    www.tapco.com panther/DPMS also make themso does bushmasterAll NFA rules apply thought.In order to convert an AR15, takes some clever milling and the proper paperwork.Unfortunalty since the 1989 assault weapons ban, you can no longer do it legally.Don't forget you'll also need a full auto bolt carrier.Your looking at about $300-400 in parts plus another small fortune to find someone to mill your reciever to accept them.

    I have no idea what an "AR-15a" is, but I assume that it is a semi-automatic rifle. The 3-shot trigger mechanism is considered by BATF to be the same as a full-auto mechanism. Possession of it and a semi-automatic AR-15 could be considered possession of an illegal machine gun, good for up to 10 years in a Federal jail.Think about. If it still sounds like a good idea, think again.Neal

    The ban on additional, new civilian-owned full-auto firearms was part of the 1986 Firearms Owners Protection Act (not the 1989 import ban, which applied to military-style semi-automatics only), which froze the number of civilian-legal full-auto firearms as of the date of enactment. Since that time, no new full-auto firearms may be manufactured for sale to civilians. While prior to 1986, one could do the paperwork and manufacture a full-auto firearm by converting an AR-15, etc. to full auto, since 1986 one cannot do so. If one has a legal pre-1986 full-auto AR-15/M16, I believe one may modify it at will, including adding a burst kit, without further paperwork. One may not legally add those parts to an AR-15. Back when it was legal to convert an AR-15 with proper paperwork, an M16 trigger, selector, disconnector and bolt carrier were required, plus some way to trip the sear. The sear operation was either handled by an "auto-sear", which required no machining of the receiver at all, or by installing a M16 auto-sear, which required drilling only one hole through the receiver just above the selector. Jigs were sold for that purpose to properly locate the hole. (I have not thought about this for a long time, and it may be that some metal had to be removed from an AR-15 receiver to accept the M16 auto-sear. Can't remember for sure.)As already stated, none of this can be done legally by civilians now.

    Instead of doing all of that, you might want to try shortening the reach of the disconnector in the trigger group. Then the hammer will drop from the disconnector hook when the trigger is released but will not be caught by the nose of the trigger, causing a second shot to be fired.I do not know if this will work or if its even legal. I have not taken a look at the AR trigger assembly, it was something I read awhile back.If it is done and is legal, the rifle will be VERY dangerous to a person not knowing it was installed.

    What The Gun Doctor suggests cannot work with any but the earliest AR-15, and generally will not work with those rifles either. On most AR-15 rifles, the bolt carrier and hammer are designed to catch each other and prevent the hammer from following the bolt and striking the firing pin if the hammer is not held by the disconnector (either due to modification or removal). On these later rifles, the hammer has a notch in it designed to catch a lip on the bolt carrier if the hammer is not held back by the disconnector, thus preventing the hammer from following the bolt closed.The very early AR-15 rifles had hammers without the notch, but removing the disconnector from those rifles generally still will not allow the rifle to fire full auto because, when the hammer follows the bolt forward, it will not hit the primer hard enough to fire the cartridge. Any modification intended to make a semi-automatic fire full-auto is illegal unless the proper paperwork was completed prior to 1986 when such a modification was legal.

    It is fairly simple to change a SA to a SelectFire.But illegal as hell since your government doesn't trust you.cpermd
