XCR pre keymod lightening

How about barrel fluting? I that a possibility or would this introduce a potential safety issue?

Even better - have the barrel "turned" to something close to pencil profile.

With the current pricing on new XCR stuff, it seems to me that $75 an hour goes a long way.
 
I'm going to see a gunsmith next week and ask him about either fluting the barrel or turning it. I read that there may be issue with the barrel curving as it's being turned depending how the barrel was made (if it were stress relieved or not).

Used prices increase just the same when the cost of new goes up.

Barrel turning or fluting may have adverse effects on accuracy and certainly reduce resale value. I still recommend selling and buying the newer lighter model to save the most money
 
I have an XCR with modifications similar to what you are looking at having done. Unfortunately, I didn't have the work done myself, so can't offer much in the way of guidance other than some photos which will give you a better idea of the finished product. I purchased this rifle on the EE about a year ago for $1500 CAD. It is a restricted , 16" U.S. version, imported by the previous owner from California. I know this only because I had to remove a "bullet button" which is unique to that state. But I digress...

As you can see, the new holes in the receiver mimic the existing vent holes, versus MLOK-sized ovals. The mods to this rifle predate the rise of MLOK. Note that the previous owner left the entire bottom rail. I'm not fussed either way, although in the interests of further weight savings I wouldn't complain if it were reduced to just a small rail at the front to match the sides.

I'm glad that the previous owner went with the LWRCI-like spiral fluting on the forward part of the barrel as I really like the look. The rear portion of the barrel under the receiver is longitudinally-fluted. The parts were refinished with what appears to be CeraKote following the machining. The entire upper receiver was redone to match the anodizing on the lower and the barrel was done to mimic charcoal Parkerizing. A subtle, but distinct difference between the two colors, which is very convincing.

And without further adieu.....

I understand it may effect the resale value, however, the xcr will probably be the last gun I would sell. So I'm not too concerned with that.

Dude, that's awesome!

How is the accuracy of the rifle?

I'm trying to figure out whether or not the XCR barrel is button rifled or cut rifled. It seems that if the barrel is button rifled, then the accuracy may be effected by fluting due to the stresses caused by the button as it displaces material in the barrel. In a cut rifled barrel, the material is cut away thus the stresses are not present which should not cause the barrel to be less accurate.
 
The accuracy seems fine - on par with the other, earlier XCR that I owned. I am getting around 2 MOA with decent ammo, more like 3"-4" groups at 100 yds with "Norinco plinko" ammo. I have no idea how RA (or their sub-contractor) rifles the barrels, but the after-market fluting done to my rifle doesn't appear to have altered the accuracy one way or the other. As always, YMMV!

Best of luck with your project. The mods done to my rifle (and the low price) were the reason I bought another XCR.

Nice rifle, any idea what the cost to get all that work done today in canada would be? what is the current weight of your bare rifle?

I think you will find that the cost of the work above will far surpass the cost of selling your current rifle and buying the newer generation xcr that is already much lighter.

Nobody ever intends to sell, but it is reality as our wants change.

Sorry, I have no idea what it would cost to have all of that machining done, plus the CeraKote afterwards. It certainly wouldn't be cheap to do on top of $2400 CAD for the basic rifle......

No scale in the house, so I can't give you a weight. That said, I think that the real value is not so much in the weight loss as it is in the reduction of weight forward, lending the rifle a much better balance. It is quite "lively" in the hands now, as compared to a stock XCR or even my 16"(restricted) ACR. The more rearward center of gravity on the modified rifle has to be experienced first-hand. It really does change the entire feel of the gun.

Cheers,

Reviving the necrothread:)

Anyone actually go and get MLOK slots installed? Did the inside diameter work as well? Any regrets?

Thanks!

the problem with keymod/mlok is that you have to remove all your keymod to remove the barrel... for most people its a "meh" because they don't swap the barrel out but man if your switching between the range barrel and the hunting one what a pain in the butt.


As for machining it down... I paid $100... then $300 for the hydrodip

Yup, I think we pm'd back and forth.

I plan on using the milling guy you recommended. (if that was you). As I only have one barrel, it should be ok. I like what you did, matching the milled sides to the factory vent holes. Clean and not even noticeable that there was work done.

Just wondering though: If I do the keymod holes, will it actually have enough room behind the mounting screws to work? I assume it would, based on the newer monolithic uppers in Gen 2. But, it would be a shame to mill out keymods that were for aesthetics only!
