I have a 5.56 build up for sale. Aero multi lower that I have upgraded to a single drop in sport trigger, new magpul handle and buttstock. Stag 18" stainless fluted upper barrel with a Samson Evolution Series handguard. Amazingly accurate and light for an 18" barrel with no issues. Was considering trading for a 1911 in 9mm or 45acp. Must complete bill of sale with DL or CHL for documentation. Comes with 20rd and 10rd mags including ammo as pictured. A few mags have ammo while additional ammo is new and sealed.
