What is the main spring size of the B26?

[jberenyi]

I want to get a full power spring formy B26 from JM. Anybody know a good one to use? I want to trick this puppy out with a new guide and the works like my B28.

Try that, I had mike hook me up.Best money I ever spent.That's the spring Mike recommended for stock power with benefit of an upgraded quality spring.

Good luck,I bet Mike will chime in sooner or later and give you some helpfull info.

What about JM's Tarantula or Hornet springs? They say it fits the R9 and some Chinese too.

They will be a really loose fit on the rear guide, need to make a new one or get the Hornet kit
