RandomCommenter (author)2015-06-20

How do u load the magazine quickly when I put in ammo it turns to weird angles making it hard to load.

Great gun BTW.

i made the first comment on that step

What is the difference between the black rods and the grayish rod, are the black rods heavier or something

Sharir1701 (author)jiansy2012-07-13

allow me to add more info. the grey rods are just plain plastic, which is quite easily bendable and breakable even. the black rods are a stronger type of plastic reinforced with internal fibers, causing for a much stronger piece. they are often used for rams in knex guns because they don't bend or break. they're more reliable than the normal grey rods.

Oblivitus (author)jiansy2011-07-03

They are sturdier and much harder to bend and break.

Element Force (author)2012-07-09

what is that black thing in the 2 pic

Oblivitus (author)Element Force2012-07-09

A Y-connector.

Element Force (author)Oblivitus2012-07-10

BillThePlatypus (author)2011-05-18

rrr67 (author)2010-08-06

are there supposed to be 2 green rods on the bottom row?

JB123 (author)2010-05-08

HELP! I did everything right but when I put the black rod thing in it wont go in PLEASE REPLY

Oblivitus (author)JB1232010-05-08

You have attach the yellow connector that pulls it after you insert it if you didn't build it into the gun during assembly.

TheEvilCookie (author)2010-04-06

do the bullets get caught inside the barrel and you have to take off the whole top to get it out like the last mgs?

Oblivitus (author)TheEvilCookie2010-04-07


TheEvilCookie (author)Oblivitus2010-04-09

u sure? cuz the last one got bullets stuck 1/2 times

anres321 (author)2010-04-06

 Nice builded !! but how do you make those diagrams ???

Mr. Muggle (author)2010-04-04

On what poinst is it improved than MFS by knexfreek

Oblivitus (author)Mr. Muggle2010-04-04

It's simpler, more comfortable, doesn't use cut parts, has a thinner mag, and the mag pusher won't break if you dry fire it.

Mr. Muggle (author)Oblivitus2010-04-05

Ok, good, I think I'll build after posting my chair v2!

cool bas3 (author)Mr. Muggle2010-04-05

Oblivitus (author)Seleziona2010-03-28

The same as the original. About 20 feet with gray connectors, more with socket connectors and green rods. The video will be up by tomorrow.

Thanks and no thanks. The funny thing is that I finished the improvements only a few days after you posted yours, lol. I horribly procrastinated on the instructable because I got stuck at the assembly step.
