The PRIMO Gas Block™ is a low profile billet machined, .750” 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 1/8” carbide drill bit and three ton press are recommended for pinning. Knurl grip cup pointed fasteners ensure a secure attachment to host barrel.
