TM Mk23 Trigger Won't Reset

[PDribbles]

Good day and thanks for taking the time to check this thread. I hope someone might have a solution for me.

I have a TM Mk23 that has not seen one BB through it yet (bought new). I have upgraded the pistol with a new barrel, TDC, hop plate, bucking (see https://www.skirmshop.nl/en/ultimate...-platebuc.html) for list of parts.

I've reassembled the pistol however the trigger will not reset after firing once. I have removed the slide so I just have the lower and the trigger works as it should. Fire, reset, fire, reset etc. I tried it with just the slide (no internals) on and it fires fine. When I put the internals back on something is obviously not happy. I don't know if its a lube issue? Fitment issue? Could a scouring of the outer barrel make an issue (the spot where you need to remove some plastic so the extended barrel fits)?

First time taking apart and putting an airsoft pistol back together. Super frustrated and hoping someone might have a suggestion so I can go play on Sunday.

Thanks again for taking a look.
-P.

My guess would be it's the size of the bucking. Try reverting to the old bucking with all other new parts and try that. If still nothing, old barrel, new bucking, new parts, continue in that fashion until it works, then you'll have your answer. If none of that works, then start the process all over again with 2 old parts and all other new parts (my guess is either barrel or bucking though)
