Converting a 16GA Stevens 620 into a 12GA, is it easy or even possible?

[Rsgort]

I don't know much at all about working on guns or how they function besides the minimums so please bare with me.

Now, what would one need to convert Stevens 620 shtogun in 16GA (or even 20GA) into a 12GA? Would it be something anyone can do on his dining room table with the necessary parts and a YouTube video for guidance? Or is it something any local gunsmith could easily take care of? Or is it more complicated than that?

Did the Stevens 620 ever come in 12GA? I've never see one for sale. If so are these 12GA models rare and/or expensive?

This is just brainstorming here. I don't plan on picking up and/or assembling a this scattergun anytime too soon. I am just seeking info for now.

I really like the 620 for it's takedown feature. Do any other shotguns have such a feature? That is a shotgun that could be set up for defensive use such as having an 18.5" barrel and an ammo tube with more than just a couple shells. I could cut to the chase by getting a gun set up how I want it right from he factory, that would save me time, money, and effort and really just be much simpler overall but I don't think I have heard of many other pump action takdeown shotguns.

Thanks in advance fellas, love this place. So much great info here from really knowledgeable folks!

Not possible

I have my dad's Stevens 620 and it is a 12 gauge. if they were made in 20 and 16 gauges I would say they were probably not near as many as the 12 gauge. all of the 620's I have seen were all 12 gauge

Not happening; learn to love your 16 gauge

Anything's possible if you have the cubic dollars. But why bother? I paid $100 for a 1920's 12ga 620 a coupla years ago. They're out there, you just gotta look.

Your gun was last made in 1953.
More then 60 years ago.

There are very few parts available now.
And if there were?

The cost of such a conversion, even it it was possible, would be several times more then the gun is worth.

Take-down shotguns are neither rare, or no longer made.
Almost any modern pump or semi-auto shotgun has an easily removable barrel and comes apart into two pieces in about 15 seconds.

Over & unders and doublr-barrels, even faster & shorter.

My late gunsmith used to say, "Any project is feasible if properly funded."

He also used to talk about "Stingray station wagons."

I wouldn't spend any more time thinking about the conversion if I were you...

There are a good number of 12 ga. 620s out there, best bet is to keep an eye out for one. There's also the non-streamlined 520 available in 12 ga., which (in its early versions) will give you an immediate visual clue as to its designer - especially if you compare the earlier 520 receiver with that of the BAR. If the double hump version is a turnoff, look for the later 520-30...

I haven't paid attention to the 16ga Model 620 but the 20ga for sure is built on a smaller frame/receiver than the 12ga unit.

I have owned both guns . I still have a 520 in 12ga and have seen the 20ga version of this which is also on a smaller frame as I recall.
