Nice gas tube, minus the sand.
I've used a couple of these gas tubes on different rifles. Excellent quality and finish, but it is a "gas tube." My only problem with them, and the reason I will not use them from now on, is the most recent mid-length tube I purchased was sent to me packed full of sand. I did catch it before I assembled it, but had to spend some time unclogging and cleaning it with a piece of wire, a pipe cleaner, and solvent. I managed to get almost a 1/4 teaspoon of sand out of the tube. Not a big deal but it could have been a hassle if I wouldn't have caught it. It is a nice gas tube, minus the sand.
