Here's mine, my dad won it in a raffle. Couldn't handle a single in 12ga at that time so he gave it to me. I cut it to 18 1/2 and replaced the bead. Used it for rabbit hunting for years. Decided to put a poly choke on it to make it more versatile. Oh and those barrel clamps that come on new Mossberg combos make great light clamps. Easy on easy off. Shoots a little high being that short. And your over $100 on the poly choke. The screw in option would prob be half that.
Oh really! I would agree with that thought (possibly)
if a fellow was sending his barrel/gun to the @Polychoke company for a [brand new] installation,
But what I've been aiming for is finding a "used" polychoke" attached to a couple inches of barrel stock after the seller (or someone) cut it off a previously used barrel!
Then the next step is getting the 'smith that agrees to re-install it,
to clean it up first (by unsoldering or detaching it from the old stock-barrel .....) then assembling my barrel.
On fleaBay such used polychokes are listed weekly (and daily at times), usually selling for $15-$25 range. Sometimes less (or more).
One seller had eight polychokes he listed in two listings (of 4 each).
I stoopidly missed 'em both! If I had won one of them, probably could have sold what I didn't need to almost pay for the one I would.
BTW, have seen polychokes installed on a couple [cheap] singleshotties (old Winchesters, Savage/Stevens, H&R's, etc.).
None were pretty, but functional? HECK YEAH! 
BTW PerryTrails, that's a great looking rig in those pics! Thanks for posting them.
