If I may ask, how much did they charge and what was the turn around time?I recently sent my XCR Mod 0 back for an update. It now has all the Type 2 trigger and bolt group. along with the Type 3 gas system. I also updated the stock. It turned out awesome with a very reasonable turn around time and cost. I would highly recommend you sent an older XCR back to them for the factory upgrade. Here is the result.
But at that price point, unless you paid under $1K for the original rifle, it doesn't really make sense.For all they did it was under $800, about 60 days turn around time. There is a whole list of upgrades you can do, just email and they will send you the information. I highly recommend it.
