Manual
After about 3/16 (5 mm) of bolt travel
(or .0013 seconds) the bullet exits the muzzle.
The pressure in the barrel has now dropped to
a low level.
On it's way backwards, the bolt cams down the
trigger bar, ejects the empty case and cocks
the hammer . The bolt is gradually slowed down
by the recoil spring until stopped by the buffer.
The recoil spring drives the bolt forward, the top
cartridge in the magazine is picked up by the
breechface and pushed into the barrel.
Close to battery the disconnector engages a cut
in the bolt and allowes the trigger bar to engage the
sear again.
When the trigger is released the trigger bar moves
backwards and behind the sear. The SUB rifle is
then ready for the next shot.
