Since this takes 5.56 mags, would 300 Blackout work as well as long as you have a barrel chambered in 300 Blackout?

Question

James G. · Answer

Corey, this is correct and would be compatible with 300 BLK with the appropriate upper/Barrel Sir.

Michael W. · Answer

Corey, All components on this lower including bolt carrier group will handle 300 BLK rounds. Need to make sure the upper fits.
