So the fact still remains that NR ACR will a lot cost more than a NR XCR. Not to mention the wait time for you to get the barrel converted to NR. The time lost that you can be using to shoot the rifle you paid over $2500 for. Those wait time could be mean more cost for the ACR depending on how you look at it.
And I am not sure how you come in to a conclusion that majority of the XCR had problems.
I personally owned 2 XCR before and never had any problems with them. So does that mean I am lucky?
And dont be so sure about the reliability of $2200 AR15. There was a report recently of a $3000 AR15 that had FTE and/or FTF issues.
I never stopped shooting my ACR, I bought a barrel and went into the verifier and had him inspect it and we filled out a single page form, I took my rifle and went shooting at the range at my next opportunity, it just remains restricted until the CFO finishes looking for an excuse to refuse it. Even if you send it in for the conversion it's only a few weeks. You act like everyone out there is only allowed to have one rifle and missing out on a couple weeks shooting is the end of the world. I would just take something else out shooting until my rifle returned.
Probably 999 out of 1000 AR's from $1000 and up to whatever you want to spend function perfectly from day one until they reach 5000-10000 rounds other than maybe replacing gas rings or an extractor spring and o-ring as long as they are maintained well and fed quality ammunition and decent magazines.
The most common problems with AR's come from guys working on their own rifle who have no idea what they are doing and end up screwing something up or putting on a short barrel and not balancing the recoil system to the new barrel's gas system length.
There are constantly XCR threads on this site with guys not even making it through break-in before they need a new bolt buffer or experience a broken op-rod or just have problems getting it to cycle reliably. Much of that could of course be blamed on the use of junk Norinco surplus which a lot of XCR owners seem to like but there just seem to be a lot more threads about problems with an XCR than any other black rifle out there. This isn't a huge problem since Wolverine is standing behind the rifle completely but that still leads to down time waiting for parts and you seem to think a couple weeks without your rifle is a terrible thing.
Yes, you are one of the lucky ones if you've never had problems. How many rounds would you estimate each of your rifles has seen?
My PWS AR has seen around 5000 rounds without a single failure or broken part. The few malfunctions it has had were the fault of the operator (me and a couple friends I've let shoot it) not properly seating the magazine. The rifle will shoot about 0.8moa with 77gr factory match grade ammo and if you open it up there is barely any visible wear.
If your idea of a lot is a couple hundred dollars (after you sell the factory ACR barrel to recoup some cost) in exchange for a rifle that, other than one report from a guy in the US who had problems out of all the googling the rifle that I've done but is otherwise a zero issue rifle then go ahead and save your $200-$300 and buy a case of Norinco surplus with the money you save and have fun with your XCR.
The XCR has been around since 2006 and they are still working out the bugs, that doesn't sound good to me. Most of the stuff they are improving should have been done years ago or from day one. This isn't the first rifle they've produced, they should know what they're doing by now. It should be 1 in 10000 rifles that has an issue not 1 in 100, the number of failures is just a guess, I have no idea how many problems they have since a lot of guys probably don't come on here to cry about their broken rifle and a lot of guys probably just get it fixed and sell it on the EE without saying a word.
