Problems with a 10/22 Volquartsen hammer

[PTK]

I recently installed a Volquartsen hammer, hammer spring, etc., into my 10/22. I now have a problem of the hammer following the bolt down every 10th round or so, causing either a light strike or a double (or triple!)

What gives? Did I do something incorrectly, or should I just forget about the new hammer and parts and put the factory stuff back?

I would first try the VQ hammer with the Ruger spring. If that still gives trouble, then get a VQ sear also. I have had great success with VQ hammers & sears in three 10/22s.

+1 on the above. I had a similar problem that went away once I switched back to the original Ruger spring.

Yep use ruger spring .

Which sear are you using, factory or Volquartsen?
Sometimes VQ sears will slip...other times Ruger sears will slip. It just depends on the individual trigger housing and parts.

If using the factory springs and switching the sears around doesn't solve the problem then return the hammer for a new one.

did you oil it before 500 rounds??..

Factory sear, and no oil.

I'll try putting the Ruger hammer spring back in and see what happens. Thanks everyone!

It will raise trigger pull substantially. get the matching VQ sear. Your trigger will thank you for it..

The Volquartsen hammer and sear were made for each other IMO. I've used a couple of them in two 10/22s without any problems. A much improved trigger over stock. If you ever have to send your 10/22 to Ruger for any reason be sure to put the stock part back in before you send it.

Outside of double checking operation and installation of the hammer with the trigger group out of the gun, check the mating surfaces of the hammer and sear, the VQ hammer is shallower than the stock peice, and if the sear does not sit flat, it might bounce or slip. I stoned the factory sear, polished the faces of both surfaces and put a set screw in the sear to adjust out pre-travel against the disconnector. You can easily make a jig by drilling holes in a block of dense wood or plastic spaced the same as the pins in the trigger(use a drill press to make the holes straight) and assemble the parts on the jig (using action pins) to check operation and to make sure the surfaces match. an increased power hammerspring may also help. I have learned through trial and mag dumps to perform a simple check with any trigger work, cycle the action 5 times with your finger off the trigger, and then 5 times with the trigger held to the rear, making sure the hammer doesn't fall untill you pull the trigger (or release it and pull it). This can help check that the sear and disconnector are working ok and help with finding what parts are at fault
