Nice, but doesn't fit - FM Products Premium Click Adjustable AR 5.56 Gas Block

I ordered this reading about it and just seen AR-15 adjustable gas block, and AR-15 gas tube height, but what it doesn't say is that their made specifically for FM barrels. Even though that they may fit (some) others and not have clearance issues, with a lot of free float handguards M lok etc, it may be close to top of the rail or what i found out the side where the set screw is located. It sticks out some the way it's machined and when firing the barrel whip could cause it to hit the inside of the handguard creating accuracy issues. Other than that it's really well made, just like any other click adjustable gas blocks, and even though it wouldn't (because of detent) the set screw allows you to lock it in place so once you get it dialed in, you'll never have it move on you. Although if wanted to change something, you can easily loosen, adjust to the next preference and in a simple process. Also the deep Melonite finish is pretty good and adjustment clicks are tactile and audible.
