Yankee Hill Machine Low Profile Gas Block - .750 - Set Screw Style

Installed this block on a BCM 410SS barrel. It was snug going on but fit was excelent. A no frills good quality part that allows you to mount a free float hand guard. Will consider for my next build...as always, customre service was bar none...shipping was fast!

It didn't fit my barrel at all. I even tired freezing the barrel and heating up the gas block with no luck. It may work for some but it didn't work for me.

It does what a gas block is supposed to do. Don't bother with fancy names just get this one if you need a basic low profile gas block. Seriously there is no point spending (wasting) extra money on a basic lo pro gas block just for a nameFit perfectly under a Midwest Industries Gen2 SS rail with plenty of room to spare. Don't listen to people who say this gas block won't fit under the skinny MI rail because it will. just make sure you get a roll pin separately because YHM doesn't include any. I used a DPMS roll pin and a Del-ton mid length gas tube and they both fit perfectly. Again, no need to waste money on fancy name parts in that area Only problem was I had to sand the inside of the block down a bit to fit over an AR Performance barrel but no biggie. Just a few minutes with sandpaper and it was done. At least it's better than being too loose.

it fits perfect from the barrel diameter and also the gas port is ver precise from the barrel gas port.

It fits, but it was tight. Went on with a couple taps.

It's a gas block. No need to over spend.

It's a quality piece but to me a gas block is a gas block - what really set it apart was the fact that it didn't look like it originally came with a roll pin from Yankee hill but had a roll pin stapled to from the guys at primary arms. That made my day since I dropped the one I already had in my garage and couldn't find it

It's inexpensive and works. What else can you ask for?

I've been very pleased with YHM good specs -good material-good craftmenship.

I've not received it yet.
