They were in stock at Cabela's Winnipeg a year or two back; dirt cheap too, I think under $300 on sale. I picked one up and use it in the backyard on House Sparrows and Starlings around the bird feeders and bluebird nestboxes. Mine's a 12-gauge; with the supplied turkey choke and #8 or #9 shot it produces stupidly dense, tight patterns at 20 - 30 yards. Works great without tearing huge holes in the foliage, easy to shoot close to feeders or branches without hitting them. I don't turkey hunt since moving to Manitoba, but did a lot of it in Ontario and this gun would be very effective with 4, 5 or 6 shot at longer distances.
The optics rail is screwed to a metal bar welded to the top of the barrel; take off the rail and you still have that big-ass bar in your field of vision, but as long as you use the rail and a red-dot you're golden. I wish the rail were a bit longer, but it works. If you're accustomed to the old H&R singles, the idiotic safety they have added to this gun can catch you off-guard once or twice until you get used to checking it, much like the cross-bolt safety on current Marlins.
I much prefer shorter barrels with actual iron sights for turkeys; I would usually be hunkered down into brush or tall grass and a big long barrel is tough to swing around without moving the greenery and attracting attention. The all-time greatest turkey gun I ever had was a 10-gauge H&R single-shot, a very heavy-barreled "goose gun" with I believe a 32-inch tube and fixed full choke. I had the barrel cut down to 20 or 22 inches and threaded for an ultra-tight turkey choke...Colonial, I think it was. It eventually had iron sights on it, as well as a short piece of pic rail screwed to the barrel in the forward "scout" position for either a scope or red dot. Absolutely loved that gun. Super compact and murder on turkeys.
