Knex Spas 12

Introduction: Knex Spas 12

About: This profile is purely to express my interests in building (not only Knex but Lego too). Check out some of my reviews, projects or instructables which I hope you may either build or get inspiration from! Hap...

Hi!
Well after looking a airsoft shotguns with my friend I decided to have a look round instructables for a nice looking pump-action shotgun (not an actual shotgun but a more lookalike gun) and I was pretty disappointed :(. So I decided to have a go myself!

Well this is something which I hope is a big step forward for pump action mechanisms. I was really trying to make this gun more realistic than anything so for that reason I opted for a SEAR trigger mech. The firing pin is pushed back by the pump and then held in place by the trigger mech whilst the pump is moved back forwards to it's original position. The firing ram again returns to the pump and the whole thing is repeated. Unfortunately because of the complex pump mechanism there was no space to put a horizontal magazine behind the pump but it could be possible!

PROS:
-realistic looks
-SEAR mech hardly ever jams
-Low cap 4 round mag
-Real pump-action!
-True trigger!
-Sights (not shown)
-Sturdy

CONS:
-Terrible range (15ft max but remember this is largely a concept design)
-Elastics to hold the ram down 
-Mag at the front because that was where the only space was :(

Well to round off with some news, I think that I am going to try and remain making more realistic guns rather than guns that look crap and my next ible is a P90 so look out for that!

thanks as always!

    It looks more like a stakeout, cuz the Back has to be higher than the rest of the gun

    in the comments is someone who made the gun and modded into an spas. You can build the original one first, than change it until it looks a bit like in the comment

    Ya I know it could be better but I was getting a little bored because I had spent a while trying to get the mech working...

    Very cool, the handle could be a little better, but still, great gun!

    I agree but I was getting a little bored because I spent a long time trying to get the pump action right.
