I have done work on guns for a while now. No I am not a master gunsmith. It started just cleaning guns of my own, then to cleaning other peoples guns, then to complete dissaembly of most guns for a legit cleaning. then it went to attaching scopes and boresighting, to adding small mods such as weaver rails, flashlights, etc etc, then to actually taking a stock smith and Wesson mp15 and upgrading more than just a scope or pistol grips or things of that nature and actually working on the gas port, and the trigger etc etc.and so now I am trying to take the next step which is why I asked those questions on the other post. I like knowledge. I don't just jump right in on something. So if you wanna say I have done little gunsmithing sure but ya gotta start somewhere . As far as the SKS goes, this is just a potential cool gun to make a project out of if the owner wants to and I wanna get as much knowledge as I can before I get into it. and it looks like its just gonna be a simple muzzle break and a scope that's it. I convinced him to just let me freshen it up, clean it, and just add 1 or 2 simple mods that's it. some guns shouldn't be all blinged out with accessories. especially an sks.
