New 6.8 XCR

[hitman]

I picked up a new Robinson Armament and shot it today. 1 st- it does shoot very well. Seems to lke the SSA 85 TSX laod. That groups right under an inch at a 100 yds. Shoots the 115 OTM load almost as well. But, I had several malfunctions. Its like the trigger does not reset every time. I can cycle it by hand (unloaded) and pull the trigger it drops the hammer, cycle it again and try to pull the trigger and nothing. I mean the hammer does not drop .... its like the trigger does not reset. It happened about 4 times during live fire then I began to handle cycle it empty and it did the same thing some more. What do you guys think???

Congrats on the XCR. Do a basic field strip and see if anything obvious is getting in the way of the hammer or trigger. I'm not an XCR expert, but I'd take a look at the mechanisms and see if anything looks out of place. A call to Robinson would be my next place to go.

Robinson Arms has a forum off their website. You might post this question there also. Let us know what you find out.

What was the gas setting? If it was on 1 or 2, you might want to turn it up to 3 or 4.

Gas is on 4. The manul says to break it in set on 4. I will take it apart today and give her a look. I did cycle it by hand last night about 75 times and the trigger dropped the hammer every time. Their web site does says thet are finiky during break in.

No XCR expert here, but I would say fire control group issues would not fall under the 'break in' category and can be dangerous. I don't know the design, but if this were to develop into a hammer follow situation, you could end up with a full auto, uncontrolled mag dump and no guaranty that the bolt will be fully locked at the time of primer ignition. I would do as Art suggests and if you can't find something obviously out of place, contact the manufacturer and get their input. FCG malfunctions are nothing to take lightly.

hitman, contact Robinson Arms about the issue. I met a guy at the range who has one and he had problems with the trigger like you are having. He had to send it back to Robinson Arms and they fixed it.

This seems to be a fairly common problem of late with the XCR. there is an easy and more detailed answer to your question on the XCR forums. Basically what is happening is that there is a slight burr where the semi auto sear catches the hammer, and that is causing a failure to reset.

It's a break in issue mostly, but it can be fixed quite easily with a little bit of stoning on the engagement surfaces to remove any roughness.

the XCR really requires a break -in period. you should really hit the forums and read teh advice there as it will greatly enrich your ownership experinec and save you a lot of heartache and disgust if you have little issues like this.

hope this helped. :D

Why do they let them out of the factory like that? I'd send it back.

[hitman]

That is exactly what they told me. I called the factory the other day and they described the burr problem. They also said I could hand cycle about 100 x's and that should fix it. I did just that and can not get it to duplicate the problem. I really do like the rifle alot and think I will be very happy with it. Like I said it is pretty accurate and that was using a POS Bushnell 1.5-4 power scope I mounted on it.

[Jack-O]

That's just the gun i guess.

The gun is made modular so each piece will work in any other gun. It's only natural that the thing would require some wear-in to work 100%. It does require a 300 round break in period.

not trying to make excuses for it, it is something that the factory has identified of late (maybe a out of spec batch of trigger parts or something) and they have made the appropriate corrections, and are working with owners who have issues.

Customer service is top notch at Robinson IME, they will be happy to whatever it takes to fix your issues.

an XCR with a sticky trigger is still better than an ACR Masada you cant buy. :wink:

Maybe I'm in the minority on this one, but I just can't accept a FCG problem as a 'break-in' issue. It's a fundimental function of the rifle that is easily checked without even having to fire the weapon. Trigger operation is part of the function check I do even after cleaning.

Gritty trigger feel?... yep, I can see that as a valid break-in issue

Trigger creep?, yes again

Failure to function in a safe and reliable fashion as designed?... nope. That's a QA issue, pure and simple.

Not bashing the company or the weapon at all. It happens to the best of 'em.

I agree. FCG problems are a huge safety issue. It sounds like RA is aware of the problem and has a fix so all is well.

Good catch that Paulosantos knew indirectly of a similar occurrence.

Let us know how things turn out with the XCR. An XCR is on my wishlist now that the SCARs are selling for stupid prices.

[hitman]

Went to the range again and it functioned just fine. Did not do that again at all. I did have 1 light primer strike. Other than that it was nice. Shot at 300 yds using SSA 115 OTM and it grouped 5 rounds into exactly 3". So, I am pretty happy with it using a POS - 4 power scope.
