XCR Opinions

Ouch!

Sand Test = EPIC FAIL
Mud Test = EPIC FAIL

Compared to the USGI M4 (which passed all these tests with the US Army selection testing), the XCR = EPIC FAIL.

from the author comments:

Keep in mind the issue with the sand test was my fault and not a result of the design of the gun. I mixed and matched lowers and did not ensure that the retention pin fully seated in the lower. After the problem was found and the pin correctly seated, the receiveres did not seperate. Since this test, all of my uppers and lowers swap with no problems. Correctly seating the takedown pin is covered in the manual and I did not do my part as the user. The XCR is built like a tank and I trust it.

:feedTroll:
 
If you want a non restricted .223 black rifle that takes 10 round mags then the xcr is probably your only choice... I have one and think for that its a great rifle. It is maybe a little overpriced but other than that I find no issues.

It is very reliable. Mine shoots 1.5 MOA (with american eagle ammo) and I am not a good shooter. the rifles own accuracy is probably a little closer to 1 MOA.


The way I see it: If you shoot targets on a range, get an AR, if you plink stuff in the bush, get an XCR

Speaking of good non-res black rifles - Tavor
 
I just got my new XCR as well and quite like it. However, the LOP is a little short, and the plastic charging handle concerns me just a little. does anyone (hint,hint) make a drop in replacement that isn't?
Trigger is nice, much better than the other black rifles I've handled.
It is front heavy, but after handling it for a bit, you don't notice it.
All in all, I'm pretty impressed, can't wait to get the the range and test accuracy.
 
It wasn't bad. The main problem I had is that those laquered steel cases would stick to the chamber. I had to use a gas setting of 4 to get proper extraction. Even then, one out of 50 or 60 cases would stick to the chamber and fail to extract. This the one of the reasons I went to .223. The other reason is 10 round LAR Magazines. The barrel was chrome lined, I believe all XCR barrels are.

Thank you. That helps. I'll be getting a 7.62x39 conversion kit from Wolverine and time permiting, will post my thoughts on this novelty.
 
Im still amused by the loose bolt complaints. Sorry there is one cause, and its not rob arms. If your scope comes loose its not Leupolds fault, if your action comes loose on your TRG its not Sako's fault. Loose thread tolerances cause stripping, not loosening. Im sorry guys but if your tire falls off after you did your own brake job only YOU are to blame. Perhaps the tightening process is too complicated for some, for whom this applies perhaps you should stick to wearing velcro shoes and having your rifle serviced by a smith.
Bolts hold the world together, they are a great fastening device used on items seeing high stress, high vibration, high impact and massive temperature fluctuations on earth, under water and in space. 200 years there has yet to be developed or invented another more proven method of fastening things together. When bolts come loose, the installer is at fault. There are exceptions but none are related to the "bolt issues" of an xcr. Sorry, your doing it wrong. PERIOD.

That sand/mud test is also one of the dumbest things ever to be brought up, it goes to prove how desperate you have to be to trash on the xcr. That was years ago, with poor machining tolerances. While I admit you should be able to swap uppers and lowers with your eyes closed and have them function perfectly. This clearly was not the case with the rifle used in that test. Rob arms QC has advanced at an exponential rate, many people have multiple uppers and no bods is having fitment issues. That reference is about as valid as me bringing up the thousands of soldiers killed in Vietnam WHILE clearing jams of their AR's. The past is behind us, leave it there.

Well said. Teething issues wil always acompany new products. Mine runs fine other than user error(not seating mag properly),and the ####ty cprod mag that holds four rnds.
 
I see... user blaming C-Products for only 4 rounds fitting into mag... :D

Pop the bottom of that mag off and cut a link or two off of that spring and you will have a mag that holds 5...

What can I say... :)

LOL... I guess I'll go throw out my ASME/ANSI B1.2-1983 2B and 3B thread plug gauges and stop failing high tensile stress, repeated impact or vibration-environment holes that go over 3 turns on the gauge.

Some random dude on the internet says thread tolerances don't have anything to do with fasteners walking out under vibration...

Thank god that engineering problem is now solved. :rolleyes:

Honestly, you won't need it. It's just the end of the handle which is composite. The handle itself is metal.
 
claven, your such an expert on ansi specs, so lets hear your testing results on the xcr's fasteners. If your so well educated on the subject how come you had loose fasteners and I dont/havent? As I said there are exceptions but you wont find these situations here. This sounds like a case of the master mechanic losing his wheel. Time to put away the text book and turn on the brain.
 
In the and all bolts can come out under the right (or wrong) conditions... The bolts that really arent supposed to come out have cotter pins or tabs or what not.

However, I cant see the big deal about putting some locktite on the 4 bolts that supposedly loosen on the XCR.... After that, they wont come out for sure.
 
^^^^^^Exactly. everyone puts in on their bases and rings. Almost every nut and bolt I see these days had it applied from the factory and Im a mechanic so you can imagine. Lock tite was invented for a reason, and its been adopted by almost every manufacturer on the planet and used on almost every bolt for a reason. Where once upon a time bolt torque was a primary method used to keep them from loosening. (some things just dont need to be so tight) Now they can simply be snugged up sufficiently to prevent movement, locktite keeps the bolt from loosening. This saves the bolts and threaded items from being unnecessarily fatigued via repeatedly nearing its yield point.
Anyone lacking the aptitude to perform such a simple task as locktiting a few bolts is also incapable determining if their gun is even safe to fire in my opinion.
 
A question for the folks with a 7.62x39mm XCR, have you ever used LAR-15 10 round magazines and replaced the follower with a 7.62mm one?

For that matter has anyone tried feeding x39 out of a LAR-15 magazine?

Sorry to stray a bit from the original topic, but it is the make or break for buying an XCR.
 
I see this thread is still going strong... Having re-read it in its entirety, I still can't say as though there's anything that really stands out enough to persuade me to ever consider an XCR - nor does it even remotely hold a candle to the next-generation SCAR-K, ACR and ARX-160. The more I read about the XCR's "quirks" I realize it's just not something I could ever consider. I don't get a lot of shooting time as it is, and it would seem the XCR requires a lot more maintenance than what I'm typically used to. I'll stick with my AR. Happy times.
 
Matinence as in pulling out a few bolts, cleaning them and applying a compound at the same time you clean/oil your brand new rifle before shooting and never have touch them again. Ya, that's a ton of work. Some people just fall right into the anti trap, it's kind of funny. They see someone else doesn't like it so they don't either. How often do your optics, grips, accesories, sights fall off your ar's? Are those spirally cut fasteners on your guns somehow different from the ones on an xcr?
Some of you guys are prime examples of all the anti idiots out there. You capitalize and exagerate a few bad examples to front your personal opinions. I suspect some peoples bad experiences are completely fabricated lies. Why anyone would do that I don't understand but there are many pathological liars in our society and I thinks a few have found this thread to stimulate their psycological dependency of seeking attention. You know, the loud ones that are always right, know everything, need to be recognized, thier equipment is superior, they'll show you how to do it, they say "watch me" or "take a picture of me doing this". I have news for you guys... You don't win anything by trashing a product on the Internet. No one recognizes your face in public as the great gun expert, other interneters don't invite you over to watch the game. Bringing up past, rare and exagerated problems with an item or speaking on a subject you have no firsthand experience with is pathetic and welcome nowhere.

Having never owned an XCR, I'll just reiterate: "...it would seem the XCR requires a lot more maintenance". I'm certainly not going to apologize for the fact that I have limited range time and, as a result, zero tolerance for anything that's finicky, time-consuming or generally prone to breakdowns.

Some people just fall right into the anti trap, it's kind of funny. They see someone else doesn't like it so they don't either.

In fairness, I at least acknowledged that I've held one - and that the fit and finish was better than I expected. While this isn't necessarily a ringing endorsement - it's not a condemnation, either.

I'll let you know if/when something like that happens.

Simply acknowledging that the XCR has some shortcomings instead of endlessly defending any/all manner of design flaws and constantly accusing people of being "haters" may actually gain you a few converts. Incidentally, there are a lot of black rifles I also don't own; the XCR just happens to be one of them.
