Ive allways wanted a spas 12 I know theyre supposedly aweful. I just want one. I had considering trying to get a sas-12 or a pa8 and buying a high quality metal airsoft Spas-12 to scrap for the pump and heat shield. They make metal folding stocks but I dont think they would hold up ,might be wrong, question is where the pump doesn't have to take alot of stress and the heat shield is metal could this be done?
