I got a couple of those with my last couple issues. They weave into MOLLE so you could have the light on your chest and they had magnets imbedded into them too. I never used them much, I preferred a good Princeton headlamp.

So does it improve anything being on the ACH itself or only for mounting elsewhere? Cause this light is strictly staying on the ACH for me since i'm not in a combat zone, until ISIS invades

No, that extra mount thing is only for attaching it to your plate carrier/chest rig. Or to something made of steel (interior of most MRAPs)

The swing mount allows us lefties to mount it on the other side of the helmet so it doesn't interfere with the stock.

I'd call that a great start. If you have money burning a hole in your pocket, you might want to pick up a KAC NT4 FH, and a teardrop forward assist (not a requirement, but there are a good number of them out in the wild). Also, consider upgrading the extractor bits and pieces (per NSW documentation - Page 12).

Unless they changed how they mount since I was issued them, it just clamps to the rim of the helmet. No drilling required and you can adjust it fore and aft to accommodate your needs.

What happened with the "H" buffer? Still too heavy? What setting on the gas block did you use? Were you running the can?

Thunder, I haven't shot it yet with the "H". Christmas day I was shooting Federal .223 bulk, not 5.56, with the H2 buffer I have plenty of 193, but did not have it with me that day. With the Socom Rc on, it would not lock open on the last round with the port set on .048.  I was also having some trouble with the KAC 2 stage trigger, so I did not do a whole lot of shooting with the CQBR.
   Weather permitting, I will have it out tommorrow or Tuesday. I will take both .223 and 5.56 and test with and without the suppressor, on both port settings. I'll report back with the results.

Thunder.......shot it today, suppressed, with 5.56 and .223, with the "H" buffer. I had to drop down to a std. carbine buffer for it to lock back on an empty mag.  With the "H" everything was good EXCEPT it didn't lock back.  This was with it set on the .048 port. Very little difference in ejection pattern between "H" and "std"....not enough to say the empties were landing in a different spot, only difference being that it locked back on an empty mag with the STD. buffer.  I did not shoot any unsuppressed.  Take note that mine might bleed more than a factory Govnah, which may be the reason I had to drop all the way to a standard weight buffer.  
   It's smooth as silk though set on .048    Cases eject to 4:30-5.00 o'clock.

You may have a slight gas leak somewhere from the block to the carrier key, or gas block and barrel ports only partially aligned since you had to drop all the way down to a standard buffer. But as long as it locks back and functions right, fuck it.
Link Posted: 12/29/2014 8:33:11 PM EDT
[#21]

Milspec............yes, I do have a gas leak. I machined an adjustable gas block, very similer to the Govnah adj. block that is available. It has a slide plate between the barrel gas port and the gas tube "port". By design, it has to be a loose enough fit to allow the slide to slide back and forth, thus the gas leak. I don't know the tolerance between the slide and the block on the Govnah, but mine DOES bleed some gas. I've seen regular gas blcoks and gas tubes leak some gas, even when they are a very snug fit, so it is no surprise that my adjustable model leaks.
     I did notice when I got home and cleaned mine today that the "snubber" on the end of the buffer had come apart. It must be a junky buffer because the snubber was not made from Urethane like the Colt buffers have. I also now notice that the buffer does not have internal weights that slide a small amount. I pulled the buffer out of another SP1 carbine I have............all Colt............and the buffer has the weights in it that slide. I'll have to drop that buffer in the CQBR and make another trip to the range tommorrow to see if it functions differently with proper buffer.
  Also, you did notice that I say I am running a .048 gas port?  If I run the .070 gas port the carbine functions flawlessly with either 5.56 or .223 and with or without the can. With the can on, and the gas block set on .048 port, that is when it needs the std buffer weight to lock open on an empty mag.

I don't know the tolerance between the slide and the block on the Govnah, but mine DOES bleed some gas. I've seen regular gas blcoks and gas tubes leak some gas, even when they are a very snug fit, so it is no surprise that my adjustable model leaks.
     I did notice when I got home and cleaned mine today that the "snubber" on the end of the buffer had come apart. It must be a junky buffer because the snubber was not made from Urethane like the Colt buffers have. I also now notice that the buffer does not have internal weights that slide a small amount. I pulled the buffer out of another SP1 carbine I have............all Colt............and the buffer has the weights in it that slide. I'll have to drop that buffer in the CQBR and make another trip to the range tommorrow to see if it functions differently with proper buffer.

As for the buffer's bumper I think I probably know what the deali-o is. Through a trade I ended up with a carbine buffer that seemed to have a "harder/more brittle bumper on it. I think they're ebay-ish buffers. The thing fucking shattered when I threw it in a lower attatched to a BCM upper (overgassed from the factory) so i've been buying buffers from BCM ever since. The Colt buffer should be good to go too tho.

The artwork is free for all to use - I've thought about and explored many different options WRT getting them printed, both as vinyl stickers or actual MIL-STD compliant tags, but was never able to finish it up, but anyone who wants to is more than welcome to use the artwork to do so.  

The rectangular IUID graphic actually needs to be revised in the near future - at the time I was working with a composite of the square IUIDs, and other rectangular IUIDs found on M240B/Ls, etc. to generate the IUID graphic, as I did not have any good photographs or images of the rectangular IUID.  

The size of the data matrix relative to the text has to be tweaked slightly, as well as changing "MFR" to "CAGE."  

Also, FNMI M4 and M4A1s should probably be added as well.  

I'm guessing that older M4A1s that have been through TI and/or rebuild probably come out with TACOM IUIDs when they get them installed.  The P/N and S/N are the important pieces of information as far as the military supply system is concerned, the OEM MFR of the base component is largely irrelevant because it should all be "MIL-SPEC."  Factory new examples may or may not come with actual manufacturer's CAGEs on there - the square IUIDs are based on actual USGI M4 Carbine IUIDs, which did have Colt CAGEs in the MFR line.

What happened with the "H" buffer? Still too heavy? What setting on the gas block did you use? Were you running the can?

Thunder, I haven't shot it yet with the "H". Christmas day I was shooting Federal .223 bulk, not 5.56, with the H2 buffer I have plenty of 193, but did not have it with me that day. With the Socom Rc on, it would not lock open on the last round with the port set on .048.  I was also having some trouble with the KAC 2 stage trigger, so I did not do a whole lot of shooting with the CQBR.
   Weather permitting, I will have it out tommorrow or Tuesday. I will take both .223 and 5.56 and test with and without the suppressor, on both port settings. I'll report back with the results.


Thank you for the follow up! I'm installing a Govnah this week and will try it out this weekend. Based on your results, I think I'll bring an "H" buffer just in case. I'll be watching for your results.

Thank you for the follow up, I really appreciate it! Can't wait to try mine, I hope it's worth the added perceived weight. It might just be me, but when I pulled out of the packaging tonight, it seemed pretty heavy.

on the weight......mine went on at the same time as the can so it was so much heavier that couldn't tell what was what. I take the can off and I can't say that it is noticably heavier.

That's a Durango, but I'm interested in that question as well.

I just stuck my DD wrench side ways into a vise and clamped down on it a few times to close it back up.  Just like new!

Got some better (at least IMO) pictures of my SOPMOD kit and the CQBR with the X300U.  I've been trying to get my lighting figured out for indoor pictures but I still have a lot of tweaking to do.  This photography thing isn't easy.  





And lastly, my SOPMOD clone family.  The CQBSS will be making it's way over onto my upcoming .308 AR build and a TA01NSN will be going on the Phased Replacement clone.

Looking for some quick advice. I just got a Govnah and it comes with 2 different plates. .070/.049/.082 and .073/.052/.082. I typically run 55 gr 5.56 at the range and occasionally run M855. Should I play it safe and install the slightly larger plate, or do you guys think I am good-to-go with the one that's "to spec"? I don't want to mess around with trial and error if I don't have to. Thanks in advance!

ETA: Will the SOCOM RC create enough pressure to run it on .049?
