3D printed stocks and shooting accessories
Notice:
Due to other work commitments I’m currently taking a short break from my stocks and some shooting accessories until March 2026, so online purchases are temporarily unavailable. You’re still welcome to browse the website and explore all items — but I’m not taking any direct orders at the moment. My eBay sales remain largely active and unaffected, so you can continue buying through my eBay store in the meantime. Thanks for your understanding and support!
Royal Mail Update:
Please note that my eBay shop will be closed during December. The Royal Mail service becomes extremely busy over the holiday period, and unfortunately, too many parcels go missing or are delayed. To avoid issues and losses, I’ll be pausing sales until the new year.
Thank you for your understanding and patience!
S400 stock guide
Step 1
Fit the front and rear sections together and fasten with two M5x20 button head screws and flat washers
Step 2
Next fit your airgun action and fasten in place with one M6x70 button head screw and flat washer.
Step 3
There should be approximately 2/3mm gap between the air cylinder and front support section (forestock) This is to offer a "Floating action" which is preferred by many S400 shooters. If you find the cylinder is not in the centre of the support, loosen the cap head at the front and rotate the guide to centre the cylinder, re tighten. If you wish to add some padding or foam, that is up to you.
Step 4
If required, the hamster can now be fitted directly to the underside of the stock or use 1, 2 or all 3 of the spacers to set the desired height, using the two M5x70 countersink screws provided. If you wish to fit the hamster with no spacers, then please use the M5X40 countersunk screws
Please note the orientation of the rear hamster spacer, it has a cutout to fit around the stock mounting screw.
If a hamster is not required then please fit the 2 off M5X20 button heads and washers.
Step 5
That's it, all done.
Any problems please contact me
Enjoy !
