I have a super nice Aero Precision AR15 chambered in .50 caliber (Beowulf 12.7mmx42mm). Upper is an Aero Precision 18" (stainless barrel) "XL" AR15. Lower is a premium PSA lower AR15 reciever. Has a huge "tanker style" muzzle brake specifically made for a .50 caliber cartridge. Has a Midwest Industries 16" key model rail with full length picatiny rail on top. I have one "big bore" AR15 magazine to go with the rifle (takes standard AR15 5.56 magazines too). Has an upgraded single stage trigger, H2 buffer and upgraded buffer spring, and raptor charging handle. I also have a really nice LNIB Aimpoint P.R.O rifle optic that will go with it, it has been mounted on the rifle but was put back in the box shortly after deciding to go with a variable zoom scope instead. The optic has never been on a rifle while being fired. The rifle has been professionally painted (not rattle canned, but it also isn't cerakoted), optic has not. Will come with the following: 1 magazine, about 120 rds of quality ammo, and the Aimpoint rifle optic. Mostly looking for trades but willing to sell for the right price.
