This is a custom AR upper assembly built by Lee Mosher of Colorado. It is chambered in 20 Tactical. It is in very good condition. It has around 150-200 rounds down the barrel. Very accurate gun (Lee Mosher guarantees his uppers to shoot 1/2" at 100 yds). 26" Jeff Lawrence cut rifle barrel. 1:12 Twist. Les Baer bolt carrier. Feeds very good. It comes with Redding dies (form die, bushing size die, and competition seater die) and Lapua 20 Tac brass (not sure of the quantity, will have to check. approx. 100 pcs I believe). When I purchased this from Lee they were selling for $1400 and that was without dies/brass. I'll take $900 for it all. I'm sure I even have some berger's that I throw in too. Only reason I'm selling is to fund new project. Please email me if you are interested and want pictures. Thanks [email protected]
