Welcome to GMAC Custom Parts Limited.

Established by my late father Gordon MacMillan (Mr GMAC) over 10 years ago. His passion for guns and in particular Crosmans, sparked the interest in making the spare parts, most in brass which is the traditional material used by gun makers for centuries, and more recently anodised aluminium.

I am continuing to run the family business and will be progressing the business with new ideas and new parts. We are based in the UK and welcome orders from overseas. All stock items will be posted within 24 hours of payment on business days.

Our new website is a work-in-progress, if you have any queries please do not hesitate to contact me.

Kind Regards, Stuart MacMillan
