Grendel LMG

[stanc]

If I push it, he seemed open to doing it actually. He would need gauges, a reamer, NO-GO/GO, etc.

So, are you gonna push it?

I learned recently that there is an 07 FFL holder in my area who does modifications on existing machinegun designs, to include an HK fire control group/grip on SAW's, Mk46's, Mk48's, etc., as well as caliber conversions on them. I think they would be the best route to take with this project.

I was looking at old pics of guys in SOG who carried the RPD for its lightweight, compactness, and firepower.

Sounds promising. I wonder if they can give a cost estimate?

I have to tell you how impressed I am with the handling and balance of the RPD. It's been a while since I played with one, and it is very slim, light, and about perfect for an LMG.

I also saw something really cool from Tango Down...an AK quick barrel change system with an interrupted thread system, and a detent protruding out of the barrel trunnion. It would be cool to use that design on the RPD so it has a barrel change feature.

Interesting. Sounds suppressed, intergral suppressor maybe? But that's a lot of rounds to carry and expend! Very nice.

Did we lose the video file?

Still works for me.

OS X update...had to reboot. All works now...LOL. Thought the spammers had struck again...

Nah, just poor sound reproduction. That's quite common in videos such as this.

I'd like to see the negative characteristics of these back pack systems. They never show us that.

+1 I bet it's heavy as hell.

Cool concept though.

I coulda sworn there's a video of Gene Stoner himself, from the '50s, wearing an ammo backpack and firing an LMG in exactly the same way. OK, hell, gimme a sec to Google it. . . . OK, got it.

Yes indeed. But, we already knew that from the terrific work done in late 2011 by RangerRick, and his posts on pages 6-7 of this thread.

While it would be great to see a Grendel LMG even if it feeds from RPD belts, to have the slightest chance of being adopted by the US military will require disintegrating links.
