Rimfire Accutrigger Slipping? Make It Set!

[Josh Smith]

Hello,

The Savage rimfire Accutrigger is nice.

However, it does have its flaws. Mine started slipping when I would close the bolt. This got frustrating when using it to hunt.

My solution was to recut the sear, and, while I was at it, make it a set type of trigger!

I cut a new engagement surface on the sear above the stock engagement surface, which has worn out. This will allow the bolt to be worked hard, and the minimum pull for this shelf is about 2#, though I do not recommend going below 5#.

I then adjusted the safety so that, when the trigger is pulled with the safety on, the sear drops to an intermediate position between the two engagement surfaces. This keeps it from dropping on the original rest and ruining the surfaces (which you should have resurfaced).

The final position for the set trigger can be taken down to 12 ounces, though I do prefer no less than 2#. You lower it by disengaging the trigger.

The rifle can be fired from either engagement surface. A fly is not required as the two surfaces are close enough together that the momentum of the trigger carries it past the secondary engagement surface if you shoot off the primary.

Of course, if you decide to do this, you do it at your own risk!

Accutriggers

.
The biggest reason that the Savage Accu-trigger slips when the bolt is closed is because someone has backed it off too much in trying to lighten the trigger pull. There needs to be a reasonable amount of pressure for the sear and trigger to engage positively.

Quite frankly, I do not favor your modification. It does not provide enough engagement of the sear and a good bump could accidentally fire the rifle. Have you tried a drop test to see if it will hold?

The second part that I do not like is that these critical parts are not really made of good solid steel, but rathered fine powdered metal formed under pressure and they have a light surface hardening on them. When you file through this hard thin layer, you are into a soft part of the metal, and excessive wear will result. You can already see in your pictures where the sear is starting to "burr" out and wear a bit.

You have reduced the actual contact area between the sear and the trigger to a very small area. As such, the pressure of the firing pin spring pushing against this small area will wear it quickly, and it will create a dangerous condition that could result in an accidental discharge.

You state that you recut the trigger notch because it was "worn out." I would suspect that the wearing out was caused by trying to file or reduce the area where the sear and firing pin contact, and subsequently the sintered metal, being softer, wore out quite fast because the hardening layer was gone.

i have several accutriggers and have no problems with any of them, i back the out so the screw does is flush to the edge of the metal and than 2 full turns back in so it sit inside the spring, never had a problem and work my bolt very aggresively.

Hello,

The metal seemed very soft on mine, like it wasn't heat treated well.

The burrs you see on mine are where I had yet to clean up.

Everything was case hardened afterward, but has held up for a couple years. Yes, it does pass the drop test.

It is a very interesting mod.
