Marlin Rifles are great bits of kit, however as with a lot of rifles, they can seem a bit rough at first. One of the best things you can do with a new rifle is to shoot it! Continual cycling of the action will allow the parts to move, and wear in. This will remove and burs left from manufacturing and smooth up all the parts. After a few thousand rounds you’ll really notice the different.
The standard trigger on Marlin Lever Action rifles is ok, but not brilliant. Wild West Guns have a solution to this, in the form of their Trigger Happy Kit. This simple drop in trigger kit removes the annoying trigger flop, and gives a light, crisp trigger. A good review and installation guide can be found here.
Wild West Guns also produce a “Bear Proof Ejector” which is an EDM cut one-piece ejector giving reliable ejection with even the heaviest hunting loads.
Marlinspares.com produces a stainless steel follower, to provide smoother feeding, and better reliability.
Marlin Lever Action Rifles can also be improved by adding Wolff Reduced Power Springs. This simple kit comes with a new hammer spring (mainspring) and finger lever plunger spring, both of which are reduced power. By fitting these springs you will reduce the force needed to open, cycle, and close the lever, thus making the rifle smoother to use.
Single Piece Firing Pins also prove popular with people looking to improve the function of their rifles. Standard 1894 lever action rifles have a two piece firing pin. The idea behind this is that the firing pin is unaligned (split) until the action is completely closed, so if the hammer was to drop with the action partially open, it could not fire a round. The downside of this is that when closing the lever, extra force is required to push against the spring, and align the pins. This split pin design is a safety feature of the rifles, however many competition shooters feel this is redundant, and so install a single piece pin to smooth up their action.
