XCR-L, can it be built better?

So the XCR-L platform, when swapping out barrels for something a little better accuracy wise (quality SS) could a modification be made to retain the barrel in a superior way to the factory single screw option (more then one screw or a better design for better retainment consistency)? I'm researching possible options to an AR for semi-auto accuracy in an NR platform. Thanks in advance Nutters...

Get an ACR and have a custom barrel made from a stainless steel match blank. The barrel retention system in the ACR is light years ahead of the one in the XCR, and even with the stock ACR barrel, I'm getting close to MOA with my handloads I developed for the Swiss Arms.

You know no one has ever mentioned it but yes there is a very very simple way.
If you don't plan on removing your barrel all the time, and there really isn't any need to.
If accuracy and caliber changes are important you can have complete dedicated uppers.

Locktite or epoxy the barrel in place.
The barrel retention will be rock solid.

And neither of those are really permanent. Both bonds can be released with chemicals and or heat. A bit of effort is required but once again, it will be absolutely rock solid, yet it can be reversed without damage to either components.

That won't help accuracy...
 
Well everyone claims the barrels retention design is the reason it lacks in accuracy.

Personally mine shot pretty well, about 1.5- 2moa with American eagle/pmc.

Take the barrel retention out of the equation and what else is left that'll make it inheritantly less accurate than the ar/acr

Is it even possible to get a new barrel extension so you can build and install a higher quality barrel?
As far as I know you would need to machine a completely new upper receiver.
Why not just accept that it is never going to be a consistent 1.5-2 moa rifle and get the factory light barrel for better balance and simply enjoy it for what it is.
If you want something else buy a different rifle. You won't lose much money selling an XCR and you can put the money towards a different platform.
The XCR was designed to be reliable and easy to maintain battle rifle. DMR was not part of the design considerations. If you can hit a 12 inch plate at 300yds it's doing what it's supposed to do.

If you want accuracy buy an SL8-4 or an ACR. The ACR will need to be converted to non restricted but that's easy.

I would be buying the XCR-L in 7.62x39 and I don't believe that calibre is available in either the ACR or the SL8-4 unfortunately, otherwise the HK would be in the safe already. I respect your opinion CR5 and always read with interest when you post, it's just unfortunate I/we cannot use an AR platform as a NR rifle.
Add to that no one has to my knowledge created anything that compares to an AR with respect to accuracy and reliability in a NR semi-auto. rifle with the 7.62x39 calibre. Others may disagree, but I do not wish to hunt medium sized game with a .223 rifle or for that matter approve of the .223 cartridge for real world conditions where wind and foliage may become issues at greater distances beyond 100 metres (if I were to enjoy the rifle in NR status). I may step up to the 7.62x51 Rd. with a FNAR, but do not prefer the dis-assembly required to care for that rifle and would prefer a smaller lighter rifle ideally (not to mention the increase in ammo. cost's over the 7.62x39 Rd.) and I'm aware of the RFB and others.

Thanks for your input CR5...

XCR-M is the one you want then. Or an RFB if you like bullpups.
You could always go the same route I did and just build an ACR conversion in 300 Blackout. I have about an hour worth of work left to finish mine, I just need to get a chunk of stainless from my buddy at the machine shop to build a new op rod guide and it's finished. I've farmer brown'd it for now and taken a couple test shots but I want to finish it right before I start load development (pics in the ACR info and media thread).
My barrel builder has a couple more McGowen 1:8 twist blanks and can build more barrels if you're interested.
300 Blackout walks all over x39 if you are a handloader. So much more versatile and brass is free if you shoot 223 or don't mind picking it up at the range.
 
The xcr needs first a quality barrel blank.
Then the barrel/extension need to be built up to fit the reciever without slop. This can be accomplished a few ways, I won't give away any secrets.
Then the upper/lower fit needs to be tightened by drilling and tapping for tensioning screws.
Apparently they're decently accurate after that.

My tikka will out shoot both the ACR and XCR
