View Full Version : Need .223 Belt feed help
06-30-2011, 07:03 PM
I cannot seem to find a .223 M249 top cover short of buying a full M249 kit for $4500.00 (not gonna happen). Guys is there any other feed cover out there that will cycle M27 .223 metal links? One that can be modified? I want to finish this semi-auto project but am stumped for the time being.

I think you are going to have a tough time. When I was building my MG47-308, I learned the trick to all of it is matching the links and the feed mech. If they don't normally work together you will have a tough time. You may be able to mess with an RPD cover, but it will be a challenge. Perhaps if you can tweak the RPD belts to hold 5.56, it could work, but I think that is the reason that no one is building them.
If you find a cheap source for 5.56 feed mechs you will open up a big door that we all will go running through.....

Found this, but it's cut and doesn't seem complete.

Any other 223 belt feds that you might be able to use parts from?

Perhaps a Stoner 63 or US Navy MK23 version top cover can be found surplus from the Florida vendor, Reed Knight. Or.. adapt airsoft pieces of the MK 23 from http://shop.ehobbyasia.com/gandp-u-s-navy-mk23-mg-stor
Those airsoft replicas look amazing. See pic of the airsoft. It's all metal by the way.

This is a great question. If someone does find a top cover that will cycle 5.56, please share.

artty thanks for fixing the link :)

That link shows a 7.62 x 39 belt. Is that correct for the smaller round?
11-17-2011, 03:35 PM
yes. on the rpd type (U) links you can insert the round backwards . you will need to put the starter tab on the end of the belt.

done a quick check on what i can fit in the rpd type (U) links . 30 carbine, 7.62x 25, 5.45x 39, and 9mm .

@cal70 - I have read several discussions, in the past, about the use of type (u) links. I never could find where these were available. Thanks for clearing this up. So, if you wanted to do a 5.45 or 5.56 cal MG47, you would use a RPD top and tray with the type (u) links?
Thank you for the info!

I'm pretty sure a .223 is to long for an RPD feed Tray, you would have to mod it somehow.

Didn’t think of that @ Dark Knight. I was more excited at the diameter issue than length. Wait, that didn’t sound real good, but you get my meaning. Thanks.

I'm pretty sure a .223 is to long for an RPD feed Tray, It is.
And the 223 is too small in diameter to work in the link, both ways.
11-22-2011, 08:33 PM
guess im wrong on the rpd feed tray .the length being 2.244 and the 223 being 2.223 . not enough wiggle room? :(
11-22-2011, 08:48 PM
running the rpd belt backwards ,bad idea on my part. why? the bullet stop has a ridge that runs between the link and bullet and may jam. :( solution. needle nose pliers to bend /compress the link to fit the 223 round. :)

You should be able to take some metal off the feed tray? I'll try to get more details later to give you a better idea.
It's hard to say if you can bend the links in more, they are fairly hard and not springy like you'd think. I found this out on one of my belts because there's a tab like thing on the front of the belt that rides on a guide to hold the front of the belt up in the feed tray, one was bent and was jamming, when I tried to bend it back it snapped off.
