Smart-Fit® Vise Block Sleeve For AR10*
SLEEVE FOR AR10 SLIDES OVER SMART-FIT AR15 VISE BLOCK
The Smart-Fit Vise Block Sleeve for AR10 is an innovative product that allows you to work on large frame AR’s with precise fit and zero wobble. It is designed to slide over the existing Real Avid Smart-Fit AR15 Vise Block and eliminates any wiggle or movement while working on the firearm. The sleeve can be used with an inverted lower receiver to work on pistol grips or allow easy access to the underside of your AR. It is a must-have tool for securing an AR when swapping trigger groups, servicing the lower receiver, installing grips and buffer tubes, or easily cleaning the barrel bore.

Definitely would not recommend. You’re going to pay about $35 or more by the time this ships and the quality is definitely not what I expected. Fits Well on the adapter but does not fit well at all in the magazine well. There was a lot of slop and play, making the gun unstable in the vice. You can get a solid block for about $10 on Amazon with free shipping which is what I wish I would have done. I love most of my avid products, but this is definitely not the quality I was expecting especially for the price. It’s a 5$ part at most. They should just make a standard block like they do for the AR 15 without needing an adapter because that one is perfect.
Great addition to the block super snug fit!
Great tool. Now you can work with ar10
Had to modify to get it to work in an actual Armalite lower
Fits perfectly. Tighten up very easily and holds the gun very securely.
