Got to see some of the regional guns at a training event earlier in the week.  Wanted to take some pics but didn’t want to look like an ass.  All were rocking the Gen 2 rails with the longer picatinny rail on the bottom.  All were using MBUS Pro BUIS, had padded VTAC slings and the Ergo pistol grip in black both with the beaver tail and without.  They had some type of enhanced trigger guard (Magpul?).  Lowers were a mixed bag, most were Colt.  One appeared to have had been spray painted at some point and was marked M4A1.  Optics were all either Aimpoint Micro T/H 1/2 on DD mounts or had some variation of the SIG Romeo 4.  They appeared to be 4Ms but had the mount from the newer 4T.  They weren’t 4T’s as they had no solar panel.  All were using tan ATPIALs and were equipped with OSS/Huxwrx cans with the OSS flash hider.  All had black Geissele government charging handles.  Foregrip accessories were all different, seemed to be users choice.  Saw BCM KAGs, BCM VFGs, Magpul RVG, Magpul AFG, and one was using the FAB defense afg.  Lights were mostly black Surefire Mini Scouts, however one was still using the Inforce WML.

Following up, I received the rail earlier this week, and it did include the QD inserts.  One thing I didn't realize was the insert color isn't a shiny brass like past pictures made me think, but rather more of a copper.  Looks more subdued and definitely better in person.  $280 was too good a deal to pass up, so I'll be keeping this for a future near-clone build.

I think a gen 2, but positive id and accurate shots isn’t a bad thing to have around. with modern lpvo’s I find it pretty close to shoot with a lpvo vs red dot.


Razors aren’t uncommon among HRT

There were only 2, maybe 3 total of these that hit the open market years ago and were not available to the public. I bought one and another early poster in this thread got one. All came from the same individual that did consulting work with Geissele. You and I have traded messages on this before.

I used a Geissele Super Gas block that I had port restricted by Black River Tactical. I’m not sure they’re providing that service anymore, I think they’re just selling their restricted gas tubes. Regardless, I don’t think I would ever do business with them again. The product is nice, but the turnaround time was awful, they lost track of my gas block for a while, and communication from them was very poor.

I have an insert from Black River Tactical that I had John Thomas of Retro Arms Works install on a Geissele carbon steel gas block. It’s on my OD Mk4 Fed gun and insert is set up for suppressed subsonic 300 Blk. But IIRC I’d done all this in late 2018.

Thanks for the tips guys.

JLAudio - Thanks for the update. I was wondering if more of these popped up on the market. Still willing to buy if you ever change your mind.

Does the FBI HRT rifle still use the port restricted gas block? Wasnt this set up for suppressed only? I see a lot of the rifles now without suppresors.

It accommodates the AFG-2 with the front of the AFG nearly flush with the end of the rail.

Second pic in the OP shows it pretty well.

Thanks, that looks pretty good. Especially on SBRs, I tend to have a pretty far forward grip, so that will probably work quite well.

I’ve been terribly procrastinating, but I think I’ll finally be putting together my Individual Agent clone soon. I finally ordered the last couple things I needed, an Aimpoint T2 and my Troy rear sight.

I believe the only differences are:
1. MK4 Federal is a 10” length vs 9.3”/9.5”/10.5” for MK4
2. MK4 Federal has a longer picatinny rail section at the 6 O’clock position (at least the newer versions)

I’m curious what buffer everyone is running? My upper is being assembled right now and my lower currently has an H buffer. My Geissele Super Gas Block has the BRT port restriction to bring it down to the correct .67 gas port size. If I’m going to be running unsuppressed, do you guys think the H buffer will be good or should I think about picking up an H2 buffer?

I’ll be running brass cased ammo only, mostly M193 but my duty ammo is Hornady TAP.

I'm running a current production 6933 barrel with .074 gas port, unrestricted/standard Geissele Super Gas Block, Colt H buffer, and Colt carbine spring. This is how Colt ships the 6933 (this rifle was originally a 6933) and is how the regional SWAT rifles are configured. It runs perfect unsuppressed though I may go with an H2 with a suppressor.

If your rifle is going to be used as a patrol rifle I would discourage using a port restricted block. It's not needed and the gas ports used on Colt barrels when paired with an H or H2 buffer are good for a variety of duty and training ammunition without being too much or too little.

ETA: Updated pic of my rifle

Almost clone correct for regional SWAT. Started as a factory 6933 SBR, sold the original skinny FSB barrel and BCG off and kept the upper receiver and charging handle. I've got a Surefire SOCOM RC2 on the way and it seems more fitting than my Dead Air Sandman S. The Spuhr HRT mount has been seen on regional guns but a DD mount would be more correct. I just don't care for the rock and lock DD mount.
