Thanks Dan. Will look into it. The TbT kit I tried. The guide broke after some use. Dont think it's made strong enough for High Otuput rifles
Hi, Morten. These are popular in the US and ship to Europe:http://www.airrifleheadquarters.com/catalog/item/251488/43393.htmhttp://vortekproducts.com/ourstore/Airgun_Tune_Kits/HW95_AirRiflehttp://www.airrifletuning.com/store/weihrauch-hw95-98-maxi-tuning-kit/I've had good experiences with products from all three companies. Good luck!
Air Rifle Headquarters=excellent tune kits. Let us know which one you get and the results please
TBT might replace the guide if you let them know what happened. I am running TBT HW77 guides with a .128 spring in my HW77K, and it is making 17-18fpe with no problems with maybe 500 pellets through it.
