Trigger on Mark III

Bullseye, is it your recommendation to install the Volquartsen target trigger, as well as the sear, in the Mark III target model? Or, is the Ruger 512 target trigger good enough?

Both triggers are good enough when they are on equal footing. This means that a factory target trigger needs to have a pretravel screw modification added to it. The VQ target trigger already has both pre and over travel screws installed from the manufacturer.

One precautionary note about adding a pretravel screw to a Mark III trigger, there is a possibility of the trigger's spur on the back interfering with the removal of a magazine.

This condition may happen when a pretravel screw adjusts the trigger closer to engaged, and this puts the spur under where the upper magazine window bump is located, causing interference with the insertion and removal of the mag. To prevent the interference one must remove the Mark III trigger spur with a file. Removing it will only effect the forced seating of a magazine if it was not fully locked in place. VQ Mark III target triggers already have the spur feature removed.

One benefit to using the VQ trigger is the externally accessible pretravel screw. By having this feature the VQ target trigger greatly simplifies the pretravel screw adjustment process. The only drawback to this screw is many of the manufacturer supplied screws are too short. This situation requires the owner to contact VQ for a longer screw, which they will supply upon request.

In either case, adding the VQ target sear is the easiest and best way to lighten and smooth out the trigger pull.

Hope this helps.

Ordered the trigger and sear. Hope the screw is long enough!

Three of three that I ordered were long enough. Get some loctite to keep the screws from moving.

The Blue loctite?

The Blue Locktite is the light strength (#242). It is not in a blue container. The liquid thread locking sealant has a blue color to it and therefore the nickname "Blue". The blue is more than sufficient to hold a pretravel screw fast and keep it from walking.
