I'm a pretty pleased person if you ask me right now but at mid day earlier today it was a different story I have a Vepr AK and in order for it to load standard AK Mags it needs a bullet guide, so I ordered the part kit. Kit included a drill bit, tap, screw and bullet guide. Screw up #1 I lined up the guide and took a punch and made a mark in the circle close to the barrel. I drilled it and then I tapped it, come to find out I drilled too close to the barrel and it didn't line up right with the guide so my immediate thought was I just effed up a $1k AK. Screw up#2 so I decided to retry far enough from the 1St hole so the 2 wouldn't merge and more accurately so it would line up right. Today was a hot day and I was dripping sweat. My glasses were covered in sweat and fog so I lifted them up on top of my head so I could see. Just as I thought I was making good ground my tap broke. It snapped and because my glasses were on my head chunks flew into my eye, but luckily my reflexes shielded my eyes. I was upset I broke the tap and had to go buy another. Screw up #3 because I had to move the bullet guide over from the center to the side my bullets would not load and had no idea why. I looked closer and realize the casings were getting caught on the guide. So I figured I wasted a good part of the day on something that wouldn't work. But after thinking on it after a smoke I relized it's because the guide is square it creates an edge to get caught on. So I eliminated that. I filled the edges and made it more of a ramp. I tested it and it worked. I then sanded it down with 400 grit and I polished it to ensure it would remain smooth and eliminate the risk of rust from exposed metal. I then installed it and made sure to loctite it. I then did a trial run of 5 rounds. It was the smoothest action my AK has seen. Every one of my errors could have been avoided if I had taken my time and had been more cautious. I took a 10 min project and made it last 2 hours but this was the first time I have done anything like this. I think next time I'll take my time and check every aspect of what I'm doing.
