Mk21 Mod0 M1919a4 7.62x51mm W/m13 Links

[Kenshi]

Can any one shed additional light on the story behind the Mk21 Mod0 US Navy Viet Nam conversion of the M1919A4 where it was barreled to 7.62x51mm and used the M13 link which was also used with the M60 machine gun?

 

Anyone on the board have one that they could do a virtual or pictorial walk around?

 

I am looking for any and all data including actual mil specifications, pictures, Mod kits, drawings, manuals, and personal commentary. Also a pic of how it was identified on the right side plate would be really nice.

 

Not much is really known about this version/mod of the iconic M1919A4 and what is commonly known would barely fill this page.

Here are three pics from the web that show a Mk21 Mod0. Look closely at the belted ammo and you can see the M13 links with the brass peeking through the open portion of the link facing up. The muzzle break was also singular to this Mark.

Thanks Dan,

 

You have answered one of the issues that no one had an answer for. That issue is how the side plate was identified!!

Hi all,

 

Some time has passed and I am happy to say that I have almost completed a drawing package of the Mod and parts necessary to turn a M1919A4 into a Navy Mk21 Mod0 gun alowing it to feed using the M13 links used in the M60 and M240 GPMGs.

 

I am lacking a couple of parts drawings in that package, the Mk21 Flash Hider, the rear belt pawl and the MK21 top cover belt feed pawl. Those parts are still being searched for. Here a two photos of a cut receiver section on a Mk21, one can see the link support on the right side, and the belt pawls and the round stop.

Using an Izzy 7.62NATO Top Cover and Feed Pawl, and the wider Izzy LH Belt Pawl AND the MK21 parts necessary to support the M13 links the gun feeds great.
