After buliding up my lower, I've been trying to decide between M4 feed ramps or normal feed ramps. The rifle is going to be a 16" midlength. I've heard that M4 feed ramps help when shooting SP ammo.
I'd like some first-hand reports from people who have used SP ammo with and without M4 feed ramp cuts. How is feed reliability?
