First Build Virgin M92
12/29/2011 8:25:09 PM
This will be my first build..i know i know i coulda found an easier kit for my first build but this is what i got so Im gonna do it....I been researching non stop for a month now and I'm pretty darn confident i can do this...Im going to bend a flat not use a nodak. I don't have a flat to bend yet but i think i can get my barrel ready while the flat is in the mail...
Im going to have a lot of questions and hopefully you guys can help me out.
FISRT off I measured all the journals on the barrel and the parts that press onto the barrel all my tolerances are good to go...heres a pic below
My next step is to do the barrel face cut, I plan on doing this with a dremel and a file since i don't have a mill or access to a mill....here is where i have my first question.
1. How deep do I need to cut into the face of the barrel?
Im thinking ALMOST flush with the bottom of the chamfer (see pic), leaving just a little of the chamfer and then using very fine sand paper i will relieve the bottom of the chamfer to facilitate a positive feed angle. ANY advise or tips here will help.
2. The barrel face cuts I've seen on M92s look like its ABOUT 1/4th of the barrel (see pic). Then orientated in the 11 o clock to 3-4 o clock position when pressed into the trunnion
Is that a close enough measurement or do I have to be more precise here?
^^I got this pic from another forum^^
Next step I will Headspace the barrel, drill the barrel retaining pin hole, drill the rivet holes in the front trunnion.
Thanks for any help

I am in the process of building a virgin M92 as well. I am a little further ahead of you in that I have all of the barrel work done except for drilling the gas port. I do not have a mill so I have to make the cuts with a file by hand. I used a flat narrow file to cut the extractor cut like the picture you have. I just made the cut deep enough so that the extractor clears the barrel when the bolt hits the barrel. I did the 90 degree cut because that is what is standard on AKM patterns. The AK-74 cut would be easier since you could use a full length file and take longer cuts.
I used a chainsaw file to cut the groove for the handguard retainer. You can do a good job with a file if you take your time. If you have any questions you can email me and I can help if I can.
