LRP-07 inconsistent accuracy

You never marked your scope with??? Ooo a pencil or something!
You must be on meth. Sounds smart dont it! See i can do what they do be a pussy cop on something.
Geez...

OP, I can't see the pictures due to my IP, but I hope the slippage is the source of your problems and not the rifle. Hopefully you can regain your thread as well. Common courtesy is an uncommon virtue around here.

All that "money" and your rocking crappy wall paper with linoleum in what looks like a manufactured home roof line? Plus most of those 1/2 moa or under groups are 3 shot groups, not 5 and all conveniently by themselves without other groups around them and I highly doubt they came out of that AR but more likely out of that Surgeon....

Who said its my home? Those groups r from a savage 12 LRP 6.5 creedmoor!
I don't give rats. Ass about 5 shot groups.
 
Wait, wait, wait...I hate that this has nothing to do with OP's issue, but I am stuck on LV's first picture where the SD and ES both state "0". Holy shit. That is impressive!!! I just thought they'd fly through the same hole with those numbers. It looks like your Les Baer shoots great, it should, it's a great rifle. But to go and make an overgeneralized statement about JP rifles was not copacetic. JP makes hyper accurate gas guns too. We don't even know if it's OP's rifle, and with the recent issue he found, it appears to be his scope mount. So just chill out. You got some excellent stuff man, go shoot it.

Ok, back to issue...

Good catch, timelinex. I don't know if I would have caught that as quick as you apparently did. It definitely looks like there was "sliding" or slippage with the scope in those rings. Please give us an update once you try a different setup.

After taking off the rings, its extremely apparent under there that they were sliding. They slid a good quarter inch! I called the manufacturer of ARC rings today and he reassured me that 50 in/lb is where it should be vs the 40 in/lb that I had it at. So I cleaned all parts with alcohol, put some loctite on the screw and clamped it down to 50 in/lb. I made sure to put pencil marks everywhere, so if it slides at all, I'll know. If it still slides, I'll send these back to the manufacturer and get different rings.

I'm going to the range tomorrow, so I'll try to give an update then....

Looking forward to see how it does. I have a feeling you found the problem and hope it groups even better then it did on your good days.

Good luck timelinixl
 
This thread is a fucking travesty. The 105k Hide strikes again...

OP, contact JP, nobody is going to know their rifle better than them. Hopefully you can send it in to either get it repaired if necessary, or a clean bill of health to rule out it being the problem. ANY manufacturer's firearms can have issues, even the top tier. I don't care who made it, any machine can and will break.

Typically, provided you are being consistent with equipment and setup, it's not going to be a marksmanship issue if you are able to produce several good groups on most days, and fall to shit others with only the one rifle. Yes, large frame ARs are a different animal, but this sounds like an equipment issue if he is being consistent otherwise.

My assumptions are these: You know what you're doing on your loads, you're using the same position and equipment each outing, and you are a skilled precision shooter in general.

I would start with a scope other than the PST. Let's face it, they've had issues. Following that, I would use some different factory loads. Get your hands on some from Copper Creek or Southwest, or even step up to premium loads from Cor-Bon, Applied Ballistics, etc. Next I would have other shooters test fire it and you bench rest it to remove you and potential fundamentals issues from the equation. Moving on from there, contact JP for diagnosing a possible issue with the rifle. I would not go tinkering around with it myself voiding the warranty, that's for those of us that build our own rifles.

Everyone else that are participating in the internet tough guy shit needs to sit the fuck down and let the OP have his thread back.


Yea this thread needs to get back on track
 
OK, so went to the range today and it didn’t help at all….

lrp_zpse2a122e9.jpg

Started off with a fouler, then group 1 and 2 were unsuppressed FGMM. Group 3 was my reloads unsupressed. Then I put on a suppressor and shot a fouler. Group 4 and 5 were suppressed FGMM, group 6 was suppressed reload ( I pulled one shot ½ inch to the left, I called it before even looking at the target and that’s exactly where it went). Group 7 and 8 are suppressed FGMM. Then groups 9 and 10 are unsuppressed FGMM (forgot to put turrets back down to unsupp zero on group 9). Some of those are 3 shots and some 5 shots.

Long story shot, groups 1,2,5,6,7 and 9 where decent enough, but 3,4,8,10 were horrible. As you can see, its all over the place. Some spectacular groups, some decent, and some worse than Ive ever shot at 100 yards with any other rifle.

I was shooting solid the entire time. I’m straight behind the rifle, good NPA, good trigger, good sight picture and I didn’t push any bad shots. Only one shot the entire time did I accidently move my finger a little to jerk the rifle left a little and that was in group 6, where I called the ½ inch miss before even seeing the target. Otherwise the rifle felt controlled and stable the entire time and I never lift my cheek off the stock mid group. The scope did not slide in rings, so its not that.

I can try a new scope and rings, but if its not sliding I don’t know how it will help. I’ve shot 400+ rounds already and this is just ridiculous. I have shot rifles that are just bad shooters, and its nothing like that. All the groups generally hoover around the average of how well a rifle shoots. Out of the 40 shots here, it averaged .8moa with the lowest being under a tenth an the highest being a 1.5moa. Thats just not right.

If anyone is a proficient semi auto shooter in the phoenix area, I would be grateful to meet up somewhere and you can try it out. I don’t know what to do anymore…

That's what my ctr02 did!!!!! One day 1/4" next day 1"
Ben said i highly doubt its the rifle, but ship it to us we will take it to the range and c.
I sold it....fixed that problem.
get your money back. And have LBC build you one and never. Look back
 
I would send the rifle to JP and have him look it over.

Agree, at least give JP a change to look at it first. They are good company and I am sure they will not let you down. I used to have APA build AR308 that will shoot .220" without the suppressor and 1" with suppressor. We found out later on that the quick detach mount caused the group to opened up, APA said it was a little vibration problem right before the bullet leave the suppressor that created some " Whipping".
