Is there any reason why a Spyder, initially using all stock internals, would start to have trouble re-cocking after switching out for a high flow valve/pin and a delrin hammer (without o-rings)? Is the flow too high? Maybe the drive spring is too heavy?

I switched out everything on my Victor II for a complete Alamo internal kit and it starts to BRRRRAPPPP and not re-cock. It shoots around 280 fps with the stock internals, HPR set to around 500 psi.

try a stronger spring

double check the o-rings, 99% of my spyder brrraps are caused by a cut ring.

Do you mean delrin bolt or hammer? If it is the bolt, then it may be slightly out of spec and causing too much friction. If you mean hammer, then it should have an o-ring to properly seal to utilize the blow back gases.

Try using one part at a time and trying to figure out which part exactly is causing the issue.

I have a delrin valve: SpyderHi-floValveKit

delrin hammer (no o-ring version): http://www.alamocitypb.com/MANUFACTP...erstriker.html

and a delrin JAM bolt.

Thanks for the quick replies.

My gut feeling is the lack of an o-ring on the striker. That seems like a serious issue especially since you mentioned that you are running a regulator on it to lower the pressure. But again, it would be best to sub in each part on its own to nail down the exact cause.

Thanks! I will swap out the striker with the stock one. I wish the Alamo site was a bit clearer; I don't really consider 500-600 psi to be "low pressure applications".

I wouldn't either when looking at it on the grand scheme of all paintball markers. But that is on the edge of low pressure for spyders. 500 psi is about the lowest I've been able to take Spyders without some major modification while still maintaining acceptable velocity.

But without testing the parts separately I'm just guessing that it is the hammer. Could be the bolt being a bit out of spec too. I've seen that with other blow backs (RAP4 T68). The anti-chop bolt in it felt fine, nice and smooth, but it had nothing but recocking problems. I switched it with the stock bolt and everything was back to normal even though there was no descernable difference between the two bolts.

Once you go into the whole modding the internals...you'll need a spring kit to strike a balance for your valve.

You can only turn your velocity adjuster in so far before it has recocking issues and I have a feeling your hammer is now too light and doesn't have enough weight to strike the valve with the stock valve spring hard enough to recock it. Not to mention no oring on it, you should have opted for that since you're doing low pressure.

Spring kit should fix it.

Thanks guys. I am going to narrow it down to the hammer next time I have air (I have a spring kit already) and I will probably order the o-ring striker from Alamo.

jusst throwing this out there but we had a guy with that issue and he asked me to look at it. all it turned out to be was the detents was too guncked up. check yours and see it they are damaged and clean.
