Rap 4 has just released a new video update on the D-mags, I have to assume with their short video release the other day and a lot of skepticism on the whole design they released a more detailed version to show how everything works.
These stacked mags are basically just 2 tpx mags side by side, they will come in a 14rd, 20rd and even a 30rd configuration.
As you can see in this video this new marker set to be released some time this year it will use a very similar design of a double stacked mag.
I don't really see any huge problems with these mags other that the fact that you have to turn the mag half way through shooting. Its not really that big a deal and it will only take about 4 seconds or so to actually turn the mag around. It might take a little for some people to get used to but all in all I do think that this design is going to be a winner for first strike users.
Now the real thing that got my attention was the curved D-Mag, in the video they show you a mag that will fire first strikes and that they CAN IN FACT TURN CORNERS, they just have to be loaded differently.
Also both designs have eliminated the loading head and the mag release, if you play mag fed you know how much of a pain they can be sometimes. There was no working model, price, or release date of these curved first strike mags so I would have to assume they are still in testing but I cant wait to see how they preform.
I really like the way that these things look and believe that they are a step in the right direction for mag-fed paintball, if done properly they will redeem rap4 for mistakes that they have made in the past and will bring back unhappy customers.
