This Winchester manufactured fourth variation action slide is for the later model 12 slide action shotgun in 16, 20 and 28 gauge and is in very good condition with light wear. (file photo)

Note: Winchester model 12 slide action shotguns with the following gauges and serial numbers have been observed with this part:

Note: We believe that the fourth variation action slide will NOT be interchangeable with the previous variation action slides because the fourth variation has a different cut in the walnut forearm.
