Most Helpful Positive Review Exactly what I need
Perfect inexpensive product for the recreational tinkerer. Fits my AR receivers well and provides a convenient "third" hand. Would recommend for routine maintenance of your AR rifle so get a set for yourself.
Most Helpful Negative Review Cheap and worthless
While assembling a new upper, the upper receiver block from this kit broke while in the vice dropping my upper onto the concrete garage floor. Every promag product I have bought has been nothing but a disappointment.

Gets the job done

by Campa in Alaska, Verified Owner from AK, United States Written on January 29, 2025
I used this for barrel removal/installation and handguard swaps. I admit I am a little nervous about the receiver "plug" fit, but using a reasonable amount of vice force nothing appeared to move or get damaged so it appears to get the job done.

Stag Arms left hander here.

by M16ark69sr, Verified Owner from PA, United States Written on January 11, 2025
This will NOT work on Stag Arms upper receivers that are left handed ejection. Otherwise I would of given 5
Something should be stated that it is NOT compatible for left handed ejection.

Pro Mag AR-15 / M16 Upper And Lower Receiver Magazine Well Vise Block PM123A

by Mike, from FL, United States Written on July 12, 2021
This Pro Mag kit is exactly what you need to successfully build ARs. The items allow for sturdy retention during assembly, allowing for the use of two hands.
I’ve assembled several without this but wish that I would have purchased it sooner. It is a must for building , accessorizing, repair or cleaning.
Pros:
  • Great addition to your armorers toolkit
Cons:
  • None so far, after building two ARs
Best Used for:
  • Builds, accessorizing, repair and cleaning
Would recommend: Yes

Pros:
  • quaility
Cons:
  • None
Best Used for:
  • AR - 15

Absolute necessity

by Eric, Verified Owner from NY, United States Written on April 11, 2018
I've seen guys try to assemble with our these. There are 2 results: skinned knuckles while torquing and/or scratched receivers. Get a set, save time and money, and lend them to your friends! Theyre sturdy as heck, easy to stow in a tool box and a valuable assembly asset. If you decide building isnt for you, they look great on a coffee table as sculpture.
Pros:
  • Sturdy and essential
Cons:
  • None
Would recommend: Yes

Great product

by Frag magnet, from WI, United States Written on February 8, 2015
I bought this product for an AR build with an A2 style upper. The upper vice block worked flawlessly and the lower block makes life easy for not just building but cleaning and maintenance as well. Love it
