New Model Daisy 25 Power Upgrade Kit- The Spring Is Custom USA Manufactured For Sale

This is being sold for use in the current China manufactured Daisy Model 25's as a power upgrade kit!

These upgrade parts are brand NEW, the Air tube is Daisy and has a 2-stage modification process done to it, its been bored over-sized and the air intake port has been ported (not enlarging the cut) to better optimize & direct airflow.

This spring is aNEW USA custom manufactured spring, this upgraded spring has been designed to have a slightly longer un-sprung length but with the same average number of coils, when installed this gives it the same compression range with more compressed preload, this spring is close to 6.5" long. (the standard available M-25 spring from Daisy is 6" long).

The design of the spring helps to get a little more energy out of it without so much internal abuse to the gun.

These spring's did NOT come from any company's regular inventory, It took me several Months to work out the details of having these custom manufactured, after all the redesigning & final production of these springs I purchased all the production pieces! These springs Are entirely brand new!

I've personally tested these kits in two of the current China Manufactured Model 25's & in both cases I got averages of 40fps to 60fps increases over the OEM stock performance without any other upgrades, and those numbers are actual chronograph results!

I can't guarantee everyone will get the same results but I don't see any reasons why they shouldn't if the BB gun is in good working order. I have extensively tested these upgrade parts in two different test guns I have without issue.

Because This Kit Has The 3.5" Air Tube It's Not Intended For Use In The U.S Vintage Model 25's
