What components to build the lightest possible (but still reliable) AR pistol in 300BLK?
I'm going to guess:
Magnesium upper, lower, bolt&carrier. 10.5" carbin fiber barrel, no stock, but spectra sling. Poly 'iron' sights.
If these are lightest; what hand guards (or just leave the off?). Flattop, piccatinny rail?
What magazines/ammo are the lightest.
Any recommended alternatives?
