Re: Semi-auto prairie dog gun quest
If it were my money to spend, I would build from scratch, If that isn't a realistic option for you, I would suggest the Rock River Arms A4 Varmint. If you want to save some weight, the Rock river arms Predator Pursuit is the same upper with a national match profile barrel. both come in lengths from 16 to 24 inches. My current set up is a 20 inch upper that is EXTREMELY accurate. Most AR15's from the major vendors will hold half moa accuracy in a varmint configuration.
.308 Howa 1500, varmint supreme. 24" .820 barrel, Roedale precision brake.
.223 Howa 1500, varmint supreme, 24" .820 barrel.
RRA 20" predator pursuite, Magpul PRS, ALG trigger,
