No manufacturer out there (minus Tokyo Marui) has replicated the dimensions of the AKS74U's stubby bolt handle. Here's what it SHOULD look like, courtesy of Tantal's Avtomats in Action page. The AKSU in question is a Tula-made, 1983-dated AKSU in use with the Ukrainian military.  This isn't a hard bolt to replicate in airsoft, you just need some time and willingness to cut. In my case, since I'm cutting a DBoys AK bolt (which you can't replace) I was a little leery. That said, it's not hard to do. Here's what you need: -Bolt of choice -Ruler -Dremel with: +Cutting Wheel +Sanding Drum -Rat tail file* -Fine-grit sand paper -Vice First, make a mark 1/8" down the bolt handle from the tip. This is where you need to cut down. In my case, I free-handed it, but methodical work usually yields more accurate results, right? Now place the bolt in the vice, and take out the dremel wheel and cut at a slight outward angle down. A 15-degree angle works just fine. The tip of the bolt drops off, leaving the fun part - shaping and cleaning up the bolt. I used the rat tail file, a metalworking file at that, to attack the tip from the other side, again at a roughly 15-degree angle. The two angles should meet in a point at the middle. Now file THAT flat. Use the dremel sanding drum to round the edges to a good smooth surface, and then tackle it with the fine-grit sand paper to finish up the bolt so that when you refinish the bolt it doesn't look like a cheap Chinese CNC'd part. Here's what you should now have (and my apologies for the slight out-of-focusness):  Paint to suit. I use Rustoleum gloss black, as it seems to match the Russian finish pretty well. *optional, but highly recommended. If you don't use this, just cut straight down and hit it with the sanding drum as described above. |
