Wired Mech box to the back
Put on Deans
Get rid of old 6 position stock

Put on RIS handle (doubles as a place to store extra mag - Will be switching that out for a spring loaded RIS handle with Bipod in it.
Kept M4 Cary handle but put a rail on it
awaiting Firefly medium hop up rubber

Put on a 3Pt sling this bitch is a heavy hump all day long.
