this year. That will help out those who use their rifles for hunting in states that only allow a 5 round capacity.
