I stripped the paint off a No.4 Mk1 last year. Once you have the barreled receiver separated from the stock, liberally coat the painted areas with standard paint stripper (I use Jasco brand). After soaking for about 15 minutes, you'll be able to remove the bulk of the paint with a toothbrush. For the stubborn areas, 0000 steel wool does the job. You may have to repeat this process more than once, especially in hard to reach places. When finished, clean the metal with acetone to remove all traces of stripper. If you wish to paint the metal to match the original appearance, use Rust Oleum Satin Black (stock #7777). Spray on two light coats, waiting 15 minutes between each. Then add one heavier coat. Once dry to the touch, bake in an oven for 2 hours at 250 degrees. It will look GREAT and mine has held up real well to all cleaning solvents. BTW, all of the metal on the rifle (stock tips, swivels, screws. etc.) look real nice painted the same black.
Good luck
