Centurion Modular Rail (CMR) picture and info thread (add your pics)

Any guesstimate on an inner diameter for this?

This one looks to be just the ticket to replace my missed comfortable URX3 and a balm for Geissele's dissapointing production revision of the proto MK4. (Only because the original design was so gorgeous. Not knocking function.)

Is the combo 14.5/14" in shown photo?

Monty w/ another Home Run...I think this just took the lead ahead of the mk4.

Already have a full Monty built w/ a C4 so this will be a progression of my loyalty

Hey Stick...pictured is a what lenght combo???

Great as always pics...thank you Sir

[jonconsiglio]

What other lengths are coming? Will there be a 10"?

[Stickman]

Did they release the MSRP?

Stick, does that light mount screw into the rail?

No idea on actual price, sorry.

Yes, the mount screws directly in, no backer plates or anything like that.

Pretty narrow, I'll see if I can find a tape measure.

With the barrel nut installed, slide the end of the rail into place. It may take a firm press to lock it up against the receiver, and it is normal to have a tiny space in between the two parts. Now use a 3/32 allen head wrench and install the 3 screws. There is no need for thread locker, but you should alternate tightening each screw and side just like you would a lug nut. Watch your alignment on the top of the rail and your receiver, but we found everything lined up perfect ever after we took it apart a few times.

Why no need for thread lock?

Also, unless I missed your answer, is the one pic a 14.5" barreled upper with a 14" rail?

And, thanks for the update...I've been eagerly awaiting these and will be getting a 12" as soon as I can.

Are the QD receptacles rotation limited?

Currently all of my carbines wear Centurion rails so I'm biased. I will have to put one on the bag of parts I've been accumulating for the last year. Almost 100% Noveske except for the BCM bolt and carrier. I used the Troy tubes for several years and liked the narrow profile and light weight.

A question if anyone has the answer. I know Centurion is a fairly small operation but I'm curious if the owner comes up with his ideas or there is a small R&D or engineering department? Just curious is all as they (Monte) has really come up with a few "better mousetraps" in my opinion.

Are the QD receptacles rotation limited?

Yes, they lock in place positioned from 12 to 6 o'clock, or from 3 to 9 o'clock. It just goes to show the attention to detail put into the rail.
