I love how the Gas Block is pre-drilled for pinning. Great idea.

Description


The PRIMO Gas Block (http://www.griffinarmament.com/PRIMO-Gas-Block-750-416R-crucible-alloy-p/gapgb.htm)™ 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.
