Built this a while back and it gets no use and I could use some Christmas money. Less than 40 rounds through it. Comes with the Magpul D50 50 round drum mag which has had only 20 rounds through it. The upper was complete from Aero with an 18″ stainless barrel. I replaced the bolt with a Lantac Enhanced M-spec full auto rated bolt. Has the Aero ambi charging handle. Scope is a Vortex Strike Eagle 4×24 power with the EBR4 MOA reticle on a Leopold cantilever mount. It has a cheaper AR Stoner tanker style muzzle brake that works pretty well. It has a Magpul bipod in fde. It has a Geiselle Super 42 braided buffer spring with an H2 buffer weight in a Geiselle anodized buffer tube. Magpul stock in od green with a rubberized Hogue grip in od green. Multicam B5 systems vertical grip. I built the lower from a stripped receiver and put in a LaRue tactical 2 stage flat faced trigger to try theirs though I found I still like Geiselles more. I secured that with Wilson Combat anti walk pins. It has an Odin Works extended mag release and an extended bolt catch. Had too much time on my hands one winter and rattlecanned it because I hate the look of black rifles. The only issue with this thing is the rear takedown pin needs replaced. I wss adjusting the play in the receivers and got it too tight and had to use a punch to remove the takedown pin and I tapped too hard and it broke through the stop point on the other end of the takedown pin which was probably faulty from the factory. Still functions and a cheap fix. She runs like a dream.
