I have Timney triggers in the .308 and 5.56 versions of the Ruger Precision Rifle in my safe.  I like them, so when I got the Ruger Precision Rimfire .22LR version I figured I'd put a Timney in it too.  The RPRimfire was said to have the same Precision Trigger that the larger rifles do.  It does, but it sort of doesn't.  The RPRimfire uses the same Precision Trigger module that the larger RPRifles use, except that there is some additional machining to the module to make it fit the smaller chassis of the Rimfire.  The overall dimensions are the same, and all that's required is some material removal from the Timney.  No mods to the rifle are necessary, it's 100% reversible.  I completed this yesterday and it works just fine.  Took about 2 hours with a Dremel and needle files, requiring several assembly/disassembly cycles for tweaking.  It won't take you as long, I hope.  As with the install of the Timney in the larger RPRs, the location of the trigger makes a difference in the operation of the safety.  Be prepared to tweak the trigger into position for easy movement of the safety.  Too far forward or aft and the safety will be hard to move.

Cool but I can't see your picture.

Fixt?

Still no picture for me.

One last time and then I'm trying a forum that lets you upload photos.  Try this:

Or this

That worked.

Nice mod!

Update 1 (less important): The modded RPR trigger has over 1200 rds on it now with zero problems.  It works great, and it's still an item of interest to others at the range.

Update 2 (more important): Timney is in Beta testing for their RPRimfire trigger.  I know this because, back when I originally posted this thread, I also sent Timney Triggers the photos of the mods I made of the RPR Timney trigger into a fit for the RPRimfire and its install into my RPRimfire and they responded with interest and an indication that they were in late design/early testing of their own design.  Then, the other day, I got an email from them asking if I'd like to be a Beta tester for their RPRimfire trigger design (HELLS YEAH!), and so they sent me one to try out.  I will post some pics of the install and my impressions of it once I've provided them to Timney, since they were kind enough to provide me this opportunity.

As good as the factory RPR triggers are, I think the Timneys are a worthwhile install for the improvement in trigger response and reduced pull.  I really like my modded Timney RPR trigger in the RPRimfire, and I expect the Beta test 'real deal' to be as good or better.

Was your Ruger trigger pack a bugger to get out? Mine looks like it isn’t going to come out with out some mods to get it out

@trashcan101 any update?

Anxiously awaiting the test results. I have only had the opportunity to fire about 10 rounds thru mine and the trigger feels ok.

I have nothing bad to say about Timney triggers. However...  the stock RPR trigger is really good. Especially when you remove the triggger return spring, mine breaks cleanly at just under a pound.

I did the removal of the return spring in mine. Trigger is good but sometimes does not reset.

Replace the return spring with a clicky pen spring. My trigger breaks consistently at 1.5lb with no reset issues.

With the stock return spring, I couldn't get below 3lb...

I don't know if the Ruger American Target has the same trigger pack or not, but I believe the action is mostly the same other than a pressed vs threaded receiver for barrel fit (I think) but the pen spring mod in my trigger put it dead on 2lbs, and still resets nicely. I also tweaked the drop safety lever back slightly so it's not so noticeable when you're squeezing the trigger.

Good job on the Timney install!
