View Full Version : MG47ES Belt feed

any plans of doing a comprehensive tutorial like gunsguntsandgod has for standard ak47 builds? it would help some of us builders who learn better by pictures and words :-)

I put my regular MG47 build on hold as the easy build physically looks more like what I want the finished product to look like. I am drooling over the images on the first page. I too started my build with an RPK kit (heavy barrel) and just picked up another kit. I think I will scrap my weld/mill build and do this one once the details are up. PLEASE provide more insight soon, specifically the FCG and bolt carrier mods...
Waiting with zest.

A-HA!!! Thanks, SharpsShooter!
Light bulb just clicked on in my head!!! :)
You've not only pointed out a critical flaw in my design idea, but you've also sparked the imagination for a possible solution! WOO HOO!!!

Here is a few more pictures of the ES on a 1919 m2 tripod I made. Also is a picture of the FCG tray that slides into receiver between the corner angles and is held in place by a couple of 1/4 pins. If the BC rails look like shelf brackets it's because they are made from shelf brackets. Normally I would bend them up with a pan brake but not everybody has one even thou you can get a small one from HF for less than $30 I believe.

WOOOOO HOOOOOO! I SEE PICS!
<premature post before reading>
ETA: Where did U get that Buttstock!?!? I've been looking for a while now for a decent FN style stock like that!!!
Also, that's a SWEEEEEEEET rear sight aperture/ladder setup!!! What gun is that from???
Cool pics of the FCG Tray! That's a pretty ingenious design format. I don't plan on making spade grips for mine, so I might do my FCG similar to your first MG-47 style (on the fence about that).
What I'm ***REALLY*** excited to see pics of is... Your BOLT CARRIER GROUP & RECOIL SPRING SETUP! That looks like a REALLY COOL, and REALLY Complicated bolt carrier setup!!!
How does that all fit together??? I'm eagerly awaiting your great tutorial!!!! I hope it's heavily loaded with pics!!!
05-06-2008, 06:14 PM
It sure looks natural on that tripod. I have just got to get mine started.
(Yeap, I'm the kind of guy who puts things off.)
05-06-2008, 06:33 PM
Butt stock is made by Tapco for a FAL, SAW249 style. Rear ladder sight is from a SMLE jungle carbine from Gun Parts Corp. (Numrich).

dude that is the shizzzzzit!!!!!!!

What he said!

Your latest creation looks pretty damn good! I'm soon to be obtaining a "different" TC and FT system to use for my build, that will be based on a Yugo M70 front end, telescoping dual recoil springs w/adjustable location feed lever actuating pin [a bearing to reduce friction], non recipricating charging handle, and like you, the FCG will be within the receiver in a drop-in module. I'll be TIG'n where I can and screw'n everywhere else, though I haven't quite decided if I'm going with square tubing, sheet metal, or a combination of both. We'll see when my parts arrive and I give it all some more thought.
I'd like to thank you and cntrailrider for sharing your unique abilities and ideas, which, for the past few months, have given me much to think about and ponder. I think smoke came out of my ear last week, LOL.
Cheers, please keep up the good work, and please post more pics when you can.

I'm dying to find out some more info & pics!
What's the width of the receiver? Length??? (It looks more compact than the original)
How did you do the bolt carrier mods & feed lever pin, & recoil springs???
The more I look at this one, the more ingenious ideas I see incorporated in this design!
You, Sir, have won the title of 'Homebuilder of the Year' for two years running now in my mind! SWEEEEEEEEET gun!!!
EDITED TO ADD:
Also, Does the Bolt Carrier modifications require you to use BOTH 'rails' created by using the shelving steel, or is the 2nd 'rail' part basically functionless?
05-15-2008, 04:03 PM
Are you still using a MG42 grip stick?? The PG on the photos looks different.
05-15-2008, 04:17 PM
The lower rail of the "U" shaped shelving steel has no real function but it helps hold the internal FCG tray down in place until the cross pins are inserted.
05-15-2008, 04:26 PM
The MG47 gripstick is scratch built to look like a MG42 gripstick and houses a complete FAL FCG. The gripstick on the MG47ES is a simple tube that only houses a trigger bar and the grip its self is SAW style AK47. The main FCG is internal just like in a AK47.

Where's the tut? :D
Had to ask, I'm sure your busy.
05-16-2008, 10:12 AM
Tuts are hard to produce when you work 10 hours a day, however, I have got the drawings about 3/4 done and about 3 dozen pictures I am sorting thru.
05-16-2008, 01:29 PM
Not trying to give you a hard time, I know the feeling of 10 hour days, it was a sad way of asking "how is it coming along".
Thanks for the update.
05-19-2008, 07:13 PM
Thanks for the info on the grip stick! For now it sounds like all I need to purchase is the MG1 or MG3 Top cover and feed tray, correct? (I already have the M70 front end and the belts) Is there any advantage to the MG3? I see it is more expensive.
05-19-2008, 11:35 PM
MG-3 is actually a little more difficult to get cycling smoothly. The springs are newer, more stiff, and it also has a lower 'pawl' lever on the feed tray that is to keep cartridges/belts from sliding back out of the feed tray (which is a little on the 'strong' side in that his has a fair bit of resistance when pushing it down)...
SO, it'd likely be easier to get a MG-1 assembly to operate more smoothly. I chose the MG-3 for two reasons...
1. I hope to reduce the amount of pressure/resistance and 'binding' on the lower feed pawl in the feed tray, as I find it does a VERY GOOD job of holding belts in place (would be good for feed tray testing).
2. Robert RTG Parts was out of stock on MG-1 topcovers and feed trays, and I didn't want to have to wait for him to get more in stock, or miss out on this kind of build.

Progress on the drawings of the ES receiver, FCG, gripstick, gas tube, gas piston, BC modification and BC extension are coming along. I hope to have something to publish by next week. An assembly drawing and a spad grip drawing to follow.
05-24-2008, 01:20 AM
amazing work. take your time on the tut as every detail helps us builders who need to have our hands guided like a preschooler:nanabang:
in all honesty, this is by far the coolest build i have seen. I check this thread daily for updates :rockin:

So it looks like you pushed all the parts of the barrel including the handguard retainer and the rear sight base on the RPK barrel, then reinstalled the gas block in the 'normal' position and the front sight base inverted 180 degrees?
06-02-2008, 09:56 AM
Every thing on the barrel is as it comes from the factory including the front trunnion (except the front sight) and is installed onto the receiver upside down. (trunnion, barrel, gas block, piston, gas tube, rear sight, upper and lower hand guards and retainer are all inverted). The front sight is install pointing up when everything else is pointing down. Rear sight is pointing down and is removed. A new rear sight arrangement is installed on the top cover or off of the back of the receiver. MG47 uses a K98 rear sight on the top cover and the ES version uses a SLME jungle carbine rear sight mounted on the rear receiver bridge.
06-03-2008, 12:34 AM
Cool, clever that you can keep everything and just flip or press of the front sight.
So what is the approximate length of pull from the trigger to buttstock? Looks to be a good 15-16" Considered using an MG42 type buttstock?
06-03-2008, 09:53 AM
Some have used MG-42 style stocks, and the Length of Pull depends upon several important contributing factors.
1.) Receiver Length - which somewhat depends upon...
2.) Bolt Carrier Extension Length - which somewhat depends upon...
3.) Fire Control Group Location & Modifications - which somewhat depends upon...
Really, the Length of Pull is going to vary depending upon how you build other areas of this weapon as nearly everything is interrelated to one another...
SharpsShooter, Quick Question... My Trunion is 1.450" wide, and I can't get my bolt carrier rails cut down thin enough for it to fit into the receiver on the rail (like an AK build)...
Do you think I should just cut the rails short, and align the trunion as best I can within the receiver (without being on the rails), measure to ensure it's perfectly straight, and then lock it into place? Or do you think I should create some extremely thin sheet metal shims with a slightly bent 'rail' to further help align the trunion? I'm not sure I need to have it on rails when bolting it to the receiver, but what did you do?
This RPK-47 kit is REALLY messy and I've got to take more time cleaning the cosmoline off it, but it's in BEAUTIFUL shape! It's not a bulged trunion, but this sucker is WIDE! Wider than my other AK trunions are...
