Don't buy this for your epc9 - Aero Precision EPC Buffer Kit

The Aero Precision EPC9 is a great gun but do not buy this buffer system for it. There's a good chance you will have an OOB with it. Reason: 308 springs should not be used with a AR9 and you should not use a solid buffer. The buffer included in this is just solid weight which increases bolt bounce. Don't buy this and go get yourself a carbine spring, carbine buffer tube, and a Maxim RDB buffer, you will thank me. I learned the hard way and my EPC 9 blew up in my face. Once I switched out these parts it ran flawlessly.
