Just bought a new RRA 7 inch upper for my sbr. I have always ran a standard carbine buffer with the 10.5 I have. My questions is what is the best buffer for these short uppers, I have heard they are kinda picky and can have issues. It may run perfect, I have not shot it yet, may be kind of getting ahead of myself.
Is there anything else I should do to make it ultra reliable, or is that possible with a 7"? Thanks |
