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

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.

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:

It appears the only "in the wild" clone correct grips are A2 or Hogue. Not bad options but, without combing through 60+ pages, have we seen individual used Magpul or other variants?

Also: Magpul AFG2 seems to be pretty standard. Have we actually seen any other AFG or VFG on issued rifles? Either HRT, Regional, or Individual Officer? Magpul VFG, BCM stubby, KAC broomstick? Just curious.

As previously mentioned, plenty of Ergo grips in circulation. AFG1 seems to be more common than AFG2, but both are common. The Grip Pod is also seen from time to time... This pic is interesting as it also shows a BE Meyers muzzle device instead of the SF suppressor mounts and A2s more frequently seen.

I did the bombproof install. Used a drill press, was really surprised how hard the barrel metal was. Buy a good bit and use some oil, very easy.

Currently, Gunbroker has listings for over $600.  A few months ago I bought a gray Gen 1 here in the EE for $385 and right after an OD Gen 2 popped up in a local Facebook group for $300...so I ended up with two Federal rails and one pissed wife

If you do try an H3, please report back. I am interested to see if that would be a better match for the LE6933.

The gas tube measurement fits with BRT's recommendation to use their .065 gas block insert on the Colt 11.5" barrel, which is supposed to equate to a .067 port size (one size up from the insert) once installed. I posted about my gas block here after I got it back.

You might want to look into the brt gas tube instead of the H3 to help reduce gas.

Is this the OD Hogue you are looking for?  Compared to a GI OD Blasting Cap Box on left, Foliage Green 504 Fastex on right, on top of a GI OG507 Patrol Cover (PC or Patrol Cap- Cap, Field, Cotton, M1951)   I don't have a particular attachment to it, I just liked the feel of the rubber coating, had it on a C7 clone.  Would horse trade it for an OD rubber MagPul Grip.

I believe it's been known since this topic started that HRT was switching to the Geissele Mk4, but photos didn't show up here until 10 or 15 pages back. I think the Mk4 adoption was FBI-wide from the beginning, but I'm not that knowledgeable about the history.

3ACR_Scout thanks for the reply, so a black gen 1 05-430 would be correct with the Spuhr mount and T-2. A black government charging handle? or standard milspec. I have an od ctr stock but that can be changed easily enough as can the pistol grip. As for the buffer tube the anodized od green does look great with the od rail but again if its not correct, why.  Have a few other pieces that may or may not work.

Yes, all the FBI variants use different colors of the 10" Mk4 Federal rail. I'm not sure about suppressors. They've come up a couple times, but since they seem to be used only by HRT members, and photos of them are hard to come by, I don't recall what's been posted about them. I believe they use Surefire adapters and suppressors, but that's about all I remember.

Black is used by regular field agents, and they don't use the Spuhr mounts, from what I've seen here. The FBI approved the Sig Romeo 4 for field agents, along with Aimpoint H1, H2, T1, and T2 models (here's a reference article). Non-HRT (SWAT and field agents) use Daniel Defense Aimpoint micro mounts.

The colors and associated accessory variations are broken down in the first post. ARogueNinja, the original author of this topic, was good enough to paste the info in there that I compiled from various people in this thread, including a couple FBI agents. You have to expand the quote under my username at the bottom of the original post to see this list:

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

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

You know looking back I can't tell what color this HRT rails are, the pics are too blurry. Are there clear ones?

It's too bad if it is DDC because I love the OD, who knows.

Several FBI members have confirmed here that HRT is using the DDC rail, but pictures are scarce. I'm not sure which page in this topic had the photos of HRT members with Mk4 rails. I've looked for them a couple times but got tired of paging through this long topic.
