NR Rifle Battle ACR vs XCR

I did say AK mag lower



It may be crap but so is 223/5.56 when it really comes down to it. I wonder which cartridge and rifles chambered for it is more prominent in todays world, Has the 556 overtaken the x39 AK?

You want them to go through the trouble of making an AK lower as well and you want the complete rifle for what $2000-$2500 so it's competitive with a used XCR or ACR?

Ballistically the 5.56 is far superior to the x39, it may not make as big of a hole but the increased velocity gives it energy not that far below a x39 round. I don't think anyone wants to get shot with either round.
No, it hasn't overtaken it in world conflicts but it must be getting close, and the x39 has been around since what? 1944? That's about 20 years more than 5.56.
If you want to shoot x39 run it through a rifle designed around the cartridge not a rifle converted from 5.56. Reliability is lost and since there are a lot of ranges out there now that won't allow steel core is x39 really that great? I've even heard there is a province out east that doesn't allow it on crown land. Plus, shooting corrosive out of my $3000 rifle doesn't exactly sound like a great idea. I don't like having to clean my rifles in a bathtub, a quick wipe and bore swab is all I want to do when I get home.
 
The neat part about x39 is that 50 Beowulf uses the same bolt face so you are only a barrel change away from the ultimate big bore.

300 blackout is not my thing, 30 AR (RAR) seems more promising if you want to use it for a decent hunting application. When compared to 300BLK the .30 RAR has 83 percent more case capacity, which means it drives similar bullets faster and with more energy. It has over 26 percent more velocity with a 125-grain bullet, which means a 60 percent increase in energy. That means the .30 Remington AR is by far the best factory option in a .30 caliber for hunting big game with an AR-15 rifle. It is just a shortened and necked down 450 bushmaster or 284 win case

non corrosive x39 ammo is still considerably cheaper than 223/556

Maybe 30AR or 50 Beowulf will be my next ACR project after I get the 6.8SPC barrel working. I currently have that barrel in an AR upper doing some load development.
I did some work on the extractor the other day, now I need to get it into the rifle for some testing. Hopefully I have that working soon so I can start another conversion.
 
I like this XCR over the ACR

i dont think so that the 5.56 is superior maybe for a longer range and that all , it will go thrown less stuff than the 7.62x39mm , if we were able to get some cheap surplus in 5.45x39mm this one is better than the 5.56 , people that dont clean their riffle after the range or bush are just lazy in my opinion , i shoot corrosive out of my xcr-l and dont have any trouble with that , in the long terms with my .19 $ a round i will have shoot 2640 round when you only have shot around 1000 , there make a big difference , i prefer to be able to shoot more than twice and have to clean. never had to thrown the rifle in a bathtub ,
 
I find the xcr keymod feels much better than the acr, the acr feels like a heavy, cheap plastic, toy gun. And I owned both, as soon as I picked up the acr I hated it, if I had to own a .223 rifle it would be either an xcr keymod or an sl8

I tried to give the xcr a chance many many times, just didn't feel right when I shouldered it. I felt the same way about the XCR as you felt about the ACR. Reliability and accuracy were important for me on this rig, so I bought an ACR instead.
 
Not sure how any modern rifle (which is essentially totally the same) "doesn't feel right" when you shoulder it, but okay. The only difference you should feel when you shoulder an XCR vs ACR is the better balance of the XCR. From there on you'd really have to shoot both to figure out what suits you best. Robinson picked up a bit of a bad reputation early on, but considering you don't deal with them up here (you deal with Wolverine) it shouldn't matter much. Personally I don't think their later guns suffer from any more reliability problems than other similar platforms. They've been producing and revising them long enough that they've got a pretty good product going by now.
 
With a nonrestricted rifle, the idea behind it is hunting coyotes, gophers, etc.
That puts accuracy at the top of the list in my opinion. Acr wins.

If you are hunting somewhere that you're at shorter ranges where a 2-3 moa rifle is acceptable, the tavor is a better option than the xcr due to its more compact size and better ergonomics for shooting unsupported.

They all suck compared to a noveske or kac ar15, unfortunately.

Really? Because my idea of it is simply not being in a government police database....

But whatever.
 
I've owned both an XCR Keymod Light Barrel and one of the first Questar NR ACR's with a White Oak 1/8 twist Wylde chamber. I've also owned a variety of high end AR's for comparison (KAC, Noveske, JP Ent, etc).

For the price, it is hard to beat the new XCR Keymod Light barrels. They seem to shoot factory 55 grain ball, fairly well, however I did not find that the accuracy improved much with match grade ammunition. In terms of accuracy, 1.5 to 2 MOA was fairly easy to achieve from a bench, with a magnified optic. The rifle balances well, and feels great. It is pretty modular, grip, stock , rail, etc, and I never had any reliability issues, at all. The light barrel heats up quickly, and accuracy starts to fall apart, especially at range, when the barrel gets hot. I did like the fast stock, however I had to modify it slightly, to get it as tight as I'd like it (adjusted the screws and added a rubber bumper in the folding stock end to provide counter pressure). The new trigger feels great, although not nearly as nice as the ACR Giessele Trigger.

The ACR feels cheaper, in that it has more plastic parts, and in its' NR configuration is front heavy. The plastic, non modular lower is a big factor in the cheap feeling. If we ever see the metal lowers, that will be a huge improvement to the ACR. My ACR was very accurate, and the barrel responded well to better quality ammunition (0.75 MOA to 1.5 MOA). I never had any reliability issues, although I never really liked the recoil impulse, compared to an AR. The Giessele trigger is amazing and adds to the accuracy of the rifle.

If you want a quick handling, fast shooting, NR combat rifle with a red dot or 1-4 optic, I'd go with the XCR keymod light barrel. If you want to build a DMR style rifle, for target, varmint, or other similar purpose, with a higher power scope, then get an ACR with a quality barrel (Medium profile, SS, 1/8 twist, Wylde Chamber). Neither will be very competitive for competition shooting, and neither can touch the capabilities of a purpose built AR.

Many people are not so lucky and if we ever get our mag limit restriction removed try it with a standard capacity magazine. There is a reason the AK has a curved magazine and it's not just so we can call it a banana mag.

Im gonna stop driving my crappy car, because when my Male Modeling contract comes through Im getting a new Bentley.

ASC 10 round pistol mags work. Period.

if the ACR gives you a cheap plastic toy feeling, you are not going to like an SL8

I wish they would have done all their product testing in house rather than selling their product and using customers as beta testers. My experience with an earlier model has soured me to buying their product unless I can get a hold of one and do some extensive testing prior to purchase.
 
I'd buy an xcr tomorrow if they'd pull their heads out and accept the fact that a pinch bolt is not an acceptable barrel attachment method, and quite detrimental to accuracy. That really is the only problem with the xcr, but it is a significant one.

Any different to other manufacturers? ACRs were shipping with problems, they even had a recall if I understand correctly. FN shipped SCARs with visibly crooked barrels, its all out there just gotta look it up. Ultimately, those with bad experiences will be most vocal. I think if Wolverine was having a hard time with XCR customers they would've stopped carrying the platform long ago. Just my 2 cents.

the XCR is how many design revisions in and all of them had problems ( I believe even the newest keymod has a post or two here). hard to compare that to other rifles which are still on version 1

Of course the people who had problems are vocal about it, they have a right to be.

I have also posted many times about the rifles that have been 100% reliable for me but people don't like to hear that part I guess

but for one unhappy customer you probably have 99 happy customer , in every brand of guns you will always find a lemon or somebody that dont like something about something
