Safely attach 16ga shotgun to rails

1035 Views 14 Replies 8 Participants Last post by  Sallison
I'm wondering, if all the correct paperwork is done and all legal measures taken, could my attachment rails handle the kick of a 16 gauge shotgun? I have always thought the masterkey idea was cool and think it'd be a great project. I have a bolt-action 16ga that would be perfect for the job, and my Kel-Tec SU-22 is the rifle it would first be attached to.

Hard to understand what rails you're describing. Can you post some pictures?
The forend rail is held on by a little thumb nut that holds it tight to the base of the barrel. I can take some pics close up on it if you wanna see.
So SBS the shotgun then mount ? Not sure on that the masterkey use the barrel and the forarm to mount ala 203 laucher


I mean if you want a masterkey you can legally buy one pre made as a SBS

I'm not a big fan of the actual masterkey, the pump seems like it would be bulky. With a bolt action it could (maybe?) be a lot lighter. My plan is to attach rail mounts to the top of the shortened shotgun so I can attach/remove it easily
You can do about anything you want these days for attachments. The weight is what would kill it for me. Get you a pump shotgun with folding stock and sling it across the back until you need it.
I've certainly performed my share of what I initially believed would be "cool" projects. Yet, IMHO, this one sounds like a really good way to...wreck both your KelTec AND your 16 gauge. Fun in theory, disasterious in fully-executed reality. Again, I'm no expert, but I do still have...all my fingers. :biggrin2:

Good Luck!

So what exactly do you think would happen if I tried it? I'll admit the more I think about it the idea just sounds worse & worse. It would probably be twice as heavy as the rifle itself.
Best research the legal requirements of short barreled shotguns , ect before starting this modification.
I think some projects are best left on the drawing board :smile:

What I "exactly think" is that KelTec never engineered that particular stress-load into the specs of that rifle (meaning just the increased WEIGHT). That's not counting the shock-load of the 16 gauge recoil. Responsible firearms manufacturers have staffs of well-educated, experienced engineers, rooms of AutoCad stations, and safe facilities to destructive-test their concepts all the way to...KaBoom!

You have one rifle & one shotgun. I just advise that you not jump straight to the...KaBOOM! :biggrin2:

Mighty kind of you R&G! Will you drop a note to...Mrs. GT? :biggrin2:
Well everybody, I thoroughly appreciate the input. I think I'll take Bandit's advice and "leave this one on the drawing board".
