Description

The PRIMO Gas Blockâ¢ is a low profile billet machined, .750â ID block, made from nitrided 416R crucible alloy steel. The block has two provisions for mounting, set screws and / or pinning. The included splined pin allows qualified gunsmiths and experienced builders the option of having a military style secured gas block. A 1/8â carbide drill bit and three ton press are recommended for pinning. Knurl grip cup pointed fasteners ensure a secure attachment to host barrel. The PRIMO's pre-drilled hole helps locate the drilling operation on pre-dimpled barrels for fixture free installation.

Griffin makes great products. That was the reason behind my choice in this gas block. I’ve purchased other products made by Griffin that have held up. I will continue to be customer.

Fixed My Problem

Published by Brandon on 8th May 2020

I am what many would consider a poor, so while building my AR10 I used a PSA upper. The adjustable gas block didn't work and I had constant cycling issues. Griffin Armament being less than 30 miles away from my house had the best quality part and it fixed my problem. Very pleased to say that I no longer have issues with my rifle.
