I've looked at just about every online retailer over seas for a RIS for my M249 and I haven't yet seen one made of ABS, and there doesn't seem to be very many choices either, so I ended up getting the one made by G&P for $80US, althought the same place that I got it from had the one made by CA for $79US. Some place have most M249 RIS listed as either out of stock or discontinued. Just cause it's and A&K, you don't have to cheap out, I've got an A&K and I've spent almost $400 on after market add ons, railed top feed cover, RIS with a RIS mount bipod, CA made hop up chamber, tight bore barrel, different flash hider, MK46 buttstock.
