Tinbum Tuning Ltd (TbT)

Bought a tuning kit for my Stoegerx20, which was easy enought to fit and has noticably reduced the recoil. So much so that the gun is now a lot more accurate. Money well spent. I would have given five stars but for the time it took to get to me. I would have been happy to pay a little more for two day delivery.

I've ordered two weihrauch tuning kits from Nick and wow what a difference to both of them. No more twang noise and so quiet, especially if you wet and dry fine grades and polish the piston with autosol videos to follow and if you get stuck he answers email and telephone calls promptly. Definitely recommend that you try one of his drop in Maxi kit's and if you order before 1pm mine were both delivered via royal mail the next day. I didn't fit the new springs yet as with just the delrin spring guide top hat slip washer and power washers have given more power and still under the limit. So I will keep the springs for a few years time or if I decide to fit the short stroke fitting. Before and after polishing piston below. Thanks for all your help Nick update after a 1000 pellets later I had to remove the power washers as they took the power over the limit. So just the tune up, top hat and delrin spring guide took it up to a fraction under the limit. Very happy with this drop in kit and instructional video tutorials.
