If you are using it for hunting make sure before you chop it down you have the velocity you need to expand your bullet of choice at the ranges you want. Can’t put it back on.Mine is also is 6.5 creed. A friend gave me a 308 20" AT barrel that I know shoots tight. I may send it out to get it cut flush to the chassis for hunting.
I don't see anything on the AT-XC worth doubling the cost. That being said, some AT-X parts are perpetually out of stock. Parts that the AT-XC already has. That alone may be enough to convince the consumers.
Mike high has quite a bit of the accessories now in stock the hinges are becoming more available. $2000 price hike for accessories is quite a premium.
That is one thing I have always abided by. Buy everything for the gun you have at the time you buy it. The hinge was the only thing I had to wait a month to get. Everything else mile high had.
