Sorry Lucas...have not checked this in awhile.
Sorry, I am not a XCR expert as of yet,(though I did stay at a Holiday Inn) but I highly reccommend that you check out the XCR forum. You will find some straight forward questions and answers there.
I pick my XCR up in a week or so. I did get mine with the collapsable/folding stock. Besides looking cool

, I figured it gave me more options.
For what it is worth.....I was within a day of purchasing an AR. I was looking very heavy at a Panther, Sig, and a few others. Then my local FFL showed me the info and a XCR. Love at first sight!
Visit the forum...read all about it. Ask a million questions.
I plan to break my XCR in as soon as possible after I get my hands on it. If your interested let me know, and I will keep you informed.
