I have for sale a AMT Lightning 22lr, it is the same thing if not a little better then a ruger markII, it take the ruger magazines and I think all the same internal parts as well.The receiver has groves to put scope rings on it, has the target bull barrel gun is stainless adjustable site. AMT went out of business because Ruger sued AMT because they copped the mark II and the 10/22 and it ended up putting them out of business after the law suit. Asking $350
