I typically just use an old magazine as a vice block but thought I'd give this a try. It's cheap and does the job but admittedly isn't as snug as using a magazine in the vice. It allows for a bit of side to side and front to back movement if the lower receiver when mounted in the vice.

Good Product

by BB, from GA, United States Written on January 31, 2020
Fits right in the magazine well. Allows for easy application of lower parts kits without having to worry about the lower moving around. Once the mag catch is installed, it clicks in just like a magazine.

works as advertised

by macdenny, Verified Owner from OK, United States Written on July 3, 2018
This is a basic AR15 vise block, it works as it should by securing the lower of your AR15 to your vise. The plastic seems like it is of decent quality for the price. If you are looking to do an AR build, an upper vise block with insert to align the gas tube is highly recommended.

Work Bench

by One Shot, from MS, United States Written on February 18, 2018
Great item to have for working on your rifle. Helps hold your lower part of your rifle in place while you work on it instead of blacks of wood that could ruin your lower. This lower vice block goes is a gteat addition to go with your upper vice.block and gas tube alignment tool. This is a must have.

Smaller than it should be

by B6, from TX, United States Written on February 9, 2018
Tried this on several different brands of lowers and it is very loose fitting on all of them, should serve the purpose for most situations , I bought a no mar block on eBay for $10 , it was extremely tight fit and had to shave it a little but is perfect now with very little to no play, would recommend that over the trinity force block
Pros:
  • fits
Cons:
  • To small
Best Used for:
  • Magwell holder
