Thought about sending this off and getting it chopped and dimpled but too many projects. They are a tank of an upper and not a lot to say, this is the standard sr5.56 upper not the c model or take down. I believe the brake was one with the barrel and couldn’t be unscrewed on those. This one you can so run whatever you want or send it off to have cut, it has a simple 4 setting gas setting so it will shoot great with a can or low powered steel ammo. Eats whatever you feed it, solid upper and built when Ruger thought they were going to compete for gov contracts and the piston hype error. Uppers are tough to find on their own as I haven’t seen any online. It does have the Troy rails/ panels it’s a full upper so it will come with the BCG and a laser etched (We The People) charging handle. I think it’s priced right for a solid piston upper that will eat whatever you feed it but if you have an offer let me know. We can talk about adding a set of irons but currently it will not come with them or the grip . I will entertain all trades can add to if item is of more value.
