Can you see how to install a guide spring on a Marlin Model 81 dl 22 caliber rifle?

Answer 1

I assume you mean the cartridge guide spring. You will have to remove the barrel to replace the guide spring. The barrel is retained by a cross-pin through the receiver. This is a tapered pin and should be drifted out from the left side of the receiver to the right. If the barrel is tight in the receiver after the cross pin is removed, set the barrel in a padded vise and drift the receiver off to the rear using a nylon, or brass drift punch.
