Robarms XCR FAQ post

XCR is PERFECT for shooting outdoors, in the woods, sand pits. Shooting at metal poppers & bottles is kinda fun! :bigup:

Paid mine around 1800$ CDN shipped from a guy on this forum! Pretty smooth transaction and the gun is really nice...

Pretty nice piece of machinery! I've put around 500 rounds through it from now on and it shoots well... Gotta keep the piston tube PRETTY CLEAN, if you want the gun to be reliable...

I've put an Eotech 552 optic right on it... Making around 1MOA @ 100m.

Here's a few pictures of my AR-15 vs XCR-L. You'll notice the difference...

A little "montage"... :p

AR-15 (restricted) vs XCR-L (non-restricted)

I've installed on the AR-15 an AIMPOINT M4S optic, as the XCR-L received an Eotech 552.

Thank you for having sold me this little black beauty! :cheers:
Don't worry, i'll treat her right! :D

I'm cleaning her, everytime I come back from the shooting range...
From the barrel, piston/gas tube in the front, to the little receiver parts...

I've looked out on youtube, for complete cleaning videos (not only field strip) and they've helped me a lot... All I need is a .223 bore snake for the barrel and a 12 Ga bore snake, for the piston tube area. Finally Hoppes9 Solvant & clean patches. Lubing everything with some Militec-1 afterward...

It cleans all the dirt out and KEEP it out. :p

Which optic do you prefer?

Ooohhh man.... The 1000$ question! :rolleyes:

From what I can tell you, it's a personal preference, as both optics are top of the line's optics in "their" category... I think they are the "BEST BANG FOR THE BUCK" around...

Because I could'nt make a choice between the two, I decided to buy the two... Sometimes, you've gotta make sacrifices in your wallet! :p

I know, I know... They are nothing compared to an Elcan SpecterDR, but I can easily achieve 1MOA with Factory American Eagle ammo on my AR-15 & XCR-L...
With nice custom loads with Hornady bullets, I'm sure I could achieve better results...

For me, they are the best thing for shooting Close Range (15m to 150m).
Farther than that, you've gotta be on a bipod/rest to get good shots in the 250-300 meters range.

If you wanna do the Service Rifles matches around or IPSC, with 200-300-400-500 meters range, you'll have to use a 3x magnifier available for both optics (Eotech & Aimpoint). They are pretty expensive though (~600-700$ CDN).

Before, I had an Eotech 552 on my AR-15 and was serving me pretty good!
When the XCR got into the equation in need of an optic, I've went reading around a lot of forums about these two optics comparison.

I can't choose who's the best between my Eotech 552 & the Aimpoint M4S.

A lot of people like the 65MOA + 1 MOA dot of an Eotech (as I do too) for CQB & mid range shooting... A lot of military/police like also the Aimpoint for his AWESOME battery life. One AA battery will last around 5 years (ALWAYS ON) on a Aimpoint M4S, compared to an Eotech 552, which will have to be closed everytime, so you don't drain your 2 AA batteries (which will last around 1 year, with normal usage).

They both have their advantages & disadvantages...

Nutnfancy on youtube, already made a great comparison video, that I suggest you to see. I must agree with most of the things he said:

Bottom line: I prefer the lighter weight, longer battery life, more precise aiming dot (2 MOA on my Aimpoint M4S), more versatile mounting options, faster controls, ruggedness, and ability to seal against moisture of the Aimpoint sights.

There is a market for the CDN XCR's. The folder adaptor from RA is unexportable.

I'm sorry, I probably misunderstood you. By "folding adapter" did you mean a custom made adapter that converts the current non-folding XCR stock into a folding stock?

If you want to put a folding stock on your XCR you can just get the NEA stock adapter and get an AR folding stock. All parts are currently available and legal, so there's no need for a new custom part.
 
Thank you Terra that rifle is awesome...

Now we just need it to be released so we can get it classed as non-restricted here in Canada.

Now that I have seen the pic and if it is available in 260 Rem and in OD green to match my -L I'M DEFINITELY IN...

I know a fellow that is talking up the 338 Federal for this rifle which maybe even more to my liking...

:D
 
I don't think thee barrel is s/s from what I understand it may just be an unfinished barrel still in the white to keep costs down.
 
I haven's shot this rifle much but was out yesterday and it's fun and the SPARC works well. I replaced the stock today and it feels much nicer. I don't know if I'll need a cheek riser or not. I have a 3Bucc brass catcher on the way which will be a nice addition. The OAL with the stock folded is around 28 & 1/8" to the base of the crush washer and about 30" to the end of the flash hider.

Soooooooooo... Anyone else out there having problems with czech surplus and thier XCR?
I bought one of the newest manufacture XCR's and put about 300 rounds through it today. I was lucky if i was able to get 3 rounds without a failiure to eject, failiure to feed, or jammed case in the chamber. I know these can have a significant break in period.. an it's recommended to use "hot ammo" for the first 200-500 rounds. I haven't yet tried different ammo, and only have the one mag for now... just wondering if anyone else has had problems.

Other than that... these rifles are sweet. Surprisingly accurate with surplus.

what is your gas setting sitting at? set it to 4 during the break in, especially if you are using surplus ammo. once broken in set it to 2 for .223 and 6.8, but if you are sticking with surplus ammo leave it at 3.
 
Yup, was set at 4 the whole time...
I think it may be a mag issue.

Is the gas vent hole in the barrel significantly smaller than the selectable holes in the gas plug? The hole in my barrel looks like it's around the same size as the #2 hole in the gas plug... which would make picking a gas setting kind of pointless. Is this normal?

Have you put your piston setting to 4?

if so, you may have received one with the wrong bolt head or gas dial.

Contact rob-arm directly about it and they will give you the measurements to check it out.
