[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 |

So, I got the SBA3 installed and had a little time to mess around with it. The thing I noticed immediately was the weight difference: the SBA3 is significantly lighter than the SBM4. The SBM4 with APF tube comes in at a fairly hefty 17 1/8oz, while the SBA3 with the included tube is 11oz even. On the one hand, the lighter weight is nice and I immediately noticed the difference in the overall weight of the weapon; on the other hand, the extra weight of the SBM4 does help to balance the front-heavy CQBR a little better. If I were running a suppressor, I think I'd probably go with the SBM4. Another significant difference is that the SBA3 is made out of something more like a hard plastic rather than the usual rubber on other SB braces. The "flaps" are the only part that are slightly rubbery, and even there the rubber is much harder than on an SBM4. The harder plastic/rubber seems like it would hold paint pretty well, so you'd have a viable option if you want to rattle can it - which I definitely like. Very good chance this will go over to the Mod 0 and get a paint job after my stamp comes in. Between the two, the SBM4 still has a slightly better cheek weld IMO and has a bit more of a solid and beefy feel to it. Of course, that comes at the expense of weight. One other feature on the SBA3 that I definitely do like is that it can't rotate on the tube. While I never had too much of a problem with the SBM4 rotating, during the heat of the summer it did happen occasionally. Also, sorta goes without saying that having adjustability is a big plus - the option to collapse it down when inside vehicles was a big part of why I wanted one to begin with. Overall, it seems like a pretty solid little brace with some very useful features. I'm definitely looking forward to giving it a try this weekend. And now the pictures :D.

The plastic seems a little thin and brittle for such a hi ware area. I'm not sure if they re-designed the latch system to avoid looking like a stock or not, but I definitely would've used a different or thicker plastic for the lever/ latch. I'm curious to see if it's been an issue yet. |

The commercial colt carbines come with that hot dog safety that has a huge hot dog on it that extends into the middle of the selector and just looks weird. View Quote As far as safeties, I thought tick vs. no tick referred to the presences of a hashmark on the support side of the lever (to point to safe or fire, etc.). The current commercial ones are blank on the support side. Second, is there a non-commercial ambi safety? Because the hot dog piece is present on the ambi safety and looks no different. I agree with you that it's ugly, but I guess I didn't realize there was a military version that was not so gargantuan. To me that top one looks like an old design. Is it fielded and I've just managed to not notice it in any pictures? |

I think the ambi was more of a later thing. Issued for either would be a std colt safety. Cqd is more at home on a cqbr than the iconic mod 0 which used the side sling. Or sell the Wilcox and get the cheaper qrp. I don't have any side by side pics, but there are like 3 or 4 qrp mounts out there. You want one of the earliest two that had the protruding tension knob that stuck out like an inch. here is the earliest one with the flat base and spacer to bring it to lower 1/3.

From what I hear colt is having a issues with their anodizing that’s why some are getting odd shades of color.
I tried ordering a upper 2 weeks ago and that’s the reason I got for them being out of stock. |
