Description

The PRIMO Gas Block™ is a low profile billet machined, .625” 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.

Not compatible with Griffin's HEDP barrels. Compatible gas block can be found here.

    Perfect fit, finish, everything well machined. Everything in photo was included in very nice packaging. Installed on a Faxon gunner, aligned set screws, then drilled for pin with 1/8 carbide bit. Very happy with purchase. Material and finish are identical to the Faxon barrel which was a plus, pin hole is pre drilled. very pleased.
