What holes are people refering to when they talk about colts having large and small pin diameter or holes.

The front pivot pin on the lower receiver

Hammer and trigger pin holes in some cases, take down pin in others.

ETA - front pivot pin and take down pin in this case refer to the same thing.

That would be the trigger and hammer holes.

Just remember, if it feels too tight, check to make sure you have the right hole!


Sorry, I saw the title and couldn't resist...

It's the hammer and trigger pin. I've never seen a Colt with a different sized take down pin.

From Bushmaster's parts index: Reverse Offset Pin

Adapts a Colt upper receiver (large hole) to push pin (small hole) style receivers.

The standard M16 uses 1/4" diameter takedown and pivot pins
In order to discourage the use of M16 parts in AR-15's, clot took it upon themselves to change the pivot pin (front pin) to 5/16" in diameter and offset it.

Then you have trigger and hammer pins...
These are nominally 5/32" in diameter or 0.156"

In order to stop people from using M16 fire control parts, clot increased the diameter of their pins to 0.169" to keep us safe from the rampant urge to make an illegal machinegun.

If you avoid clot, you won't have any issues with non-spec pins.
Only clot owners have to deal with this.

A clot is something that slows down the flow of blood.
In our case, firearms are the lifeblood of freedom.
Colt is something that slows down the flow of freedom by deciding to change parts to "protect us from ourselves"

They make a great gun.
They should stick to the original drawings though and stay out of politics.

You have to consider the political climate at that point in gun-owner history

Had Colt not done something, they may have been looking for a new line of work.


Government would have come up with something a lot more sinister than pin sizes, sear blocks, and semi-circle carriers.
