DM8 BPS Issue, Need help.

My son has a DM8, and it is shooting from 190 bps to 303 or so when chrono'd
Extremely weird it bounces back and forth the whole time...Anyone got any suggestions on what would cause this and how to fix it...BTW it has a brand new battery in it, which I changed it at field and nothing changed...still bouncing...

You mean FPS.

heres what you need to do

1: Set dwell to 21

2: Set LPR to 3 1/2 turns -4 turns

3: take bolt apart, relube it, replace the two tail 011 orings.( try this first you might be able to get away without cleaning reg)

4: Take apart your reg, and clean/relube it replace the piston oring,(015) (this is going to be the main issue here probably needs a good cleaning)

but to just be safe you can do both of them and eliminate all issues.

Now if you want look at my sig, for 25 bucks I will rebuild whole gun, lube it, tune it clean it etc and ship it back to you

check the reg seat in the reg. (black hockey puck looking thing)
flip it over if it has deep groove circle in it.
