TM SG1 Spring

Arcto

Hey,

I had not gamed with my TM SG1 in aprox 1.5 years. Over the weekend I chrono'd it and it was hitting avg 200fps with .20. Originally it was bang on 325 with the same.

Few lads said it was most likely the spring. What spring can I purchase to get it back on form and suggestions of where?

Thanks!

I'd say it's the piston head O-Ring receded reducing the volume of air behind the BB.

I would sincerely doubt that it's the spring

How would I check that? Take it apart and see if it looks screwed?

I've only taken it apart once, many moons ago

Simply spray some silicone oil into the air nozzle, and fire on full auto for a while - then re-test on the chrono

Exactly what he said - works almost every time.
If it's stock TM and not messed with it's most likely just some crud and a dry o-ring aorund the piston head. The silicone oil will relube it and give you a better seal.

Will try that. Cheers.

It's not a stock SG1 either, has a 1J upgrade.
