| I just built up a lower and put in the selector switch. The thing will not move! I started messing around with it and found the only way to move the switch is if I apply pressure from the other side of the switch (where the round part sticks out of the receiver). Is it out of spec or did I put it together wrong? Also, i have a full auto switch spare. Can I put that in legally? Please help! Thanks! |

New parts kits are always Hard/Sticky when new, then break-in over time and use. Take the selector and detent out, if the "track" on the selector looks good, you can stone the point of the detent down slightly, lube both and re-install. No you can not use a full auto selector in an unregistered lower! I dont think you can even own one without a registered classIII lower. |

See if there is something in the pistol grip spring channel that is causing the selector spring to be totally compressed. Also check the tip of the detent against the selector detents to make sure that it can glide in/through the detent. If needed, just dull the tip of the detent a bit to allow it to glide if the spring being fully compressed is not the problem. As for the full auto selector, yes it can be installed (an A-1 M-16 selector), and you will just have Safe, Semi and still Semi in the full auto position. Since the semi disconnector tail is cut, the disco will not be cam'd out of play in the full auto position, and all is still good (that is if you want to be a poser with you amps going to 11). Note: you change out the disco to a full auto unit, which would require an M-16 open back end trigger to be used, and you going to pop with intent to create a machine gun if you have the right combo of parts, even without the auto sear installed. |

With regards to the legality of a full auto selector lever in an otherwise stock AR-15, I would take a gander at the quoted ATF guide excerpt and research it yourself. People have been put in Federal Prison or worse, killed over a bad interpretation of Federal Firearms rules and regulations. Just a thought! Heck, an assembled short barreled upper receiver by itself can get you in deep doo doo if you are also in possession of an unregistered lower (i.e. not registered as SBR or Machine Gun). Take it with a grain of salt!hichmore than 1 shot without manual reloading, by a single function of the trigger, is a machinegun as defined in 26 U.S.C. 5845(b), the National Firearms Act (NFA). The definition of a machinegun also includes any combination of parts from which a machinegun may be assembled, if such parts are in possession or under the control of a person." |

Be4uf, Welcome to the site!!!!! As for the discussion on what construes intent to create a Machine gun, we here at the site have been hashing over it for years. Really what it all boils down to is through the use of certain types of ammo, you can get the rifle to fire more than one shot with hammer follow through. Certain parts alone will not allow the hammer to achieve this, but the combo of parts will. The big rule given is that you do not drill the auto sear hole, or install an auto sear in the rifle. Both of these are well past the intent, since you have produced a MG even without any other parts. As for some other select parts, here again, it's not the single part, but the combo/ or lack of parts (don’t even need any M-16 parts for this) that can get you into trouble. Bottom line is not to set the rifle up to go Zoom-Zoom all by it's self, or to take the rifle into the gray area where it is Rdias ready to go, even if its a Host rifle with the Dias in another host. |
