hop up fixe et metallique:
Clarence sent us a few detailed photos and some info on his latest custom project. We're talking a new HopUp system for the Marui Hi-Capa, Glock & SIG series GBB pistols. It's a completely new design where most parts are metal, the only rubber you'll find inside is the O-Ring. The unit is a non adjustable, fixed HopUp, which according to Clarence, works best with Excel 0.23 and 0.25, in conjunction with PDI 6,01 mm Palsonite inner barrel. Such a setup should give a very consistent grouping and a very consistent FPS output of 345 FPS measured with the 0.20g BB. This will be a low volume production series, limited edition. As usual, more right bellow:
This is my coming out new product, I design a new Hop up system for Marui Hi-capa, 1911, Glock and P226, This hop up is made by CNC 7075 aircrift Aluminum, I am using special o-ring to lock the BB inside the chamber, Japan PDI making the 6.01 PALSONITE inner barrel with a special Cut, to fit my Fix hop up rubber, this rubber is special order from Japan O-ring making. You will never have the Problem with loss out BB from standrard Hop up Rubber. The Grouping and FPS you with be 40%up ! The best Group is using Excel 0.23 and Excel 0.25BB. This new hop up barrel set coming out with 5 inch ,6 inch, and 7 inch three size. Each size is only limited in 50pc.

J'ai hâte de voir ça de plus près, tout en alu CNC, ça respire la haute couture
