Hey guys, I'm trying to take advantage of some holiday pricing and am looking for the proper buffer system for a .300 blackout pistol. This will be my first build and I'm just now starting to acquire some of the parts. I am purchasing a complete lower minus the buffer and stock. I do not have any upper components yet, but my plan is to go with somewhere around a 9" barrel. I do hope to purchase a suppressor but if I'm being honest with myself that likely won't happen anytime soon. The longterm goal would be a home defense rifle. Can ya'll drop some buffer knowledge on me? Thanks!
