Ok here's the deal. I know most of us have m4's (except for snake eyes because... well its snake eyes and he is in love with his G36) and if your like me you like upgrading and fixing your gun, but OH NO! you don't know what your doing and end up wrecking your gun. That's where I come in.
I mostly work on my M4 so that's all I'm really comfortable with. SO if your M4 is broken or you just want to have new parts installed shoot me a text (pm for number if you don't have it).
I am willing to dabble in other gearboxes (cept for your G36 Snakeeyes and you already know why) so if your looking for a tech lemme know.
No GBB's.
