Anyone have any experience with the Fulton Armory Adjustable Gas Tube?  Does it work and allow the rifle to cycle without a hiccup?  Is recoil lessened at all?  Thank you.

The Fulton Armory adjustible gas tube works really well.  You can fine tune the amount of gas that is used to recycle the bolt.  It does soften the recoil a little but since the AR15 doen't have that much recoil, it may be hard to notice.  What I like the most about the adjustible gas tube is that it saves a lot of wear and tear on your rifle because of the reduced force of the gas to cycle the bolt and it also helps to keep the receiver much cleaner because less gas and fouling is going back into the receiver and bolt assembly.

More questions.

I got an adjustable gas tube from Brownells, not sure if Fulton Armory is the source.  I have not used it yet, but got it for use with a suppressor so I could dial down the gas return which increases when using a suppressor.

Now the question:  I thought I saw a post about someone having to loctite (or similar) the adjustment screw to keep it from turning under use.  Has anyone had this problem?  Is it a problematic concern?
