I can give you a simple solution, have done several of these risers, along with Bear Minutemen, and 76'ers, not to mention compounds with mag/alum risers. I go to a local parts or machinist, pay them $5 and use their bead blaster for 10 minutes to clean all the old paint etc. off. Then I degrease/clean with acetone, get at WalMart, and let dry. Screw a bolt into the stab. holder and wire up a wire hanger of sorts. I wear rubber gloves during the degreasing, and any time after I clean it. I usually use the acetone twice, first time to get any unseen gunk off, second time as a precaution. Then I use Brownell's Aluma Hyde 2, requires no primer, and you can put 2-3 coats on, as long as you do them within 1/2 hour of each other. This is available from a rattle can. One can would do 2-3 bows.This is a slow cure epoxy paint, and will stand up well on abusive use of firearms and harsh chemical solvents used to clean them, much better than any paint that was used when the riser was new, available in several different colors. You will need to let hang4-5 days in a hot area of your house, needs to be done in a warm area also. If the riser will fit inside your oven, heat to 300 degrees, hang by the afore mentioned hanger, let bake for 30 minutes, take out and let cool over night. Will be tough as nails, unbeilevable. I have been professionally bluing and parkerizing firearms, and knives for over 20 years, this stuff is toughter than either, never had a complaint from a customer. Not too expensive either. Go to Brownells. com or call them on their tech line for help. Pm me if I can help further.
