Welcome to GMAC Custom Parts...
we are a family run business with the personal touch manufacturing and supplying custom made parts for the crosman 22xx & 13xx range the qb/xs78 range and the webley fx2000 and it's derivatives.

Most of our parts are made in brass a traditional material used by gun makers for centurys, don't expect anything on this site made by GMAC to be made in Delrin, the whole idea is to replace the plastic parts. All Crosman spare parts listed are genuine not  GREY IMPORTS  Based in the U.K. but welcome orders from overseas all stock items posted within 24 hours of payment

 

I am very pleased to inform you that we now have a approved stockist in Canada who will stock most of our custom parts
