A block trigger muzzle-loading K'nex pistol. These are my favorite K'nex guns, both because of ease of use and high power. It even has a sight-ish piece on the side, although I've found it easier just to aim by pointing the gun in the general direction of the target from about chest-height.

By flipping the trigger over to the other side you can make a left-handed version of the gun. You also have to flip the blue and silver rings and the sight.

Modifications and suggestions are welcome. Just make sure to leave a comment!

Note: You need to look at all of the pictures to know exactly what I'm telling you to do. Some steps are rather hard to explain, and are best shown.

Step 1: Gather the parts

Note: Rods are the long, thin pieces and connectors are the pieces they snap into.
Normal colors will be given first, then metallic colors. I used metallic colors where possible when building this particular gun.

For this Instructable you will need:

13 yellow or grey half-circle connectors
2 orange half-circle with knob connectors
2 purple or silver half-circle notched connectors
3 red or dark speckled grey quarter-circle connectors
3 grey one-opening connectors

1 green or black small rod
3 white or silver small rods
2 yellow or dark grey medium rods
3 red or green long rods (note: orange rods are the same size, but they cause too much friction to be used for the pin and do not fit as the side bars. Use of them is inadvisable.)

3 small blue rings
1 large silver ring

2 fat brown rubber bands (#64)
1 long rubber band
&nbsp;&gt;slap back, a little harder, just because I feel like it&lt;
A few months too late man.<br />
&nbsp;Sorry, instructables' message emails aren't working quite like they used to.
I turn the email alerts off lol. &nbsp;Screw that feature.<br />
&gt;&gt;SLAP&lt;&lt; Oops, umm sorry...
&nbsp;Ah. I need them, because I check email way more than instructables...
what&quot;s the purpose of the 2 1-slot connectors?
They keep the front three 3-slot connectors from bunching up. It's optional, but I think it helps friction-wise. If you have bad problems with the shot falling out you can remove those connectors and twist the three-slots slightly to keep the shot in there better.
use a TAN&nbsp;&nbsp;rod as your ram!!!!!!!!!!!!!!!!!!!!!!!!!!! duhhhhhhhhhhhhhhhh!!!
&nbsp;Why? The green rod should have less friction, and it's shinier. :D
&nbsp;actually, tan rods have less friction.<br /> <br /> dude cmon, u should know this:<br /> <br /> gray rod vs black..... hmmm what to choose....<br /> <br /> green/red (same thing), vs tan...... hmmmm what to choose....<br /> <br /> tans are made of the same stuff as black rods and they are the slickest rod knex makes &nbsp;because they are coated in a thin coat of acrylic<br />
Nevermind, I was thinking of the other tan ones. After some rummaging through my collection I figured out that the <em>right</em> tan ones do have less friction. I also figured out that since I only have one, equipping my K'nex arsenal with it is infeasible.<br />
LOL :) did u see my new guns perchance??<br /> <br /> THanks!<br /> -Kev
Yeah, they look pretty cool!<br />
&nbsp;Thanks!! &nbsp;im glad you like them :)<br /> <br /> -Kev<br />
The tan ones always seem to get stuck in my guns because of the weird knobbly things on the ends.&nbsp;
i think it looks like&nbsp; neat gun, just don't have that many rubber bands ^_^&quot;<br />
&nbsp;Thanks! I'll work with one to two rubber bands, and actually feels a lot smoother when you use it like that. You just sacrifice a little on range and hitting power.
o.k. then :)<br /> but hmm...i don't have the yellow piece with knob, guess I'll try to find another piece to replace it<br />
Just use a normal yellow, and stretch a rubber band from that around to the handle. You'll have to fiddle around a lot to get the right tension, but it should work alright.
o.k.<br /> will try it out =)<br />
cool!<br /> just built it, works pretty nicely!<br /> got a bit of power, and fires without flaws.<br /> the best part is, it never jams like magazine guns :)<br />
&nbsp;Thanks!<br /> <br /> Yeah, but the end of the firing pin falls off sometimes. :D<br />
u used a roller coaster kit?
Yep, but just for the orange bits. The rest comes from the ISS set, in metallic colors.
I don't mean to be mean but I would take this down. Sorry
Why? I don't see the point of taking it down.
It's just so basic, I could build it in 3-5 minutes.
Of course. That's the beauty of it! Simple to build, doesn't require a terrible lot of parts, and easy to use.
Sorry but try to build something bigger with a true trigger. I realize you probably don't have thousands of pieces, but please try again :-)
I still have yet to figure out exactly how the whole true trigger thing works...that's still a couple versions ahead. When I figure it out I'll make sure to tell you! I will. Don't worry!
Okay cool!
This is really good, just like most of the other guns like this here. But you have to take this down if you want to be received well here. Sadly, it's true.
Thanks! I don't particularly care If this isn't received well. That's their problem. This is a good gun, like you said...
That's the spirit!
