Video is uploading. should be done pretty soon though.

GP13 delivers. I don't have software for a proper audio analysis, but a friend of mine had builds ranging from 35-50 rps and they sounded very similar.
Good stuff man.
Notrabies how's the shotgun coming?
[QUOTE=Ccharlton;38351671]Notrabies how's the shotgun coming?[/QUOTE]
No progress yet because I've been busy lately. I'll do some work either tomorrow or Thursday.
Thanks dude, sorry my trigger finger is getting itchy, because I scored expert in Korea on my marksmanship I don't get to go to the range tomorrow :(
Notrababies will you post a build log the new shotgun? List off all the things you did, materials used, etc.
Uhh sure.
Maruzen M1100 Revision
G&P Mad Dog grip
Modified extractor
Schaap prototype shell lifter
4mm inner diameter 6mm outer diameter macro line
gas line quick disconnect

Oh wait a minute, looks like you're asking this notrababies guy for advice, carry on.
Ever thought about making a SAIGA?
yes
it's not feasible with the maruzen system
[editline]9th November 2012[/editline]
saiga is not an acronym
[QUOTE=YCheez;38390555]Ever thought about making a SAIGA?[/QUOTE]
Wow, you have all these great ideas! Maybe you should be the one building shotguns instead of me!
But seriously, look at a Saiga and look at an M1100 and think how much work would be involved in turning one into the other. Then look at the Maruzen internal parts diagram and tell me how you can make a magazine fed shotgun without an actual chamber and bolt.
Nobraties have you ever considered making a belt-fed shotgun?

I would imagine the Magazine would be easy to make but getting everything to actually work properly would be complicated as fuck.

Not even close. On a real shotgun or other semiautomatic system, the chamber sits forward of the magazine, and a shell is pushed from the magazine into the chamber by a bolt. In the Maruzen, the chamber is directly above the lifter/loading gate, and as a result the bolt only moves a few millimeters.
Since the bolt is only moving a very short distance, shells would not clear the magazine tabs, so any existing magazine design wouldn't work, plus you'd need to somehow integrate a magazine release into the gun.
Well based off your experience with maruzen m1100 internals do you think it could be possible to create a saiga? To me it seems like a magazine would be fine if placed farther ahead of the trigger, allowing shells to move from the mag into a really short tube. From there it would function like a normal m1100.

velcro mag release
pull magazine to take it out lmao
push in to put in

Absolutely not. How is a shell getting pushed from the magazine into the magazine tube? How is a shell being chambered while a magazine is in the way of the lifter? How is a magazine even staying in the gun to begin with?

The mag would act as an extension of the tube. The shells would enter the tube area, which would be shortened to carry only one shell without the magazine. When the shell enters the tube area the gun functions just like an m1100. Basically the gun becomes an m1100 with an extended mag. As for keeping the mag in place I think an ak-style mag system would be ideal. If the shells used by an m1100 are the same in proportions to a real steel 12-gauge shell then one of these mags should hold them. Given your machining experience I think you could cut a hole into the tube, create a hole for the mag and the ak mag holder lever.

i tried to read that and i dont even
(the maruzen shells are different sized than real shells)

Well then could a real steel mag be somehow modified to fit them?
Okay, ignore the Saiga idea for now.
Let me ask you how a shell goes from the magazine tube to the chamber in an M870.
Once you figure that out, you'll see why you can't just go throwing magazines wherever you want.
What about my brilliant and innovative belt-fed mashotgun idea? :downs:
No, what I'm saying is that the mag will be attached to the tube, and the shells from the mag will feed into the tube. From there the gun will function exactly like an m1100, the shell will be in the tube until it is moved into the firing chamber (or however m1100s work). The mag will not effect the internal function of the gun in any way. It will be essentially an extended tube.
[QUOTE=Apache249;38391226]What about my brilliant and innovative belt-fed mashotgun idea? :downs:[/QUOTE]
Its sad to say that its more feasible than anything else so far. If I could think of a way to have the belt disintegrate after firing and before the bolt door closes, as well as a part to move a shell into the chamber, you'd be set.

So how does a shell get pushed into the magazine tube, or from the tube into the magazine, or how does the magazine tube spring get pushed back?

notice how the mag tube extension is towards the [I]front[/I] of the gun
How does that work? Standard Extended Magazine size, so like 7ish shots or something? Than after you've shot all those off you have like three shells in each tube to select? Total of 16 shells~?

14+1 for compact 22+1 for full size
from vidyas on the jewtubes apparently you can dump the entire 23 rounds without manually cycling the tubes or anything

If I was to commit a murder, this is totally how I'd do it. Empty 23 shells of buckshot into my victim in under 30 seconds.
Try to connect these dots motherfucker.
