Introduction: KNEX XM8 Assault Rifle

Picture of KNEX XM8 Assault Rifle

This is my knex XM8. At first I was making it just as a model then I changed my mind and decided to make it shoot. For me it shoots a minimum of 40ft. It is a very cool gun. It includes basic things such as true trigger, trigger guard, removable mag and scope. Well i hope you like it.

If you want me to post instructions you have to convince me :P

You got the "real" picture of pimp my gun?


Yeah, good day. : )

you mean a real picture of an XM8 assault rifle

You can see it is a digital picture, but it looks the same as the one you can choose at Pimp My Gun.

i know, i do on PMG sometimes and make some pretty cool guns/ weapons.

Yeah me too, but not too much because it gets boring when you do it too many times. =P

yeah it does, but i have made an AK assault rifle and combined it with some parts of an M4/M16

Once I tried to make a bullpup- AK, but that was a bit harder then I thought.
I'm thinking of trying again.
Making bullpups is quite hard tho...

ttarrehs (author)2010-03-17

i just built this but it doesn't shoot but its really awesome

muffinslayer2 (author)2010-03-07

Please post, I would definately make it   5 stars!

combatknex (author)2009-12-08

i dont like it. plain  and simple. stock is wierd fron is wierd mag is wierd its huge and fat. and the grip is curved at the fron? the body is basically a rectangle.

gtrain (author)combatknex2009-12-09

the grip is meant to be curved and most guns have a rectangular body in knex

combatknex (author)gtrain2009-12-10

yeah. you did do a very good job on the back half. i rated a 4.5 for your effort and it doent even look that bad my only issue is the sloppyness of the curved rail. and i bet its going to be very hard to get that rail perfect

knexpete (author)combatknex2010-03-05

 im sorry, but gtrain has made an excellent piece here. it's accurate to the gun, it's very very very good
6* (if i could give it that many)                                                                                    AND ONE THING.............................................POST IT!!!!!!!!!!
