My SEGV-2 (Shell Ejecting Gun Version 2)




About: I used to build K'nex guns. I'd like to think I've grown to be quite good at it, however, I've lost most of my interest in K'nex over my first couple of years in High School, but I do occasionally still come...
I have been searching the web for a good shell ejecting gun for quite some time now, and i haven't found one flawless model. so i decided to try and build my own. i had a first model which didn't have a body, a real trigger, or a handle, and the mechanism was very sad and full of flaws. a few days later i had a new mechanism in mind, but just in theory. i had to find the correct parts to use with this mechanism and i also had to find a suitable body for it. eventually, after almost 2 days of building, taking apart, building and repeating many many times, i found the correct way to do it. it's got no flaws so far. it's very sturdy and it always ejects the shells straight away, without any help at all. the bullets always come out straight and powerful. i really like the final model for this gun, and i hope you do too !!!

good shape
strong, got it to shoot 67 ft
very, VERY low piece count
comfy handle
magazine ram never breaks, stops just before where the ram goes
very easy-to-use ram
everything is very sturdy
easy and comfy reload
real, flawless trigger that never breaks
awesome shell-ejecting feature
nothing ever breaks, if used correctly
small, easy to transport

top-front part of the gun isn't symmetrical (this is needed for shell ejection)
uses a lot of rubber-bands (ignoring ram-bands)

    It's old now and uses the barrel style that I don't care for, but what was the flaw with my shell ejection system? It was a tad cleaner. This is a good start but a little messy for my tastes. Either way, keep it up.

    i never found your gun... maybe you should add more tags to it, cause i searched good for shell ejecting guns, and never found yours

    It wasn't a posted weapon. I don't recall where I had it but let me see if I have the images. Yup, I found them. This is old so it could be improved, but it's still very reasonable.

    did you think of posting instructions for your gun? i'd like to see it from an inside look...

    I made something like this about 2 years back, but it was sturdier and bulkier and you could load the mag from the bottom. To give you credit though your trigger blocks farther back than mine, but not by much. Here's a pic of mine.
