View Full Version : Question about AR hammers

I was looking at a couple AR hammers I have sitting around and I noticed something weird between them. A couple of them look like the picture below where the hook for the disconnector is flush with the rest of the hammer.

On some though the lip for the disconnector sticks out about twice as far to the right. It looks like it's completely unnecessary and that the disconnector wouldn't need it at all. Does anyone know why there is a difference between the two?

From the angle of your photo, that might be a full auto hammer. The parts shown below are for select-fire M16 rifles

Full Auto for sure.

yea the tail on the hammer is for a full auto

what the switch does is push the disconnector down and then the autosear becomes the disconnector and is tripped when the bottom front of the rear of the bolt carrier hits it

if you want to use it i would recommend filing that bit down

ps someone put the spring on that trigger backwards

Does "Constructive Possession" apply here? If it does there might be legal issues involved.

Wouldn't chance it. Just toss it, but a different one. It's about $10.

Yes.

That's a machinegun part. Period.

Either: Toss the hammer and get a standard semi-auto hammer, or take a grinder to that hook.

Take a look at the trigger too. If it's got an open-back, it's also an M16 trigger and you should get rid of it. AR15 triggers are closed off in the back to prevent you from using an M16 disconnector with its extra-long tail.

Alright, I picked a bad picture.

non full auto hammer. The lip for the disconnector - the triangle looking part about half way down the picture.
That sticking out to the right - past the right side of the hammer - making it not flush.

i thought constuctive possession meant you had all the parts to make it full auto

just a hammer and a trigger wouldn't make a gun go full auto

but just owning a pistol barrel and an ar-15 rifle would be as you have all the parts to make a short barrel rifle

but i'm not a lawyer

Probably because they're using the same basic mold to cast the M16 hammer as the AR15 hammer.

For 4-position guns there are two disconnectors side by side.

Yes, that is a full-auto hammer. Do not have that near your guns at all........
