I ended up putting Hill barrel bands on all my Benji's. Problem solved.

Swapped out the hammer spring with a shorter/stiffer one and went from getting one mag in the low 900s with 15.89s, to now getting 3 mags with same pellets in the 850 fps range and considerably less noise and shot cycle vibration.


Todd, what size spring did you use and where did you get it?

It came out of a kit of springs I got off eBay from a company called Swordfish. I'll check the dimensions when I get home and give you the specs. I never tried it in the full length barrel and airtube but I would bet it would really extend the number of shots and bring the bark down while keeping the power still pretty good.

This is the kit I bought, was suggested to me by BeauJames on here actually

https://www.ebay.com/itm/181941373759?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=0d0jQWdjSEa&sssrc=2349624&ssuid=bfxzi0rkqxk&var=&widget_ver=artemis&media=COPY

Spring I used was: .054"WDx.437"ODx2"L
It's shorter, stiffer, and smaller diameter but works great

Sweet !!

Did you had to do any adjustments to the stock to make it fit the NP03 action actually ?

I fancy the Kral Empire XS, kind of similar set up though more like a bullpup. I like your version way more since it is a standard stock one. Hence I'll check if I can buy the NP03 one too and then the stock only.

Nope, the action is from the mega rifle and the air tube and barrel is from the NP-03.

To swap just the stock to an NP-03 you would need the mega/jumbo trigger which is hard to find.
