I agree, I have done a lot of clean up work on my rifle. The machining is pretty bad. I re cut the crown on my barrel. My rifle shoots pretty well so maybe I was lucky. I am looking forward to more aftermarket support for this rifle.

I will share my experience with the RPR Rimfire. Mine shot horribly out of the box. 3-6 inches at 100 yards. I suspected the barrel was the issue since I could feel a definite constriction at the muzzle die to the effects of turning down a hammer forged barrel. I replaced the barrel with one an ER Shaw stainless match barrel which shrunk the groups, but only by maybe 20%. I then looked at the bedding and discovered the real problem. The rear of the receiver is supposed to be supported by two ears that protrude from the sides of the receiver channel and sit in the pockets milled into the sides of the receiver. I believe many guns like mine have tolerance stacking issues with the receiver, stock, magazine catch block, and trigger assembly housing that causes the ears in the stock to not precisely fit into the receiver pockets. After bedding the ears into the little pockets my rifle now shoots very well. The last group I shot was 5 rounds into 5/8" at 100 yards shooting prone off a bipod.
Sounds very interesting; do you have pictures of the work you did?
What kind of ammo where you using? The best group I've gotten so far at 100 yards was a 10 shot group about 1.5 in spread in 5-8 mph winds. I felt this was pretty decent considering I was using federal auto matchI will share my experience with the RPR Rimfire. Mine shot horribly out of the box. 3-6 inches at 100 yards.

The lose fit of the V-block which also houses the ejector could explain the weak ejection issues some of these rifles appear to have.I don't. It was a hail Mary done a couple nights before the match. I had some steel putty on hand so I mixed up a small amount and put a small dab in the pocket on each side of the receiver and put it together. I took it to the range the next night after work to try it out and check the zero. Unfortunately there was a storm blowing in with gusting wind so I couldn't really determine how much it helped.
Is type of rough milling work on a bolt normal? Mine shows these milling marks also. Not sure if it would affect anything, it just looks sloppy.I have yet to see any bore scope images of an RPR barrel, if the machining quality is similar to the bolt machining that could explain the issue.
This is my RAR Target in .17HMR replacement gun bolt they returned to me.
This is my RPR, it's better but IMO the machining indicates less than ideal speed, tooling, and fixturing practices.
We have a Cabela's locally, I've inspected the bolts on a few RAR's they've had in the rack. I've seen some that have exceptional machining and some not so good. None as bad as the bolt in my replacement .17hmr rifle.Is type of rough milling work on a bolt normal? Mine shows these milling marks also. Not sure if it would affect anything, it just looks sloopy.
What did you use as a spacer material?Very interesting. I found a bit of "slack" in the same place today. I have cut a couple of spacers to fit as a temporary "fix" to see if tat helps/
Just when I thought it couldn't get much worse than mine. I've never associated this caliber of machining acceptable in firearms manufacture, obviously times are changing.Is type of rough milling work on a bolt normal? Mine shows these milling marks also.

So I don’t know if this was around 1.5 inch but it was a guess. I forgot to get the tape measure out at the range. The weather was taken around 1130 am that day.

I just got a Return Authorization from Ruger...… again.
Hoping to hit the Barrel/Chassis Lottery this time.
Thanks, don't know if I deserve it, but as longtime Ruger supporter I wish they'd up their game instead of continually shooting themselves in the foot.Good luck, you deserve it.
That’s disappointing. I agree with you all, I to had to do quite a bit of polishing and some machining to get my action “Super Smooth.” It’s a shame that for a “Precision Rifle,” there is not real high quality control. They need to step up the quality to shoot with the higher priced rifles. I’m not saying they need to have 800-2000$ quality, but it would be nice to have 400+$ quality in it.I have yet to see any bore scope images of an RPR barrel, if the machining quality is similar to the bolt machining that could explain the issue.

The biggest issue IMO is they put "Precision" in the name and that creates elevated expectations. The average performance of the rifle makes it pretty obvious..... the intent behind using "Precision" was marketing, If Precision was a manufacturing objective the gun would actually be inspected and tested by qualified personnel before shipping.That’s disappointing.

Very interesting. What are your action screws torqued to?I would try a dab of bedding compound in the pockets on the sides of the receiver. There is one just in front of the bolt handle slot on the right side and one across from it on the left side. These are what locate the rear of the action, or should. If the corresponding ears on the inside of the stock aren't bearing or bearing evenly, then I believe this is the cause of poor accuracy. It certainly seemed to be the issue with mine.
What did you use to torque your action screws? A FAT wrench won’t fit, right?30 in lbs
I smoothed my bolt with diamond files like these: EZE-LAP Diamond FilesHey guys.. new to the forum.. just a quick question about this rifle.. i recieved mine the other day and upon pulling it apart i noticed that the quality of some parts are pretty average.. the 15 round mag is very loose in the well.. the bolt has left over material in the corners and orbs from machinining.. the magazine release top wings look like thay have been cut with a hack saw.. very jaggered and uneven.. the top of the trigger housing is fairly average too.. im contemplating contacting ruger and asking wtf?.. however i am reluctant to do so as i am in australia and anything that involves weapons is very costly and time consuming.. anyone else experience this?.. i was very excited to get this rifle.. and im pretty dissappointed with the quality..
Well you are giving me faith.. not the best.. (i dont men your shooting).. bit i think its acceptable for the price of the rifle.. having the option for other barrels and timney triggers is also a bonus.. ill clean mine up and give her a shot.. havent even put a round down it yet but have 6 different rounds i want to try.. how do you feel about the accuracy and the rifle in general?.. thanks for the reply..This is with SK Standard Plus at 50 yds.
Not the best by any means and I've shot worse. I've seen other's guns shoot much better, unless they are posting only "golden" targets.Well you are giving me faith.. not the best..

My V-block had casting burrs where it seated against the action which I smoothed with a Dremel tool. Also the trigger tang at the action takedown cause the action to ride high of the V-block slightly. I put piece of .040" aluminum tape on both sides of the block and that level the mating surfaces.
Are the diamonds 1” Also, can I ask where you got that target?This is with SK Standard Plus at 50 yds.
Here's the clearance test and also shows the deburred areas:You happen to have an image of what this looked like?
Diamonds are 3/4" x 9/16"Are the diamonds 1” Also, can I ask where you got that target?
So i sat down tonight in front of the tv and did a full dismantle of the bold.. wasnt really supprised to see small imprefections but it was nothing a bit of love couldnt handle.. i filed and sanded most of the imprefections away besides some or the machining tool marks as i didnt want to take to much off just smooth it out.. the firing pin base that rides the channel was rather rough so a small touch up there.. buffed what i could by hand (little ones in bed).. and cleaned her up and oiled.. put in the action and ran the bolt.. much much smoother.. i think it could do with a touch more cleaning/smoothing.. but is already an improvement.Diamonds are 3/4" x 9/16"

Can’t view your images ?Just finished testing my new Green Mountain 22" barrel thought that everyone here might be intrested in my impressions:
Ruger Precision Rimfire Factory Original barrel:
This example is pretty much what occurred with every ammunition brand I tested. The flyers occurred randomly sometime less with with more expensive ammunition but they were always there.
Cleaning the new Green Mountain 22" barrel barrel for the first time:
I really wasn't supprised to see these patches when I cleaned the barrel before taking it out for the first time. The manufacturing process is durty work.
I shot 100 "seasoning rounds" per the Green Mountain's instructions that were included with the barrel.
I knew from the first shots on paper that this barrel was a definate improvement.
New Green Mountain 22" barrel with Ruger Factory thread protector installed:
The target above was shot with the Ruger Factory thread protector installed on the GM barrel.
New Green Mountain 22" barrel with ebay muzzle device installed:
I ordered a cheep muzzle device from an ebay vendor because I read here that the factory barrel performed better without the factory supplied thread protector. This target is shot with the muzzle device and the barrel "seasoned" with 25 rounds.
All targets were shot at 50 yards using CCI Standard Velocity ammunition. The winds were light on both occasions 3 to 5 MPH.
Take away from the barrel swap out. One, I love the GM barrel! Two, I'm not an expert shooter by any means I've only been doing this for about a year. I'm sure the flyers on the GM targets are my fault. I either rushed the shot or jerked the trigger. This barrel in my opinion delivers the consistency that you need when target shooting. Finally, I love the longer profile that the 22" barrel provides:
That about covers it. Happy shooting;
