Luke's Customs On Off Reset

[HoneyBadger]

New to Automags and even newer to troubleshooting. Built up a ULE X Valved automag (ULE body/ rail and RT sear). Everything is new except for the trigger frame that came off the original Classic. I recently picked up a Luke's Customs On/Off and a couple extra pin lengths. Shipped with the .70 installed and have a .71 and .72. Marker is running at 1000psi.

.70: Gassed up, pulled the trigger, mini gun like burst until I let off the trigger and it wouldn't reset. Began leaking down the barrel.

.71: Gassed up, no barrel leak, would fire a few rounds and fail to reset fully.

.72: Gassed up, no leak, no reset issue but rapid fire has a dramatic "shoot down", losing velocity/distance/accuracy.

None of which occurs with the stock on/off assembly. The r/t effect is notably softer, lighter trigger pull and overall, feels as reviews say it should. My understanding is the Luke's Customs On/Off is generally compatible with most components except for some valves.

One thing I do notice is the Classic frame being polymer does have a section rear of the trigger where you can see the length of the sear between the frame and rail.

Is it possible trigger frame is "out of tolerance" given the rest of the setup?

Any input appreciated!

You could have just contacted me via email and I would have gladly helped you out. Put the .70 back in, put a few drops of oil down in the bottom of the on/off hole, reinstall the on off, turn up your velocity, do what you have to do to start cycling the marker to break in the orings. If you get a hiccup just keep cycling the marker. Keep cycling until you get constancy with the trigger pulls. Then re-chrono

Thank you for the response! I hope my post didn't come across the wrong way. I figured to start here, do my due diligence and try for a better idea of what's going on before going straight to you about it.

I'll give that a shot and see what we get!

I just got one of these for a classic valve. Do you recommend the same procedure Luke? Might mess around with it tonight.

Just put a few drops of oil in the bottom of the on off hole, air up and start cycling the marker, 99% of the time that is enough. That said sometimes the orings are tighter than others so you need a little help to get the pin moving under pressure. Increasing the velocity pressure helps get things moving..

Awesome thanks.

Any updates?

Yeah, I ran out of air, hahaha. Put the .70 back in, cranked the pressure and it's resetting a little more consistently. I still have a ways to go, but progress is being made.

Just keep cycling until you feel its resetting pretty good, then rechrono, even after that it should get better the more you run it.

Sounds good! I was confident it was nothing adverse, just something I'm unfamiliar with. I keep looking at your Z grips and will likely order one, soon.

On off oring break has been a long time problem for those unfamiliar with that particular issue. I've had many dozens of "unworking" Mags come through my shop that only needed the on off orings broke in.
