I have a ruger sr-556 and I am finding metal shavings in my trigger assembly. I did replace the stock trigger with a Chip McCormick and like the feeling, however, I think the bolt is causing some metal to deteriorate. Are bolt ar’s common for this, or is something wrong?
Also, I have a aimpoint m3, I plan to put a 3x magnifier on the rifle, but I do not have one now. Should I move it towards the end of the rifle or keep it close to the back of the upper? I do not want to have to re-sight the rifle with or without the magnifier. Also, is the twist off or spring to the right of the scope a better mount? I like the advantages of both, but hate to get that magnifier snagged on a something when I am chasing zombies.
can you take and post a pic of the shavings? are they silvery or coppery? are you finding gouges/high wear marks on any parts, like the inside of the upper receiver?
as to the optic… most guys prefer to keep their field of view as open as possible, and stick their RDSs as far forward on the receiver as possible. with a good cantilever mount, you should have plenty of room for the magnifier.
I already cleaned it, so the shavings are gone. But it does look like they are coming from the buffer spring area. It is shaved down. I went to Rugers website and it seems that they think this is normal. How the hell is metal shavings normal? It is like Ford telling me my new diesel will experience a new break in period with metal and oil on the ground.
If it’s shaving from the bottom front edge of the buffer tube it is most likely carrier tilt. There have been many discussions on the different sites and this one too concerning this issue. Some of the SR556’s suffer from it and some don’t. I would definitely send it back to Ruger, the couple of cases I’ve seen do not get any better, the condition continues to deteriorate.
I sent an email to Ruger and they basiclly told me to go away in a nice way. Are they serious? They said that this is normal and there is no concern at all. Zombies are on the way, what will I do if my AR fails me?
were i to go piston, i’d probably ramp and lap the bottom side of the rear of the carrier. i have to wonder why the HELL piston manfers aren’t already doing this.
the other option, which might not be an option at all, as i have no clue as to availableness, is Seth Harness’s anti-tilt buffer… Seth is a member here, perhaps PM him and see what the staytus is on that.
Just because something normally happens to a particular rifle / design does not mean that it is a good thing. As mentioned carrier tilt in the piston style Ruger causes excessive wear especially around the receiver extension. While this may be somewhat of a normal occurrence in the Ruger SR556, that does not mean it is a good thing. Too bad Ruger has this attitude, but I am not surprised.
OK, sorry but that is just an asinine answer. Does absolutely no help and makes you look like a think you know it all jerk. :mad:
I did look around, and many of the magazines I subscribe to say it is a great rifle, so do many of the dealers in this area. They can not keep them in stock. So I am sorry I did not call and ask your expert opinion on the matter, but I will sure to be sure next time I buy anything, including condoms, I will ask for your opinion and see how YOUR personal feelings are. :rolleyes:
Besides, the the Thurston county sheriff here in Washington bought 5 of them, maybe you should call them and give them your opinion also.
Sorry, but people like you really piss me off, if you do not have anything of value to add, done even reply.
while what E53001 was a little short on help, i have to somewhat agree.
Magazines are out to make money and sell more copies, they will say whatever brings in money. in that same mag that gave the SR556 a good review i bet there was a few full page ads for Ruger.
Ruger buys a few full page ads…mag writes a good review. i scratch your back you scratch mine.
dealers are also out to make money, they are not the end all in firearm knowledge.
neither is the sheriffs office, remember the SR556’s we’re probably bought by some pencil neck paper pusher, not a firearms expert.
the fact remains gas pistons have a tendency to have carrier tilt.
i suggest getting the anti tilt carrier posted in this thread.
indeed- gun magazines are NOTORIOUS for putting out bad information and shitty (totally skewed toward the positive) reviews.
furthermore, LEAs are no more likely than anyone else to know what the hell they’re doing when it comes to guns. you’d think otherwise, but they’re subject to the same misinformation as everyone else.
as the above OP stated, piston guns are very well known for having this problem, and as E5 suggested, if you’d done a little more research, you’d have known this ahead of time. it’s their best known drawback, afterall.
but we’re here to help. dont get bent out of shape when somebody flicks you shit- you gotta roll with the punches and take the good information from wherever it comes from, whether somebody’s an asshole about it or not.
ramp/lap, or get an anti-tilt carrier- those are your options, and you got that information right here on m4c- see, we’re already 20 times more helpful than any gun magazine or cop shop around.
aside from that, you could probably sell for a small loss, and get a BCM.
It could be the carrier tilt issue, but it also could be cam pin drag in your upper receiver on the left side. Take a look. Most (if not all) piston ARs have this problem too.
And I wouldn’t have bought the Ruger either. Sorry.
Before anyone else has their feelings hurt, please listen to what bkb0000 said. Gun rags are there to show off products. Magazines sell and make money, manufacturers help pay for ads, etc…etc…
Many of those writing the articles have little real world experience and most of the time they have not extensively tested the products they have.
This is why it is important to take what the gun rags print with a grain of salt and try and get opinions of those who have expereince. As for whether or not the Thurston County S.O bought five of them, that means nothing. Most police officers will be the first to tell you that they are not gun guys.
Having said that your simpliest route to a potential fix is to contact Seth Harness and get an anti-tilt buffer. Or you can contact Ruger and inform them that you are not happy and that you want to return the weapon.
