What's the general consensus on lower receivers for the CQBR Block II? Is it Colt or bust? I'm trying to get the Form 1 started out in front for my build, but damn I'm seeing stripped M4A1 lowers at $600 bucks! I mean if thats the only clone correct route then I guess its put up or shut up, but I figured I'd ask the gurus' opinion first.

An 80% lower may be the visually closest to an actually M4A1 lower. If you read through this thread, you'll find that opinions are mixed. Technically speaking, a CQBR is just an upper receiver so you can use whatever lower you want. Good luck finding a consensus here...we're all crazy ETA: I suppose you could also use an FN M4 lower...although it might trigger some people here. |

Oh you guys are way more inviting over here as opposed to the MK12 thread. Lowers will get you banished from the clone crowd over there. I'm thinking about just keeping an eye out of a colt m4 carbine lower and rolling with that. If I have to drop a mint of the surefire flash hider I may opt for a cheaper iteration, but I'll cross that bridge when I get there. As far as that flash hider is concerned, does anyone have any advice on acquiring that? I've got a thread on the EE, but outside of that I peeped one on gunbroker, but its sitting at $220 and it appears as if the previous owner beat it up pretty good trying to get it off the barrel.

Just got my hands on a stripped colt upper.
Do I rip apart my factory DD upper and replace it with the colt one just to be more correct. Should I replace the pinned gas block with the crane style while I’m at it? Is it worth my time removing all the Allen screws? Help. |

I was just lucky enough to snatch up the surefire 4 prong this evening and the gentleman was telling me that the knights armament lower receiver was also in the wild as well. Anyone ever heard of that? I’m sure the issues (if they were) is actually a full auto version, but I’m sure the knights lower is a much nicer receiver.

As lowers wear out or get destroyed and replaced, FN lower may get used. FNs have been issued to the Support Battalions in Group also. CD |

Good tip though, I need to make it a habit to remove the suppressor after use. Though I'm sure old dirty ammo, high humidity that day and putting it up wet didn't help much either. |

Yes, they are dimpled on current production. As far as correctness, we know at least 1,407 DD 10.3" barrel/bolt combos were shipped to Crane. I think it's fairly safe to assume those replacements were put to use somewhere, and therefore DD barrels have been used on issued guns. For a generic Mk18/CQBR clone, I'd say that's good enough. I use DD barrels on both my Block II CQBRs--although, to be fair, I was using them before I even knew about the Crane acquisition, lol. |

Guys, quick questions here:
On the Form 1, Question 4D. It says "Model (As marked on firearm). What is the correct answer for this box since AR15 is NOT marked on the Colt gov't property lower i'm using? Next question on the Form 1 is Question 4F: What is the OAL of a SBR with LMT SOPMOD stock, milspec buffer tube, and 10.3" Colt barrel without the muzzle device attached? I'm seeing a bunch of different answers from 27.4" all the way to 29.5" and different answers like add barrel length plus 19" and i don't know what to use. Last question on Form 1 is Question 4H: It says additional Description. Do you guys leave this blank or do you put your Trust name, City & State? I'm filling this out on Eforms so please keep that in mind if it means anything. Thanks. |
