About Us

Tuning and customising the Crosman 22XX and 13XX range of guns is great fun, and once you realise how basic and easy these guns are to work on, you will, like us, be addicted to tuning and customising your Crosman. We have spent years customising these guns and searching the internet for new parts to come up with new designs, most of which can be seen in the gallery.

At that time there weren’t any websites in the UK that sold these custom parts, hence the reason for starting the SD Custom Design website. The website is dedicated to supplying quality parts to like-minded enthusiasts in the UK and from around the world. We also pride ourselves on being able to provide excellent service and advice on this range of guns.


Please take your time and have a look around the site, and if you need any help or advice, just get in touch via the contact page.


If we don’t have what you want, we can usually point you in the direction of someone who will.
