I figure my only options here are MAYBE cut down a wrench to a small L and somehow get in there. Or else I don't know...Another muzzle device.

There's truly no happy medium setting you can set and forget it on?

Ball end Allen wrench looks like it might work.  If not, cutting one down will probably be your only option.

If he’s wanting to tune it with the can on for a dedicated suppressed setup, not really, only way to get it there is with live fire with the can mounted.

If he’s looking to tune it to a “happy medium” he could just tune it with no muzzle device mounted unsuppressed, then mount the muzzle device back up when he’s done.

One of the many reasons I prefer adjustable carriers over AGBs.

If you would consider a different gas block, OP, Strike Industries makes an adjustable unit that is adjusted via a collar on the rear.
You can access it through the hand guard.

Are you trying to tune it with your can installed?  If so, notching the muzzle device won’t help you.  If not, just tune it without the muzzle device installed and install it afterwards, negating the need to butcher your suppressor mount.

I don't have a can

Does tuning adjustable gas blocks need to be done if you are a reloader? Or is the range broad enough to where if it goes bang with one it will go bang with the other?

Really depends on how you tune it.  

Unless you’ve got a barrel with a massively oversized gas port or are tuning a gun to the ragged edge of reliability with lightweight reciprocating components for “gamer” purposes (which would mean sticking to one specific load for the rifle), I see little reason for an AGB on an unsuppressed gun in the first place.

What are you trying to accomplish with the AGB?  Why are you using that specific suppressor mount if you don’t have a suppressor to mount to it?

It's a midlength 11.5 and I just want reliable cycling

I really liked the way the brake looked

Maybe I should adjust it with bare muzzle to where it's reliable and then put the muzzle device on?

That’s a long gas system on a short barrel in the first place.  Most of the ones I’ve seen sold are advertised as being for use on dedicated suppressed guns.  What makes you think you needed an AGB?  If anything, I could see that gun being undergassed without a suppressor, not the other way around.

ETA:  Are you using a Faxon barrel?  I see they recommend an AGB with their barrel because the gas port has to be hogged out for reliable function.  They also specifically advertise the barrel as being perfect for use with suppressors.  Definitely wouldn’t be my choice for use 100% unsuppressed but I’d be interested to see how it works.

ETA 2:  If so, I’d either just swap out to a smaller diameter muzzle device or just notch it and move on with life.  Seems to be some mixed reports on unsuppressed functionality with lighter .223 pressure loads, but only way to know for sure is to test it out.  Tuning the block with the muzzle device removed should work as well.

Or you could take the gas adjustment screw out and grind some flats on the outside of it so you can get or make a small wrench to fit on it.

Oof. If anything your barrel will be undergassed, meaning the gas block would need to be opened anyway. Adding an adjustable gas block does you no favors here, especially without a suppressor.

That’s a Griffin Armament taper mount tactical comp.  That sloped surface at the rear is the surface that the taper mount locks onto.  You don’t want to mess that up, unless you never intend to use a GA suppressor, or other can that uses the GA taper mount via Plan A.

Not to change the subject, the muzzle device has a weld on it?  I am not familiar with GA, but what is the weld bead for?  Or am I looking at the picture wrong?

Get some weak ammo like PMC Bronze or Tula. Take the muzzle device off. Open the gas block all the way up. Load and fire a round. If the bolt locks back, close the block until it won't lock back. Then open it back up until it locks back again and then open the block a little more still. Put the muzzle device back on. Or, if you don't care about cycling weak ammo,  do this with whatever ammo you want it to cycle.

Use Rocksett and relatively low torque on the muzzle device. If you need  to remove it later, soak it in water for a few hours.

You'll probably wind up with the block open all the  way,  so access to the adjustment screw is likely to be a moot point anyway.

This is the correct answer.

It looks like you have enough gap there that a ball end Allen wrench should work just fine. Here's a photo illustrating what I mean:



Try this before grinding or removing anything.

If its the faxon barrel and Superlative Arms gas block ball end works, but barely.

You have almost no dwell distance. Unless the gas port is oversized, I don't think the gun will cycle, but I've never tried it myself.

People just don't get it. Adjustable gas blocks only give you less gas, they can't give you more gas.
People run adjustable gas blocks so they can tune the gun down to where it barely cycles for reduced recoil and so they can run exotic titanium LW bolt carriers.
Despite what some may say, I have absolutely never had over gassed cause a reliability problem.

Solution: ditch the adjustable gas block.

Not trying to be snarky here, but seriously... it’s an 11.5 middy... you need gas.
