Butt plate removal problem

I picked up a USGI M14 synthetic stock, cheap. It's in great condition, except for the metal which is rusted. I cut the front swivel off, but am having a rough time with the rusted screws on the butt plate. Any suggestions. It's soaking in WD40 now. I was thinking of grinding the screw heads off, taking the plate off so I can lube them better and using vice grips on the screws. Any other ideas?

sound like a winner. If you happen to enlarge the screw holes on removal;; just fill them with J> B>Weld, and than tap or dill them.

Thanks from Rich D

I'm gonna get flak for this but...


...ForgLube works. I have the paste on hand. Smear some wherever you can. If you have the FrogLube CLP drizzle some of that wherever it will wick down in. Then get the stock warm - out in the sun or in a metal cabinet with a light bulb going inside. That stuff melts and lubes the metals. Then try removing the screws with the whole thing warmed up.

Or try something like PB-Blaster.

I don't use WD-40 on much except removing decals.

I wouldn't use any chemical that might damage the stock. Remember it's polyester resin with foam filling.

I have several cheap stocks with the same problem. I'm going to dremel off the screw heads and try vise grips as mentioned above. Always destroy the cheapest part...

Sounds like a Synthetic GI project stock purchased on Numrich.com They are cheap and in decent condition but the metal is just rusted together. Try the clp trick doug said or get some of that rust be gone stuff or rustaway stuff from the hardware store. Put the rustaway stuff in a bowl and stand the stock up against a wall or something completely submerging the butt of the stock in that rust be gone. Come back in a couple days or a week.

Not sure this is accurate :)

I try to never use a petroleum (oil) based anything with plastics. The FrogLube is Coconut oil based and has never done anything to my Glocks, SAI ploy-stocks, USGI Synthetics or even wood stocks.

The plan is to put some 3mm square structural carbon fiber tubing under the top lip in the
fore end. I hope to tack it down with superglue, and then fill over the top with epoxy. What think yee?

OK this is going to sound a bit crude but it was the only way I could get the bottom screw out on the two stocks I bought from Numrich.
I took a hacksaw and cut down the back side of the swivel and pulled the bolt out, one one I had to cut in the front too because the bolt stuck out far enough it would not come out. After I got them out I fill the saw cuts with epoxy and sanded them flush. after paint you could not tell what I had done.
On another stock I had that the screw had broke off in the stock I took a piece of 1/4" tubing I had with a 1/8" id and put it in the hole and used a long aircraft drill and drilled a 1/8" hole through the broke bolt that allowed me to drill a 1/4" hole into the swivel and get it out.

Put the oil for the lower screw on the sling swivel.

Assuming you haven't already stripped the head of the lower screw, you can carefully use a plumber's torch to heat up the rear swivel. Tape some asbestos cloth or similar to the stock, surrounding the swivel.

The top screw can be removed by grinding off the head.

The "Primitive Pete" approach when all else fails. The "get a bigger hammer" school. That's where I learned everything! I was thinking along those lines as a last resort. On a side note, when in Viet Nam, we had supply problems(surprise!) and had trouble keeping penetrating oil on hand, as everything rusted. We ended up using wintergreen oil a lot. The docs had plenty, and it worked well.

If your is any thing like mine there aint no oil that will break that bond, I swear if I had not known better I would have thought they were welded. I heated mine with a heat gun until it was almost red [good heat gun] NO SOAP! that when the hacksaw came out.
