theres 2 set screws. One in the front I could access with a long allen wrench.Why not just use a long Allen wrench (or whatever) to reach the gas block?
yeah, its too far tucked in behind the handguard "rib".Have you tried a ball end Allen?
I have always let the Dremel do the talking.
Might be worth removing that little piece blocking access to the GB.
I promise.It's nothing to take off the handgaurd. Just those two screws and pull it off. Don't mar up your forend.
So my adjustable had two screws as well. One was the actual gas adjustment and the other was a set screw to hold the adjustment screw. Bottom line you will need to loosen and tighten both for any adjustments.so I need to set up the adjustable gas block but the mlok handguard is in the way of the set screw. I've never removed a handguard before so my question is how and does it affect the barrel install?
do all I need to do is remove these two screws and slide it off?

Was this a factory built upper direct from Grendel Hunter?so I need to set up the adjustable gas block but the mlok handguard is in the way of the set screw.
To me its super nice and logo specific to the build (Grendel Hunter brand). At first glance it looks like many other handguards but closer look, its geometry blends in with the non milspec upper receiver geometry. My guess is I dont think I could find a replacement that matches the upper reciever...Is it a super nice handguard you hope holds value? Does it need to be clone correct?
If not, make the hole(s) you need.
I havent shot it yet, I just got it a week ago. It was custom built to my specs by Grendel Hunter. I dont think this is one to modify, I just wish I didnt have to remove the handguard to adjust the gas flow.Was this a factory built upper direct from Grendel Hunter?
Assuming you're running factory loads, I would think they'd already have the gas adjustment set.
Have you shot it yet?
It sounds like its a one time adjustment so not worth modifying. But regardless any temptation I had to dremel some clearance has been snuffed out now.So my adjustable had two screws as well.

I initially set mine full open. Was getting roughly a 1 o'clock ejections. Removed the handguard and turned the gas screw down one full turn. Was getting consistent 3-4 o'clock ejections and I never touched it again.
Copy that. Considering the company I'd be shocked if they test fired it and didn't adjust the gas if it was needed. I'd send a box of factory loads through it and see how she acts. If you're cycling and ejecting correctly then you've got nothing to do but enjoy.I havent shot it yet, I just got it a week ago. It was custom built to my specs by Grendel Hunter.

If I recall, all Grendel Hunter upper builds are test fired. But I dont know if that means they adjusted the gas block.
If they test fired it I cant find any wear on the BCG. Finally some marks are showing up from me cycling it. The entire upper is pristine.Copy that.

Did you get a used target and maybe even a couple spent cases. A lot of times company's will ship these items to show its been tested.If they test fired it I cant find any wear on the BCG. Finally some marks are showing up from me cycling it. The entire upper is pristine.
I think thats the plan, I need to find some factory ammo now and will be reading up how to adjust it and proper cycling and ejection. It doesnt sound too complicated.
nope, nothing but an invoice. It came well packed in a very discreet plain box.Did you get a used target and maybe even a couple spent cases. A lot of times company's will ship these items to show its been tested.
In any case, ya gotta shoot it to know where its at and then work from there if needed.
None of it is overly complicated, but its ALL tons of fun.
