I owned one in 12 gauge that was bought in 1960 by my cousin. The shotgun was Remington's first successful gas operated semi-auto. Mine operated reliably once I replaced the broken flat spring in the magazine tube (half the tube is for shells and their spring, the other half is for the gas piston and it's spring). Broken flat coil springs are the culprit in causing bad operation in this shotgun - get the coil spring made of music wire (I believe it was a Wolfe). I liked the roll engraving too, but I also liked the post-66 Winchester burnt checkering - ain't no accounting for taste!
