Most Helpful Positive Review They don't tell you...
I purchased this extension for my Henry 17HMR as I had installed a scope on the receiver. This extension definately made it easier to cock the hammer as the scope is very close to it. I was shocked to read in the directions for the extension that they recommend you file or grind a groove for the s...

Great add on to my Marlin 335W

by DJ, Verified Owner from TX, United States Written on August 26, 2017
This item really helps with a scope mounted to my Marlin 336W. It is strong and well built. I like that I can install it for right or left handed use. Easy to install remove. Need to make sure your Marlin was built 1987 and newer for this hammer extension to work on the hammer.
Pros:
  • Well Built and Solid
Cons:
  • None I can think of
Best Used for:
  • Marlin 336W

Mike's Hammer (extension)

by Legacy Reviewer, from WA, United States Written on May 15, 2011
Easy to install extension. I find the round knurled barrel of the thumb contact point to be more comfortable and easier to manipulate than the other flat ones that are out there. Just make sure you order the right model to ensure proper fit.
Pros: Simple, easy install, solid
Cons: None yet
Would recommend: Yes

Uncle Mike's hammer extension

by Legacy Reviewer, Verified Owner Written on December 19, 2010
This hammer extension is perfect for those hunters who would like to mount the scope low on a Marlin 336 rifle. Without this item, a shooter cannot operate the hammer manually unless the scope is mounted very high. The texture of the extension is rough and grips your thumb very well. This item is very functional.

Just be sure you order the correct one for your rifle. Older Marlin rifles had a more narrow exposed hammer than the newer ones.
Pros: durable and functional
Cons: just be sure you get the right model (early/late Marlin)
Would recommend: Yes

Hammer Extension

by Legacy Reviewer, Verified Owner Written on September 20, 2010
You don't find out until you open a sealed container that it is NOT to be used on Winchester Model 94's with hammers that are fluted or knurled even though all ads say you can. ALL 94's for the past 100+ years are made this way!! Bushnell, the distributor, does NOT get back to you even after 3 phone calls. Dangerous to use in my opinion.
Pros: Well made
Cons: Does NOT fit Winchester Model 94's as stated
Would recommend: No

Hammer Extension Problems with Model 94 & Scopes.

by Legacy Reviewer, Verified Owner from SC, United States Written on December 30, 2009
Basically. Other Hammer Extensions work much better on the model 94 if you have a scope on it.

They are simply machined to inexact tolerances and are ill fitted. Since the Model 94 has a "Drill thru" hole on their hammers...this is the proper spot for mounting one of these, one that GOES THRU THE HOLE for safety and tightness. These Hammer Extensions have a allen nut on the extension side only that you tighten down against the hammer.

Very poor design and actually not all that safe. Find a "drill thru tye that fits right thru the Hammer hole...and you will be much happier and safer!
Pros: It should be a safetey and comfort issue with a lever action Model 94.
Cons: They don't fit the hammers all that well, and if you have a scope, you must be VERY VERY careful on the use of these. I had to remove mine because it brushes the scope and it is easy to slip off your thumb because of the poor fit.
Would recommend: Yes
