Yup, this thread has burned out...

Yep, we're not going to learn anything new unless Colt posts the answer.

Until that happens this thread is dead.

Well, I can give you new measurements...

Rear of upper receiver to top of RSB (by windage marks, where bottom of aperture rests):
RRA flat-top with BM DCH = 2.833"
Colt MT A2 = 8.824"

Center of bore to FSB flat:
RRA 16" middy = 2.290"
KPF .22LR 20" = 2.290"
Colt MT 20" A2 = 2.310"

I didn't expect the Colt A2 to measure different from the others. It would seem to be about half way between the standard and the "F". I wasn't really expecting the rears to measure different by that much either. Hard to measure the rear though, so maybe that's in the receiver's rear curve.

standard FSB is 2.285" +/- 0.010"

measure from the bottom of the RSB to the center of the windage screw.

So the definative answer to the question of why Colt changed the sight height is . . .

. . . only Colt knows for sure.

I want to believe that they had a really good reason to give us a world of 2 different front sight platforms, but it's hard to come up with a really good possible reason.

Yes.

Don't forget that they also gave us a taller DCH/rear sight.

I also want to believe that Colt had a good reason for the taller sights.

Quoted:
Bushmaster carry handles are shorter then Colt/Mil-SPEC

Bushmaster does not use taller front sight posts on their flat top rifles and carbines. If you were to use a Colt carrey handle or MIL-SPEC BUIS an a Bushmaster flat top rifle or carbine you would have to use a taller front sight post.

Also, there is no apparent reason that I have found for Colt/MIL-SPEC removable carry handles and flat top FSBs to be taller than Bushmaster's non MIL-SPEC versions.

And yes, Colt's are "MIL-SPEC".

This post is TOTALLY incorrect.

Nevermind. I was wrong.

it was theshootersden who did all the measuring this time around

And I'm still the knucklehead who's going to look for a different height/width front sight post if I can't get what I have to zero properly. This is a lot like handgun stuff. "That's too tall. How about this?"

It is also a little better than counting angels on the heads of pins, but not much.

I have an RRA M4 LAR flat top with ARMS 40 rear (Trijicon insert) with a YHM front (Trijicon insert) , EoTech, blah ,blah.

It all lines up. Thank God, or I would have to kill myself.

A question, not a hijack: So, on a practical note. How many front post configurations should someone keep for a range/training box? I'm thinking 3 or 4 in the parts box. Right now I keep basic trigger assy, lower kit, addl lower parts, pins, etc, common stuff.

Thanks,

Rick

And now back to the regular thread, Is there a difference between a Colt and a Bushmaster Carry handle.

Wow, we have come a far piece.

I cant believe I read this whole post, feels like I've been dry heaving for the last hour.
