Welcome, glad you like it thus far. I am sure it will not disappoint at the range.
XCR arrived yesterday
Well my XCR heavy barrel arrived in my hands yesterday. I must say the fit and finish is quite good, I am impressed! The guys and gals at Robinson put together a really good looking rifle. I've fired the SCAR and handled the Masada and I have to say at first glance the XCR is easily a match in quality. Now to see if it functions as good as it looks. I'm sure it will. I will be taking it to the range with 1200 rds of mixed ammo and giving it a good workout this Tues.
I'll post my range review and pictures Wed.

1200rds in the very first session, wow, that is brave. I will be interested to hear that report indeed. 
I'd make sure I torqued down the ejector and took plenty of lube with me.

I have already torqued the ejector bolts and JB welded them in. I have found over the years JB weld works far better than loctie. OK before that starts a conversation of its own, yes I can still remove the bolts if needed. I have extensive experience with JB weld.

I once has a girlfriend that tried to jb weld my zipper shut....... :ninja:
Not to make it turn into a conversation of its own, but, I do have some JB weld as well... you think that would hold my ejector in place better than locktite?
if you ever were to have a problem with your ejector, you may want to be able to remove it.
Yes JB weld will hold better than loctite but you have to use it correctly or you will not be able to readily remove the ejector bolts. (if needed?)
I used red loctite on the bolt threads and then a small amount of JB weld on the side of the bolt to act as a spot weld. The JB weld can be removed easily with a pair of needle nose pliers. This is the same set up I have used in off road racing for years on bolts in high vibration, heat and oil conditions.
PM me and I can send pictures.
While we're on the topic of bolts does anyone know why these two bolts are not Allen heads like the rest of the bolts used in the gun? It would seem to make field repair (if needed?) much simpler to have one type of tool system instead of two.

Took the XCR HB to the range with a few of my LEO SRT buddies and we shot the snot out of it. 1200 mixed rds(USA, FEDERAL, NORINCO, WOLF, LAKE CITY) of which 900 were shot on setting 2 in about 2 hours.
We had one FTE and five LPS. The LPS were with Wolf? The rear stock bolt came loose and the ejector bolts started to. This even after using red Loctite and JB weld to hold them in. But in all fairness the ejector bolts held for 1200rds.
We all found the XCR to be a excellent rifle. Well balanced easy to use with low recoil and min muzzle climb. Accuracy was as expected for a combat rifle after all it was not built to be a sniper weapon.
The only real concerns voiced by all was about the LPS's and ejector bolts. None of us have ever had any LPS with Wolf ammo on any other rifle. Could these have come from the low gas setting? :-\ The ejector bolt were the second concern. Even though the held for the whole 1200 rds we could see this becoming a continues maintenance item which would take the rifle out of service for longer than a day for repair(drying time for red loctite). Not really a problem for LE as we have maintenance schedules for this kind of thing, but we could see it as a problem for those in the field.
All in all, we really liked the XCR and I think Robinson will be selling a few more shortly.

Light Primer Strike, I believe?
dam, a hardcore test and the XCR fails. 1200 is not that many rounds, but I can see why the red loctite would fail on the ejector bolt as you shot 1200 rounds in a hurry and there was not enough time for the weapon to cool. sucks that we even have to use red loctite, and sucks even worse that even after using red loctite the rifle won't go more than 1200 rounds before coming lose.
XCR will never be elevated to battle rifle status like the FAL until it can go 2000 rounds without a cleaning. :'(

If "LPS" = light primer strike, I would check to verify that they hammer spring is installed correctly from the factory... I believe it should be positioned in the same manner as that in an AR lower. If it were wrong, I bet you would have had more than 5 though. Maybe some gunk in the firing pin channel?
Still sounds pretty good for 1200 rd first session on a non-broken-in rifle. How much did you lube during the process?
I imagine these ejector bolts are going to have to be entirely redesigned someday. They seem to be by far the single biggest weak point of the entire platform. At least it sounds like it will be possible to retrofit existing rifles by replacing the upper if desired.

Yes, LPS=light primer strike
The gun was lubed only once prior to shooting. We used a new aerospace synthetic oil which has a high burn off temp something like 600+ deg. Great stuff! Although the gun never really got that hot after all it's NOT a DI system.
I would in no way say the XCR failed. It is a excellent rifle and the LPS could have been caused by a number of thing. The LPS only happened with Wolf ammo which IMP is good for practice but I would not bet my life on it. Also the gun was pretty fouled with carbon & debris(primer sealant, brass, copper and metal particles) and that could have caused the bolt not to lock as tight as needed. We took pictures of the fouling, but the picture size is to large to post.(PM me if you would like to see them)
I would agree that for this rifle to be IMP the world better it is capable of becoming the ejector bolt issue must be solved.

I would like to see the pics... if you can send them to me, I can resize and post them. [email protected]
Check out my review. Well over 2K, no cleaning necessary. This was with Winchester white-box 55gr FMJ.XCR will never be elevated to battle rifle status like the FAL until it can go 2000 rounds without a cleaning. :'(
Even so, the XCR-L can't be "elevated to battle rifle status", as it's a carbine. If you want it to become a battle rifle, you're going to have to wait for the XCR-M, like I am.
I have never put more than 1K through mine in one sitting and they weren't rapid fire as fast as I could go but with over 5K rounds I had never even looked at my ejector bolts until I found this website. I got mine June 2006 and I remember when I picked it up Alex told me that I may want to check a few bolts but in my excitement I forgot which ones he said. After I found this forum last month I checked all my bolts and not a single one was loose. Not even the gas block.
If someone is that concerned about the ejector bolts they should red locktite them then add slippage marks to the heads and check periodically.

We use wolf exclusively for practice ammo here and I have noticed a few LPS's during the last two years. We never had any problems before with the lacquer coated stuff, but the polymer has shown some hard primers. I would say we average 3-5 per 1000.
I would like to see allen head bolts for the ejector as well, although I keep a wrench in my range box. No loctite on mine, but I periodically re torqued them early on and check them every six months or so.
It does seem to be the only potential hiccup in a wonderfull gun.
