Description
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. The PRIMO’s pre-drilled hole helps locate the drilling operation on pre-dimpled barrels for fixture free installation.
