What you need:

A sentry gun
C4
Enough money to purchase a gun afterwards

---

1. Have your partner down (if you want, you can knife him)

2. Take out your C4

3. Pull out your Sentry Gun and revive your teammate at the same time

4. Once done reviving your teammate, place your Sentry Gun down

5. Purchase a weapon

6. You now have multiple weapons!

*Note* You cannot pick up the Sentry Gun you placed down, or it will ruin the glitch. If you want to get more weapons, you have to buy another sentry gun for each extra gun.
