I cant say for that particular model; but EAA (European American Armory), was offering 30-30 and 45-70 inserts for the Baikal coach guns with 20 inch barrels. There were several different models that could use the inserts, and Im pretty sure some had hammers. All of the acceptable models had screw in chokes.

The inserts were "loaded" like shells into the breach of the shotgun barrels, then one of two "spacers" was placed between the barrels and the muzzle, and finally a nut was screwed over each of the inserts against an "O"ring onto the shotgun muzzles. The spacers allowed some regulation. The barrel nuts are knurled and extend about 3/4 on an inch beyond the shotgun muzzles. A "L" shaped rear sight was included that had to drilled and tapped onto the rib.

I believe they were made by Franchi or Tangfolio. Originally they retailed for about $150.oo each. Last I saw the 30-30's were well under $100.oo at CDNN.

There was no requirment to bush the firing pins. The assembled gun was fairly front heavy, and the barrel nut made a CAPE Gun unimpressive, as the nut would extend on one side. In fairness it was a good idea that could have been done a little better.

At 300-400 for the gun and another 300 for two inserts, it was priced right for beginners, but certainly not a real double rifle. My biggest complaint was picking the coach gun for the platform. Perhaps it was because of overall weight of the assembled gun; but I would have much rather seen a 24 or 26 inch barreled version.
