Remington had re-introduced the 16 gauge Wingmaster in 4 version as recently as 2002, but there are no 16 gauge shotguns in their 2009 catalog.
not with more than one gauge in one gun, but yes they make 12,16,20,28 gauge shotguns.
sawed-off double barreled 12 gauge Remington shotgun.
Sears never made any guns. Several manufacturers including Marlin, Savage, Remington, Hi Standard, and Mossburg manufactured shotguns with the Sears name on them. Whatever company was cheapest at the time got the contract.
From 1940 to 1946 production of the Auto-5 was turned over to Remington. Serial number is on the side of receiver. "ABC" for American made Version. (A=16 gauge, B-12 gauge, C=20 gauge).
currently all they offer is a 12 ga bolt gun
One might recognize the two names Browning and Remington. They still make 16 gauge shotguns, as do a few other manufacturers.
A while back there was a long action version of the Savage Model 12 (I think it was the 112BVSS) that was chambered in 7mm Remington Magnum. The last I ever really heard of them was back in the late 1990s. I've not seen anything about it since then. For now the only manufacturer that makes a bull barrel 7mm Remington Magnum is Remington, their Sendero line, as a matter of fact.
Remington 700's are center fire rifles. Remington does make a very good 12 guage shot gun called the 870 (pump) and the 1100 (auto)- those are the popular ones i have both
