The upper receiver is an A4 flat-top upper, which accepts most common sights and scopes.

But don’t worry, we have plenty of options available!\u00a0This upper receiver weighs in at approximately 3.5 pounds, so it’s not too heavy or too light. And of course, it’s made in the USA so you can rest assured that it’s built to last.
