I've been lurking here a while and learning. I took what I learned and finally built something.
Rifle is a billet upper and lower with 11" barrel and 3 position gas block from TP555 and my YHM SS Phantom QD .30 suppressor. I threw on a Weaver 1-3X variable for load development.
Finally got this group at 50 yards. 10.9gr H4198 208gr Hornady A-max, 1052 fps average for 10 rounds with a called flyer. I managed a group of 1.5" at 100 yards (pic was bad). Not bad considering I was shooting from a card table with one of those triangular plastic rests and no rear support, and the crosshair was only slightly larger than the dot.
Hopefully with the 12X scope I have mounted and a good rest I can get well under MOA.
This is a great forum and everything I learned here made this a relatively easy project.
