I just checked and all the Bushmaster carbines on Gallery of Guns show as "out of stock", and that's a lot of dealers to not have any. Although that may mean they don't have any to sell through that website, but do have some in their stores. Have to check the one in town I've been meaning to check anyway. (But it burnt down some time ago, and has only recently reopened for gun sales)
I think the S&W is a better value. Academy Sports doesn’t have a great selecton of handguns, but they do carry S&W, and CZ. My son and I were looking for AR 10 (.308) clone flat tops with a stainless 20-21” heavy barrel which none offer(so we’d get the longer barrel cut and crowned)...well that ain’t gonna happen soon. I was leaning/sold Rock River Arms (16” barrel only one now, waiting for parts for the longer barrels), DPMS, (not my favorite at all) all sold out and not looking to be available for 6 mos!!! I ordered a .50 Beowulf upper from Alexander Arms a month ago and it had an 18 week turn around. I think all the vendors/mfg are waiting to see if an assault weapon ban and it’s definition will pass.
