can you help a mag noobie out?

[kenndogg]

Ok when I shoot slowly my velocity is consistent, but during faster strings it get major drop off. any ideas?

[athomas]

Have you tried cleaning everything including the regulator?

How old is the gun?
When is the last time it was working fine?
What aftermarket modifications have been done?

[jayel579]

what kinda of air system you running on it, N2 or CO2?

[kenndogg]

athomas: bought it used, previous told me it was oiled and cleaned. Was told the orings rings were replaced. Looks like a pretty old mag. No aftermarkets on it.

jayel579: I run strictly N2 on all my guns.

[jayel579]

well i think you have a classic valve. are you getting at least 800 psi into the gun? that will effect shot down on an AGD valve.

[kenndogg]

its bulldog preset. I'm using a kingman mini x-chamber(don't have a gas thru) on it.

[athomas]

The expansion chamber will have an effect on the recharge rate. You should get a gas through or at least bypass the expansion chamber.

Check your on/off assembly, specifically the on/off top. If the top has an X cut on one side it is an old top. Make sure the X is facing out of the on/off hole not in towards the center of the gun.

are you sure the exchamber is an exchamber

kingman SAY their gun comes w/ exchambers, but really they are gas thrus

[kenndogg]

now that I look at its hollow.

[hAppy]

haha i got pissed when i found out too

hmm now for your problem

whats your tank output? i forgot my mag stuff but everyone uses 800 psi tanks

[Kevmaster]

bulldogs are 850psi I think...maybe 800...at least enough to work the mag...unless its a specifically LP tank...

check the airlines...you may have a piece of teflon tape or something blocking part of an airway.

if thats not it, your reg seat may be bad, or your reg springs may need oiling/greasing
