Mad Bull Airsoft have sent in details about their GemTech T5 system:
This is Gemtech’s new product lines, called T5. It was listed as Gemtech’s latest product but is not online now.
Anyway, we are producing the replica now and we have a new idea to solve rail handguard swinging problem.
The real gun is using "gas pipe" to index the rail system and upper receiver.
Toy guns don’t have the "gas pipe" and the rail handguard may swing and can’t index.
In order to improve the swinging problem, you can either
(1) Use "MadBull/MAX Tactical RAS FIX" scope mount
ideal. [See below](2) Our new idea:
This new device is special designed for Airsoft guns (without gas pipe.)
Mr. J.C., Art Center/ USA, is the designer for this device (The red color one).
Anyway, many new items coming. Let’s wait and see! MadBull
