FWIW: NSWC-Crane has shopped out orders for complete CQBR and uppers to Colt. I believe that I've mentioned this to you before in the thread at Militaryphotos.com. -- D.E. Watters
There is no piece of information about the CQBR ammunition : is it 62-grain SS109 (US M-855) or 77-grain Mk.262 Mod 0/1 widely used by Special Forces ? (and is it possible to use 6.8mm Remington SPC ?
I removed the bit about using Mk262Mod1 -- aside from heavier (additional stopping power), I can't understand why a match round would be used in a dedicated CQC firearm -- and naturally the 262Mod0 is unacceptable due to the lack of cannelure.
As of this writing a large percentage of the 5.56 ammunition being utilized by SOCOM in their M4/M4A1 carbines, CQB carbines as well as their Mk 12 Mod 0 and Mod 1s in Afghanistan and Iraq consists of Mk 262 Mod 0 cartridges.
It is possible to modify the gun to use the 6.8mmSPC catridge, would require basically a whole new addon upper and modified magazines -- it wouldn't exactly be an Mk18 anymore. The other issue that would face should likely is the added impulse of the 6.8 -- fully automatic fire would be difficult to control, and potentially undesirable on missions such as VBSS

Mk 262 Mod 1 has a lower threshold velocity for reliable fragmentation than does M855 Ball. The CQBR's short barrel length cuts velocity enough that M855 has a very limited range before fragmentation ceases. The use of Mk 262 Mod 1 in the CQBR allows for fragmentation at longer distances. This is handy if you are caught out in the open while trying to reach your objective. -- D.E. Watters 19:21, 2 March 2006 (UTC)
I found another interesting photo of yhe Mk.18 : [2]. Used by Deltas in protection of afghan president Hamid Karzaï, on september 5, 2002. But it's copyrighted. Do you think it's a good idea to put un link on the main page ?
Do you have any sources or Links?-- Sanandros 15:59, 16 July 2006 (UTC)
It is reported each new M4 as issued to a GI Joe in Iraq or Afghanistan costs US taxpayers 4000 dollars (four thousand USD). That looks like insane. What is the true price? A new AK-47 can be had for 40USD or a barrel of corn some places in Africa. —The preceding unsigned comment was added by 195.70.32.136 ( talk) 10:51, 29 January 2007 (UTC).

The operator's manual for the Mk 18 Mod 0 specifically states that the Mk 18 is a carbine, and its parts include the CQBR upper receiver. CQBR is defined as "Close Quarter Battle Receiver", not rifle.
Ironically, the current Navy citation in the article seems to indicate that the CQBR uppers on the Mk 18 have been exchanged for M4A1 uppers, at least in regards to the Mk 18 issued to ship armories for VBSS use. -- D.E. Watters ( talk) 00:38, 31 July 2009 (UTC)
