Rifle is a 1:8 AR-15 with 18\” barrel and rifle length gas system. Springco blue spring and JP bolt are the only modifications. 3x microprism optic was used for all shooting. Shots were from a bench, but without a formal benchrest or sandbags of any sort. I had a carpet-covered wood block on the front and nothing on the back.
Powder: CFE-223 @ 25.2 grains
OAL: 2.255\”
Primers: Win #41
Brass: LC and RP were both used.
Without a real rest or even sand bags (as noted above), groups were 1.5\” at 100 yards. That\’s with a variable wind of 5-10 mph from L to R. I have no doubt less than 1\” was possible.
