all of the above, it is well known. Well I guess I should have waited before drilling my nozzle to 13mm then lol. My mg is very smooth though so I think I will still be ok. still want to shoot the 200 rounds I have left though and keep an eye on a weld that Im not too confident in so if it survives...

Here is a picture of how the charging handle sits in the cuts;

So was drawing the charging handle slot. And was messing with my machined ratchet plate from global machine and i dawned on me is the charging handle supposed to glide in the cut in the ratchet plate? It seems like it should, also how much room for for varience is there for measurements on the cuto...

In fact just use newest stuff

What about it is bad? Is it hot, inconsistent primers or dimensions?

To answer your question i dont have any prior machinists skills just kinda floating through this, hence why im gathering all the information i can, i have a gunsmith local im good friends with but he made it clear he wants nothing to do with this build Building these guns are pretty far past the ab...

Here you go.

I don't know if you have seen these or not but I would print out a set. I don't remember if the rail measurements are in there anywhere but if not just call BRP and speak to Brian, he is extremely helpful and full of information. Whatever you do don't rush anything, look everything over really well ...

I have a few bugs and deburing to do before putting a finish on it. Built with a BRP receiver kit and made my own steel grip. Probably going to parkerize it but tempted to hot blue instead.

Personally I have inconsistent primer strikes...

I don't doubt that the spring is wrong, if anything my receiver would be. Im not an engineer either but I think I can figure this out soon if nobody else can. Thanks for all your help!

I made a nice jig for welding mine up. I used a block of steel that I machined to fit snug in the rails. Both ends of the block were bored to except a 1in rod on one end and the buffer spring in the other. The 1in rod extended to the front bushing and had a sleeve that fit snug between the rod and b...

Just checked my recoil spring. When the bolt is in the full rearward position there is 1.5 times the thickness of the spring wire left between the coils. Im not sure if this is correct but if it is supposed to be tighter I can make a spacer to go behind the spring. Again I am using a recoil spring f...

I used the brp stamped sections and built it myself. Made my own trigger group because the brp one placed the hammer too high so i lowered the mount holes .07in. And I used the brp kit to make my own bolt carrier semi-auto. Just checked my ejector and the center is flush with the bolt face when in b...

I used the new semi auto spring from brp. I also built it to the drawings that brp has but mine came out 1/8in. shorter. I was thinking about making a new ejector that is just short enough to not interfere with the casing until it ejects it and then trimming it down until Im happy with the ejection....

It is semi-auto. If the flash hider is not meant to be unscrewed then why dose it have notches for that arm that comes from the front site to hold it inplace all around it? And as far as I know the booster has no threads to loosen or tighten. I did drill my booster to 12mm from 11.5mm but it made no...

I recently finished building my first mg42 and was told to only run Romanian surplus or commercial ammo through it. It seems that there are two variants of the Romanian surplus and the kind I have is giving me issues. Powder and dimensions seem good but I am getting very inconsistent primer strikes....
