I have no problem with leapers/UTG or NCstar. You can get these at cheaperthandirt and many other online retailers. Even midwayUSA. Average price is under $30 each. But they make many different versions. Fixed, folding, tall, short, picatinny/weaver, barrel, etc... Might do some searching. But they are aluminum and will fit my needs. There's also some other no name brands, but I don't have any experience with them. I have a few UTG parts I bought for my AK series of guns. The metal is very good. "I've dremmeled through some of the rails and such to modify". Very good aircraft aluminum. Anyway, there you go.
