Help adjusting gas block

[One1Bravo]

So the hex key Compass Lake sent to adjust my gas block is way too short to use. As you can see, it sits inside the handguard. I tried going in from one of the M-Lok slots but the key is so tiny it just flexes without enough room to actually turn the screw. I ordered two sets of 9 inch T handle keys down to 2mm and I still don't have one small enough to fit. Is there a way to do this without having to remove my handguard? Need to get this thing adjusted so I can shoot with my supressor.

What size allen is it? McMaster Carr sells individuals and lists the handle lengths, so if you know those two dimensions you should be able to find something to fit.

Get the Allen as a hex bit then use a 1/4 extension and little ratchet.. or get a barrel and gas tube with a +2 gas length.

Eklind definitely makes one long enough. Find out what size you need. Should tell you in the manual. What gas block is it?

Whatever adjustable gas block Compass Lake had on hand when they built my rifle. Paperwork made no mention of it and I have no idea what size this key is. Whats the best way to measure it? I have calipers and a ball micrometer.

Calipers or a ball micrometer.

Or, go down to the home depot hardware aisle, and stick it in different bolts until you find the size that fits best. It's the modern day man's cinderella story.

Compass lake is a good company from my observations. Give them a ring and I bet they can tell you what size you need. If it’s like the cheapest gas block I can find then the Allen to lock adjustment after set is on the side and a different size. Gotta adjust before you need to worry about locking though.

Duh. Brain fart.. just use your calipers to measure the Allen that fits it. Do in metric and standard to see which size it’s closest too.

Looks like it's a 1/16.

If you can’t find a store that has any sets with a bit that small then find out we’re the nearest Mac, snap on, or Cornwell truck is. You can get the local guys # at a friendly mechanic shop. Actually a friendly mechanic would probably have what you need. If you can’t find and don’t want to wait for the right tool then go to a fab shop and pay a welder to extend your Allen

Amazon sells Bondhus hex drivers dirt cheap. All different lengths. Prob can have one in 2 days with Prime

Take a torch to that wrench and remove the bend...or just cut/grind the elbow down a bit.

 

[supercorndogs]

Probably either 1/8" or 3mm.

Way smaller. I have a 2mm that doesn't fit. Its 1/16.

Honestly it’s probably easier to just remove the hand guard depending what you have

Remove
Tune
Reinstall

I cut the Allen wrench off and drilled a hole in a wooden dial rod and made one to reach the GB’s on my AR’s...
....
Used 30 minute Epoxy to hold in place...

Tried that route. The first bit I tried immediately snapped off the tip, sent them back. AGBs need to be freed up every few hundred rounds at least, or they'll turn into non-adjustable gas blocks. SLR makes long-reach allen screwdrivers.

Never snapped a Bondhus off in any of my SLR, Superlative, or Seekins gas blocks. Did you find one that works for you yet? Buy a set of snap on T handles I guess

I know you were addressing Slevon but my issue is the length. I ordered a bunch of stuff from McMaster Carr to see if I can find anything that will work. 1/16 is small as shit and there isn't a lot out there.

Bondhus hex drivers, as mentioned above. for my SLR adj gas blocks, I have several in varying lengths from 2" bit length up to about 8" I think. From Amazon.

Thanks! Found an 11" driver. I got that bitch now.

You need to stop that simpleton thinking. It makes way too much sense and saves money by preventing the purchase of more tools, etc.

You're outta control.
