Usually, it's only a little bump in the metal that won't stay in place. I believe the main reason for the high cost of excellent prebans is because they are practically essential equipment for a Mini. To have a chance of hitting the target with the factory barrel, you need to fire 30 bullets. There are very few people in the world who can do this and remain standing. Mini-14 magazines are also unique in design, which makes them more expensive to manufacture. A standard magazine will not work in a Mini. It has rails on the bottom that match the location of the springs inside the gun. The only way to feed multiple rounds from one stack into the chamber is by using a double-stack or drum magazine. These magazines look like large tubes that hold several dozen cartridges and are usually attached to the back of the gun near the handle. They are bulky and difficult to carry around, but since most shooters only need ten or fifteen rounds at most, they aren't too inconvenient. The first thing you should know about mini-14 magazines is that they are expensive because they are made to order. When manufacturing a magazine, first we need to determine how many layers of steel there are in its body. For example, a six-layer magazine would be stronger than a four-layer one. We also need to make sure that the edges of the holes don't touch when the magazine is full.
