the gun is PERFECTLY USABLE in its current condition ,matter of fact it went hunting this year and bagged an elk, got a custom built rail and a new vortex optic utilizing the side mount drilled and tapped holes from the factory lyman tappings no drilled rear reciever top so its not NEEDING a change but... that 3.6" mag well is BEGGING to be a more usable caliber BUT its got a 4 didget serial number completely unadulterated and fully functional... so im actually with SDPLINKER BUT then again..... it WILL NEVER be sold BUT....... then again...... its BEGGING to be a 33+ caliber
