I have a USGI fiberglass stock that needs a little snugging up arond the reciever legs to take out some wobble. I could ($100) get a complete bedding job done but would like to try to just snug it up a little myself. Also need to try to get some "down pressure" on the front ferrule. Anybody ever done this or think it would work using JB weld? I know it won't equal a real bedding job, but I want to put the next money into unitizing the gas system, trigger job, etc.

JB will certainly work, but it will not last long or be as durable as some other bedding compounds. Marine Tex is better IMHO and is not that much. It is available at your local marine store, or should be.

Thanks. I knew it wasn't a perfect solution. I was just trying to get the slop out. This rifle(Polytech) looks like it's going to be a shooter. So far, it's doing 1.5 to 2 MOA with LC and DAG ammo and I haven't gotten to Port yet. It will be a step at a time project as funds are available. A true bedding job will be the biggest single expense @ $100. Everything else will probably run another $200 on top of that. ETA : There are two things I won't tackle myself :a trigger job and bedding.

Shimming the gas cylinder can make a noticeable difference all by itself.

Well spent 7.00 dollars

My gunsmith actually doesn't recommend shimming. He says unitizing is all that's necessary and that shimming causes vertical stringing as the gun heats up. I'd be interested to hear what others think on this.

Dano - I'm just passing along what my gunsmith(Ronnie Morris of Match Service Works) says. He's not the only person who holds that view. As a High Master shooter and a nationally recognized M1/M14 smith, I'll let his work speak for him.

Try JB weld with flox(short fiberglass strands) mixed. Never Cracks. I've been using this for years.
