Cleaning gas block glue from DPMS barrel

[Rick O'Shea]

Hey folks,

I'm working on changing some stuff out on a DPMS LR-308 with a 24" SS bull barrel. The gas block was apparently glued in place at the factory, but the dried glue was brittle enough to break loose with a little effort on the set screws.

My issue is with the glue residue left on the barrel. I want to get this barrel Cerakoted, so it needs to be perfectly clean before I give it to the finishers. I've tried a number of solvents, including mineral spirits, denatured alcohol, kerosene, lighter fluid and Goof Off. Before I go to the hardware store and buy quart containers of paint thinner, MEK and acetone, I'd like to tap the wisdom and experience of the group to see if any of you have successfully tackled this particular issue.

Personally, my money would be on acetone, but I'd like to hear what y'all have to say.

Thanks, everyone.

Welcome to the forum feel free to post in the intro section.

maybe email dpms and see what they recommend maybe?

Thanks for the welcome.

I thought of checking with DPMS, and still might. Frankly, I was interested to see if this problem was common, or had at least been encountered before.

  If its Rocksett, used on High Temp. applications .

 

 

What is the proper way to remove a muzzle device that has been installed with Rocksett, and what thread locking strength is it similar to, ie blue Loctite?

The manufacturer recommends soaking in water for an extended period (several hours) and it will deteriorate. A quicker process would be to totally immerse in hot water for approximately 30 minutes and then break free with a wrench. Don't have a direct comparison to Loctite, but would consider stronger that Blue and approaching the Red. This product is desirable when heat-resistance is highly desired such as muzzle devices that will operate in conjunction with suppressors.

Yup, Rocksett! Soak it in water and then remove, piece of cake.

Water? Who'd a thunk it?

The universal solvent. Never crossed my mind. I think glue solvent and something organic like acetone or toluene seems appropriate.

Huh.

Thanks, guys!

Follow-up: I'll be dadgummed if water didn't do the trick! Wrapped a hot water-soaked washcloth around the area of residue for a few hours, rubbed it good, and no more glue! I dried the barrel off and wiped it down with an oily rag, and everything looks perfect. Y'all are awesome. Thanks!

Replying so I don't lose this thread...

I'll be removing the gas block from my DPMS LR308T soon. Looking at it, I thought it looked like there was some type of adhesive there.
