K'nex - SPAS-12 Instructions

Introduction: K'nex - SPAS-12 Instructions

Hey guys, and today I bring you instructions for the SPAS-12 (Sporting Purpose Automatic Shotgun). The SPAS-12 is a duel-mode shotgun, it is able to fire in either pump-action or semi-automatic. The pump-action system would be used in riot control to fire non-lethal projectiles such as tear gas and bean bags.

Anyway let's talk about the SPAS-12, it's not my own design since I followed instructions from the Knexinnovation website which seem doesn't seem to work anymore. After building it, I went on to make several improvements and of course I have made instructions so you can have your very own SPAS-12.

Good Points

· Very Realistic

· Includes Folding Stock

· Comfortable Hand Grip

· Includes Pump-Action

· Good Iron Sights

Bad Points

· Uses Quite A Lot Of Cut Pieces (See Parts List)

· The Whole Gun Is Flimsy

· Doesn't Shoot Because It's Just A Model

Specifications For A Real SPAS-12

· Designed - 1972

· Number Built - Unknown

· Ammo - 12 Gauge

· Rate Of Fire - 4 Rounds Per Second If Using Semi-Automatic

· Powered - Pump-Action and Gas Acutated

· Magazine - 8 Rounds

. Range - Depends On Which Ammunition Is Being Used

In Call Of Duty: Zombies, the SPAS-12 is available in all Black Ops maps where it is only available from the Mystery Box for 950 points. It has a potential one shoot kill up to round 13 however the ammo count for it is very low. Speed Cola is very useful af decreasing the reload time of each shell. When it is Pack-A-Punched for 5000 points it becomes the "SPAZ-24" where you get more ammo, more damage, quicker reload time, bigger magazine and it also becomes fully automatic even though the player can still fire it semi-automatic. It has a one shoot kill up to round 20 but ammo can be a problem if using it fully automatic and the only way to get more ammo is through a Max Ammo power up.

    No the Double Barreled Shotgun has more parts than the SPAS-12

    This is one of the better SPAS 12's on here, good job! I favorited it.

    This gun looks really really nice but in my opinion, Blackshadow12's trumps all others. I really like the look of the pump on yours though.

    I can 100% agree with that since the ammo can be bought of the wall

    Wow, impressive!

    This is THE WAY to document a knex gun build.

    Yes, I've noticed how well-done they always are! You've got an excellent presentation style, and an eye for what needs to be shown and how. Always great work!
