Ar-15 flat-top riser - NcSTAR AR-15 Flat-Top Riser-Mount Standard Weaver Base

I use it on my S&W MP15-22LR ("Kick Brass"). It is perfect for the low profile scope I use. It gets my head up into a more comfortable position to look thru scope instead of smashing my cheek into the stock. I am very pleased with it. Good price and quick delivery. Simple to mount. Looks good, too.
Pros: Does what is expected; easy to use
Cons: none
