You can just start with a x39 xcr and get him to swap the barrel no?

Only if you want to totally change the caliber/parent case.
If you wanted to change an AR from 223 to 7.62x39 you would incurr added expense as well. Bolt, brake and barrel minimally. AND it would STILL be a restricted firearm, there are some things we just can not change.
Understand we are NOT trying to reinvent the XCR simply offer a higher quality barrel in a few additional calibers. The barrels we produce are far higher quality than are used on "production" rifles, we have proven this on he AR platforms.
Will replacing the barrel improve the reliability of the rifle? No! But it will NOT make it any less reliable, just probably more accurate and if wanted a different caliber than what is offered currently.
Yes for someone who hasn't bought an XCR yet they could just buy the 7.62x39 XCR if they wanted to have it barreled in 6.5 grendel. But for myself I would have to buy the 7.62x39 kit for my XCR plus pay for the barrel work.
That is where I believe you are wrong with the 6.5 grendel using the 7.62x39 bolt it will be less reliable that I can almost positively guarantee.
Rebarreling a .223/5.56 to the same caliber or something like 6x45 shouldn't be a problem though and should infact get the accuracy improvement people are looking for.

Rereading this post I think I may have misunderstood it.
What I thought you meant was that we would cure the inherrant lack of reliability issues surrounding this rifle.
Rereading it , it seems your concern is the differences in the bolt that may not allow for the 7.62 bolt funtioning with the 6.5 Grendel??
This is something that we will need to look into further, because if there is this problem, obviously we do not want to supply a barrel if the failure to funtion ratio gets worse.
In retro spect we may have jumped the gun, so to speak in posting this prior to getting some barrels made and tested

No problem. I think if the 7.62 bolt worked Robarm would have released a 6.5 kit already which they haven't and have had problems getting the 6.5 to function reliably in the XCR thus far.
Though I am considering a 5.56 barrel in a lighter contour and perhaps a 6x45 barrel for hunting. Light on funds right now cause I just spent a bunch on landscaping my yard and gave my brother a 5k loan for his new house. But in a month or two I will definitely consider it.
Another question would you consider doing a 6x45 barrel for the Tavor? Now that I would definitely be interested in.
I will be a guinea pig if you wish.

I have seen 1 Tavor, never shot 1, never had 1 apart, so the best answer I have is "I don't know"
I would need to know alot more about the Tavor before making any decision as to whether it was feasablefor us or not.
No you aren't and for your question I do believe it said in the first post that 223 wwyde chamber is available so you are good to go.

ATR, that rocks. Any posts of pre and post op groups? Can the XCR ever become a 1 MOA rifle? Or is that just a pipe dream?
I've had my XCR for over 2 years now and shot approximately 1500 rounds but never had anything better than 1.5-2.5 MOA on a sandbag (using cheap 55gr UMC). That would be amazing if the accuracy could be improved. Anything else that can be done?

The issue is the bolt face size. The case head of the 7.62x39 and 6.5 Grendel should be the same as they are derived from the same parent case. Thus a 7.62x39 bolt should work for the Grendel case
Headspace is a completely different and largely irrelevant issue here because we are talking about a custom chamber specifically cut to fit the bolt and extension on hand. How can you have headspace problems when the chamber is specifically cut to fit the round using the supplied bolt?
The only potential issue with the Grendel feeding is the shape of the shoulder and body. The case was designed to feed through and AR so I am fairly certain it will work with the XCR but we are admittedly treading new ground here so I suppose that remains to be seen.
Yeah sure, we will just give away all our secrets so that anyone can duplicate our product and make the work we put into this project totally worthless. Do you want to come over and f**k my wife while we are at it?
Yes you are and we thank you for it! I was hoping you'd go for something like the 20 Practical so we'd have an excuse to buy some .20 cal barrels.
Well, seeing as we only got this thing apart today .......... NO.
Up until this point we weren't even sure the barrel extension would come off intact. Apparently Robinson Arms has claimed on other forums that it is impossible to get the extension off without destroying it. So just getting it apart was a big step.
However now that we know how to get the extension off, the way is open to make replacement barrels.

Im pretty sure actually 100% sure its not your secret and its not your product, your talking about a XCR product not yours. FYI you are copying XCR.
Simple question deserves a simple answer, way too funny!!!
