Answer 1

Well if you have had the gun a while the spring gets weaker and weaker.

Have you ever heard of out of the box fps? Many guns shoot faster than there normal fps in the beginning.

If any thing else. You can put a 120 in your guns and a few other upgrades and you could get it back to normal.

Answer 2

Check ur gears, motor, and grease ur parts.
