Yes, and it's a great idea now since you're buying a stock anyway so no extra cost. PSA sells the milspec tube for $20 last time I checked. It's good to go, I paid a little more and got their full kit that also came with buffer/spring/end plate/castle nut.
My buddy did this to his BM and they assembled it with gunk on the threads so it was a female dog to remove.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together. You'll remember the quality of a gun long after you forget how much you paid for it.
