Love the tube! - Aero Precision Enhanced Carbine Buffer Kit

This is my all-time favorite buffer tube. The enhanced added extension of the threaded portion helps retain the retainer pin and makes it much more secure. Their buffer and spring work very well together. The only reason I gave it a 4 start is I never use the standard endplate. I bought the combined kit to get the other three parts and then purchase a ratcheting endplate and lockring. Hands down though on the buffer tube, best there is.
