NEW!! Barrel Dimpling Jig for Low Profile Gas Block Use

Posted on April 2nd, 2015 by ar15news

I’ve built tons of AR-15 uppers and a good majority of them use Low Profile Gas Blocks with set screws and a few are pinned to the barrel. A couple of things I’ve learned with experience is that I always use Loctite on the set screws and whenever possible, I prefer to have the barrel dimpled for the set screw to seat in properly and really lock the gas block in place. It always amazes me when I spend good money on a barrel only to find that they didn’t take the time to dimple the barrel on the bottom side of the gas block seat and it happens more often than not.

The guys over at Parallax Tactical have found a way to make great use of their blemished Low Pro Gas Blocks by installing a Cone Point Set Screw that locks into the Gas Port of the barrel and a Hardened Steel Drill Bushing that allows you to use a simple hand drill and Cobalt 11/64th drill bit to dimple your barrels and in the exact right place every time.

These come as a complete kit, including the 11/64th Cobalt Drill Bit and is available for both .750 and .625 gas block journal diameters. The entire kit will sell for just $49.95 and can be used over and over again. Order one for yourself today at I’m going to!

Presenting a REAL gas block dimpling jig. (compare to BRD with no drill bushing, limited use. We had to buy three-four of them before we found it cheaper just to use our reject gas blocks.)

Comes with a hardened steel drill bushing, a cobalt 11/64th drill bit and a cone point #10-32 cone point set screw which positively locates the gas port for a perfectly lined up dimple directly beneath the gas port for optimum function and security for all low profile gas blocks.

Comes in 750 and 625 gas block journal sizes.

MSRP $49.95
