Grain of salt TOTAL newb review. I've never owned a gun and have only shot firearms a handful of times - (.22 a few times, AR15 exactly 3 rounds, 12g shotgun about a dozen shells when I was 16) I grew up doing archery and airguns so I'm not a complete beginner marksman.

Received my new thin barreled keymod XCR-L about 2 weeks ago and have 1 session of 150 rounds and today's session of 200 rounds to base this review on.

Initials impressions:
-Cool, came with a case. Wow, this case is kind of a piece of crap. Can't even fit the gun with optics. At least it came with a case?
-Wow, this thing is small...as in...toy-ish. Wasn't what I expected as far as size. For some reason, I thought it was going to be bigger.
-What's all this criticism about weight? This thing is way lighter/smaller than I had imagined.
-Keymod handguard seems awesomely tight to the barrel...am I going to need rail covers for heat?
-Sights look nice but they seem kinda cheap. (maybe that's the way all iron BUIS are?)
-This is the gas adjustment knob??? Seems kinda wobbly. As stated, I have no gun experience but couldn't Robinson Arms add a rubber bushing or something to make that gas adjustment knob a bit more solid and smooth? I guess it works and it's minimalistic so maybe that's the point?
-Quality seems awesome! How would I know? I wouldn't. Just seems like a pretty well manufactured piece of metal based on my experience with high end mountain bike parts

The downs:
-Stock works well but kinda rattles when extended. Doesn't bother me...just sayin'. (EDIT: It's a minor rattle and only noticeable if I really try to make it rattle. It's just a byproduct of metal on metal sliding parts I think.)
-Cheek piece on the stock is adjustable but not retained by anything other than slots and friction. Before I shot the rifle, I thought the piece might fall off however so far it seems totally solid and I haven't thought twice about since possession.
-Sights actually do kinda suck. They're too wobbly to instill confidence. I can't wait for an optic. (EDIT: Sights don't rattle on their own. They just wiggle around if I use my fingers. The tolerances could be way tighter IMO)
-On my first field strip, the firing pin retaining pin (which I didn't know was there) fell right out of the bolt carrier onto the floor. If I was anywhere but my kitchen it would have been gone forever. Apparently I'm missing a small o-ring to help retain that pin. Wolverine has some on the way for me.
-When trying to use a cleaning rod guide, the ejector prevents the guide from going straight into the chamber. Useless unless you remove the ejector. Maybe that's how it works with other guns as well?

The ups:
-Super simple to disassemble for a beginner like me. All makes good sense. Easy to clean.
-Super intuitive ergonomics. As a beginner I am still in that super safe self conscious mode. The XCR is very intuitive. The bolt catch/release, left side non-reciprocating charging handle, ambi safety and ambi mag release all make learning to operate this rifle very easy. If the charging handle was reciprocating does anyone think I'd have some bruises by now? I'm guessing I would.

Finally - Shooting the damn thing:
Gas setting 1, Questar Pistol mags, 350 rounds of PMC Bronze pretty much flawless, in my opinion
-1 stovepipe, no idea why. On the current gas setting, cases fly between 6 and 10 ft.
-2 failures to feed on mag change. My fault. Sitting on the ground, both times I had the rifle tilted sideways and the charging handle caught my left forearm on bolt catch release.
-Today I shot 150 rounds at a reasonable pace, then hiked out for some seclusion and shot 5x10 round pistol mags in fairly rapid succession - The gun fired totally smooth and flawless but OMFG I didn't realize how quickly the barrel heats up. Thankfully I was wearing gloves because I grabbed the barrel while preparing the rifle for transport in my pack and I heard a sizzle as the snow from my hands boiled off. Beginner error.
-Despite the red hot barrel, the handguard was air temp...tested with a bare hand (+5c and sunny today) I can't see a need for rail covers yet.
-About 1 in 10 rounds has a dented casing on the shoulder
-Sighting in required the rear sight to be 2/3 of the way to the right. I have no idea if that is within the expected range or not. Could be the shooter?

That's it. Having so much fun shooting this gun. I love it. Apologies if I sound like I don't know what I'm talking about...I don't. Lots to learn.

Well done, congrats on the new rifle.
Hope to see an accuracy test once you get your optic mounted. Hopefully you test it with a few different types of ammo to see which it does best with.
 
Your FAST stock rattles? Maybe check all the fasteners. The sights should not be wobbly. While they are not the best sights, mine were pretty dead on when I first shot the rifle.

Just a word of caution and something I do to cover my arse (mainly because I am paranoid about the FA ignorance of LEOs). Carry the RCMP regulations for the 10rd pistol mags when shooting in the bush.

The stock barely rattles if I shake the gun. No fasteners are loose. I think it's just the way it is when you have mated metal on metal sliding parts. No biggie. The sights don't wobble around...they can just be moved around when grasping them with my fingers. Definitely not bomber construction. I think the production tolerances could be way better. As for the RCMP magazine regs, I got copies of those things ready for polite presentation coming out my yingyang (car, rifle case, wallet, backpack). It's a good tip. Thanks for looking out for me.

Thanks. I am planning on shooting another 300 rounds of PMC and then I am going to try Norinco surplus. If I don't have an optic by then, hopefully I can at least add some reliability/gas setting data.

Don't expect great accuracy from the Norc, it is just fun to plink ammo.

Interesting I did not know this...Q'n 1: Where can I get a copy of these guidelines as when I go to the RCMP site the link always comes up error. Q'n 2: Who makes the 10 round mag to meet these criteria for the XCR-L?

Don't want to hijack....so check these links and search the forum.

The stovepipe could be explained by the requirement of a break in period. By this review would I be correct in assuming you're the first owner and this is the first time it's been ran?

I don't know if the new keymod XCR require the same break in, but older XCR require starting on the highest gas setting that the rifle will reliably operate on and working back to the lowest. It'll be in the instruction manual.

However with only 1 stovepipe on a new XCR with setting 1 it sounds like you can get away with breaking in at setting 2. That's quite the improvement in the gas system if all new keymod are like this, definitely a thumbs up.

Glad you're enjoying the new rifle, more owners the merrier :D.
 
Thanks loki_81,

This is a brand spanking new rifle. Aren't there are two opposing schools of thought on break in? I believe Robinson Arms themselves has swayed towards the newer school of thought of starting with the lowest gas setting and work your way up if there are issues. Once past a reasonable number of successful rounds, move the setting back down until you reach...nirvana. Apparently the owners manuals need to be edited (says Wolverine). I'm not concerned about the 1 stovepipe at all. I just mentioned it as an info point and for transparency. The rifle seems to run just fine at gas setting 1 with the current ammo.

I love the gun. It really came alive when firing those rounds in rapid succession. It was as if the gun was speaking to me "This is what I was built for."

Definitely break in at the lowest reliable setting and go down from there. If it's operating acceptably at setting 1 or 2 then you're in the sweet spot.

Some ammo is 'hotter' than others, so keep in mind that if you get feed issues with a certain brand, or in different weather conditions, then you may need to go up a setting or two until the issue is resolved (and it's broken in for the different brand).
 
Some explanation?
Recently have problems at the range with not fully retracted Firing Pin
after the Bolt in the far back position. Disassembling the bolt sowed me that
the actual Firing Pin had been broken/damaged Due to poor quality of metal
or types and/or methods of Hardening?

Personally I have heard that broken firing ping are pretty common these
days for the earlier types of RobArms Line of products..

This must have something to do with the price of eggs in China?

Are you at the Egg forum?

Or... I think he was politely trying to poo-poo all the negative comments regarding his situation with the XCR.
