Exactly what I was looking for
April 8, 2022
: JEH from Eagle River, AK
This is one of the only gas block jigs that will allow you use it with the gas block already installed on the barrel, such as a barrel you’d want to pre-install the gas block on for a pinned and welded muzzle device...and MAS Defense had one of the best prices I could find on this one.

Little pricey for what it is, but needed. Loses one star for value.

Gas block roll pin installation jig
December 1, 2021
: Todd Wilkinson from Ohatchee, AL United States
I can't say the jig works good... Yet. My parts will arrive in a few days for my 300 blackout pistol build. But I can comment on the quality of the jig, which is nice. I'm for sure it will beat the crap out of installing that tiny roll pin while keeping the holes lined up while holding the roll pin with a pair of tweezers. The only negative aspect I can think of, is that it went on sale for $3.00 cheaper the day after I ordered it.
MAS defense has good customer service and shipping was super fast.

: from ,
This tool made the installation of the gas block roll pin extremely quick and easy, would recommend to anyone that has tried to install one without this tool.

Gas block roll pin install fixture
April 16, 2021
: Steve E from Catawba, NC United States
Works like a charm! Beats chasing pins around on the floor or trying to use a magnet to find them in the grass. Wish I had known about this gadget years ago! If you are going to build ar's it is a must have!
