This one has a bit of a story behind it. I've started working on a roller delayed blowback mechanism in phun, then algodoo became free so I could continue my work in it. That mechanism proved to be useless, it didn't make any difference, but it also didn't affect reliability of the weapon in any way, so I just left it there.
Later on I've started using this gun as a framework for testing different trigger groups so I didn't event plan to finish it.
Eventually one of those trigger group designs proved to be very stable and it worked almost every time. Therefore I decided to finish this piece and upload it here. Have fun.
CONTROLS:
[enter] - pull the trigger
[left/right arrow keys] - change fire mode
[down arrow key] - operate magazine release
FEATURES:
- Roller delayed blowback mechanism (doesn't make any difference)
- All 3 fire modes (single shots, fully automatic, and 3 round burst)
- Safety
Bolt doesn't lock back after the last shot, but you can manually lock it back for reloading. (weapon fires from closed bolt)
Magazines hold 15 rounds and can be a bit tricky to load without some of those rounds falling out.
Weapon works quite well most of the time, with exception of some failures to eject. Also I've encountered a weird bug a few times with cloned magazines - weapons works fine, and all of the sudden most of the moving parts disappear. I wasn't able to determine what causes it.
Thanks to DualDesertEagle for the video.
