Review for
Vism Upper Receiver Block For Ar-15
I haven't used this specific model but purchased it after using the AR-10 version on a recent build. For the price, these are excellent and can handle tightening barrel nuts and muzzle devices. I would recommend getting some soft vice jaws to prevent marring the receiver block. Overall I am happy with the purchase.
Not Compatible with Aero Upper

This does not work with an Aero M5 upper receiver. The pic rail on the hand guard is about 1/8 inch lower than the pic rail on the upper receiver. Other than that the hand guard itself seems ok.
