You should have fired it in the stock condition to make that determination. You should also have cleaned and degreased then properly lubed the gun.

 

So, I fired it plenty in stock, and never noticed anything. It's also why I asked if this was normal and I just hadn't noticed before because I hadn't had this particular problem before installing the kit. If I hadn't had the problem, why would I look for issues when it was working fine?

I clean the weapon after each trip to the range.

Thanks for your assumptions!

 

Good luck, you're going to need it.

 

cool. thanks for the help.

 

Well if the gun was functioning perfectly BEFORE you dropped in the after market stuff, it should do so again when you return it to stock configuration.

If it does function perfectly when stock?
Either you didn’t quite assemble the after market stuff properly (doubtful) or there is a fitment issue with the after market part(s).

If it still doesn’t function properly after you return it to stock config, then you MAY have tweaked something during your upgrade, and you will have to identify that thru careful inspection and testing.

 

Yeah. This is most likely what I'll have to do. tbh, i was hoping someone had experienced this with the kit which i why I asked here before taking it all apart again.
sometimes there ARE easy answers; this one may not be. But you don't know unless you ask.

Wow, nice welcome, Richard.


CW, welcome to the forum. @Scswolf has given you good advice.

 

Today I noticed there's a significant "pause" when the bolt is about 1/2 way back, before going to full spring compression and then returning to closed.

It only happens when OPENING the bolt. It closes in one smooth motion.

That's very normal when you cycle the bolt with the hammer already cocked. It's the bolt hitting the face of the hammer before pushing it beyond cocked to "over-cocked".

Welcome to the forum!

There's nothing in the accurizing kit that should affect the ejection of spent rounds. It's probably just still breaking in. I start a new pistol off with the bolt and recoil spring fairly wet with oil and stick to HV ammo for the first 500 or so rounds. If it's still acting up at that point, I'll change out the extractor with a better one from Volquartsen or Power Custom.

After break-in, I reduce the bolt oil but still keep the recoil spring a little wet. One or two drops of RemOil on the guide rod keeps the bolt cycling very smooth.

 

I did the accurizing kit also with no issues. Did you perhaps do the complete competition kit?? That one has more parts.

I wasn't sure I understood what you were saying. So, I pulled the bolt back, noticed the behavior I mentioned. Then I dry-fired the weapon. Then pulled the bolt back.
It moved back in one smooth motion with no pause. Now I get it! I didn't think to pay attention to the pull directly after a dry-fire until your post.

Thank you very much for your reply! I'm glad I didn't delete my account after the first person who replied.

Are you saying the KIT needs breaking in or my pistol? I put maybe 1500 plinking rounds through. I needed the Volquartsen kit once I started shooting bullseye. So I'm pretty sure the pistol was broken in when I installed the kit.

Thank you again for explaining the issue I was having, and you don't know how glad I am I do not have to take the gun apart this weekend.

IMHO………of course

 

Howdy neighbor ... just west of Charleston here. When I picked up a new Ruger MK-IV Competition Model I wanted to make it something special and started to pick up a few things for it. I started with a Ruger scope base, a C-More RDS, TK Bolt Racker and a Volquartsen kit. But at the same time I was in the middle of another project so I sent my MK-IV and the Kit to Volquartsen to have them do the install. It came back with a crisp, two and half pound trigger. Perfect.

It's become my favorite range toy and it runs like a Rolex. Shortly after I got it back I was able to get a couple of great deals on some ammo ... I picked up 6000 rds of CCI-Pistol Match and 3000 rds of Lapua Pistol King. It never gets left at home on range day.

 

So, in the first competition I shot after installing the kit, my score increased by 90 points - I attribute all of it to a lighter trigger pull. It was in my 2nd competition that I had a failure to eject - the bolt closed on the shell as it was being ejected.

Shooting CCI standard velocity in a 22/45 which other than those two rounds and two light strikes, the gun's been great!

I normally shoot minimags but have been using a lot of lower grade ammo recently which is much waxier. I've noticed that cleaning the mags is as important as cleaning the gun for good reliability cycling. Give it a try.

 

I installed the Volquarsten Trigger upgrade and now know how not to install it over many, many attempts. Finally got it installed and never had any issues with it. The issue may be spring related on your Ruger bolt. If you shoot sub sonic, it may need a slightly weaker spring. If you shoot high velocity, it may need a stronger spring. Also, the Ruger hammer might break if stressed too much. I purchased the spring kit from Volquarsten and eventually put in the Volquarsten Bolt. I have never had any issues with the mods. Good luck isolating your issue.

 

The allen screw on the top behind the port can be run in far enough to drag on the internal bolt return spring. Been there and done it.

 

Sorry, this kind of a late welcome to the forum from Iowa. I hope you are getting your MKIV running well by now. I don't have experience with the MKIV pistol, mine are both MKII series, but I have done the Volquartsen accuracy kit install on both and it makes them a nice target pistol. Hope to hear more updates from you.

 

One issue that I found with my MkIV when I was having seemingly endless ejection issues was the ejector blade had come loose and was able to move left and right a little. Ended up with inconsistent ejection and stove piped cases. Once my gunsmith recognised the issue and tightened up the mounting rivet no more issues…always worth a check! 🙂👍
