Need part number or source for 15lb. Hammer spring

[Bob La Londe]

Norm at Discos R Us has them. He also has adjusters turned down to fit the heavier springs if you don't want to turn yours down.

Anyone else has some extra info?
I fill 210bar and shoot till 140 bar and get 20 shots.
no idea what speed but def a lot harder th. With stock spring.

In .480 dia x 2.5 length only 13 or 17 lb that I can find. SS in .059 will be close I think if you can find one 2.5 "

This is 15, but .420 dia x .055 http://www.amazon.com/dp/B005KSUWSC/ref=biss_dp_t_asn

Guys,
I make a custom dual wire spring out of .0475" PH material. Fit is made for the marauder. I make them at 2" or just below for negative preload. 2 turns on the HS is 0 preload. Spring is capable of over 20lb/in but at negative preload "HS0" and hammer cocked only gives the spring approximately 6 Lb's force (less than stock).

When fully cranked, the spring has way too much energy for my valve but, it is capable of delivering 140 shots at 12 fpe to all the way up to 50 fpe for 10 shots on my gen 2 .22 cal marauder.

There are no off the shelf springs that have the 15 to 20 lbs/in at the dimensions we need to fit the marauder without grinding or trimming the spring.I haven't found them yet.

I would love to see that war valve hit over 100fpe with my spring in a 25 along with de tuning to 40 fpe without using oring buffers to get an efficient tune. I know this spring will do it, I just need someone with a WAR valve and time to test out the spring.

Well Shorty, sell me a spring. I am only getting 84 FPE with a 13# spring / WAR valve / stock hammer / 52 grain slugs / 3400# fill.
As soon as my new barrel gets here ( hint Travis ) I'll be hot on it.

No problem. Is there a way to PM here ? I am on GTA as Shorty too if you want to PM me there.
