[Last Edit: Lancelot]
When discussing the Mk 18 / CQBR program, we can divide the history and discussion in to two distinct categories: 1) The weapon system itself / upper receiver supplied and 2) the group of accessories deployed on said weapon systems (SOPMOD).
---------- Mk 18 Mod 0 / CQBR The M4 carbine and M16 are not ideally suited for all missions, so it was proposed that the modularity of the M16 series would allow a user to replace the upper receiver of an existing weapon with one more suitable to the task. One of two proposed special mission receivers that were planned for inclusion into the SOPMOD Block II kit, the CQBR has taken off on its own. Like the proposed Special Purpose Receiver, the Close Quarters Battle Receiver has been more or less taken on by the Naval Surface Warfare Center, Crane Division (often referred to as NSWC-Crane or just "Crane") as its own project following the CQBR's removal from the SOPMOD program. Just as the Special Purpose Receiver morphed into the Special Purpose Rifle, and was type-classified as Mk 12 Mod 0/1, the complete CQBR-equipped carbine has been type-classified as the Mk 18 Mod 0. The purpose of the CQBR remains to provide operators with a weapon of submachine gun size, but firing a rifle cartridge, for scenarios such as VIP protection, urban warfare, and other close quarters battle (CQB) situations. The CQBR is designed to provide improvement over previous AR-15/M16-type weapons in this category. The CQBR is usually issued as a complete weapon system, and not just an upper receiver. The CQBR was once only available to Naval Special Warfare units, but the Mk 18 Mod 0 has become general issue for Visit, Board, Search, and Seizure (VBSS) missions and, as of 2006, for NCIS agents deploying to active combat zones.[citation needed] The Mk 18 is also used by the Coast Guard's Tactical Law Enforcement Teams, Maritime Safety and Security Teams, and Maritime Security Response Team and the United States Navy's Explosive Ordnance Disposal (EOD) Operators. Wikipedia has a good article with sources on the original CQBR/Mk 18 Mod 0 and its development. ---------- SOPMOD The SOPMOD Program Management Office at NSWC Crane, IN, provides standardized, versatile weapons accessories to meet needs across SOF mission scenarios. These accessories increase operator survivability and lethality by enhanced weapon performance, target acquisition, signature suppression, and fire control. The CQBR itself was originally part of the SOPMOD program as an accessory replacement upper receiver for the M4. However it was eventually separated out into its own project. SOPMOD accessories for the M4/CQBR originally included things like the KAC RIS/RAS, SOPMOD stock, KAC M4QD suppressor, AN/PEQ-2 illuminator/laser, ECOS-N red dot, ACOG, etc The SOPMOD program has gone through multiple minor and major evolutions throughout its lifetime. The most significant is commonly defined as "Block II" and included the introduction/replacement of accessories that met the updated needs of operators. The most visually significant "Block II" accessory is probably the replacement of the KAC rail/FSB with the Daniel Defense RIS II free float rail with low-profile gas block. Other updates include things like the Surefire SOCOM sound suppressor, EOTech RDS (553/SU-231 & EXPS 3-0/SU-231a), LA-5/PEQ ATPIAL, etc ---------- Link to docs and photo albums Presentation on CQBR from Crane Operator's Manual for Mk 18 Mod 0 SOPMOD Program Overview presentation from Crane Photo Album of Mk 18 Mod 0 Photo Album of CQBR with SOPMOD Block II accessories ---------- Because of the long history of both the CQBR/Mk 18 and SOPMOD programs, it's common to find weapons with various mixed configurations in the field, all depending on what time and unit the weapon system belongs to. Below are a few examples with descriptions to illustrate this. Example of a Mk 18 Mod 0 in as-issued configuration including: M16A1 surplus lower receiver, SOPMOD buttstock, KAC RIS, KAC M4QD flash hider, Aimpoint Comp M2 in Wilcox mount, LMT rear fixed sight, CQD rear sling plate. NSW Operator CQBRs with original SOPMOD accessories including KAC M4QD sound suppressor and AN/PEQ-2 IR Illuminator/Laser. Member of a Combat Camera team with a CQBR with KAC RAS and M4QD flash hider but with other updated accessories from the "Block II" SOPMOD kit including SU-231a (EOTech EXPS 3-0), EOTech G33 Magnifier, LA-5/PEQ ATPIAL, Insight WMX-200. Good example of "early" CQBR with SOPMOD Block II accessories including SU-231 (EOTech 553) and SU-233 (Insight M3x weaponlight). Example of a more "modern" CQBR with SOPMOD Block II accessories including the updated SU-231a (EOTech EXPS 3-0) and Insight WMX-200 weaponlight. Many times certain configurations are common within certain branches/groups. Here a Marine Raider is seen with a CQBR with an AN/PEQ-16 (USMC issued vs. the LA-5/PEQ SOCOM issued ATPIAL) and KAC NT4 suppressor (vs. the current Surefire SOCOM suppressor). ---------- Building a clone If you're interested in building a "clone" of a Mk 18 or CQBR equipped M4A1, here is a basic parts list to use as a guide and get you started. This list is not exhaustive and see the * note above regarding personalized accessories. | Mk 18 Mod 0 | M4A1 CQBR Block I | M4A1 CQBR Block II Lower Receiver | Mil-spec forged A1 | Mil-spec forged A2 | Mil-spec forged A2 Stock | Gen 1 SOPMOD (Black) | M4, CAR, SOPMOD, CTR & others | M4, CAR, SOPMOD, CTR & others Pistol Grip | A1 | A2, ERGO & others | A2, ERGO & others Rear Sling Plate | CQD | CQD | CQD Upper Receiver | Mil-spec forged M4 profile | Mil-spec forged M4 profile | Mil-spec forged M4 profile Barrel | 10.3" | 10.3" | 10.3" Rail | KAC RIS | KAC RAS | DD Mk18 RIS II (FDE) Rear BUIS | LMT Fixed | LMT Fixed, MATECH, & others | MATECH, KAC 300m, & others Front Sight | A2 FSB | A2 FSB | KAC 99051 BUIS (Taupe) Front Sling Attachment | FSB Sling Swivel | FSB Sling Swivel | CQD Muzzle Device | KAC M4QD | KAC M4QD | SureFire FH-556-RC Supressor | None | KAC QDSS NT4 | SureFire SOCOM556-RC (FDE) LAM | None | PEQ-2 | LA-5 Weaponlight | SureFire M962 | SureFire M952, M962 | Insight M3X (Tan), Insight WMX200 (Bronze) Optic | Aimpoint Comp M2 in Wilcox Mount | Aimpoint Comp M2 in QRP Mount, ACOG | EOTech 553 (Tan), EOTech EXPS3-0 (Tan), ELCAN 1-4x (FDE) ---------- Link to previous threads Previous Mk 18 / CQBR Thread Part I Previous Mk 18 / CQBR Thread Part II |

Not 100% sure, but there have been various reasons given for it by ADCO when the subject came up. Variables in factory barrel length I believe were mentioned, and whether you measured from the muzzle back or from the chamber/bolt face forward. I can't honestly say if that's a viable reason, or if it's just more a matter of them having a lot of work and not always being super detail oriented. The responses from ADCO have often given me the impression it's more of the latter than the former, saying things like, "Only someone taking Instagram pictures is going to care whether it's 10.3 or 10.5." I'm paraphrasing from memory, but those sorts of comments don't give the overall impression of a shop deeply concerned with details. Yeah, definitely. Part of the reason I prefer factory DD 10.3 barrels even if a chopped Colt would be more accurate. I've seen quite a number of chopped barrels where the shoulder didn't match the RIS II; clearly they were more like 10.4 or 10.5, and that would really bother me. While it's certainly not something I would want in any case, I could live with it a bit more on a Mod 0/CQBR Block I. On a Block 2 it just stands out like a sore thumb when the shoulder isn't even with the rail. ETA: I guess you could say the same about an incorrect barrel length sticking out on a Mod 0 because of the bayonet lug, but until I replace the 10.5 on my Mod 0 I like to pretend it's really not that bad, lol. As far as I know those specs are completely accurate. @Pezboytate would have to chime in with exactly the source, but they should be correct.

I know Adco has said to be very precise with what you want and to mark where you want cut, because otherwise, they'll get it close, within the tolerances that you specified. But to me, and likely most people here, the difference between 10.3 and 10.5 is pass/fail. Has this schematic been vetted for accuracy? If so, will be really helpful.

As far as I know those specs are completely accurate. @Pezboytate would have to chime in with exactly the source, but they should be correct. If you cut a barrel to exactly 10.3" with a .63" thread length, it will be too short. Crane cut down barrels are about 10.35" with a .60" thread length. Colt 10.3" barrels are about 10.38" with a .63" thread length. The problem is that ADCO and others don't know this and they probably don't care. |

All my replacement barrels that we have received from Crane for rebuilds have been Crane cut down Colt Govt profile 14.5" barrels. Haven't received any in a year however and the last few were new FN SOCOM profile 10.3". On leave right now so won't be able to measure for a few weeks.

I'm about to finish the Mod 0 and planned on the classic look with LMT rear sight Comp M2 with a Wilson mount. However, I have trouble with Aimpoints. The dot looks like a blob. I was thinking of a TA01NSN for the Mod 0 with a Matech rear sight. Thoughts or alternatives? Thanks

The MK18. Finally took the plunge. Hopefully the 4-Prong and Colt building block will stone for my pistol brace sins.
Haven’t had a chance to shoot it yet, but I’m in love with this build. Attached File |

From this I would have to say that there were either 10.5" barrels fielded or that none of the original Crane cut barrels were fielded.

I'm not 100% sure if new URGs come with cut downs or factory barrels, but Crane cut barrels are definitely still being supplied for replacements. Either way, you'd have to be cloning something very specific and very early to get away with a 10.5" being acceptable. View Quote View All Quotes View All Quotes Originally Posted By krdt:

I have tried searching high and low for some rough numbers here for a comparison I'm doing but strangely found nothing. So, could a couple of you chime in with your rough unloaded weights of your Mk18 CQBR rifles that are fully outfitted with optics, IR laser, suppressor, etc.? I realize there are an infinite number of variables here, but I'm looking for a rough approximation. Thanks!
