I think this is what you are asking for: comp.
I use the EGW gen 2 comp on both of my carbines.
Very happy with them.

Brownells sells jojos comp.
I bought a JoJo's comp from Brownells for my Colt MT6700, but I wasn't happy with the finish, or the quality of the machine work of the JoJo's comp.
I didn't think it was machined anywhere as nice as the EGW comp. I sent it back to Brownells for a refund.
Yep, it's nitpicky....I know it doesn't affect the performance of the comp, it's just a personal observation having both units in hand. I'm funny about little stuff like that.
