No plans to offer thermal fit, I don't think it's necessary. Once the barrel nut is torqued to spec, there is no movement. An accurate barrel will shoot sub MOA with our upper without thermal fit. An average barrel with thermal fit upper can't.
URF v2 is now out of production, we've moved to v3. |

Anyone use the new MCF-A rail covers yet? I have had plenty of railscales G10 in the past. Was going to go with the FCD version (MCF) this time around. They are discontinued now and they transitioned to an aluminum version, the MCF-A. Just never had the thought of using aluminum as a rail cover on an aluminum handguard. I need 6 and its a bit pricey to splurge before knowing what I am in for.

Wasn't one of the features of the G10 scales to protect your hands from the heat of the rail/barrel? |

View Quote Kind of why I want first hand experience. They have a whole heat diagram showing how the new aluminum design is actually better for heat mitigation vs the G10 on their website. But was hoping to hear first hand knowledge. |

MCF-A has performed better than both G10 and polymer covers. At best, we were hoping to see equal performance, we were happy to see it's done better than both.
The numbers don't lie. At first glance, aluminum cover on aluminum handguard doesn't seem to make sense. MCF-A isn't the handguard itself, the large surface area is partially responsible for it. |

I haven’t had a chance to shoot it yet, I just got the barrel back from having the gas block pinned, and the FH pinned and welded. |

You guys have the new muzzle devicd timing thingy right? Did I miss the discussion on that?
|
|
|
NVTS? It's on our site, as well as Big Tex Ordnance, Primary Arms and Revival Defense now

|

How does it work?
|
|
|
I can't link to our site, it's on the page, you dial in the amount of timing you need.
Place NVTS and your muzzle device on the barrel, hand tighten. Based on where your 12 o'clock lands (for example, the top center port lands at 9 o'clock, it should be at 12 o'clock) after determining the amount of timing required to time it (in this case, you're at 9 o'clock, you need to be at 12 o'clock) separate the NVTS disc from its base, add 3 tick marks (3 hours), plus 1 tick mark for torqueing. Put NVTS and the muzzle device back on the barrel, and torque to 25 ft lb +/- 5. Here's the video: ![]() NVTS instructions |

Slick. Thanks dude

@ Duffy
i'm assuming the NVTS won't have any effect suppressor alignment and can be used for suppressor mounts correct. |

Suppressor compatibility is what it's made for

NVTS in 5/8 x 24 any time soon???

|

That's pretty badass. More effective than shims? No. Still a great idea.
|
|
|
It takes about 3 to 4 minutes at most to figure out how much timing you need, dial in the amount required, and torque the muzzle device on with Rocksett. As far as shims and washers go, quality shims and washers do the same thing, the difference is how efficiently and quickly timing can be done with NVTS

Has anyone tried the ACF 308 with a newer MEGA MATEN? I just purchased one, and it seems the fence hits the back of the top rail just before the latch can catch. The MATEN is supposed to be SR25 compatible, which would lead me to believe the ACF should work.
Is this a known incompatibility? Should I try a different ACF? I don't feel like grinding anything to get it to fit. |
|
|
I've seen this with 308 uppers before, the pocket for the CH latch differs in location, size and depth, all of these are in the M16 TDP, but few large frame ARs use the same specs.
Relieve this area inside the latch/hook, the latch isn't engaging the wall in the CH latch pocket. 2 strokes with a file will fix it. ![]() |
|
|
It's a bit difficult to tell, but it seems like this may need a bit more than a couple of strokes of the file.
![]() Do you think I'd still be GTG? |
|
|
Yep, more strokes with a file than my MARS-H required. The lack of standards manufacturers adhere to is the reason we don't like to do a lot of large frame AR developments, the take down and pivot pins are different between SR25/KAC and LR308 patterns, and Armalite AR10-A's pivot pin is also different.
|
|
|
Thanks for the prompt help. I'll keep my fingers crossed for this. I knew putting a LFAR together would be a bit of a crapshoot. I wonder, too, if the way MEGA / ZEV finishes their receivers causes an issue, since they're always so tight.

I think it's a great idea. Your ability to find the small stuff and solve it is impressive. Combine that with customer service that's second to none one and that's why you get my money |

NVTS is a Swiss CNC designed and made product, we assisted with the ergonomics and user manual and video, and happen to be the first to carry and distribute it. There will be other names you recognize that offer it soon

The lever and the plate are now one and the same, it's the same mechanism Norgon uses. EMR-A v2 address some of the issues the original Norgon has by having a slightly longer lever with more surface area and much better traction.

They're in production now. Since we make all the parts from solids, it'll take at least 1.5 months to make a small quantity, ETA is October.

![]() original build plan was getting a little heavy for the intended purpose so i changed things up a bit. Need to get the muzzle device installed and modify the Reptilia 12:00 RRM/SRO mount a little then installed but this thing is finally done I think. Thanks FCD team @duffy |

Safariland holsters are great, the external ASC spring housing is about the only thing that needs a little loving attention.
The plastic ALS cap can break while doing ground shooting drills, and happen when the user is struggling or fighting with someone on the ground. ALS is machined from 6061 aluminum, and its wall is 57% thicker. After months of testing where the SWAT user dropped it, fought with it installed on his duty holster, generally abused it beyond the normal level of use the holster would see, all it got was a few scratches (prototype, in the white) on it. This was a request from an agency couple of years ago, we finally got it made, with assistance and input from Ghostmen Designs. We didn't laser engrave our or Ghostmen's logo on ASC, as it's primarily made for LE and MIL users and however small, the logos stand out too much, so ASC is discreet but if you know what you're looking at, ASC is shaped slightly different from the factory plastic housing, it's more square and doesn't taper on the bottom. ![]() |

I’m sure you could come up with something ever better though. I’m going to pick up an ASC. Always thought the plastic piece on the outer was asking to get cracked. Is the installation pretty easy with replacing the spring? Thanks! |
