XCR What happened?

I will give you that it may be a nice option to have. It should not be required to be set "Right" to function though. I my mind, that difference is a design flaw.
Can you name another semi-auto that requires that the gas be set just right for break in, and for each type of ammo? M14 does not. Vz does not. AR does not. Sig does not. SKS doe not.

Well I have own all those guns you mentioned (Oops except an AR) but I use my XCR twice as much as all of them combined so I guess it really doesn't bother me.
When I use .223 in my XCR it runs flawlessly on any setting. It is only with surplus 7.62mm that i have to use a setting with a little bit bigger hole than the number three setting. It would run perfectly on number four but it is a little smoother on a lower setting.
Bottom line is if you don't like them don't buy one. I just happen to be fond of all guns.

Are any of the other rifles that you mention multi calibre? Is it possible that the rifle was designed this way in order to be able to handle the .223 Remington, 6.8 SPC, and 7.62X39 rounds that this gun was designed for? I don't know the answer to this question so I am asking it.

I like my xcr (x39). Sometimes i get a stuck case (FTE). I think the problem may be with the surplus ammo (steel case). Maybe the heat cases the steel case to expand and prevents ejection ?? I've got some brass case, but haven't had time to load them up and test.
I have owned all of them at one point or another as well. XCR is the only one I don't currently own. YMMV.
Me too.
No. No other rifle I know of has its barrel held on by a single screw running perpendicular to the bore.
That really wasn't my main point. They could have just given you one gas setting that would positively run any ammunition no matter what but then they wouldn't have given people who don't own one something to complain about.
I currently have 2 XCR's in 7.62x39 (long story). One functions flawlessly with surplus ammo, I have broken it in and turned the gas setting down to 3 and I have no problems with it whatsoever.
My first one however had a FTE every 40 rounds or so and every time the casing would stick in the barrel so tight that you would need to force the charging handle back and the extractor would break the casing rim and I would need to force the casing out with a cleaning rod. I called Robinson Armament and they told me that the XCR should handle Czech Surplus ammo just fine and could I please send my Barrel to them for inspection and possible repair. After they received the barrel they told me that the gas port in the barrel had been made too big during manufacture so it was allowing the casings to expand beyond what they're supposed to. They're sending me a new barrel soon, I hope, (It's been over three months now since i sent my barrel down). I expect that this will take care of the problem and my old XCR will run just like the new one.

Like I said in the 1st post... it didnt like surplus.. so he was shooting some soft point....not sure of the make... Brass cases... Anyhow.. sorry I didnt have to many details... I just thought it was odd... Spend good $$$ on a nice looking rifle... and it malfunctions like that.... I have never had a malfunction with any rifles I have owned,so I was just curious.
I must say I find this statement confusing. It seems to me that the only way the casings can "expand beyond what they're supposed to" is if the chamber is out of spec.
If the gas port is too big, use that gas regulator and turn the gas down.
Sorry to burst that bubble but there are no firearms on the market will cycle subsomic ammunition especialy 5.56 because shooting subsoninc 556 equate's to about the same performance level as 22 subsonic long rifle target ammunition which barely functions in my AR 15 w/ the ciener kit in the rifle. The only firearms that will cycle subsonic ammunition are those that use pistol cartridges like 9mm 147 and 158 gr and of course 45.acp.
The real purpose of the adjustable gas setting is to allow a operator to fire standard issue ammunition thru a suppressed rifle on automatic setting with out having the rifle beat the #### out of it self due to the increaded cylic rate that is a result of gases left in the suppressor. The Scar rifle has only 2 setting normal and suppressed .Other gas piston guns do not have adjustable setting why you ask simply because they work very well and are very reliable.
