Very sloppy on a Marlin 336 The package says it fits a Marlin 336 lever action, and technically it does, but it requires modification. The slot that your hammer spur goes into is way oversized, so make sure you hold the extension in place while you tighten the set screw, or it will be off center. In stock configuration, the action will not work, and the hammer will not cock, with this in place. The instructions tell you to grind it down to clear the 336 if you have a crossbolt safety. Product is made in the USA, which is a big plus, but I don't like buying something I have to modify to work for my application. For the price it may be worth it to you. October 29, 2011
Works great I installed this on my Henry lever action .22, after I realized I couldn't get to the hammer with a scope on the rifle. Fell of the first time is went out shooting, but it was my fault I didn't put any thread lock on it. Remedied this issue and have not had a problem with it. January 6, 2015
Hammer Extension Works great! Wonderfully constructed! Allows right or left hand shooters the ability to cock hammer easily. January 12, 2015
