Introduction: Knex M4A1 / M4 Carbine Assualt Rifle

Picture of Knex M4A1 / M4 Carbine Assualt Rifle

DO NOT BUILD THIS if you want a gun that shoots good.  Build this ONLY if you are going to keep it for looks.  Do not judge this gun based on its shooting.  It was made purely for looks.  It jams frequently and only gets about 15 ft unless you take off the stock, then it gets about 30 -40 ft and does not jam.  If you want a gun that shoots good, make my intervention.  REMEMBER: RATE THIS GUN BASED ON IT'S LOOKS, NOT IT'S PERFORMANCE.  IT'S A REPLICA.  IT SHOULD BE RATED ON LOOKS, NOT PERFORMANCE.

Now, you may be thinking...
WTF?  This looks nothing like an M4 Carbine!

Thats where you're wrong.  In this step i'll show you how to attach the attachments like the carrying handle for example.

1) Carrying handle / Iron sight
2) Red dot sight

Jaren000 (author)2013-08-11

will it still fit together if i remove the firing system? because i don't care at all if it shoots. i just want it to be accurate and this, my friend, is epic.

knex obsessed (author)2011-07-29

Now i have built this gone for the second time, im gunna SOPMOD it :D,
for you guys that dont know, a SOPMOD, is a Red Dot Sight, Grenade Launcher and a Silencer, and also the M4 carbine and the M4A1, are the same set of guns but different, The M4 Carbine has a little more power, whereas the M4A1 is more for its accurecy

sharpshot13 (author)2011-01-29

Its a great gun but when I try to shoot it the barrel stops the "bullet".

MotaBoi (author)sharpshot132011-02-11

Yeah, that's the worst part about the gun, but you should have read the description ;)

dansdoc (author)2010-10-26

MotaBoi (author)dansdoc2010-11-12

It's 2 Y connecters put together.

dansdoc (author)MotaBoi2010-11-12

MotaBoi (author)dansdoc2010-11-12

The front of one clips in to the back of the other.

dansdoc (author)MotaBoi2010-11-13

then it cant attach to both peices

Senior Waffleman (author)dansdoc2010-12-13

its in a link, theyre attached like a chain and then to the yellow rod

dansdoc (author)Senior Waffleman2010-12-14

they cant both attach to the white rod and yellow rod at the same time!

Senior Waffleman (author)dansdoc2010-12-15

dansdoc (author)Senior Waffleman2010-12-16
