Light machinegun use in small teams? - Page 2

Blow back systems I know of use pistol type ammo. Recoil is for Hy-power stuff.

I wonder if you played with the various inners of those firearms?

Guns to look at; 1919, MG42 (or variants), M60. For blow back M3, Sten, Thompson.

Recoil can be a issue, so weight or a recoil compensator is necessary for the bigger rounds.

The M14 was uncontrollable on full auto unless one burst it to ones to 2 or 3 rounds max. I guess with a compensation it could become manageable at more sustained rates.

MG42 has 50 rd drums for linked ammo. I don't think hoppers would be practical, unless in a static environment. Bouncing around in a vehicle would upset the "load".

The design difference in feed of the MG42 over the 1919 added to it's much higher rate of fire.

Then the other options are, Open bolt Vs Closed bolt.

Well, being a big fan of John Browning my design is based off the 1919a4. Im looking at fluting the barrel or ribbing it to aid cooling and lighten it. My hopper idea would feed from the bottom and use a geared operation off the recoil to feed it. I don't like the idea of using Aluminum with .308 I think it is just not safe and can't hold up to the pounding. Those links you have 7624u are very good thanks.
Hollis, I have messed with the internals on the 1919 and Im currently building a Semi Auto MG42. There is a lot mods involved to meet BATF standards. My idea stems from working on and building various military firearms. The design I have incorporates using as many surplus parts that are easy to come by and cheap. Which includes mainly 1919 parts, MG42 (GRIP STICK I like the angle of the this) and the FAL.
Supposedly, in WWI I think it was the Maxim that they did a sustained fire of 10,000 rnds with. I doubt many of the designs today could handle that.

The design I have would use a feeding ring I call it around the barrel breech where the rounds would be stripped from and then loaded upon return of the barrel in the forward position. This would start the next cycle (closed bolt operation) like a 1919. I would like this system to also function as a sniper platform as well as a firesupport weapon. After, this MG42 is done I plan on starting to make parts for this and seeing just how many hours of work I get into with that. It may just get to the point where it becomes to expensive to make for a one man operation. Lastly, the barrel change if need be is very quick and simple on this, it is a lugged lock in, with 2 cross pins similar to the M60 and no the coned booster will not have to be taken off.

MG42 has one of the slickest QC barrel designs available anywhere.

I agree, it is the best I've seen and operated.
There is a guy that is working on a carbine version of the MG42, that looks very interesting. Having a MG42 that short would be neat to shoot I think he has the barrel length to 16".

If it is possible could you send me (PM or email) the info on converting a MG42 to semi?. I have already converted a 1919.

Thank you. H.

No problem, I just happened to kind of fall into as another project and have found some good info.
I sent you a PM the site is of great help.
