The Model MB 750 wolf trap has been upgraded by C&S Sales in Victor Montana to a model designated by C&S Sales as: MB 750 Alaska Wolf Rig Modified or: Model MB 750 AWRM. The upgrade addresses some issues that trappers have experienced with this excellent trap. The upgraded model features a new bracket on each side that acts as a brace to prevent the trigger from being bent & stops chain tangle. The pan tension bolt has been replaced with a stronger stainless steel Allen head cap screw for 10 pound pan tension. The upgrade also feaures chain upgrades including welded j-hooks, a heavy duty wolf swivel, new heavy duty shock spring and a 5/16 heavy duty quick link.
