Sharp lookin Ruger 22/45 Mk IV Lite with very little external wear and a low round count. As far as I can tell, Ruger has discontinued this neat looking "mint" color. Has threaded barrel just waiting for some suppressed NFA goodness. In my opinion, this entire line of pistols have been the best 22 rimfires on the market, bar none. Not to mention most likely the lightest, as the name implies.
