If you have a 12ga Pardner shotgun and would like to have the improved vent rib and choke you can buy the Topper Classic 28" barrel from H&R.
I called H&R on the 28th and talked with the parts dept. He informed me that the Topper Classic 28" barrel is available. One proviso, you must send your Pardner to H&R and they must refit your new barrel to your current gun.
The cost are: $85 for the barrel
$25 for the refit
$19 to ship the completed shotgun back to you
So, for $129 you can have the Topper Classic setup. Add the price of a new 28" Pardner at $128, a person could put the two together and have a shotgun that is simular to the Topper Classic. I didn't ask about the stocks being available as well. Hope this helps.
