I was at practice this week and my Luxe was chopping paint. I assumed it was caused by blowback back because removed the hopper and put two paintballs in, fired and the second paintball popped up. I've cleaned and lubed the marker and replaced the SFT o-ring, tried again and still am getting blowback popping up the second paintball.

I've searched but could not find any other solution except replacing the SFT o-ring. Any help would be appreciated, thanks in advance.

Its more like due to the balls rolling forward in the breach thus causing the next ball in the stack to drop too low.

if using a rotor turn down the ball stack tension screw. this seems to help alot of ppl.

But I still have the blowback issue that I am unable to resolve. Any suggestions for this specific issue besides the SFT o-ring?

Try another Oring, remember all orings fit different.

Are you using an HBNR SFT O-Ring as DLX specifies?

I've actually tried a bunch of HBNR o-rings as well as the 017 90 Buna one that is suggested on the below o-ring list and still have the problem:

Do you have alot of wear on the tip of your bolt? Like an excessive amount? Something that could keep it from sealing when in the forward position?

No, I have a fairly new 2.0 bolt and it looks good, no wear.

Are you under-boring?

I was during practice but when I was trying again yesterday I was under and over boring.

Is your bolt guide screwed in all the way. The timing of the air release can be mess up the bolt guide isn't screwed in all the way.

While you are at it, make sure your detents are moving freely.

Bolt guide is all the way in and detents are moving freely

That's a head scratcher. My best guess is that the SFT oring still isn't sealing. I replaced mine recently and several of the orings I tried didn't seal effectively. I used the green one that came in my Luxe kit and that did the trick nicely.

I suspect the SFT is still the culprit.

I was having the same problem for a while too. I turned down my rotor tension and changed every oring on my bolt with black orings(compared to stock clear ones, is this a huge deal?) The rotor tension seemed to help quite a bit. I'm waiting to get my hands on a green SFT orings to switch that out as well!

*Fixed*

Turns out that the 017 o-ring at the front of the can was faulty (apparently the first few that I used were), it was sporadically sealing which is why I couldn't hear the leak. Weird! Anyways I caught the leak today and switched up the o-ring and it is working now, no blowback.

Side-note though, my spring in my bolt wore out and snapped in half today...lol

Thanks for the help again guys.
