Velocity Arms S System M4

[jopamac]

Hey there boys and girls,
Just got my V.A. M4 a few days back, and I need some opinion.
I'm considering painting her up, but I fear I will cause damage to the gun. I only want the stock and fore grip painted, which meant's I have no worries about ruining the internals. Only one issue, the fore grip is the variety which has holes in it (it's the m4 from MW2 to help you picture my situation) I can remove the bottom half of the grip, as it is the battery door, but I am having difficulty removing the top half. I don't want to paint with the grips attached to the gun because I fear collateral painting as well as paint getting inside the battery housing as well as what I think is caused the fuse box(forgive me I'm a noob). Anyone know any way to help me out?
Attached is the interior of the fore grip

There is 3 (or 4) screws on the top rail that needs to be removed.

Then, remove the battery, turn the gun upside down and remove the smaller screws inside the rail. Should have 4.

Just cover it with paper or plastic and painters tape
