I need one of the non extended mag releases for a 10/22 (Ruger calls them magazine latch). I thought this would be about the easiest part in in the world to find, but no. Midway, Brownells, Numerich, ebay, Gunbroker etc not one single listing. Is the current 77/22 release the same part as the old 10/22 release? Can I just stick one of those in?
