Looking to sell my Echelon Comp build that has about 200 rounds through it. It has a Sharp Bros aluminum lower frame, Holosun SCS 320 enclosed optic, tlr 7 hl-x, 1 15 rd mag, 4 20 rd mags, Sharp Bros flared magwell, Tyrant aluminum mag release, and an owb t-Rex arms holster. I also have the original lower frame and back straps. I have close to $1850 invested into it. I will sell it without the optic for $1000. You can text me 512-466-259zero if interested.
