Used OPS 416 piston upper kit for Ar15's with 11.5 to 16 inches .875 max diameter barrel.
Kit is used, I sold my short barrel upper so I have no need for this kit. Worked great, has approximately 400 rounds on kit.
Comes with everything that come with kit including a new op-rod. My upper has a shorter than normal sight radius so I had to trim down the op-rod.
A new op-rod comes with the kit that is unaltered.
I do not have the pin for the op-rod
Also have the handgards that came with the kit that are not in the pict.
