Has anyone had any success making their own adjustable gas block from a lo profile GB (or any other type of GB for that matter)?

I'm ready to give it a try and would like to get some ideas on how others have approached it.

Made out of G5 titanium

That looks terrific.

I made one also from titanium but I went with my own two piece design so I could change if I had to on a 14.5" barrel with pin comp.

You both definitely have great fabrication skills. Thanks for posting up the pics.

What size screws did you both end up using? M4-M6?

I was thinking about a forward facing adjustment screw as well. Probably use a allen head cap screw with a jamb nut to keep it simple.

Is the adjustment screw readily available, or are they custom made?

The socket head cap screw is just a standard screw. The set screw on the side has a spring and ball built into it. I put slots in the SHCS so it clicks every quarter turn.

No, the SLR one is made for them.

The gas block being converted is very contoured and doesn't have much material between the gas tube and barrel so I went from the side to hit the gas channel in the block. It looks like only 4 threads before it hits the channel. Hope it's enough. Have to pick up a M4 screw and from Ace tomorrow. .

I love to see the talent some people have and their dedication to fit and finish...  


Well back to my little project... it ain't best prettiest thing I've done, but it ain't the ugliest either....

The screw goes all the way across the gas channel so it should work saving me about $40+ over getting a cheap adjustable. Won't be able to see it under the rail anyway...
This is screwed all the way in. Used a little alumablack to blacken the zinc nut and washer. M4 screw






Looks like I lucked out and it will be accessible without removing the rail, so long as the lock nut is reachable with a small box end wrench from the front. It doesn't need to be very tight, just enough to keep the screw from walking I suspect.
