http://texasakdesigns.com/products-page/ak-rifle/ar2ku223-aksaiga/ This is the Texas ak designs / Magnolia state armory magazine adapter for saiga .223 rifles. It allows you to use ar-15 mags in your saiga. I decided to just convert my saiga to galil mags instead. It has never been installed but has some scrapes in the paint or whatever they coat them in. YOU DO NEED TO GUNSMITH YOUR RIFLE TO USE THIS. NOT DROP IN... Looking for $60, in the chehalem valley area. Will throw in two Pmags (window-less) for $75.
