I have a PSA upper on the way. They are back in stock as of this post.

Been looking at ammo options (reloading) and in looking around for Supersonic use many options are out there. I have some 110 V-Max bullets on the way but they are very pricey. I have about 400 125G spitzers that I bought as AK bullets but are .308. Also have .310 bullets and many have reported good results using them as is and not resizing them.
In poking around I also have 1000 of the M-160 108Gr frangibles that I bought for nothing. So some testing is in order.[Flower]
