Welsh Willy Spring Service Kits are manufactured by myself  and are not available straight off the shelf,  I have been making these kits for the last 10+ years.  I listen to my customers feedback & If i can improve on my products I will try to do so, I design, manufacture & test the kits here myself before I let them loose on the open market, nobody else designs the kits for me, I buy the rifle design a Kit that’s the reason why I have so many different service kits available. Every kit is hand made, every spring varies slightly internally & externally, the delrin guides & Top-Hats are made to fit that specific spring in the kit. I use Titan springs in the kits and have found they give excellent results, the Titans are all cut to ensure they give close on the exact performance the shooter needs, so you don’t have to do any cutting of springs, all thats taken care of.
