I purchased a 9mm AR upper this past weekend, and after getting home realized I should have also picked up a buffer and spring as well. Looking around online, I see that buffers for 9mm can range anywhere from 4 oz to 8 oz in weight. I assume that the proper weight for the buffer depends on things like the weight of the bolt and the buffer spring itself. I am planning to use this on an MP 15 Sport lower, so I know I need a carbine length spring if I change that out.
Any recommendations/guidance on what weight buffer and spring to use? Would a carbine length spring for an AR-10 be OK, or do I need something heavier/lighter?
