This particular sear is for an FN FNC (FN stands for Fabrique Nationale, an excellent Belgian maker of firearms). The FNC, while in many ways being functionally similar to an M16 / AR-15 is a very unique, confusing and often misunderstood rifle. Of course, that's why I chose this one.
Now, I'm going to go all wonky technical on you here, so you can stop reading if you choose, I totally understand. Where the AR-15 and other similar military style semi-autos have a lower receiver which is the serial numbered part of the gun (making IT and only it the actual gun by law), the FNC's upper receiver is the serial numbered part. In 1986, the Gun Owner's Protection Act (f-ing **** name) made all machine guns manufactured after May 1986 or semi-autos converted after 1986 illegal and unable to be added to the NFA machine gun registry. This means that AR-15 lower receivers can't be drilled and milled to accept a full-auto sear after 1986 - totally illegal to do this.
But, a Semi-auto FNC lower receiver CAN be drilled to install a full-auto sear, if that sear was made and registered per the NFA before May 1986. And a company (Flemming) made and registered ****-loads of these full-auto sears as "machine guns" before the 1986 deadline - crap, just look how simple that piece of metal is!
But, here's the rub. In 1989, George HW Bush signed a law that prohibited the import of semi-auto military style weapons. The FNC could no longer be imported after that date. So, there's a very limited number of semi-auto FNC's out there and a bunch of these sears owned by somebody which have been registered. Any semi-auto FNC can be legally converted TODAY into a fully functioning machine gun, if the owner of the "host" legally purchases the FNC sear which is the legal "machine gun" according to BATFE. The FNC, unlike the AR, can be modified today because the lower receiver, i.e. the part of the gun that would be modified to accept the sear, IS NOT THE SERIAL NUMBERED PART, and therefore not a gun, just a gun part. And, BATFE does not regulate modification of gun parts.
