Great product, just confirm fitment to your rifle
It worked for what I needed it for. The upper vice block didn't really fit my upper(wouldn't close all the way) but it did hold enough to do what I needed. The lower worked flawless as its just like a mag going in. If you're wanting to work on your ARs I highly suggest them. Makes it a whole lot easier.

Ar vice block
Worked as designed, would order again but will never need another one ???? decent construction and worked well. it held the upper receiver while i struggled to remove the a2 style barre nut where ended up freezing and then using a large pipe wrench since the nut was installed with out anti seize. Use the lower mag block when cleaning my gun.

ProMag AR15/M16 Upper & Lower Vise Block
This was FANTASTIC!!! It grabbed even the take down loop on the front and really held tight. This item made getting the factory Delta Ring barrel nut off easy!

Works great with modification
Bought this set to build my first AR-15 and was impressed until I tried to clamp the jaw over my upper receiver and could not get it closed. Modified the clamp by grinding out material in order to fit receiver, then it worked great. Helps hold your rifle securely for tightening barrel nut, muzzle device, etc. Doesn't mark up parts or remove finish. Pros: Durable Cons: Clamp requires modification for some uppers
