How does someone make the foregrip for an M4 without using a ridiculous amount of yellow connectors?

I'm trying to make an M4A1 but I'm stuck on the foregrip/barrel I want to make it as accurate to the real thing as possible, but I don't want to use a lot of yellow connectors. Ideas?

Use ironman rails.
Use a ridiculous amount of red and green connectors.

I looked on Google to check what an M4A1 is; (a machine gun for those who are as clueless as I was). There's nothing yellow on I'm wondering why you specified yellow connectors as you want it as real as you can make it - and can you be more specfic as to what part you call the Foregrip? (I'm reckoning it's the grip around the muzzle?)
I just saw the 'ible for it... lots of yellow I see! Well, if you want it realistic, are you sure you want to make it out of knex? Maybe I just need more info....?
