Homemade 12 Gauge Slamfire Guns
All it takes is to Slam the pipes Together
Have you seen these slamfire gun? Basically, you have a barrel that is separate from the receiver, and there is a fixed firing pin at the back end here that sets off the round whenever you push the barrel to the rear.
Some survivalist preppers have experimented by building them with steel pipes. This fella from Royal Nonsuch Youtuber have created several variations, including this one that shoots a 12 gauge shotgun shell.
One of the downside to a slam fire gun is that its basically a one shot deal. Though there have been mocks that houses a hopper similar to the ones used in paintball. This particular is used as a repeater, but not one hundred percent reliable.
A basic way to shoot a follow up shot is to just pull the pipe (barrel) out and stick another round in the front of the barrel, and then you can go ahead and fire that, and it’ll shoot the empty case out of the end of the barrel, so you don’t even have to pull that thing out. See the different variation of slam fire 12 gauge below.

What’s up guys? Welcome to another episode of Royal Nonesuch. Today we’re going to be talking about the Slamfire 12 gauge, and I’ve been getting a lot of questions about all of my different Slamfire 12 gauges, so I figured I’d just kinda cover it all in one video. So let’s get this video started.
This is the first 12 Gauge we’re going to talk about today, it’s a slamfire type gun, of course, that means it has a barrel that is separate from the receiver, and there is a fixed firing pin at the back end here that sets off the round whenever you push the barrel to the rear. It’s really simple, I’ve done a lot of videos on these, and if you want to check ’em out, you can.
One really cool thing about slamfires is that, whenever you’re shooting, you can go ahead and shoot one– I’ll show you the trick here.
Alright, you shoot one round, and then– heh, the shots just raining down– you stick –oh we don’t want to shoot buckshot– you stick another round in the front of the barrel, and then you can go ahead and fire that, and it’ll shoot the empty case out of the end of the barrel, so you don’t even have to pull that thing out. It’s pretty cool.
So, see? All gone. Just keep doing that, you know?
This is kind of a special 12 gauge, I’ll talk about it a little bit. When I was down in florida with Mark Serbu, they parkerized it for me, and it’s got this really sweet finish on it. So, really happy with it, it’s a really really cool gun, it’s my favorite out of all my slamfires right now. But now let’s talk about a couple different slamfires that I’ve built also.
This is a repeating 12gauge slamfire, I’ve got a video out on it if you want to check it out, I’ll put a link in the description, but basically it’s a self-loading 12-gauge that is a slamfire that’s fed from the hopper up here. It doesn’t really work the best, but it does work. So check that video out if you want to see that. It’s a pretty cool gun, it’s really janky, but it works.
This is another slamfire, it’s a 12gauge grappling-hook gun, and I’ve done a video on it also, it’s a really fun video, I might make another one in the future, but basically it’s a little different, it’s got a bolted-in breachblock, and it’s just– it’s probably one of my safest and strongest slamfires, and I had to make it really extra-strong because I’m shooting like, a three-pound projectile. But it shoots this grappling hook, it’s a really really fun gun to shoot. And actually, we can shoot it now if you want to see it. It’s a little rusty, but at least I can pump a round in there and show you. Can’t shoot the grappling hook today, because I have to actually make up specially-loaded rounds for that, and I haven’t made any yet, so…we’ll just have to make another video for that. But yeah, this thing is rusty as all getout. I’ll just shoot it off real quick.
Oh man. Look at that rust. I need to really clean this gun out. I might not be able to shoot this today, I dunno…
There we go. Ugh. All that rust just came out of the barrel and blew into my face. But yeah, this is a fun gun to shoot. Let’s go ahead and shoot the other slamfire, just show you what it can do.
Alright, let’s see if we can get a first-person view of this… I’ll shoot it at one of the targets down there.
There we go. Heheh.
Alright, now let’s see just how fast we can get off two shots at those shoot-steel poppers behind me.
Alright, here we go.
You can also shoot slugs and buckshot through these, so we’re gonna go ahead and take a shot at about twenty yards at the red shootsteel target, and just see how she patterns.
Hoh! That’s just the wad, it came flying back. Let’s go look at the target!
Well it looks like we patterned pretty good. Those two shots were already there, we hit right here in the top part of the target, so. Not bad for a homemade gun! It’s pretty darn good.
Another awesome thing about slamfires is, since they have a three-quarter inch pipe barrel, you can do things that you can’t do with a factory gun, so you can do things like an inception shotgun round. Shoutout to MattV2099 and all his 2099ers out there. ‘Cuz this stuff is just hecka cool. And by the way, that 20gauge is loaded. I think we might wanna just step back a little bit. Alright let’s step back.
That’s better. Alright, let’s go for the middle ShootSteel green target.
That’s pretty cool!
And look at what it does to the 20gauge shell! That’s awesome. I made a video on doing this completely throughout the video, and it’s a really cool video, you should check it out.
Well in conclusion, these are really really fun guns to shoot, they are 100% legal, I’ve gotten pulled over with these in my car and they’re all good, so, really fun guns, totally legal, they cost– this one probably cost me around $20 to make from the hrdware store, so it’s just a really simple and fun gun, anyone can make ’em with pretty basic tools, so thank you very much for watching, everyone, don’t forget to subscribe, and I will see y’all next week.
