WE Glock 17 upgrade help

[willsterman2]

Hey guys

 

Purchased a WE glock 17 about 2 years ago. Over the last few game i used it it I noticed that the range had decreased massively. Tried adjusting hop up but it did not work. Compared the range with my brothers TM glock 17 and his range was great. When I got it I added a new spring, don't know airsoft parts but it was something like 125% spring. What could I upgrade to get better range/ performance? Looking to do this as cheaply as possible.

 

Thanks in advance

First thing I do is take apart, clean & regrease/oil everything

 

My sons M4 dropped to 280 from 330, silicone oil on the piston o-ring and back upto 330

Cleaned, oiled it etc. What would I need to upgrade to get more range/ power?

Hop up bucking and barrel would help for range and accuracy.

Where would I get parts for that? Is there a good website?
