Stripped USGI fiberglass stock

For those wondering what one looks like, this is a completely stripped USGI fiberglass stock. It was stripped using Citri-Strip, which is a safe, orange smelling paste.

This particular stock came off of an early SAI Socom model. It had the black krinkle-paint on top of the brown USGI paint, which was on top of the base epoxy/gel coat.

As you can see in the pictures, there was an arsenal style repair to a crack in the right side of the forearm. A groove was drilled out and a piece of metal inserted. The inside was reinforced with fiberglass mesh and epoxy. Repairs like these are most likely why SAI coated these stocks with the heavy krinkle paint. RNGR2

You can also see where SAI filled in the switch cutout.

It varies. The paste lifts the paint as it dries. Cheap stuff like the krinkle paint starts to come off in about 15 minutes. The bottom layers of paint can take a few days to a week. You need multiple applications, scrubbing off the loose paint with a stiff brush or scotch pad.

I have no plans for this paricular stock, it is a spare. If I were going to paint it, I would degrease it an use Brownell's Aluma-Hyde, which is epoxy based.

New ferrules are available from Brownells for $6, and Fulton Armory has new sling swivels.

Thanks for sharing, I've never seen one in the raw. I didn't think Citri-Strip would take off the GI paint and gel coat; I guess it just takes a while. How did you keep it from removing the filler in the switch cutout? I would think it would at least soften that also unless you are very careful not to let the remover sit on that area after the SAI applied paint is removed?

Citri-Strip is pretty mild. It takes paint off easily, but takes a few applications and some scrubbing to get off the base layer.

It does not seem to effect the filler used to fill the cut out. SAI must use some sort of bedding epoxy (devcon, steel-bed?). It also doesn't effect the epoxy used to hold the 2 halves together (green colored).

You will always find stubborn areas when stripping the stock. Keep in mind that this stuff has been dried to the stock for over 50 years. Use a brass brush or scouring pad to rough up the paint between applications of CitriStrip. It will help the stripper paste dig in and lift the paint.
