-Cheek rest
-True trigger
-Better than before sight
-Lots of possible additions(compatible with MBAR-2 gear)
-Semi-Auto
-Reliable
-Safety
-Side ammo storage
-Extra compartment
-Trigger guard

Cons:
-Uses a lot of pieces
-Can be complicated to load for some

To load remove the mag and place the pin in the appropriate area. Now place the ammo in the mag. Insert the mag into the ammo feed. Next push the white and blue rods in the ammo feed area out to the sides. Hook the rubber bands on the end of the barrel and the trigger spoke. Make sure the rubber bands are on both sides of the ammo. Once all the rubber bands are hooked push the blue and white rods back into the center. Remove the pin. Pull the trigger to fire (in case you didn't figure that out).
