What is your longest range build? As I’m a big AR platform guy, I have two.
First up, a 6.5 Grendal. 20" barrel, ATIoutdoors handguard, stock, and grip, 80% lower, and a 3.5# drop in trigger from velocity triggers.
Next is a .50BMG, 30" barrel upper from McCutchen firearms, mag fed bolt action. Using a 80% single shot lower from Hellfire armory, LUTH-AR fixed length stock, and a ADCO BM330 scope from ADCOsales.
