Colt 6940

And they are.

It's not a bad trade off, free float rail for not much more weight than a drop in rail.

I love my 6945.

That will not work. The sight base needs to have a milled out slot for the locking tab to interface with that isn't present on the original non locking 6940 front sight base. At least not that I'm aware.

My front sight base DOES have the milled slot, I just need to know how to remove the front sight. Any armorers/gunsmiths know how to remove it?

That's odd. Must have been a weird transitional thing where they were just trying to use up parts as Colt likes to do even if the combination makes no sense.

Can't say I've ever removed the flip up sight post from the base and I'm sure some special tools are required. Could check with Specialized Armament as I'm sure they know the procedure.

Does anyone know how to remove the Colt 6940 folding front sight (not sight base)? I want to replace the original non-locking front sight with a newer locking front sight. I have the locking front sight which Colt provided for FREE! The pivot pin retainer clip is surrounded by a lip which doesn't allow it to slip off - how do I get the clip off?

But doesn't the non locking actual sit in place in a very sturdy manner? What made you even notice it. I'm not sure if mine locks or not, but I know its tight AF. Going to check mine now. But mine is 6945, same difference I think.

My first AR was a 6940 and it shot very very tight groups. I started with the wrong idea about AR's.

EDIT: mine is definitely locking, I had to fight that SOB to get it back down.

Mine from 2009 doesn't have the lock latch, but it is the most secure spring detent folding sight I've ever used. But even still, if it got knocked from the front it could fold. This doesn't bother me, but I guess it was an "issue" enough that Colt felt the need to include the latch.

What the hell, if its free AND you can instal without buggering up the FS, go for it. Keep us posted.

Yeah.. I doubt I'd take the beating of changing it out, but to each their own.
