Autococker Trilogy using a Stock WGP Cocker Frame

[Cdn_Cuda]

Picked up a Trilogy Competition that has a standard WGP Autococker trigger frame (as opposed to a Trilogy frame) and having issues with timing. I’ll eat played with adjusting the hammer, but can’t see to get it to recock after firing.

Could this be a cocking rod issue? It needs adjusting? Any advice would be appreciated.

And while I’m at it, I have a stock empire valve, is it worth throwing it into this? Air passages are bigger, so air should flow better.

It could be the cocking rod but it's very unlikely. More likely is you LPR is too low or your lug isn't low enough. Could also be that the sear or lug is worn, or that the sear spring is too light.

Sear looked okay when I took it all apart. Orings were pretty much mush. Haven’t taken apart the LPR yet. Maybe that’s my next task.

WGP frames drop right onto Trilogies without adjustments needed, so likely something's been fiddled with.
Hammer lug is certainly possible. WGP swing frame is also very adjustable, so it may just have the trigger limiter set too short. LPR possible.

Does the back block cycle fully when you pull the trigger? -if not, LPR needs to go up
Does the gun cock when you just pull the cocking rod? -if not, hammer lug needs adjusting (OR internal trigger stop needs to be adjusted)
Does the gun cock if you pull the cocking rod all the way back and let it slap forward? -if not, sear spring is too light

It cycles, bolt moved as it should but it only cocks once every few shots. Gun cocks manually without issue.

Does it cock when you pull the back block and not the cocking rod?

[Cdn_Cuda]

Yes it does

[Alexndl]

If you pull the back block does the hamer lock when the bolt almost clear the breach?
and if you cock the hammer and move the cocking rod with your hand, does it release?
If you remove the frame and inspect the hammer lug, is it stock or have it been grinded round or pointy?

[Cdn_Cuda]

I’ll take a look at the hammer lug. Didn’t pay much attention to it’s shape. I have a few hammers and valve in my parts bin I can try

[Magmoormaster]

If you can cock it with the back block, and the back block is going all the way back, then it’s a timing issue.

Cock the gun and has it up, cycle it. Does it fire and then not recock or does it not shoot and stays cocked?

If the first is true, the cocking point is too far away from the cycling point. You’ll need to lower the lug. If the second is true, the cocking point is past the cycling point and the lug needs to be raised.

Looks to be a spring issue. The main spring is the wrong spring, so it barely even touches the IVG unless it’s bottomed out. I’ve got a pile o’cocker main springs thankfully.

I'm 90% positive that top one is the stock spring. Trilogy springs are usually that thinner gauge stuff. Even if that doesn't fix the issue, and I'm not convinced it will, swapping it out is a good idea as they wear out really fast.
