The PRIMO Gas Blockâ¢ is a low profile billet machined, .625â 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.
Not compatible with Griffin's HEDP barrels. Compatible gas block can be found here.
