I have a SG-43 carriage to shoot my 1919 with. I was thinking about buying an SG43 kit to put together. Does anyone have any experience with building one and the challenges that go with it, availability of parts, etc. thanks[/QUOTE
Its a very easy build and lends itself well to the homebuilder with little to no tooling.
The BBL can be tapped and plugged. Most BBLS have a drill hole in the chamber, so be prepared for ruptured cases (its almost impossible to get the chamber area perfect with the tap and plug method, but it will be functional). Its not going to be real accurate, but the only other option is a 800 dollar live bbl. (verses 1.29 for 3 allen head plugs)
The receiver is simple. I made a welding jig with 30 dollars of aluminum bar stock from Home Depot. I took the stock to a machine shop and had them mill a few thou off the side so it would fit the box. If you are serious about this project, Id consider selling it to you for cost. (PM me)
I also used the side mounted AR-15 fire control group. I suggest taking a chunk of the welding fixture material and converting it to a box to hold the FCG. Again, I had a shop mill this out with very simple dimensions. Total machine labor was less than 50 bucks.
The denial pins were simple, milling the bolt can be done with a dremel. Make SURE you remove ALL the leading edge on the bolt carrier...if you dont, (even though you've made it a semi) the extra metal will cause slam fires and a run away, full auto gun. (All these steps can be found online, I know I posted a pretty in depth tutorial on Weapons guild about 5 years ago)
Again, the BBL is the hardest part. My gun runs, but gets every 10th case split and stuck due to the small depression in the chamber where I couldnt really machine it out well.
I'am probably going to start by just buying the parts kit from APEX and the other components and hold on to them for awhile. I'am not going to rush into this build, have alot going on right now and it's a little out of my wheelhouse to just charge ahead and do it myself. Thanks for your feed back everyone and the build sounds doable. My cousin from Cal. built one and is coming out for a week this Christmas. I'm sure we'll have a good bonding experience with the build. Thanks again
thanks for the info.Make sure you get a BBL with the 3 holes drilled in it. If you get the kits with torch cut BBL...throw the BBL away. It CANNOT be reworked. Also, make sure you order the SG43 kit (and not the armored variants, as they dont come with spade grips or sights).
thanks for the info. I just talked with my cousin and he has been saying the same things as you guys. He was an under water welder and then welded heart valve seams together for a living. So I'm hoping we can do alot of this ourselves. thanks again and sounds like a great build. I'll keep you guys informed when I start to buy some of these parts.Just be careful of who you send the barrel to on the plug/reweld. One was sent to Georgia Weaponry and it came back with JB weld in it to help plug the holes. Heard Wildhorse does good work though.
My brother was a Hull Tech in the Navy is that what your brother did?thanks for the info. I just talked with my cousin and he has been saying the same things as you guys.

He worked for individual companies, several through his life, he ended up working with heart values, and some of his work had been in confined areas and now unfortunately has some health problems associated with it.My brother was a Hull Tech in the Navy is that what your brother did?
