CNC-machined stainless steel loading channel, suitable for our Neptun HopUp Unit
With this loading channel, the remaining BBs are held back during reloading and do not fall out.
Three O-rings are included in the scope of delivery:
7.5x1mm - To be installed at the top (see last store picture)
5x1mm - for the lower groove
5.5x1mm - for the lower groove (optional)
Depending on the O-ring used, the BBs are held less or more firmly in the channel.
Please note the following important information:
When developing the NEPTUN, we decided against such a system in order to avoid feeding problems. In response to several customer requests, we now offer this optional loading channel. However, the correct function is only possible with a correspondingly strong spring in the magazine. For example, if you use a magazine with a weak spring and heavy BBs at the same time, the spring will not be able to push the BBs through the O-ring. This results in feeding problems. Alternatively, the enclosed 5.5x1mm O-ring can be used in this case, with which the magazine spring requires less force. The BBs inside are held correspondingly less tightly. Correct feeding is therefore even more dependent on the magazine used and the bullet weight.
If you already have problems with your magazine, we advise against using this loading channel.
This loading channel (like the original) is also adjustable in length. If you screw it in too far during installation, the magazine will not release the BBs.
For most weapons, it is sufficient to screw it in fully and then turn it out one turn. If you have to push the magazine forward in your gun to achieve feeding, the channel must be turned out further until the correct setting for your gun and magazine is found.
