$499.99 Rossi LWC Single Shot Rifle 5.56 16.5" Barrel Black

[P12]

Can this setup be available in 5.56 or other calibers? It looks much nicer than the other stock.

It seems like all the different stocks will mount on the recievers but the one on the .410./45lc only comes on that model.
The stocks are listed for sale from Rossi USA and are pretty cheap.... but sold out at the moment.
