I am very satisfied with WE M14 magazines. I have even dropped it a few times and it continued to perform admirably. I have had one leak and fixed it by simply tightening the two main screws as mentioned above. Overall, I have found the magazine to be rock-solid and very reliable. It can be located by unscrewing the two main screws on the bottom of the magazine and separating the two halves. There is one large O-ring that is located on top of the bottom half of the magazine. This process is simple and will be reviewed in the disassembly section. You can convert the 20-round magazine into a 30-round magazine by swapping out the screw. If this is the case, then you can also tighten these with a flat-head screw driver. It's possible the leaks are occurring because of either the fill or output valve. You can hold the magazine next to your ear to see if you can still hear a slight hissing sound. Most leaks occur here and they usually stop when these two screws have been securely fastened. The first thing you can do if you have a leaky magazine is to tighten the two large screws. The two larger screws keep the bottom and top half of the magazine together securely. The small smaller screw keeps the magazine attached the magazine shell. If you remove the metal plate on the bottom of the magazine, there will be two large screws and one small screw at a slight angle. The trigger is inserted into the stock by pushing down on the trigger guard until an audible click can be heard. Additionally, the trigger unit seems almost indestructible the entire device is made out of steel. This trigger unit works flawlessly and one never has to worry about the trigger unit malfunctioning like the stock trigger unit. This is an extremely expensive upgrade but is completely worth the money. The upgraded RA-tech trigger unit is $199. This is because the stock trigger is composed of two main parts that over time begin to separate away from each other and make the entire contraption useless. The main point is that the stock trigger will indeed begin to malfunction sooner or later. This number may vary as I have heard of it splitting after anywhere between 500-2000 rounds. The original trigger unit is prone to many problems after a 1000 rounds. There are two variants: the stock trigger that comes with the original M14 and the upgraded RA-tech trigger unit. It is by no means complicated once you become familiar with the system and know how to disassemble and reassemble it. The trigger unit is quite different from that of my old Ares AW338.
