airsoft spring shotgun bullpup kit

thingiverse

The kit is built around a cm.355m spring shotgun from Cyma. I am still experimenting and testing the different parts. I try to make as many updates as possible in the meantime. A lot of filing and modifying has been done. ---------------------------------------------- 15/03/2020 at 10:30 A front grip mount was added without a grip so you can add your own grip or picatinny rail. 16/03/2020 at 8:25 Files and photos about the replacement trigger and mag release mount/trigger mount were added. 19/03/2020 at 16:18 The trigger mount v4 was added because v3 looks a bit blocky on its sides. V4 has also been reinforced a tiny bit in the back. Part settings are being updated a little bit. Prototyping and fitting is almost done! Expect new information soon! 21/03/2020 at 10:12 Prototyping is almost finished, and it might be redesigned with the new trigger. A photo was added. 26/03/2020 at 9:14 The rest of the parts were added, but they are v1 and not that good yet. Updates to these parts will be added soon! 2/04/2020 at 12:38 M4 (Mark 4) parts were added: these are the best parts so far. 2/06/2020 at 13:20 The project is being rethought, and new parts are being worked on (coming in the future). 3/06/2020 at 11:15 and 17:55 M3 parts were added (front grip with picatinny rail, new trigger Mark 3, and a new grip with AEG M4 grip attachment). The screws needed are four times m3x8 with .5 pitch, friction fit. At 17:55 A grippart M5 was added for actual real firearm grips. They need an m6x27mm bolt and an m6 nut.
