Chassis with straight adapter - TANDEMKROSS Straight Upriser Chassis For Ruger PC Carbine

Well, if you like tight tolerances and no gaps in your tools, do NOT buy this chassis. The adapter mount for the buffer tube is not machined to match the mounting surface and therefore when you tighten it, it opens a pretty ugly gap. On my chassis, if I torque the screw to 25 in lbs, I get about 3/16 gap between the chassis and the tube mount. If I torque to the suggested 30, it's more than 1/4 inch. When I reached out to the tech team at TK, they said it's normal and "1/6 of an inch is built in to not effect the trigger module" - this doesn't make sense as not only does it not mount close to there, but it uses the factory mount hole.. otherwise I love the built-in ambi mag release and the Honeycomb Hex grip is awesome
