Ok, so I made some mods to my AR-4 v3. There are 3 major mods, a couple of other minor cosmetic mods, and one performance mod. Picture 2- minor stock mod. This mod allows people to extend their stocks to make it longer. Picture 3- New hopper based off of Killerboy's removable mags. Major mod. By using his hopper as a fixed mag, It now allows me to hold 9 yellow rods, which is pretty big. It does jam, but rarely. The rounds will all stay in the hopper if you vigorously shake it, and you can remove the rounds pretty easily. Picture 4- Minor trigger mod. All it is is replacing the hinge with 2 Y connectors, a white rod, and a purple one slot connector. Picture 5- Scope mod. This connects the scope to the top of the gun, making it a better hand grip for carrying. Picture 6- Yet another scope mod. This mod was made to adapt to the new fake barrel, which was filled up instead of only the middle row having the orange connectors. Picture 7- Mod to the bottom of the gun. The last one was just having blue rods, this one fills it up with connectors. Picture 8- Foregrip mod. This is the second of the 3 major mods. I did away with the bipod and modded the bottom to have a new grip. Mainly a comfort mod. Picture 9- Barrel mod. The last major mod. This mod was made after several people noted that the ammo needed some 'Help' to get into the barrel. I basically just filled in the hollow area where the ammo would jump from the hopper to the barrel, so you dont have to stick your finger in. Picture taken from top of gun. That stuff above it is what you connect the scope to.
