Gas tube slid in easy
The gas tube fits a little loose. I don't shoot underpowered ammo but if you got a case of weak ammo, this might let enough gas bleed out to affect function.

worked perfect on Ruger 556.
worked awesome on Ruger 556. factory sight/block was really hard to remove pins. YHM block goes on super easy and tightens down easily. very pleased with this product.

Works well
Works well would've been 5 stars if there was a way to pin in place. But, other than that it's great. Went on easy, I had originally bought an ergo adjustable low pro for this build but couldn't get all the way down to the gas port so I went with this and I'm very happy with it !

Works well
Installed this on an A4. I was installing a rifle length free float forend, and needed something that would work. Bought this at a local shop, and it went on easy.
