Cannot use with a bcm handguard - Seekins Precision Low Profile Adjustable Gas Block

Got a criterion heavy barrel, .750, installed this gas block onto it, all seemed well, then I installed the handguard, and boy was it hard to get on, had to heat it up and bang it on with a mallet, but then I noticed a few minutes later that the bottom of the gas block was a hair away from hitting the bottom of the handguard, and any pressure would make them make contact, so for my precision Bill that was a no-go.

Looking into other low profile gas blocks I realized most use a 3/16" set screw, which is about 4.76mm, this seekins uses 15/64" which is about 5.95mm, so thats a 1.2mm difference , not a lot but it is enough, I can't fully blame the gas block since I hear this handguard is pretty slim.

I was thinking about grinding the bottom of it down to fit better, but then I realized when the handguard is installed, it blocks the side adjustment screw for the gas block, and for how hard this handguard is to get on and off it would not be something I would be able to adjust without an hour of work.

So for those two issues make an incompatible with my overpriced handguard I cannot recommend this.
