NEA makes Ar15...which is most of the most produced rifles in North American. The XCR is a new design and obviously there will be problems with the rifle initially.
The ACR and tavor cost the same as XCR in the States. Yet all 3 rifles cost roughly the same in Canada. It is your opinion that the XCR is a $1500 rifle. But one could also say the ACR and Tavor are both $1500 rifle as well.
And even though the most widespread problem NEA had was with a batch of bolts they outsourced from another company and have since changed suppliers people still treat them like every rifle that comes out of that shop is bad. Just like Rob Arms they are correcting issues as they become known. I give them credit for trying to do things a little different than just buying forgings from one of the three or four suppliers and just stamping their logo on it like most other brands do.
I really like the NEA lower I bought, I like how they changed how the rear takedown pin detent spring is held by the grip and not the back plate. I just had it apart yesterday to install a different back plate and it's really nice not having that spring go flying when you pull it apart.
In my opinion after owning a Tavor and an ACR and handling and shooting a few XCR-L's and -M's, the ACR and Tavor are much better built rifles than the XCR.
If you want accuracy you choose the ACR and convert it to NR with a quality barrel, If you want a compact NR platform you pick the Tavor and if you want to save a little money and risk getting one of the ones that breaks before it makes it to 2000 rounds you go with the XCR.
And before you or anyone jumps up and tries to say that converting an ACR to NR ends up with a rifle that costs $3500 which is way more money than an XCR a used restricted ACR can be bought for $2000-$2200 and a non restricted barrel can be found from $550 and up. I know of more than one non restricted ACR with a Herron Arms barrel that was bought off the EE for just under $3000. I ended up with $2500 into mine once it was converted and the paperwork was done.
I'm not trying to say the XCR isn't a good rifle but I think it's overpriced considering how many people have been on here with similar stories to the OP. It has a lot of potential but it's still not where it should have been when it was released in 2006. I like the idea of the rifle and I've wanted one since before they were available to us but luckily I decided to wait and see and I'm glad I did. I kept waiting for them to get it right, while I was waiting I tried a bunch of other non restricted options we have and settled on the ACR and am very happy with the platform. The Swiss Arms classic green, SL8-4's and the Tavor I had were close but the ACR just fits my needs and wants better than the others.
I'm going to go with the Swiss Arms for my number two choice but it would be a close competition for that spot with the SL8-4 which is also an amazing rifle but in a completely different way.
I'm glad to hear the OP is getting his parts replaced. I would have avoided Rob Arms and just gone straight to Wolverine but in the end the rifle is getting repaired so it's all good.
To me as long as someone has a non restricted semi auto and is enjoying it they bought the right rifle and it's good for our sport. I don't look down on guys with XCR's even though I'm not a big fan of the rifle and I still take every opportunity I get to run a couple mags through one just to see what improvements have been made. I'm still waiting for a chance to shoot one of the new keymod ones but I've shot all the older ones.
*DISCLAIMER*
This is just my opinion, you don't have to agree and I don't care if you like it. It's an opinion I've formed after owning most of the non restricted options we have available to us, those I haven't owned I've spent time with at the range or in the bush with buddies who have owned them. This opinion was not formed from reading every thread on every rifle talked about on CGN (but I have read most of them) but from actual hands on with the rifles.
YMMV
