most AK stocks will fit with no issues primaryarms.com/MCategories+AK-47-Stocks

Your options are zero without an adpter from another retailer like CNC warrior, Carolina shooter supply, JMAC Customs, etc. Once you buy an adpter for the stock you want its just a matter of driving out the hinge pin. Ask me how i know...i own one bought here from Bud’s! This very listing. It has an RPK74M rear trunnion so if you have an RPK74M clubfoot stock and stock hinge piece it goes in perfect. The stock on it currently is a good stock though. Gives you options for an optic height setting using the cheek pad or you can rotate cheek pad for iron sight use. Cav Trooper 19D has a great Youtube video on this stock and other incredible AK knowledge.

Anthony, this will accept just about any standard AK replacement stock. carolinashooterssupply.com/AK_47_Rifle_Stocks_s/2100.htm
