Thread: Model 60 tube mod.

In light of my Marlin Model 60SS being restricted, because it has a 14 shot tube mag, I am seriously considering getting Gunworks to make it compliant. I know there is a slim hope of the unintended firearms, such as 15 shot lever .22s etc, being allowed, but do you guys think the same would apply to my semi, or shall I bite the bullet, and get it done?

bite it and get it done......or do it yourself.

I'm getting a mod done to my Marlin 60 right now with Greg Maniatis here in Christchurch - $80. Drops it from 14 to compliant 10 shot mag.

That beats $210. Do you have contact details?

Shame you can't get it rechambered for .22WMR, would take the magazine down to 10-shot capacity.

I'd do it in a heartbeat.

As others here have already suggested, I wouldnt touch it until you know what the next law reforms are going to bring and there is a clear definition on what the requirements are. I wouldnt be totally surprised if they turned around and allowed tubes up to 15 and just limited removable mags to 10 on .22s now they have had time to actually look at them and know what the difference is and not just do a knee-jerk cross the board ban.

For a semi, it is a difficult thing to do. The lifter needs to be able to cope with the longer shells, then there is a need for a heavier bolt as just putting in a heavier spring is not sufficient. How does one make the bolt heavier?

A web page giving an idea of the formula for bolt weight required: https://orions-hammer.com/blowback/ but I get a figure of twice as heavy a bolt being required (0.82lbs for .22WMR vs 0.4lbs for .22LR) for similar initial bolt movement rearwards. Not to be compromised on as it is a higher pressure cartridge, the poor way of doing it is with heavier return springs but that is hard work on the gun's innards.

But alas, ten rounds of .22WMR is ... ten rounds of .22 WMR. A better outcome than what you had before... if it IS possible, that is.

Just a dream Would love a model 60 in 22 magnum.

Yes - I thought about the option to wait but didn't want a Police squad at my door one day enquiring and taking away my wee Marlin - plus other arms for non compliance! Some strange over-reactions happening these days. They may amend the new law - and should - but I doubt there is political climate for it at the moment.

Decided to do the small alteration with Greg Maniatis. Makes it legal at 10 shot and no real loss with the rifle. 5 years ago we'd pop over 1000 bunnies a night in North Canterbury, but those days are gone. Now you'd be lucky to use one tube. 10 will do for me. Greg's number in Chch is 0274879611.

Yep a 60 in 22WMR could be fun. Marlin did try a .17 cal semi but that didn't work well - a 17M2 model 717. Case splitting and other probs - wasn't round for long. I think??? Savage made a semi too in 17HMR and it also was not a success.
