Well even if it were a part of the stock I still would go with the limbsaver pad . Have a look your self Has it screws on the back then take these out , tape the end of the stock, get something to gently tap it off.
Even if the gun shop charged an hour labour it would still be worth the money.
It made my T3 shoot more like a 30/30 Marlin than hitting the shooter with a hardwood section of 2x4.
