The above Rainer wishlist will run $583.68 without shipping (maybe less with LEO discount?). Only stuff that is not Ti are the KNS pins, rail, ejection door and saburtube.

Throw in a 10.3 MK18 barrel and a CMT upper that's what I am considering.

Opinions?

Looks interesting. What trigger? And why KNS pins at all? Are they lighter than standard pins?

Probably ALG or Spikes battle trigger (since I have one of each sitting around)

I put KNS pins on all my guns. Had a pin walk out on me once (OEM install, not mine) and I said f-that, never again.

That would be awesome. May as well get a lightweight gas block too.

I thought about it but I have a gas block already that is pretty light.

Definetly looks like a solid build for sure. What muzzle device and BCG? Some you have lying around? Those parts could be TI as well of course.

Keep in mind Rainier Arms has free shipping until June I believe... Devil on your shoulder, out.

Not a fan of the V7 dust cover, it lacks the bump that prevents it from opening up all the way so it gets in the way when you try to put your upper back on your lower, and it'll scratch the hell out of your lower if you're not careful.

So not an issue. Close dust cover, pair upper and lower. I run these.

As you know, the barrel, handguard, stock and optics are where it really matters, then you hit the point of diminshing returns pretty quickly. I did go with a V7 carbine tube and end plate on my lightweight build (paired with MFT minimalist stock).

But beyond that, the extra cost of some of those small parts just doesn't seem worth it. I'm not going to add up the extra cost and weight advantage for those small pieces, but I'm guessing that is in the ball park of an extra $150 to save less than 2 or 3 ounces of weight. From a practical point of view, it's the equivalent of picking up a few more Pandora charms - you do it because you want to.

Nice yakuza blaster.

Muzzle device will be a gemtech bilug and a g5t

Just some ideas to consider:

The BCM KMR is still the lightest on the market by a decent margin ( V7 sells a titanium KMR barrel nut too ):
http://www.bravocompanyusa.com/BCM-KMR9-Free-Float-Handguard-p/bcm-kmr-9-556-blk.htm

I believe it's like 6oz with the BCM steel barrel nut vs. the SLR Ultra Lite at around 8-8.5 oz with barrel nut.

Titanium BCs can shave off a good 4oz+: http://www.stcroixtactical.com/products/sct-titanium-bolt-carrier-group-ar15-m16

Also, Faxon has some incredibly light barrels. They make the barrels for that Mag Tactical barrel:

Those are not scratches.. they are character marks. A beat up gun is a loved gun, it means it works and love to work it.

Expensive, but why not if it lights your fuse. I'd go with a Strike Industries Enhanced Ultimate dust cover - about the same weight and half the price.

Doin some more reading, found that the AP Rhino carbon fiber tube attaches to a standard GI nut (which v7 sells) and barely weighs anything. Comes in keymod or mlok.

Not tok shabby

I wonder if the tube from the battle arms OIP rifle is available.

For the handguard alone, this is true. However, the Midwest Industries hand guards come with 5 QD sockets. Adding even a single QD to the KMR pushes it close to the same weight as the MI, adding two pushes it over.

The point is, when comparing parts weights you have to consider the entire system. I once removed a DD M4 handguard from an SBR to install a Troy tube-style and found that by the time I added back a Pic rail to attach my VFG the "lighter" Troy actually added more wight to the gun.

Another lite handguards is the 2A Armament BL Rail, but it's only available in 7", 12" and 15". If you replace their titanium barrel nut with their aluminum one it reduces the weight by 0.65 oz., that would put their 7" version at 5 oz. with all hardware included. 7.45 oz. for the 12" version. But this is without a QD socket as Rob_S has stated.

I like your original idea with the SLR rail, personally I think the round tube rails are hideous.

Yeah, I don't know. the NSR is "round" without being round and its pretty cool, same with the MKR. The ALG I have is a very nice rail as well. Round might be the new square...

Could always get the Ti barrel nut and clamps for the KMR, made by V7.

Yeah and I hear that vocal fry is an "IN" thing to but I personally won't be riding that bandwagon either. :)

Ran across this the other day:

I think 4.5 lbs is as light as you're gonna get! I might build something like this one day. My favorite builds are always the lightweights ...

i have a 14.5" noveske upper with NSR and it's super light. Highly recommend.

I had an NSR, awesome handguard - though I didn't like the proprietary nut.

I saw that, Moxydave, not exactly what I want to build, but close.

I need to STOP reading articles like that, because I always want to follow suite and do an ultra light build...

I'm in the process of building a 14.5 Noveske Thunder Ranch clone... It should weight right at 6lbs finished.

I looked hard at the V7 stuff when I was selecting parts and they have quality no doubt. But the huge price increase just to shave an oz or two isn't worth it IMHO

I'm curious, for those pursuing the lightweight and ultralight guns, do you have a purpose in mind that would benefit from reduced weight or is this just a thing to do just because?

I assume you carry around a 20inch, m16 clone.

Since everything else is a just because type of build.

Right?

I like to keep my gear as light as possible while still retaining good functionality. I doubt I'll ever have a need to drag my rifle around with me but if I do, I'd rather have something lightweight. In that situation I would have no resupply, there would be no sustained firefights requiring a heavy barrel, etc. I do the same with my camping gear, my motorcycle gear, my clothing, etc.

Also I just think it's neat. I don't mind paying more for something if it makes me happy. Any time someone shoots with me they pick up my lightweight rifle and go "damn! this is nice!".

I did a test in Gunstruction around 6 months ago to see what the lightest rifle I could design was. Granted, some of the part weights aren't entirely accurate but I was able to design a rifle that came out at under 6 lbs.

I'm with you... I don't see an actual purpose for an ultralight build. They are just because builds.

My go to guns are purpose driven, and weight is barely an after thought.

In my personal opinion light is fine. I have a lot of friends with sub 6 lb assemblies. Their rifles feel great but don't handle nearly as well as what I'm used to. I can tell a little diffence between a light weight rifle and a ultra light weight when not shooting, but I can tell a bigger difference in the way the slightly heavier rifle handles. Using Light weight components behind the barrel nut is hard for me to feel a whole lot of advantage.

I know my ipotato photo is horrible. I built this in 2010. Chopped Cav lower, 9mm upper, Clark carbon fiber handguard, 11.5" barrel profiled by ADCO, Precision Machine & Tool titanium carrier, etc.
