Glenfield Marlin model 60.

I am working on an older Glenfield Marlin Model 60. It has the new cartridge feed parts put into it as the owner has put thousands of rounds through the firearm. The recoil spring and guide are original parts and straight. The rifle has given good service until recently. Now the gun jams every shot with each new cartridge stove piping in the receiver, bullet towards the breech, and the cartridge rear raised rim to far wall. The rifle cycles fine when worked manually. Does the cartridge feed spring lay on the bottom of the cartridge lifter or in a notch on top of the lifter? Outside of the replacement cartridge feed parts the rest of the rifle is original.

The Alaska Commercial Company Store here in Dillingham, AK sel Is many new tube-fed Marlin Model 60's. I keep telling the store manager to buy the clip fed model as the outer tubes bulge at the seam when people attempt to load too many cartridges, causing the inner tube assembly to go flying off, sometimes into lakes, rivers or saltwater or mud, sand, gravel. People blow into the outer tube in the winter months in their attempts to make tube go in or out. As a fix, I polish the hammer/bolt contact area and the hole where the recoil recoil spring and guide lives and sometimes apply bedding compound to one or both takedown screw areas to make guns work in the cold.

In the April 2005 issue the article 'Avoiding Mistakes with the Marlin Model 60r' appeared. There may he reprints available from the publishers office. If not, we're including your email address so an AGA member with a copy of that issue can arrange to photo copy the article and snail-mail it to you.

There are certain areas in the article and in Marlin Firearms: A History of the Guns and the Company That Made Them by Lt. Col. William S. Brophy USAR--which is considered by many to be the Bible on all things Marlin--worth mention now. Among the items we discovered in preparing the article and related to yonrqnery were:

First, the entire action of the Model 60 and its clones is contained between two plates retained by E-cIips. The factory employs a proprietary jig Jor assembly, lake down and replacement of components to prevent about half the action springs to fly away. A substitute for the jig was used and is pictured in the article.

Secondly. Marlin 60 and Glenfield 60parts are not "drop-in" interchangeable due to the wider receiver of the Glenfield. An example is the feed throat.

Thirdly, the Marlin 60 was not produced with a clip feed. These models were the Marlin Model 70, Glenfield Model 70 or one amongst the Marlin 995 series.

As we recall, the lifter spring expands after compression. As such, it will not function properly when merely placed upon the bottom of the lifter. Ergo, it rides in the notch to apply upward pressure. You may want to double check this placement out with Marlin but an answer would probably only apply to currently produced Model 60s. We don't believe, however, that an engineering change has not been made for many years.

The bulging seam problem is definitely owner created and such owner has to pay for a new tube assembly-while not ever forgetting to lock the inner tube within it via the long-practiced, highly complex and physically demanding I wist of the locking cap between thumb and forefinger. Said owner might be further advised to avoid blowing a frosty breath into the mag lube. The tendency can transform the frosty breath into an icy sludge, making removal that much more difficult. Closer attention to lubricants, meaning avoiding those that stiffen up in very cold conditions, are to be reviewed. We suggest a silicone spray but not too heavily applied.
