Flapper-Locking Firearms

[@fudgerounds91]

You are literally the only source Wikipedia cites for their generic flapper lock page.

[@somethincreativ]

Easily one the the best firearms channels on youtube!

[@N3kr0n15]

and just to show that there is nothing new under the sun: I've been working on my own fire arm design for a while now. it was important to me that i don't copy or clone one that already exists. i found one that works (on paper) and then i see that not only it was already done 100 years ago, it was posted 6 years ago on a channel that i started watching 2 years ago.

[@jamesgornall5731]

There's nothing new under the sun eh?

[@justinswinehart5361]

Just curious but how is your firearm design coming along?

[@N3kr0n15]

@@justinswinehart5361 honestly, life happened and priorities changed. Started to get the money for a milling machine and my state banned "ghost guns".

[@landenjones9374]

Yeah can I ask why it was so important to you to design something that's never been made before because no offense but that's just kinda dumb and also impossible

[@AsbestosMuffins]

wow ian has come a long way, especially camera work

[@christopherwarman2870]

I love your videos I’ve watched your content for years and you’ve never lost that fervor and dedication to the mechanics of firearms

[@tulius01]

This flapping locking system might have it's merits in a manually operated gun like a straight pull bolt action where there is no problem of case head separation on extraction due to a hard strike on opening the chamber.

[@SPAZTICCYTOPLASM]

Yea but then it has no primary extraction, which isn't great when your ammo is dirty. See guns like the ross rifle.

[@RGD2k]

Really appreciated the exploration of the weaknesses and flaws of the mechanism in this video.

[@danielhandika8767]

Man, I thought I was going to be an inventor of this kind of mechanism but it turns out that it has been existing for a long time

[@svtirefire]

Haha man I hate it when that happens. I remember when I thought I'd invented the opposed piston engine.

[@whyareusobad3528]

@@svtirefireI forgot the name of the gun but I designed a semi auto conversion for what was a straight pull rifle I saw in a video game I then learned that that same gun actually did end up being converted for semi auto and full auto fire

[@MUCKLEECH]

Awesome, thanks for the great vid. I've learned a lot from the channel, PLEASE KEEP IT GOING STRONG:D

[@TheBlandetgodt]

Thank you for another fantastic video, and merry cristmas from Denmark :D

[@dentonwarn3883]

The Winchester 150 lever-action .22 and its pump-action twin from the 60's utilize a locking flap on top of the bolt. They are rather cheaply made, and will not hold up like earlier designs.

[@damattalizer]

very insightful observation

[@daskro]

Great content and good video quality!

[@kenhelmers2603]

Nice explanation, thanks :)

[@seal7144]

I like the flapper lock system on the Mauser 06/08.

[@sionsoschwalts2762]

MG51... the Rolex of MGs. Developed from the MG42.

[@Jesses001]

Very interesting. Reminds me a bit of the rolling lock system. I would prefer the rolling lock system though, haha.

[@Possumliving]

I think the Colt-Sauer bolt action sporting rifle used a flapper lock.

[@leojacinto8407]

Please sir do a review on the Reiger Mechanical Repeating Pistol.

[@toods2]

Neat! Thanks for the video.

[@ClickerQuiz]

thanks for making this video. Are you ever going to make a video about the RPD?

[@erg0centric]

I think Savage A17 (and 22WMR) use a single flap that rises into the receiver. 22LR is simple blowback.

[@rainwoods4383]

How does it unlock when paired with a short recoil system?

[@4ffff2ee]

is ian immortal? this vid is 11 years old and he hasn't changed a bit since then. is he actually jesus?

[@USALibertarian]

How does it unlock?

[@RealCadde]

+USALibertarian IIRC these are gas operated weapons. The gas pulls the pin out and then the bolt. But you should look at the video for the 43.

[@paulpolito2001]

Am I the only person that thinks “Locking Plates” or something equivalent would be an improvement? Since imho, “evoking confidence” is something your Firearm Locking System should do almost as well as keeping the deadly bits flying away from one’s person.

[@MrM2hb]

Good vid.

[@janostoth-zf2hk]

Would this work with a short stroke gas piston?

[@stevegable2707]

flappers are a bit like the roller design or the roller non rolling H&K I think it is ?

[@warfilgames]

i'd like to see more vids on early firearms

[@Supersaiyan79]

I just subscribed to your channel. Your videos are interesting and informative but please, please use a tripod when filming and don't use material that is out of focus. Good lightning and camerawork will help to see the gun assemby better.

[@stuart6454]

What causes the flaps to come out of lock after a round is fired?

[@melted8368]

The gas from the cartridge pushes the gas piston and the gas piston pushes the bolt carrier backwards making the bolt to unlock.

[@fortnex9972]

Kinda roller lock! I sayd kinda!!!!

[@Suomipanzerdiv13]

But had they put that large flappers on a g43 the rifle could have been less controllable.

[@ChrisPenta]

A weird offshoot of a roller locking design.

[@wierdalien1]

Christopher Penta flapper lock is older than roller delay

[@CafeLibrado]

is that a tec-9 there on the shelf?

[@robertkubrick3738]

M-85 .50 BMG coaxial?

[@BigHarryBalzac]

@Stanley Jedrzejczyk I used to work on M85 machine guns, first from M60A1 tanks in CONUS, then M60A3 tanks in Europe. The old Ma Deuce wouldn't fit in the cupola so they put the M85 in. They didn't have room in the M60A2 tanks to open the cover to load it, so they switched it to right-hand feed and turned it upside down! Other than the sears wearing we didn't have a lot of problems with them, and those were an easy fix. Sometimes I had to replace worn flappers. I think they were actually called bolt locking latches or something like that, but I called them wings because they flap. Occasionally a time delay roller would need to have the spring replaced, or just preloaded after someone who had no business messing with it took the roller out. We had several bad solenoids to deal with too. @ Robert Kubrick The coax machine gun I worked on from both of those tanks was the M240. It replaced the M73 and M219, which most people said were the worst machine guns the army ever had. But our platoon leader in Germany used them in Vietnam and he really liked them. They look like a small breadbox (if anyone knows what those are) with a jacketed barrel sticking out of it. They eliminated some parts from the M73, simplified it, multiplied the model number by 3 (73x3=219, voila!) and it worked better with some parts missing. At some point they tried using an M60E2 for a coax machine gun but I've never actually seen one of those.
