My favorite ar buffer! - Aero Precision Enhanced Carbine Buffer Tube

My favorite buffer tube to use on AR rifles, I've used these tubes on at least 3 different builds. The ears on the bottom help lock the buffer tube in place and supports the buffer detent, as well as supports the back of the BCG providing a ramp as it goes into the tube. Definitely helps smoothen the action in my experience when used with a properly tuned rifle.
