First round shootdown

[Criticalhammer]

Lately been experiencing first shot shoot down.When the marker sits for a bit: pull the trigger, bolt sticks, air leaks out. Have to clear the chamber and push the bolt back with my finger, then everything starts to work again.

Also, after about 1 second of holding the trigger down the bolt starts to "cuff" in a slow choo choo style cadence, then the bolt eventually gives out a long hiss, then repeat 1 second nothing happens..... There is a o-ring that needs to replaced, but don't know what.

Change the oring between the on/off half’s and the top small oring.

and clean and lube the reg piston and reg cylinder while you are in there.

The reg should keep up with little leaks, making a normal leak hiss instead of intermittent chuffs.

The official AGD Tech Video is the absolute best resource for these markers. It covered EVERYTHING, except Lvl 10.


For the chuff (called "the lawn sprinkler")

Bolt stick:

It isn't bolt stick he is experiencing. The first shot drop off is from the dump chamber slowly leaking through the bottom small oring in the on/off assembly.

Bolt stick would be weak spring, incorrect spacer size.

Wouldn’t the reg just recharge the dump chamber to make up for such a leak?

[Criticalhammer]

Swapped out the both small and big on/off orings and now everything works! Also, remember to add some oil the first time you air up. It will help reduce o-ring wear.

Looks like im experiencing it again. Not nearly as bad. But I'm starting to believe its the black o-ring that needs to be replaced. What are the steps to remove that?

[superman]

you can just cut the old oring off and stretch the new one over the end of the stem.
That was the oring i was referring to above.

[Criticalhammer]

Really afraid of bending the tiny SS stem.

[superman]

That is why you slide the oring up and you can use some scissors to cut the old one off. The replacement one should slip over pretty easily. If the replacement one is hard it is too old.
