Custom delta m4 met reaper gen2 hpa engine

I am selling my custom built m4 with great pain. I had a lot of fun with it. It shoots so straight that I cannot shoot full auto with copperhead. It has a max hop up with a wolverine reaper gen 2 in bending 60 degrees. The upgraded barrel also comes with a magpull hand grip and the suppressor with tracer in the cable from tracer I have lost.
