AR-15 Gas Block LP 0.7495

Other reviews stating that it will not fit are true. Will not fit any of my barrels. May it will fit Yankee Hill Barrels. Measured Inside Diameter at 0.7495, it should be 0.7505 to 0.7510. Disappointed, Yankee Hill makes some great products.

Don't waste your money!

Have to send it back because it won't even seat all the way on my Rainier Mike Rock 18 inch SPR barrel. So then I tried it it on a spare Voodoo Innovations 16 inch government profile barrel and it won't fint on that barrel either! I can slide it on about half of the way down between the muzzle and gas port and it gets stuck. I doubt both barrels are out of spec.

Out of Spec

The YHM gas block is way out of spec. You will need to use a brake hone to take a lot of material off the ID in order to get this to fit a barrel. YHM really needs to do some QC on these. Luckily Brownell's has an amazing return policy.

No Good

Attempted to install this on my bushmaster upper, went on about 1/3 of an inch then required excessive force to budge it. Definitely not the correct size. Maybe quality control needs to be upped at YHM as this is a recurring problem. Scratched gas block trying to remove it and now i cannot even get a refund. Try a different company is my advice.

would not fit

I attemped to install the as block on ar-stoner barrel and it would only go on about a quarter of an inch. After removing the gas block an checking the diameter of both the block and the barrel the gas block was made to small.
