$14.99 is a lot for a $2 piece of plastic but I ordered one of these on sale for $12.99 from PSA today. They come in .625" for A1 barrels, .750" for A2 and most other barrels, and .936" for bull barrels. I don't know if that would squeeze down to work on a .875" barrel, but I don't think many people use those on AR-15s. On AR-10s a lot more often, I'd guess. From everything I've seen you DON'T need to have the gas block forward of the shoulder on the barrel, the thickness of the handguard cap. The hole in the gas block is big enough that it doesn't matter. But, why take a chance when this tool makes it so easy to line it up right, without a cap on the barrel, or holding a shim of the same thickness? Also, when I talked to one of the companies that makes AR-15 parts, they said barrels DON'T need to be dimpled for set screws. I can check my email to see who it was if anyone wants to know. I'll be using green Loctite for um-threaded sleeves when I put mine on, and heating it up with a heat gun to activate the Loctite. I'll use Loctite on all 3 set screws too, and it will never come apart unless I heat it up with a torch.
