Ap enhanced buffer tube - Aero Precision Enhanced Carbine Buffer Tube

I've used this buffer tube a few times on some previous Aero builds and it's a great buffer tube. It has carrier support extensions to reduce carrier tilt and to support the buffer retainer pin. It has position guide drain holes for drainage and air escape. It has a ramped tube design for easier stock installation. It also has proper thread depth to prevent stocks from getting trapped and is machined from 7075-T6 aluminum with a melonite finish to provide enhanced reliability, security and simplicity over traditional mil-spec buffer tube. Lots of great features and I like using it on my M4E1 builds. This one I just bought is for a M4E1 pro build that I am doing. I highly recommend it.
