Nice Selection, what do you think about the ACT Trigger? Everyone keeps asking me why I just don't go with QMS triggers. That the ACT is just $20 more for the coating and feels exactly the same when pulling the trigger. Every ACT trigger in my opinion has pulled smoother and more consistently than any QMS I've had. Is that your experience as well?

[UWone77]

I have 4 or 5 that I "spared no expense on" but just because you buy the best and most expensive, doesn't give you the gun you want for what you're going to use it for.

If there is any Manufacturers reading this, quit laser etching. Nothing is uglier than white laser etching on a black rifle. Now I've got to donate more money to coat my parts. Nobody cares to see the logos, except maybe Noveske's iron X, God rest John's soul. I often refer to my lower as a pre-death. If this truly was my dream build it would be full auto.

Actually I have no idea as I've never used either one. I just picked the more expensive of the two. [BD]

Rob, I fully expected a more expensive is not better post from you. Along with a get a Colt 6720 or 6933 speech :)

Well, the assignment was "unlimited funds", so if you think about it I should have really gone with something silly like the super three gun... :P



Rob have you had the chance to use the keymod system? I'd like to know what you think about it.
I have not. At one point I had both the Noveske and thenCenturion in my shopping cart at Rainier but they were out of the Noveske sling adapter at the time so I canceled the order. [BD]. The big thing I'm waiting for is someone to offer a VFG that doesn't require a rail section to attach and that is sturdy enough to use for the kinds of abuse it will take in a VTAC class.

[Wondering Beard]

What kind of abuse is heaped upon a VFG at a VTAC class?

[Army Chief]

I've got an NRW SBR upper in .300 BLK with the Keymod system that I've been getting ready to put into the mix, so while I can't report a lot of practical use as yet, I can address basic configuration and static impressions.

A couple of years ago, when we all seemed to have the collective epiphany that heavy guns suck, and quality rails aren't necessarily the one-size-fits-all solution that we had long imagined them to be, we began to see the emergence of a number of new "tube" type fore-ends. It didn't seem to take particularly long for folks to realize that the trim lines, lighter weight and smooth contours of these minimalist units had some real potential. The problem with them was that, if you still wanted to mount a light, QD socket or some sort of handstop/VFG, you were probably going to have to deal with some kind of proprietary bolt-on, piece of rail or some other improvised solution for attachment. The tubes were great, but getting them configured was sort of a head-scratcher because nothing was standardized, and they all seemed to have different slots, cutouts and reliefs.

Pretty obvious problem, really. What was needed was some standardization ... and that really is what got us to the Keymod. Standard slot configurations, standard interface, a clearly-defined standard for third-party mounts. This is all review, of course, but there is some value in repeating it, because it helps you understand why the Keymod is such an adaptive, useful and worthwhile component. You get a very svelte tubular profile, significant reduction in mass and weight, smooth contours where you need them, and mounting points wherever you want them. Two fasteners (usually), and you're in business. Don't like where that sits? Move it up or over or back an inch, and try it again. It's the best of both worlds.

Sure, we did all of the same stuff with the rail systems that we already had, but we you compare the two, you start to marvel at what we have been willing to put up with in terms of their blockiness, sharp edges and unnecessary mass -- just to get a few inches of railspace. Nobody is saying that a good rail has become obsolete, but depending upon your purpose for the gun, especially if you are trying to get full-capability from a small, lightweight and fast-handling package, the Keymod is a pretty elegant answer. More to the point, the entire rationale for it is to make it easier for everyone in the industry to produce components and hardware that will work just as well on a Keymod system from Noveske as they will on a system from Centurion or anyone else.

Bottom line? Keymod takes the somewhat unrealized potential of the tube fore-end to the next level, offers Erector-set-like flexibility, a common attachment method (open-source to all) and surprisingly robust connections. I've still got some work to do before I can lay claim to any special wisdom as a Keymod oracle, mind you, but the system makes good sense, is well-designed and is being fielded by the right people. It remains to be seen how foks will choose to integrate it, but my feeling is that we are looking at something more than just the next passing industry trend.

Postscript: here is where the rest of that particular SBR stands configuration-wise, since it has been built more or less with the thread's opening premise in mind:

Upper Receiver: NRW/VLTOR MUR
Barrel: NRW .300 BLK 8.2 (SS)
Muzzle Device: AAC 51T
Bolt Carrier Group: NRW
Charging Handle: RA Raptor
Lower Receiver: ATXS AX556 (w/NRW QD endplate)
Trigger: WC TTU
Selector: BAD ASS 90
Pistol Grip: Magpul K
Stock: Magpul STR
Sling: BFG VCAS
Iron Sights: NA
Optic: NF NXS C 1-4x (FC-1)
Additional Accessories: NRW Keymod (w/NRW covers, rails), SF M300A, chopped KAC VFG, AAC 762 SDN-6

Thanks for the thought out explanation Army Chief. I'm just waiting for people to put the system through its paces before I jump aboard.

What kind of abuse is heaped upon a VFG at a VTAC class?

Noting particularly unique, although with the number of people I see post "I am quit of VFGs" I always think "you probably haven't taken a VTAC class. The first picture in the link below gives you a sense of how much use Kyle has you wringing out of the VFG. In the shooting I do I'm constantly slamming it into things, hooking it onto things (including my left wrist when shooting under things), etc. After spending some time with my "back to basics" BCM Dissipator the VFG was one thing I couldn't do without.

Without having spent any time with it, I don't have a good sense as to whether a Keymod-attached VFG would hold up to the abuse.

Upper Receiver:
Barrel: Satern SS Fluted 18" 6.5 Grendel Barrel Bolt set
Muzzle Device:
Bolt Carrier Group: BCM
Charging Handle: RA Raptor
Lower Receiver:
Trigger: Geissele SST
Selector: BAD-ASS
Pistol Grip: Magpul MOE

The more I've been playing with the two carbines that I have, the more I narrow down what I think the most well-rounded rifle for my uses would be. I've got a Centurion CHF recce, and a BCM LW KISS rifle that have been fantastic. I see the roles they fill being pretty much complete. What I now envision a perfect carbine for almost any practical use, I see a weapon with an accurate barrel that is capable out to 200-300 yards, but ideally going to perform within 75-100. This is just based on historical uses of combat weapons in both war and self defense.

Given unlimited funds, I think the ideal carbine for my uses would look something like this:

Upper Receiver: Innovative Arms W.A.R. - This allows me to run a longer rail over the gas block but still be able to easily switch between suppressed and unsuppressed fire

Barrel: Noveske stainless 11.5 or maybe 12.5 Crusader - Since the vast majority of any shooting is within 100 yards, I'd rather save the weight and have a handier weapon

Muzzle Device: SilencerCo Saker 5.56 and trifecta mount

Bolt Carrier Group: BCM Auto

Rail: BCM Keymod (11")

Charging Handle: Rainier Raptor



Lower Receiver: Seekins SP223 Ambi

Trigger: Geissele SD-E - I've got 2 mil spec triggers, an ACT, SSA, SSA-E, and SD-E. The SD-E is my favorite trigger by far.

Selector: BAD-ASS ST with Crank and Stubby

Pistol Grip: BCM Gunfighter

Stock: A5 tube/buffer with ACS-L stock (Runner up would be UBR just for sheer stability)

Sling: VCAS

Iron Sights: Troy

Optic: Trijicon VCOG - with nods to TA-33 and SRS as well, any of the three would work for me. I like the option of magnification for target ID purposes, but also like speed of 1x
