Many new members have asked specifics about sending a frame in for accessory barrels, you can send it by mail or other carrier like UPS or Fedex, but H&R will return it by UPS after fitting the new barrel(s). A lot of members including myself just send the frame and order a stock set, or just order a forend that will be dedicated to the new barrel if you intend on swapping barrels around on one frame. Many don't like to send a nice stock set at all cuz sometimes they damage it while fitting/handling, sending just a frame in a USPS priority small flat rate box will cost ~5.00 plus insurance and they'll have it in 2 days, 3 at most. You can also break the butt and frame down and send them with the forend, if you don't order one separately, in the larger medium flat rate priority box for ~$11 plus insurance. Some members don't send any wood at all, just the frame even tho the instructions say to send the butt and forend.
