MG42/M53 School Me, Need Semi reciever

Ok,, thinking of pulling the trigger on a 53 kit(before their all gone) to build into a semi with some dirty bird dressing to be as period correct as possible. Talked to ATF and looks like I need to find a whole semi receiver or some manufacturer that will stamp their number into a re-weld, or finish up an 80% for me.
RTG is about 2 hours from me up here in North East Wyoming, where we enjoy some freedoms that the rest of the lower 48 except maybe TX don't have.
Been over on Weapons guild for a couple years and haven't been on here much since finishing the 1919 back in 2012. But the riff Im getting on the WG is to build what ever you want in your own garage, Problem there is I need to be able to get rid of this thing someday down the road should the need arise ( I like tangible assets but assets that can move)
Bolt mods and other semi work is easy as I have a couple machinists at my finger tips, and Im setting up my own shop for my own purposes.

Don't reinvent the wheel. Buy BRPs proprietary semi bolt and grip system. It is excellent with replaceable parts. If you are going to weld together the receiver, stay away from most repro receiver sections, or if you want to buy any of them, do serious enquire from any builders who have used them. Many are out of spec enough to require much fussing and fitting. Muzzle bushing repros are good, in my opinion, and the shroud muzzle sections are close enough to not require extra fitting. I highly recommend finding a Yugo or WWII kit with all receiver parts. A number of the most time consuming and difficult additions to the standard receiver have been done on a vintage receiver, but not on repro receivers.
Good luck,.......

Most builders go with stamped halves from UZIMAN on weapons Guild. He had a sale on them last weekend. This is a rather involved job to build. I really doubt there's a builder doing this for profit, too much labor. But you never know.

I think you can still get a complete receiver from BRP parts.

This is one of my favorite to shoot weapons

Thank thus far,. Have heard mixed results on the brp receiver sections. Talked to Philadelphia ordinance today about their 80% receiver. But it still leaves me needing a manufacturer to press some digits in this thing,. The 1919 was easy as Halo provided a great plate.
Kit I'm looking at is a 53 but likely a torch cut. Gonna move slow, as I have too many non gun projects going right now, but want to get the parts for later. Still kicking myself for not getting a second 1919 kit back when they were $450. Or passing up a partial M2/M3 kit for $2700 while trying to pay off the wife's student loans.

Btw,. Yes I am a member on weapons guild,. Not many posts but countless hours researching. In the words of Mark Twain-. Better to appear a fool than open ones mouth and remove all doubt. Thus I remain in the shadows. Steel Soldiers and Cummins Forum are my real expertise. Wife let's me pic up a gun project every couple years

Karl T is right....

if you cant do it "yourself"?

the BRP receiver is a great way to go. Tony was running a special discount on these thru BRP... think that sale is over though...

UZIMAN is another great way to get you a receiver section....

42/53's are not that hard to build.... especially not now days with all the goodies available. all you really have to do is line it all up, space it properly & then weld it carefully.

BRP grip stick & doing the bolt is easy.

you mentioned selling it later. you can sell any homebuild later on. that is not an issue.

its if you start doing homebuilds with the INTENT to sell them.


these are still one of the baddest beltfeds out there & every body should have one!

Its been a long time since I built mine, but heres my .02

1) Find an original 3 cut receiver. Pay extra for one that DOES NOT have the booster threads cut. The advantages are you will have all your dirty birds and you wont have to mess with all the issues that these 'repair sections' have. (such as pressing in the booster thread collar). I don't know how much progress theres been in the 10+ years since I built mine, but back then, aftermarket replacement receivers, repair sections and such were pretty rough. If you can find (and afford) an original 3 cut, go with it.

2) The bolt camming piece has to be drilled out for the firing pin to pass through. Its made of the hardest substance known to man. If you are doing this yourself, be warned and buy a few very expensive bits.

Other than that, its a pretty straight forward build. +100 for the cool factor.

If you want to chat about building MG42s, give me a call as I have built dozens, mostly post-samples, but quite a few semi-auto, repaired many bad semi-auto builds and am finishing up 12 semis of a mixed lot of repair of bad builds and new builds, and own four registered NFA examples. 802-226-7204

to follow up on this:

UZIMAN is running a special right now... it ends TONITE.. but if you check it out over at WG & call him he will probably honor the price.

he is a very good dude.

Thanks guys.
Bmg-. I will likely give you a call soon.
Things progressed rapidly today, called uziman and ended up getting one of his repair sections with cut out and ratchets. Next I called on the kit to check availability and was told they only had 8 left,. Uh ohh,. Well Apex only has 7 now.
RTG is about 2hrs away so I plan on seeing what I have when the kit gets here and swapping out some of the 53 parts for the dirty birds and or some old numbers or such. Which still leaves the Delia of getting a manufacturer to stamp/log it but that's a few years off by the time I get it running properly. Gotta find a good tig welder,. My Sean MIG is good but tig would be better.

wow dude! you jumped on that fast! congrats!

told ya UZIMAN was top notch! APex & BRP are also very good to work with. you are on FIRE!!

now on that seanMIG... LOL you made me chuckle there. MIG is great for this.

IF you are a good welder with a TIG & dont warp things? sure go TIG! but im a Gobstopper/puddlejumper as a welder.... so its MIG for me.

glad we could help you spend your money!

Autocorrect is a stinker, it changed Esab MIG welder to sean, and Delima to delia

I've built 7 so far in semi, all of which work great for a semi conversion.

My favorite combo is the Centerfire M53 kits (seem to have the longest cut shrouds in the rear, most have intact front rail hols and recup hole (IMO a couple of inches extra to the rear of the camming piece makes these builds much easier, combine this with the mentioned Uziman shells, use the BRP grip stick and bolt kits, for another easy shortcut use the RTG MG3 rear stub (makes the whole buffer tab hassle a breeze), also the RTG MG3 front bushing makes it super easy....that and some RTG MG3 undrilled rails...I tap these and use screws, at least till after testing (can rivet later).

Lots of time measuring, squaring, some welding and about 50 dremel cut-off disks later and you are there...lol. Keep it straight and watch your lengths. All the info is on the WG site BTW. I'm active on that forum as Tom5390. If you need anything feel free to give me a shout.

Argh. I forgot my WG pwd and the site said they'd send an email to reset it, but no email, not in junk either.

So I googled Mr. Uzi and MG42 and find some info, but not good info and no pics! Can anyone tell me what you get from Mr. Uzi, what work needs to be completed, and how much the sale price was?

Thanks!
