K'nex gun question: When firing a k'nex gun, have you ever experienced kick?

History:
A few months ago, I built and modified I_am_canadian's stryker pistol(Is that how you spell it?).After piling on the rubber bands, I experienced what was more than a slight kick.Today, I had modified my ratchet-system design for a rifle (Built 100% from scratch!{Except for the ratchet itself.})in order for it to not waste power, and upon firing, I felt it.The kick I experienced was not as great as that from the strryker pistol, but it was fairly noticable.
______________________________________________________________________________
Connections or possible explanations:

-Both instances occured after a power-related modification
-The communists did it!
-Both were ratchet systems
-COMMUNISM!
-They had more rubber-bands than they were ment to hold
-HIPPIES (Them, too.)
-Both were very powerful

As you can see, between the hippies, the communism, and the scientific explanations.
There are many possible answers (A few of which are serious in nature.), and one or many could be legitimate.

So the question stands: Have you ever experienced kick while firing a k'nex gun?

According to physics, there is a very slight amount of recoil. Normally you don't even notice it. The ammo and air being pushed out of the way by pins or sling bands are hardly anything to actually resist the gun. In a regular firearm the gases escape through the barrel as well as push back the firing pin assembly which causes recoil. In a K'nex gun though the force of the firing pin or sling bands stop on the gun which should mean the majority of kick would be downward.

To put it simply: it depends. To explain it: most K'nex firearms will not display noticeable kick as the round is propelled by a firing pin. To provide the force to move the round it must provide a force greater than said round's inertia. Due to the fact that the force is greater most Pin-Operated K'nex firearms will kick forwards not backwards, and usually there is a slight downward kick as well depending on where the firing pin enters the firearm, its mass, and the force behind it. However Slingshot-Operated firearms will display a kick directly proportional to the mass of the round and the force with which it is fired. The reason that Slingshot-operated firearms will exhibit a kick while Pin-Operated firearms will not (noticeably) is because while the Pin-Operated firearms require an object of comparable mass and energy to move the round the Slingshot-Operated weapons use an object whose mass is (comparatively) very low  and whose energy is (also comparatively) very high. The high mass (and therefore inertia) of the round coupled with the high energy of the band(s) results in the kick you feel when firing Slingshot-Operated firearms. A kick can also be exhibited if a very heavy load (something in the range of a grey/black rod with a blue 3D "sphere" placed on the end and filled with yellow rods) is used with a powerful, lightweight (the lighter the firearm the less its inertia and the easier it is to feel the kick) firearm such as Killerk's first pistol.
My pistols always twitch some when they fire because of the firing pin hitting the back of the gun, so it seems pretty normal to me.
In my case, I built a modified Javelin off 'ibles. I haven't gotten a chance to fire it yet but it seems as if it'll have a crazy large amount of recoil-the ammo is half the size of my forearm.
Well, Ive only experianced recoil from 2 knex guns. 1: Viccies HAWC with 20 elastic bands on and 2: My full auto v5 with the huge block o' orange connectors.
