Most Helpful Positive Review A great AR tool at a great price!
This AR Receiver vise block tool is used for aligning and clocking the buffer tube to the 6 o'clock position, perfectly every time! It is easy to use, and works. The block is well machined from aluminum block, with rounded corners and a nice anodized blue finish. There is a NcStar video, online that...

No More Crooked Buffer Tubes

by Gregory Henson, Verified Owner from TX, United States Written on June 5, 2026
This thing keeps your buffer tube straight while you torque it down. It would also hold the lower receiver to install the trigger, take down pins, safety and mag release. Like it a lot.

Vise lower receiver, vice block

by Alan Buchicchio, Verified Owner from FL, United States Written on May 22, 2026
I have seen previous videos on this, that some units had some issues on grip alignment hole issues. In my case I used it on a Faxon lower it was flawless easy to use and for the price very well worth it. The alignment with buffer tube and lower was perfect.

Looks as advertised

by Me, Verified Owner from HI, United States Written on April 27, 2026
I just got the vise, looks like it will do the job for buffer tube installation. I have not used it yet, 5 stars is for optics planet sending me the product quickly. Thanks. Since I haven't used it I can't recommend nor not recommend the vise. The review is forcing me to recommend or not before I can submit it so I'll say no and now you know why.
Pros:
  • Looks sturdy
Cons:
  • Unknown at this time
Best Used for:
  • buffer tube installation
Would recommend: No

Good Tool - Good Price

by Triangle 26, Verified Owner from CO, United States Written on March 27, 2026
Super useful tool. Not essential by any means, but very nice to have if you are going to use it. Makes proper alignment, torquing, and staking a breeze.

Product could be significantly improved by adding some type of retention for the loose screw and hex key which come with it - but I really can’t complain at this price point.

This thing is a champ. Installing/Removing buffers. Staking castle nuts. It does an awesome job. Takes a bit of time to set up but once it is it’s rock solid
