Difference between Mk18 and CQBR:

Whats the Point?

People often confuse the VBSS Mk18 and the SEALS CQBr , I hope to clear some things up with this description of the two rifles. I am basing most of the info on research posted on arnies and fact checked by hundreds of internexperts on the subject. I supplied the manufacturers info.

The Difference.

A Mk18 is a complete, assembled weapon used by NSWC (navy surface warfare center) for their special teams. The SEALS CQB/R on the otherhand. is an issued upper assembly kit that is meant to retrofit M4A1s already in service, outof the SOCOM SOPMOD kit. Basically CQBr is a kit of bolt on replacement parts made by various companys specifically to fill a gap in the SEAL armory between the Mp5 and the full length m4. NSWC saw the brilliance in the rifle and built ready made versions for their teams (and named it Mk18).

Thats the short answer. Mk18 is a whole gun, CQBR is a new upper assembly for an old gun. Both are made by different companys, but look nearly identical.

So whats the confusion?

The CQB/R is used by SEALS on VBSS missions (Visit Board Search Seizure). The Mk18 is used by Navy VBSS teams (think navy swat teams), NCIS and others under direct NSW command. This is perhaps where the confusion comes in... anyway. ,, /

The Mk18 is assembled by NSWC armory, but manufactured (mostly) by LMT ( Lewis Machine & Tool, a few other comps contribute parts like Colt, CQD, etc. this is common in govt contracts)

SPotting the difference in photos:

The Biggest difference is that the CQBR is built on an M4A1 lower, whereas the Mk18 uses an M16A1 (styled) lower (you can tell because the cut near the front receiver pin is not rounded but a harder edge cut). Mk18s have CRANE markings on the right side of the lower receiver, on the magwell "in white laser engraving". There's also specific markings on the upper receiver as well. It's all real subtle, but it's there.
