BRT MicroPin Gas Block

BRT MicroPin Gas Block™

 

Description

The Black River Tactical MicroPin Gas Block is designed to fit under most available free float rails and fits all AR15/M4 barrels with a .750" nominal diameter gas block journal.

Pinning of the gas block is a must for professional end users who demand the ultimate reliability from their carbines.

In fact, the Mil-spec requires pinning on Front Site Bases.
 
Most low profile gas blocks are designed to be secured with just two small set screws.
  
Unfortunately, those gas blocks can come loose from the heat and impact of heavy firing schedules and rough handling.
 

The Black River Tactical MicroPin Gas Block is designed to be easily pinned to the barrel in addition to set screw mounting, for a maintenance free, reliable solution.

It features a flat, center spotted face that allows for easy drilling and installation of the coil pin.

To install, just secure the assembled barrel and gas block in a drill press vice and drill through, using the center spot as a guide.

The stainless steel coil pin is then easily driven in and results in a permanent solid lock up.

The block may also be used with solid dowel pins and taper pins.

We offer our Pinning Kit separately for those who wish to install a solid dowel pin.

 

All bores are machined to very tight Mil-Spec tolerances to ensure precise fits on both the barrel journal and gas tube.

This maximizes gas flow and allows top gas system performance.

The .7515" Oversized Gas Block is identical to our standard gas block, except the bore is slightly larger to accomodate barrels that have been Cerakoted or barrels that have oversized, tight fitting gas block journals.
 
Coating of barrels increases the diameter slightly and generally makes assembly of standard gas blocks very difficult.

 

All Black River Tactial products are 100% designed and produced in the USA!
