I found a number of websites where people are selling m16 lower parts kits for less than standard new production lower parts kits. Can I buy these kits and throw away the m16 specific parts without being in violation?

In CA? No, you can not buy an auto sear.

Outside CA? Yes, it's legal to purchase auto sears in most states if they are registered and you have the appropriate tax stamp. Last RDIAS I saw went for well over $10k though.

As far as the M16 lower parts goes, I don't have an answer for you there.

Ask the kids burned alive in Waco. BTW, the "M16 parts" will fit in any standard AR receiver.

Cept for the auto sear. AR 15 receivers don't have that 3rd pin hole.

You cannot make a standard ar15 select fire with the addition of an m16 lower parts kit.

Correct, however I would not want to be in possession of an unregistered auto sear.

My SpikesTac lower has the red pictogram for full auto, I'm pretty sure I'm GTG ;)

Okay, to clarify, the "M16 parts" will fit in any standard AR receiver after a simple modification. The most notable exception are Colt receivers with the sear block. Also to clarify, personal control of a auto sear and a semi-auto AR is constructive possession and may earn you a visit by the ATF.

In additon, under CA laws [PC 16880(b)], mere possession of a select-fire (full-auto/burst) M16/M4 lower parts kit equates to possession of a MG.
Even if the possessor does not possess/own a firearm that the parts can be used in.

Just possessing an auto-sear, with no firearm that can use it, will result in a MG charge under CA laws. [PC 32625]


Penal Code 16880
(a) As used in this part, "machinegun" means any weapon that shoots, is designed to shoot, or can readily be restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.
(b) The term "machinegun" also includes the frame or receiver of any weapon described in subdivision (a), any part designed and intended solely and exclusively, or combination of parts designed and intended, for use in converting a weapon into a machinegun, and any combination of parts from which a machinegun can be assembled if those parts are in the possession or under the control of a person.
(c) The term "machinegun" also includes any weapon deemed by the federal Bureau of Alcohol, Tobacco, Firearms and Explosives as readily convertible to a machinegun under Chapter 53 (commencing with Section 5801) of Title 26 of the United States Code.

Way too much FUD here. Original M16 internal parts are legal. 99% of aftermarket receivers are not machined wide enough or deep enough in the rear trigger well to take the sear. However, installing a M16 hammer, trigger, disconnector and selector will land you in the can. These are original MG parts and not conversion parts. A drop in auto sear IS a conversion part. Just having the 16 parts in your weapon will land you in club FED. The carrier does not matter, the weapon will slam fire even with out the sear.

M16 parts NO, DIAS Yes.

Pay attention...designed and intended

when i had my gun shop down south, i inadvertently ended up with a complete M16 lower parts kit in a deal on a bunch of parts i purchased. fearing that i would get in hot water having the parts in my shop, i contacted a supervising officer at the california DOJ that was our local spot checker and explained to him that i had come into possession of these parts, and i wanted to know the legalities of having the parts in my possession. i was told in no uncertain terms that merely OWNING AND POSSESSING the parts in california, even with owning an AR-15 rifle is perfectly legal, even owning the M16 auto sear itself that comes with the kit is legal. the big no-no is owning a drop in auto sear which is the sear that would be registered. its completely different than having a GI M16 sear as you cant just drop the M16 sear into an AR-15 without machining the lower and drilling the hole for it.......

the illegal part starts when you drill the receiver to accept the sear and pin and route out the pocket in the AR lower

You couldn't "register" an M16 Lower Parts Kit if you tried... DIAS, yes indeed, but they are two completely different things.

nope, and unless they changed the laws in california, it isnt illegal to own a complete M16 lower parts kit, including the auto sear as without an M16 lower receiver or a highly modified AR-15 lower receiver, the lower parts it is nothing more than a conversation piece.

any M16 lower parts can be easily converted to semi auto with a dremel or a grinder..toss the auto sear if it ships with one..even the selector switch can be used if you grind down the center part that activates the tail of the disconnector. just chop the tail off the disconnector and the notch off the back of the hammer..but so far Ive never received the auto sear with a 16 lower kit...

Guys, for clarification. The sear that comes with a M16 lower parts kit is NOT a drop in auto sear.....the sear that comes with the M16 lower parts kit requires drilling a 3rd hole into your lower receiver and THAT would be a felony (drilling the hole) and without drilling that hole you cannot make it function as a select fire rifle.

Unless you procure a drop in auto sear.
