I'm looking at a used model 12 in .223 at a local shop. 26" barrel blued, black plastic stock accu-tgrigger. Looks like a floor plate with two screws in front of the trigger guard that would allow the magazine to be removed. I looked on the Savage Arms site but can't find any info on this system or I'm not looking in the right place. What's the deal with the plate? Price is $450 OTD. Does that sound reasonable?
