This thread will be dedicated to builds and discussions of the FBI clones and thanks to Geissele for listening to the masses and releasing the much coveted rail. Parts lists will be updated as we go. Please keep it on topic and post pictures of your builds and "in the wild" photos.
     Barrel: Colt 11.5" barrels & others since there was already a mix of stuff out there between the different offices, prior to the upgrade starting. Lower: Colt/ some older DOJ contract RRA lowers, among others. Grip: ERGO/ Hogue/ A2 Upper: Most of the uppers appear to be Colt marked. Rail: Troy and Geissele, seems like the main colors for the MK4 rail are Black and OD, unsure of the others. Flash hider: A2 flashhiders/ Surefire/ KAC NT4 Optics: Aimpoint H1/T1s & H2/T2s are approved, along with the Daniel Defense mounts. The Sig Romeo4 red dot was also approved and is being used by some other federal agencies too. Spuhr mounts for Aimpoints for HRT guns. EOTech EXPS 3 & G33 Magnifier Sights: Troy BUIS/ Magpul MBUS Laser: L3 AN/ PEQ 15 Stock: CTRs Sling: VTAC 2 points/ Magpul MS Light: WMLs/ Surefire Scout More info here: Industry Thread Originally Posted By mbpike: Originally Posted By GS5414: Alright homies. I'm going to drop some knowledge, and then ghost. Folks generally got a handle on the right parts. Right now, the FBI has stopped throwing out their T2s/Spuhr mounts because folks are starting to regret replacing them with the ROMEO RDS. Things aren't holding up to abuse and long life. Who knew. You'll see the Aimpoint make a comeback. Also, nobody in this thread has the right gas block. Geissele gas blocks are used on the FBI guns, but they are port restricted gas blocks, as in the ports aren't drilled all the way out. We used them in the USMC for some of the souped up M4s, at both 0.072" restricted for 14.5" guns (a bit too small), and 0.068" restricted for 10.3" guns. The FBI uses 0.067" restricted blocks. I think I have one of them stashed away that I never managed to use - might take a photo of it if I can find it. They do a good job keeping gas port erosion from affecting function of the guns as the barrels burn out. Keeps carrier speeds lower, recoil is a bit softer. They are not sold commercially, or even talked about for that matter. If you want the same function, take a G block and thread it for a BRT Micro Tune 0.067" port insert. I'm out. S/F Lets get this added to the OP. Originally Posted By elucidate: Not a clone. Large regional SWAT. Skinny commando barrel. Originally Posted By elucidate: Indeed. When I said 'not a clone' by that I meant it's a picture of a real upper, sat on a desk in a large regional FBI training facility, not something I made at home. Originally Posted By 3ACR_Scout: Originally Posted By AZgunner: I haven't decided if I'm doing the clone correct green rail, or if I'll do the same setup but in all black. It depends on where I'm at in a few months. If I need to give my current rifle back and use the FBI clone on duty, I need to do it in black, as only all black color schemes are currently authorized. A black rifle can be completely clone correct, it would just represent a regular agent's rifle, not HRT or Regional SWAT. This thread started as a result of the interest in the green Geissele Mk4 handguards that showed up on Regional SWAT rifles, but all four Geissele colors are in use by the FBI. People are just (understandably) a bit fixated on the green ones because they look great. That's led to what a lot of people are doing, which is combining the features of the HRT and SWAT rifles into a mixed clone (SWAT green handguard and CTR stock, HRT heavy barrel, and Spuhr HRT Aimpoint mount). I think it would be great if @ARogueNinja could update the original post to reflect the four FBI variants that are out there (these details are incomplete and could be a little off): HRT: DDC Mk4 handguard, 11.5" Colt HRT heavy barrel, Aimpoint T-2 on Spuhr mount (not sure about the stock), black or FDE(?) CTR or Colt stock Regional SWAT: OD Green Mk4 handguard, 11.5" Colt LE6933 government profile barrel, Aimpoint T-2 on Daniel Defense mount, OD green CTR or Colt stock Vehicle Teams: Grey Mk4 handguard, 11.5" Colt LE6933 government profile barrel, Sig Romeo, FAB Defense PTK AFG, Maxim Defense collapsible stock https://www.ar15.com/media/mediaFiles/1182/green___grey_M4_carbines_jpg-1584398.JPG Field Agent: Black Mk4 handguard, 11.5" Colt LE6933 government profile barrel, Aimpoint T-2 on Daniel Defense mount or Sig Romeo, black CTR or Colt stock I think this is a grey Mk4 issued to hrt4me but is (I believe) representative of the standard agent rifle configuration. I don't recall seeing any photos in this thread of a regular agent's carbine: https://i.imgur.com/A6UVttH.jpg |

IN ON 1!!!
I ordered 4 of the Federal rails. a DDC, Gray, 2 x ODG. The DDC is going on my current gun to replace my MK4 9.5", the Gray is going on a 12.5" project I'm going to start soon, and well the ODG rails (at least 1 of them) is going to be a very very very slowly built FBI Regional Gun. ETA: Fucking missed page 1. |

Any of these guys ever running 14.5" barrels? I ordered one of the MK16 rails and charging handles in OD Green. I don't live in a state where I can have SBRs, so if I clone, it's gotta be 14.5".

Surefire rails with Inforce WMLs, PEQ-2s, LMT rear sight, Eotech (unsure what model, but looked like 552s). Guns were camo spray-painted in my AO. I'm also unsure of bbl profile, but they were the 11.5" barrels with FSP. SWAT guys had Colt full auto lowers, regular agents who did not have an MP5 in 9mm or 10mm had RRA ARs that were a true mixed bag in terms of setups. SWAT guys also had Springfield Professional 1911s, although must carried the G22s at the time (now replaced with 9mm guns). *ETA: another pic of current guns. https://i.imgur.com/9vvYnw7.png Quasi-pic of how they used to look, minus the 11.5" bbl https://i.imgur.com/PPASmnS.png The SWAT guns are full autos but they have the option of Geissele triggers. I was told some guys don’t want the Geissele because you lose the auto capability. My own work gun has 3 round burst and I would gladly swap that for an SSA but to each their own. There are still 1911 and G21 POW s around but for team stuff it is green 17 only. |

So for those doing this, just stripping off the FSB and set screwing the G block?
I hate having that stupid front pin hole exposed when the FSB is removed, almost as much as I hate relying solely on set screws on a non-dimpled barrel. Thinking of just shaving the FSB and calling it a day. |

Yeah maybe a mod can combine all the threads?
I'm in on the FBI clone build so I picked up a Mk4 rail. I might depart from the standard 5.56 and build this rifle in 6.5 Grendel. If you've been tracking; the 6.5 G with an 11" barrel has better ballistics than the 5.56 but hits like a 300 BLK that can go out to 800 meters. I think its a perfect round for an SBR and it should go perfect with the 10" G rail. Barrel will be from Alexander Arms as they've done a lot of the dev work on this round. We'll see how the parts collecting shapes up. |
