    Easy to install, spring I’ve had gave me 1.36J and now after adding this I have 1.5J on the dot which is ideal for my field. Also with combination with the guide, helped with the sound. Would recommend.

    Super easy install and if you dont mind weighting (stock srs piston is quite light)your own piston it works amazingly.
    Only minor gripe is with lower power springs the airbreak seals so well you get some piston bounce, no negqtive impact on performance it just sounds funny.
