Algodoo

Mauser 98K.
It has realistic mechanism with cocking on-open firing pin, and 5 round stripper clips.

To shoot:
1. open the bolt (move bolt handle up and back)
2. take the bullet or stripper clip.
3. put the bullet inside the integral mag (point it into the right direction!), or load the stripper clip into the cut in receiver. Do NOT try to pull the whole stripper clip in! Only bullets go in.
4. close the bolt.
5. pull the trigger.
6. repeat those 5 steps untill you'll run out of ammo.

[EDIT]: Fixed most of the ejection problems (spent cases still dont fly out far enough, but its much better now), and added missing rear bolt cover (part of the receiver)
Make sure you have the latest version!

IMPORTANT: Weapon has some problems with ejecting spent cases, so watch out.
Operate the bolt gently because it likes to break.
Have phun!
