Thanks nalioth & saigafreake.The extendable stock is very nice and is compliant,but I would prefer the fixed skeleton stock shown on the Centerfire Systems site,....only it does not list "compliant" or location of manufacture.Does anyone know if it is USA made or if another site carries a US clone?
The piston replacement sounds relatively simple.Who carries a reasonably priced made to fit(drop-in) US gas piston?What do you think of using permament threadlocker on the new gas piston threads,and tacking the holes after drilling and replacement with a MIG welder and dressing it smooth wi
