Gas Block Pinning Jigs for SLR Non Adjustable Gas Blocks

thingiverse

These are gas block drilling jigs for two sizes of non adjustable gas blocks made by SLR The GB7 Pin Micro Block (https://slrrifleworks.com/gb7-pin-micro-gas-block), and the GB6 Micro with .450" Spacing (https://slrrifleworks.com/gb6-micro-gas-block-450-spacing) The hole for the drill bit is oversized, with an angled window cut into it. This is to allow you to check and recheck proper positioning for your setup within your vise before turning on the press to begin drilling. Use a bubble level on top of this jig in your vise to make sure everything is level after tightening Make sure that you support the bottom of this jig with a piece of steel, with a hole cut out for the bit to go through. Don't rely on just a 3d printed part to hold as you push down with the drill bit, there's a lot of force being applied, especially at the end when clearing through the other side Before drilling, I dimpled my barrels for set screws, to help ensure that everything stayed in place I used a #31 Cobalt drill bit in a press, then a 2/0 taper reamer by hand
