Customer Comments:

"Excellent quality and attention to detail. The replacement firing pin and spring retainer are a nice upgrade to the original design. Fitting was simple and straightforward with good instructions. Unless you wanted a mirror polish on the shroud , the parts are ready to be blued with no additional polishing for a nice satin rust blue or light matte hot blue. - Jeremy"
