How to Add a Magazine Extension to Your Shotgun | Outdoor Jack

In this video I walk through the steps of adding a Magazine extension to a shotgun. The specific shotgun I am adding a magazine extension to is the ‪@GforceArms‬ GF1W 12 Gauge. The magazine kit I had to select is the Benelli/Nova Kit from Carlson's. Below are the steps in the full process:
1. Disassemble the shotgun Forend & Magazine Cap
2. Take out the Plug and Spring
3. Remove the Shell Stopper from the Magazine Tube
4. Check and Make Sure you have the Correct Kit for your Shotgun
5. Sand Down any Burs on the Inside of the Mag Tube
6. Place the New Carlson's Shell Stopped in the Tube
7. Put the new spring in the Magazine Tube
8. Replace the Forend
9. Screw on the Magazine Extension Tube

That workbench vice is dope!

[@OutdoorJack]

It really is. Makes working on guns super easy.

[@niallmcpolin2311]

​@@OutdoorJackwhat brand/model is it?

[@OutdoorJack]

@@niallmcpolin2311 The Brand is GForce Arms and the model is a GForce Refuge however they have a new model that includes a Mag extension that I would recommend. bit.ly/GForceOne

[@niallmcpolin2311]

@@OutdoorJack thanks dude

[@lenculpepper9150]

Good job! Filing that lip down on the inside of the magazine tube seems a lot easier than sawing the barrel off.

[@OutdoorJack]

Thank you, filing it down is key for sure.

[@antthefool7637]

Alright this looks simple enough, wish me luck. Thanks boss

[@OutdoorJack]

Yeah not to hard, holler if you need help.

[@CornhuskerCowboy.]

Good video... I just take the plug out my old Winchester for snow goose season

[@OutdoorJack]

Right on, I am guessing that gets you about 5 total rounds. This one will get me 9+1 and then I have 5 on the butt stock sleeve lol. 15 Rounds on the Gun.

[@CornhuskerCowboy.]

Ammo is expensive and sometimes hard to find. So I keep it reasonable.

[@CornhuskerCowboy.]

Any snows out west yet ?

[@OutdoorJack]

@@CornhuskerCowboy. Completely Understand.

[@OutdoorJack]

@@CornhuskerCowboy. Went out last night. Birds everywhere but none came to my pond until after legal shooting hours.

[@vicsmith4090]

If its a longer extension i use 2 clamps seems to work better

[@OutdoorJack]

That’s a good idea 👍🏼

[@Uniformrogue428]

I have the same shotgun but my stock is broken and I need to get a new one where did you get your set also great video

[@OutdoorJack]

Thank you, and you may be able to purchase a new replacement stock directly from GForce Arms. I would call their Customer service and see what they can do for you.

[@titoqwentezproductionz3406]

is there one for beretta 1200 ? thanks

[@OutdoorJack]

I am sure there is.

[@gremlin7599]

How careful do you have to be when going from 2 3/4, to 3, to 3-1/2, from buck, to high brass, to bird, to slugs, etc with a semi auto? I have a semi auto shotgun but hardly ever shoot it cuz i dont wanna hurt the gas system

[@OutdoorJack]

You know thats a good question. I don’t like to shoot anything but 2 3/4 and 3” but it shouldn’t matter if you issue general lubrications and cleaning practices.

[@joseramosdiaz2246]

Greetings, in what links did you buy to put the cartridges on the back of the shot guns?

[@OutdoorJack]

This is the shotgun Ammo holder on the butt stock - grovtec.com/products/buttstock-cartridge-shell-holder-shotgun-open-style

[@joseramosdiaz2246]

And will you have the video that you come out shooting with the extension?

[@OutdoorJack]

I did have some snow goose hunts shooting it. Not sure if I made a video of them yet. But I have not made a video just of shooting the gun with this build. I should do that. Thanks for the suggestion.

[@strycian]

Since that is semiauto isn't there a gas system or gauge that you need to set?

[@OutdoorJack]

Not specifically, some models yes. Not this model though.

[@user-of2dl8uw2w]

I'm looking for a mag extension tube for my SARS (Sarsilmaz, Turkey) 12ga. semi-auto shotgun. Can you help?

[@OutdoorJack]

What is the SARS model ?

[@frankarchibald732]

Wonder if it will work on a legacy sports puma 12 gauge ?

[@OutdoorJack]

Best thing there would be to take it to a dealer that has multiple mag extension tubes and ask them if you can try them to see what model fits.

[@frankarchibald732]

@@OutdoorJack hhmm. Good idea. Thank you.

[@davidpate2237]

I'm looking for one for a Mossberg 88 where did you find

[@OutdoorJack]

I am not sure on who would carry one for that Model. Carlson's is what I put on my maybe check here: www.choketube.com/

Hi im looking for a tube extension for a winchester sxp black shadow is that the same one you have? And where do i get it?

thanks allot 👍👍👍@@OutdoorJack

[@Tabajaraeloi89]

where can i find one for the beretta a300 ultima????

[@OutdoorJack]

I’d look at Carlson’s website to see if they have that. However i know some of those Beretta Models you can not Add a tube too.

[@92mylife]

Can i put ..mag extension tube to Retay shotgun

[@OutdoorJack]

Not familiar with that shotgun but I’m sure you can.

[@Hicks8907]

What kit is for this gun thought I read somewhere benelli nova but not sure

[@Hicks8907]

The benelli nova kit did not work on mine the threads were not deep enough

[@OutdoorJack]

So the Carlson's mag tube I used was the Benelli Nova/Super Nova/Beretta1301/CZ 712/912. Is that the same one you tried?

[@Hicks8907]

⁠@@OutdoorJackyep I bought the 10 shot it screws on a little crooked but goes tight just not tight enough the forearm has play and so does the barrel like 1/4” or more play my original cap has deeper threads then the extension does

[@Hicks8907]

Ok so just finally found another video on my shotgun it has a tappered end so I do in fact have to cut 1/4” off I’m going to try to do a spacer as not to damage the gun and see how it runs

[@OutdoorJack]

So I was about to tell you this exactly. Can either cut that 1/4 inch off or add a spacer. I found a spacer at my local hardware store that helped keep everything tight. I did just get the new GForce One that I upgraded to and it comes with a mag extension tube so I’m all set there 😁

[@davesmith3892]

Do you know of anyone that makes the extension tube for the Stevens 320

[@OutdoorJack]

This is soles based on the look of the shotgun but it may just be the Mag tube that’s for a REM 870. Here is a specific one I found - www.riflestock.com/store/product/stevens-320-2-magazine-extension-matt/

What length barrel and how many rounds is the tube?

[@OutdoorJack]

Barrel is 28”, and it’s a 10+1.

[@cocoloco2711]

@@OutdoorJack ahhh thanks. I have a 24" barrel so will go with 8 or 9 rounder

[@OutdoorJack]

@@cocoloco2711 yeah that would be a safe bet. 👍🏼

[@bobg3633]

I thought you can only have 3 rounds in the shot gun when hunting

[@OutdoorJack]

That’s correct most of the time. However there are some exceptions like snow goose hunting during the conservation order, and like hunting other species like predators. You have to pay attention to your local and federal regulations. Great question.

[@renelopez2244]

​@@OutdoorJack Exactly

[@johnsmith-lx9lw]

What did he read a book, turn the gun upside down and shake it or do the twist or shake it to the left and shake it to the right? hahaha,

Lol 😂
