As a german. If we already make POM spring guides - why don't we use the a size in our rifles that's more snug so there's no twang. I can't understand it. At least do away with guides that have like 2mm of slack in it.
Most German springers are too long. The Brits had the right idea with the Lightning and Stingray Carbine.
Their lengths are at least pretty close to right. Most of my rimfires fall in that 38-43" mark as well. Add on a muzzle device and easily 6" longer. The 97K and 50S are a very comfortable 40" while the 95 and 80SLK are about 42-43". Even most reasonably powered Gamo rifles are 45" while the Gamo Magnum is pushing 50" (similar to the Dianas). Let's not even start on Hatsans lengths haha I'm not saying they couldn't be shorter, but for the most part they are on par for the industry.As a side note, the 80SL and SLK are also rated at two different power levels on Krale. Not sure if that has to do with the shorter barrel or f maybe they softened the spring to make it easier to cock with the shorter barrel. Could also be a typo?
