Yankee Hill Machine Low Profile gas Block - .750 - Pinch Style

this doesn't fit under a midwest industries handguard. the bottom is too large, and the screws protrude too far to the side. I had to machine it down almost to the threads, and cut the screw heads down at a 45 degree angle to get it to fit. I can't see how anyone would get this to work with low profile handguards without it touching.

I put this on a Rosco 13.7 barrel. For whatever reason, the barrel widens slightly before the gas journal. Installing a set screw gas block would require some excessive bashing with a mallet to get it it seated correctly, but this clamp on installed without issue.

I wanted to try out a clamping style gas block so I ordered this one. Today, 7-22-21, I received the gas block but it's not clamping style. The packing slip and the YHM package it came in have the correct part number (YHM-9384) but the part is incorrect. I received a 2-set screw gas block. Bummer.

Great clamp on gas block had a problem after barrel upgrade this gas block seals really good. AR cycles just like it should.

I have used several of these and for most part are great gas blocks. However YHM must be using cheap screws because while taking one of a rifle the head of the screw stripped really bad as if it were extremely cheap (China quality). I probably now have to cut off the gas block and extremely disappointed with YHM!

This is probably my 4th yhm fgb that ive installed or bought for my friends and person rifles. Theyre good stuff for the low cost.
