Knex M4


Introduction: Knex M4

this is so far my best knex assult rifle.
The gun has a curved removable mag,or a no-jam straight mag,and true trigger.

This guns can reach about 50ft MAX.
I will not say it never jams because it does,but not very often ,like 1 every 3 clips.
the trigger may fail every like 100 shots fired,or by too much rubberbands.Enjoy!

Step 1: Barrel

ok this is the barrel it is very plain and simple.
It may seem a tad complex but you should be fine.

Step 2: Handle

This is the guns handle the easiest steb aside from the trigger

Step 3: Inner and Outer Body

probably the hardest step of the gun maybe because the stocks really hard to...

Step 4: Top Rail

not hard at not going to post much pics because so easy just look at intro pic k?

Step 5: Stock

this is the second hardest part

Step 6: Mags

two kinds of mags the straigh one jams less the cured jams more often.

Step 7: Ramrod

self explanitory

Step 8: Trigger

very easy

Step 9: Putting Together Back Half

stock trigger and handle

Step 10: Front Half of Attaching

attaching front barrel and finishing second rail system

Step 11: Yayz Done! (kind Of)

ok well you get it

    are you used to seeing the yellow half circle connectors?

    half circle connectors? which grey bits?

    office supplys menu? whats that?

    I was wondering, do you need to have the ball connectors for the mag.

    no offense, but the stock is too big and the body is too small (in height) and the handle looks ordinary.
