MK II accutrigger trouble

[Somerset Bar]

Just wondering if anyone has a tip before I just blindly disassemble/reassemble the trigger group.

Trigger is set at approx ~5lbs according to my gauge, I'm second owner (but know the first owner and history).

Basically, it has a tendency to not completely reset the trigger at random times, the blade stays locked, I have to re-#### to release the blade. I've got three of these rifles, two of them with triggers set a bit lower, and never had this trouble. I have 2 other savage rifles that I've swapped out the accutriggers for timney, but tough to justify that $$ on a rimfire. Just looking to get the trigger working, but not 100% sure which part might be acting up. Any tips or ideas would be appreciated

The symptom sounds like the problem is too little sear engagement, as in the sear is slipping when you first #### the bolt but being caught by the accu-blade. Thing is, sear engagement is not adjustable on these triggers so this would not make sense unless the previous owner stoned the sear, trying to reduce creep. That leads me to the next possibility which is a dirty/gummed up trigger group. You'll see if it's clean or not when you break it down, so clean it up really well, coat with lighter fluid and allow to dry before re-assembly.

Will take a good look when I tear it down tomorrow, maybe it's something that simple

I sold my MKII a year ago, but before that I had taken these photos to help someone with an apparent safety issue. It demonstrates how the accu-trigger works, if the sear slips or you pull the trigger but not the accu-blade, the blade catches the sear, preventing the firing pin from dropping, and also locks up the mechanism so that you must re-#### the rifle before it can actually fire. It will only fire if the accu-blade is depressed to clear it from the sear, and then the trigger is pulled to release the sear. You can see all of this once you remove the barreled action from the stock through the window in the trigger mechanism. I'd suggest before you pull apart the trigger, to just dry-fire and cycle the action with the stock removed and observe the sear area through the trigger group window. This will show you what is going on when the trigger malfunctions. If the trigger is gummed up, the sear might not re-set to it's ledge sometimes. Or, you might see the sear slipping off the ledge when the malfunction occurs (still could be dirty and not able to re-set far enough up on the ledge). If cleaning the trigger group doesn't work, given that the trigger isn't adjustable for sear engagement, it might call for some replacement parts from Savage. Good luck.
