Ruger PC Carbine

Mine hasn't missed a beat yet, but only 100 rounds through it. Been running 115 blazers and 147 dirty birds. So far I'm impressed glad I got rid of my jrc and bought the ruger, just wish I would of had the patients to wait for the new model.
 
So is anyone having stove pipe issues with these or is it just me?

I find this gun is so fouled up after 100 rounds it has to come apart and get scrubbed out to function properly again. The bolt and chamber are just coated in a layer of hard carbon. I know blow backs are dirty but even the cases are coming out black on 2/3 the outside of the case after 100 rounds.

The brass is so chewed up ejecting out of this thing when its fouled its about 50% scrap.

Same results with pmc and umc ammo, i'm running glock factory mags

I had mine out last night and did have a two stoppages until I put some lube on the bolt then it was 100%. This was with my 124 gr. CamPro plated RN reloads with Titegroup.

BTW mine ran fine with KCI .40 mag as well as Magpul 9mm mags.
 
Sone of the "necks" are coming out crunched and ragged once the gun is fouled, once cleaned its good to go again.

I fired 170 rounds last range trip and even with more oil after 100 ish rounds it was a battle with 1 or 2 stove pipes a mag.

Other then this issue i love the gun, no problems putting 124 pmc's on a 6 inch gong at 200m

Jeez it shouldn't be crushing the necks...
My brass is totally filthy, blackened after coming out of this gun. The blowback definitely fouls the exterior of the cases.
I haven't cleaned it yet, about 300rds in.
I'm going to see how dirty it'll get before I have a stoppage, then clean and oil it.
Kinda my modus operandi with most of my guns that aren't shooting corrosive ammunition.
 
Lordevilpepper Would you post a pic of your gun and the crushed cases. Might help. I don't know a case could be crushed and still eject normally. Just curious.

Take Care

A bunch of pages back I reported that around 500-700 rounds I was getting stoppages. Stove pipes and jams. Turns out the three barrel trunnion screws were slowly backing out. I thought it was just dirty. Once I found that out and used locktite on them no more issues.
 
I too found almost everything was loose when I did my first teardown on both my PCs. Loctite is pretty much essential with this gun. I even lost the front sight at one point...
 
Not just guns for this problem, all manner of things which vibrate. I work a lot with doublebasses and one of the more common problems is buzzing, which can emanate from any number of sources such as opened seams (seasonal shrinkage related), loose interior repairs, strings running into irregularities on the fingerboard etc. I have a mental checklist I run through whenever I'm asked to cure a buzz and right at the top of the list is loose screws on accessories, especially the tuners. Retaining screws going through brass into wood come loose surprisingly quickly. Doesn't matter how tightly they were installed, within a year or two of playing they can back out a full turn or more, allowing the thing they were holding down to vibrate against the wood. Same for the retaining bolts on tuner gears - this is metal-on-metal, a gear wheel with a square hole going onto the square end of the tuner shaft around which the string wraps. I've seen these backed out several turns, almost to the point of flying off the instrument, with the gear wheel flopping around and the player blissfully unaware of the impending explosion.

A dab of Loc-tite works wonders on those. But for the screws going into wood it's not useful. There I use a dab of normal PVA, or carpenter's glue. The screws will still unscrew when necessary, but the slight improvement in grab offered with the glue makes for enough friction that they won't back out for a lot more years, and slightly toughens the wood in the hole such that there's less risk of stripping when someone tightens the screws.

Seems fairly obvious that a gun will be if anything more prone to things coming loose. Scope mounts, stock screws, anything bolted together should eventually come loose with enough vibration cycles. Same with bicycles. When I was a mechanic in the first half of the 1980's one of the most common problems was bikes basically disassembling themselves, as their owners didn't seem to grasp that bumping down the road created a perfect set of vibrations with which to loosen practically every part on the machine. Seems to me an odd sort of mindset, that loosening bolts is a defect. It's part of how machines work. A basic function really. Screws can unscrew, and they will, if the machine is not left static. A gun left in the safe won't loosen up. A gun fired often will. So take measures to prevent it, and check screws regularly even if there's Loc-tite on them. Murphy's Law will almost certainly bite you if you fail to maintain your machines, and in my experience those failures will come when you least want them to happen.
