i don't want to send it out i would like to learn to do it myself other wise you might as well buy one off the shelf what fun is that
Things you'll need .
Press.
Tools to hold the trunnion straight .
Some thing to press on the muzzle .
And some thing to press on the chamber to get it back out , if you do it with the trunnion not riveted in incase you go to far . Of the trunnion is riveted incase you go to far .
Go/no go Gauges .
A good drill press and vise mounted to it . A xy vise helps but not fully needed. Mill is quicker .
Some scrap pipe and washer .
Drills and reamers . Few steel punches.
I've mainly populated after the trunnion is riveted . Which makes things easier in some ways .
After you get head space set. I use a end mill to put a flat on the barrel pin area to help keep the bit from walking .
I'll use a pin a hair smaller then the barrel pin . To center the hole in the drill press. I just put the pin in the chuck and keep moving the vice till it's in the right spot and lock it down .
I cut a flat on the barrel with a end mill. Then use a center drill and got down till the center drill starts cutting on the wide angle .
Drill under size . Ream. Then press pin .
Depending on fit . I use one inch strip of sand paper to remove material if the parts are too tight .
I use a washer on top of the part and a pipe like a slide hammer . Or press on the pipe with the press to slide the part around the barrel .
Rsb is easy to line up cause they fit in the ears of the trunnion , repeat pin drill steps .
If the gas port hole is pre drilled . I use compressed air to check hole isn't blocked .
If no hole I use the gas tube to figure out placement . 90 deg blocks you'll hand to mark and slide back to drill . Angle blocks akm style use use the gas block as a guide .
I use a digital protractor to keep things from being canted etc.
If you populate be for riveting . Cut a side of the pipe off that's longer then the barrel . Press on the trunnion with some thing on the chamber face and the barrel will pop out .
