Making a barrel or even a breach to shoot first strike is one thing. But making a mag to put the first strike in to said barrel or breach is something totally different. I would assume that Tiberius would have a good patten on the mag for the first strike. But they would want their competitors to accept the first strike, that way they make the most money in selling the mags for all the different markers (when they are ready) and the first strikes them self. Rap 4 is trying to come out with the "Dmag" it's not here yet? Think it has something to do with being able to take the Tiberius first strike? It's the same as after market parts for Tippmann. They want the companies to produce the parts that way they sell more Tippmanns. But try and make the same main body parts. I am sure Tippmann has a huge patten on them.
Just my 2 cents worth.
