Pauld Posted June 3, 2021 Share Posted June 3, 2021 Hi, I'm trying to do some upgrades on CZ Bren 805 but can't find many options. Want to do the hop up to start with and potentially the barrell. Anyone done in on a Bren or know what parts would fit? Im struggling to find any guidance. Thanks. Link to comment Share on other sites More sharing options...
strykerles Posted June 4, 2021 Share Posted June 4, 2021 The gun has a proprietary hop afaik so might only beable to do the bucking and nub the gearbox is a fairly standard V3 although the ambi selector makes the gearbox a bitch to get in and out also the motor wires were soldered to the motor so watch for that I gutted mine as it was shite out the box I fitted :- Gate Titan 16:1 gears full steel rack piston airsoftpro o-ring nozzle SHS high torque motor afterwards it was turning out 380fps so I changed the spring and it now clocks in at 335, very snappy on a 7.4 or 11.1 Link to comment Share on other sites More sharing options...
