This isn't a REGULAR problem. It's to point out a problem that few have reported. Many of us, myself included, are approaching 10k rounds with absolutely zero failures OR problems of ANY kind. I went nearly 4000 rounds without cleaning, again, zero problems. And it was still 10x's cleaner than my AR's with 1000 rounds.
Agreed, I am on my second XCR and havent seen any issue close to this, even with crappy Silverbear Zinc. My current XCR is around 3000 rounds since I got it a couple of months back, and my first was around 10k.
Probably between 8 and 10 K rounds and the only problem I had was a broken firing pin. They sent out a new bolt and carrier within a few days. Even with the broken firing pin it still shot but I happened to catch it while cleaning the gun.
I've never had anything loosen and I haven't loctited anything. I do make a habit of checking things every other range day or so and even doing that it still takes less time to clean than any other gun. I look at it like preventive maintenance on the car--changing the oil, checking the lugs, rotating tires, etc.
It is my go to gun and has been for two plus years now.
So I took my NEW rifle to the range today, and most of the primers ended up looking like the casing on the right from the post way back. Is the back-flow of the primer normal to some degree? I was shooting Remington UMC stuff.
I got thru 80 rounds, with one mag into a ragged 2" hole at 25yrds using my rimfire optic that was not sighted in! Sure kicks a little on the #4 setting. Feels nice with the gas OFF , then I could inspect the brass without digging in the weeds.
It saddens me that I have this issue with my rifle... Rob originally posted this five years ago, yet here we are in 2013 and they are still shipping out rifles that don't function properly. The QC at RobArms is worse than any other I have ever seen including Chinese manufacturers. Considering that if I were to send this in it would take 6+ months to get back... I'm going to attempt the ghetto fix on my own. Wish me luck.
I have the same problem with my 556 kit. Getting pierced primers. Mine also came with a tight chamber. Gun basically would not function at all. Bought a 762x39 kit and its been flawless after 300 rounds other than magazines of course. Guessing our rifles were rushed and or because we had to basically harass him to get them and he sent out some half ass rifles without checking for quality control. I'm going with the latter due to sandy hook happening the same week we got them.
It does suck and I understand him being upset cause I'm having the same problems with mine. Having to wait 9 months then the possibility of having to wait another 9 months is terrible. Even if one did not have to wait for the rifle but had to wait a unknown time for a QC issue is still terrible.
I'll add in that I have read the "quick fixes" that one can do. Such as bust out the dremel for the punched primers and a scotch pad for the chamber. That awesome if they work and I'm glad I know about them. It's just that it still bites that I have to do these things in the first place.
As we all know these issues happen in every industry. It just seems worse when its your beloved firearm.
I had to send in my $1600 ASUS laptop in for repairs and in the process of trying to get a hold of the costumer service I ended up contacting a scam company claiming to be ASUS. They charged me $200 for repairs even though it was still under the one year. Of course this put me into a rage. In the end I figured it out and everything is fine now. The only thing is if ASUS put the customer service number on the website for "American Laptops" I would have never had to deal with all the BS.
Now if Rob starts charging like the scam company then I'll get raged.
P.S. If someone from SLC want to be an emissary and have my bunk parts mailed to them so they could go knock on Rob's door so I could get a faster turn around I'm always looking.
I have pierced primers (well both actually)... The firing pin hole doesn't seem to be too edgy, and I am worried about hitting it with a dremel. Most of the pierced primers are from hand loads, but it will pierce mil-spec primers from factory loads from time to time. Some primers flow back and instead of there being a crater, the primer sticks out a good 2-4 mm. The scariest is the rounds that blow out the primers completely. I have found a blown primer in a P-Mag, one lodged in the barrel extension and so on (I have a lot of reloading under my belt, so I am not a noob at it). It definitely impacts the functionality of the rifle. The failures come in the form of FTE, double feeding and the bolt not closing completely.
To top all of the primer issues off, like Arcwolf said, I am about 95% sure I have a tight chamber in a barrel that I didn't even order. When I placed my order, I requested the 1/9 twist but got a 1/7 instead. I refuse to send it back to Rob because I am not sure I will ever get it back. I'd rather deal with not being able to shoot half the ammo I have stocked up than send it back...
So, to sum up my XCR-L experience after owning it for 6 months and going out to shoot many times: VERY POOR -- I know that I can take steps to get the poorly built rifle working like it should out of the box, but I just feel taken advantage of and alone in the woods about it... There are very limited options for getting the damn thing to run correctly, because I can't count on Rob to fix it, sell me parts, or talk to me on the phone about ways to troubleshoot. I have to rely on my research, online buying skills, and doing the work on my own (I can handle a tool, but I am no gunsmith by any means).
I will try using the dremel on the firing pin hole, and a scotch brite pad on my chamber, but I am not holding much faith that it will work 100% afterward. If I am not mistaken, my barrel is chrome-lined and by using a scotch brite, I won't be able to smooth it out say as much as a stainless barrel, or I might chip off the chrome. That is the reason I am apprehensive about trying that out. After talking to a great gunsmith, he seemed to think that using a scotch brite pad wouldn't get me anywhere.
Sean and Merlin, have you guys tried dremeling the firing pin hole or using a scotch brite pad on the chamber? Can you tell me with any certainty whether or not my barrel is chrome-lined (its an 8XXX model)?
I don't remember seeing people use Scotch Brite pads but then again I am old and could be forgetting. Most have used the appropriate caliber honing brush from Brush Research.
You can use their honing oil or Mobil 1 or similar....
I never had the firing pin hole issue.....I'm guessing you need to chamfer the hole itself, but I have no idea how much or the proper process. There should be threads here on the site to tell you how.
Sorry to hear about your experience with your XCR-L.....unfortunately, I had the same problems and it took a good 9+ months to get it sorted. Looking back, it was worth the trouble, but I understand your frustration.
Oh, and your bbl IS chrome lined. The XCR-M has some SS bbls....but chrome has recently become available. The L has always been chrome lined. Oh, and don't worry about the lining....the hone will just polish the surface, take our irregularities, etc....but my understanding is it likely won't require you to cut through the surface coating of the chrome.
