My Son and I did Fathers Day yesterday. We went down to Casa Grande and sighted in a couple of our latest builds. Him shooting, I was spotting for him. This is a .308 Mega Monolithic receiver set, Ranier 20" match barrel, Lantac BCG, Timney trigger, TA-55 Acog.
Once zeroed at 200yds, had no problem tagging the steel plate up on the hill at 650yds.
This is another .308 Mega Monolithic receiver set, 12" Noveske barrel, Noveske BCG, Milspec trigger, topped with Eotech. Damn thing is LOUD.
