I agree with you completely on the lightweight market. The interest shown by the market over the last few years has really driven incredible innovation and availability of great light weight parts. Some are practical, some are range toys, but this drives a cycle that allows all to benefit.

Another angle on the V7 Build...

Outstanding. I keep looking at that rail and debating on if I want to jump from a magnesium KMr or not. I debate if I should go with the magnesium oenlithium aluminum model. I really like that Trijicon RMR on the Scalarworks Mount. That’s the route I plan to go soon, and replace my T1 on a Scalarworks Mount.

I’m waiting for TNVC to send me my pro version of the TAPS switch for my light.

The Odin O2Lite was a compromise, if you will, in that the KMRs and their successors are all too skinny to consume a suppressor. I needed something slightly over 1.5" ID and this fit the bill while keeping it fairly light. I'd rather have a V7 Ultralight at the end of the day, just the wrong ID for my needs on this build.

The other 300 build will have a larger OD can so I am going with the Seekins handguard on that one, again not my first choice (it's a nice rail don't get me wrong) but have to get all the various components to work together.

I'd love V7 and BAD to offer rails in a ID of 1.6", in that they offer multiple lengths having an additional ID option would be great, but that's completely selfish of course. :)

I am interested in your feedback on TAPS. I love the concept. Although it does look big.

Question for those running the Battle Arms lightweight stock with the standard buffer tube...how do you guys like it? How is shouldering and fitment/lock up etc?
Link Posted: 12/30/2017 11:47:02 AM EST
I hear you on the rail ID for the suppressor.

I have a Battle Arms Development Billet receiver set that was plated in Np3+. I’m thinking of making it in to a lightweight SPR with a Proof Research Carbon fiber barrel and a NightForce optic. It certainly won’t be in this sub six pound class, but it should be around 8-9 as a precision rifle with its heavy ass optic.

How do you like that BAD stock? Is there any weight savings over say a Magpul CTR and a lightweight buffer tube like the V7 lithium? I’ve been using this V7 lithium buffer tubes with a PWS ratcheting castle nut system that doesn’t need staking. I probably pay a one ounce weight penalty for this though.

The TAPS switch mount well if you are using keymod or mlok. Picatinny gets thick fast. The standard model is kind of a one trick pony and not worth the trouble. The tactile feel of the buttons are amazing compared to the Surefire pads.

Haven't ran the BAD PDW yet, so I can't comment on it other than it's really well made, I picked it up because it allows for a very compact setup while using a standard BCG and is not a add on like many aftermarket options are - just nice clean and compact. While it does accept standard BCG, there are specific dimensions on the tail that must be abided by to work with the non-standard buffer though, just to be aware.

JUST made it...  I've been trying for 20-years to get the wife into shooting ANYTHING..finally decided to go all in and build her an AR of her own.  The stick was meant to be an X-mas present but the PO lost the barrel for a week'ish so it slid to a New Years deal.

5-lbs. 15.05-oz. as configured with full-auto BCG & std. carbine buffer.  The optic & riser weigh 5.6-oz., so 5-lbs. 9.45-oz. naked.

This thread put me over the top to build my first light weight upper.

All said and done I came in at 5 pound 13 oz (Empty with no mag and without the Surefire X300u pictured).

Build Specs:

Upper

Noveske Upper Vltor MUR
Noveske NSR 13.5" NSR
Noveske BCG
Faxon 16" Pencil Barrel
Faxon ultralight .062" gas block
Battle Comp 1.0
Brownells melonite gas tube (mid length)
Noveske marked BCM Gunfighter CH
Daniel Defense fixed sight set
BCM Keymod rail covers
BCM Keymod QD sling mount

Lower
Noveske Gen 1 forged lower
CMMG LPK
CMC 3.5# flat trigger (friggen' sweet!)
Magpul MOE grip
Magpul MOE trigger guard
Magpul CTR stock
Magpul BAD lever
Noveske QD end plate
Tubbs Flatwire buffer spring
Carbine buffer (Brownells)

The rifle feels SO handy and light it is awesome. Thanks for the inspiration and build pics, I can't wait to stretch it's legs in the mountains here soon. I can only imagine what kind of coin it would take to get a sub 5# gun... and how much more hunting, whittling and shopping would be needed to get down to some of these sub 4# guns! Awesome work folks, awesome. I am thinking of a LW BCG but it'll still only shave about 3-4oz (for my price range) but then I think I'd like an adjustable gas block. In the end it'll likely run like this, I could totally fight with this gun.

2A RBC - One of the lightest weight BCG on the market and it's adjustable gas. Two birds with one stone.

That looks great until you look at the price.

It's a cool concept, but a $420 BCG is too rich for my blood.

the CF tube with poly rail on the front puts the front sight a little to high, and with the sight straight to tube is a lot too low. instead of modifying the rail section i might just suck it up and buy a real HG and add an oz or 2.. oh well the cf tube was cheap lol

the poly trigger group is super light, the trigger feels a lot better then i thought it would, its got a heavy hammer spring (i guess to compensate for the weight) but feels crisper on the break then most milspec triggers i have used. i look forward to using it, but dont know how long its life expectancy is

weight with a loaded 20-round mag..

I suppose I can find a few more light weight parts, but first I want to get it to the range and see if it works as is.

ETA:
Got to the range and it did not cycle. Although (in the picture below) it occasionally kicked out brass, it never loaded a subsequent round from the mag. I suspect the gas block but have not had the time to look at it closely yet. I am pretty confident I can fix it.

Wow! With a 14.5" barrel and a little shorter handguard, it could still lose weight!
Link Posted: 9/25/2018 5:47:44 AM EST
I finally got this thing working reliably this weekend by putting a regular weight BCG in it. The lightweight BCG I was using would not come forward with enough strength to reliably strip a round from the mag and chamber it, and often got stuck in the process. I tried using a Wolf extra power buffer spring with it but that didn't help.

Anyway, it works now...

Only problem is, the full weight BCG put the empty weight just over 6lbs.

Do you have a fixed or adjustable gas block? It sounds like your carrier might just be outrunning the magazine. The wolf xp spring is a very stiff spring and is more than enough to reliably strip and chamber rounds (usually excessive in most cases) A test would be to insert a full mag with the lightweight bcg and hit the bolt release. It should chamber every time. If you suspect overgas and you have a fixed gas block then just toss an RCA adjustable gas key onto the lightweight carrier. Then you can have both a lightweight setup that's tuned to work and a full mass setup you can drop in without having to make any adjustments.

Hope that helps. Good luck!
Link Posted: 10/30/2018 5:08:57 PM EST
Forged uppers and lowers, 16" barrels, no polymer FCGs or other small parts, no titanium parts. Steel gas blocks (and one's adjustable).

The Lightweight (with the BCM KMR rail) is right at 5 pounds 7.5 ounces:

The ultralight (ALG EMR) is currently at 5 pounds and change:

However, I have another set of the irons you see on the KMR rifle on the way for the ultralight, as the sights are 2.8 ounces and the PA micro dot (which is frankly awful, as the dot jumps around from shot to shot and will actually cause 2 distinct shot groups at 100 yards, although for HD stuff it would work fine) is almost 6 ounces.  So that should drop it to just at 5 pounds or maybe a hair under.

So I built one using themagikbullet's build (props to that build) for reference with a tweak here and there. I'm at 5lb 6 oz no ammo or mag...not sure why it's such a pig compared to his. The biggest difference is I used v7 gi forged receiver set, 16in barrel but same make and model,  brownells lightweight bcg, v7 telescopic buffer tube and alg act trigger. I guess all that equals an extra lb which surprised me but oh well. It's still pretty light weight.

Very nice. Dig you using the magpul stock in a lightweight. Also didn't skimp on backup irons

Thanks. I have lighter stocks In the junk drawer,  but I like the CTR better. Plus adding weight in the rear isn’t as big of a deal. My goal was t for getting the lightest, but as light as possible while retaining an optic, sling and light. Strip all those off and I’d be in the mid 4’s.

Hi - wow- WITH optics, handstop, sling, light, rail panels and all as shown it is right at 5 lbs?? That is almost unbelievable as I have several ULW builds with similar specs, sling and optics, front site but no other

Sure thing. The V7 lithium aluminum upper and lower are almost as light as the magnesium ones. Except these are stronger than 7075.

Lower: V7 Weapon Systems 2055 lithium aluminum billet lower
Received Extension: V7 Weapon Systems 2055 lithium aluminum receiver extension
Buffer: JP Enterprises Silent Buffer (Gen 1)
Received Plate: PWS Ratcheting locking plate (no staking needed)

Takedown Pins: Battle Arms Development Titanium Lin’s

Flash Suppressor: B.E. Meyers 249
Rail: BCM Original magnesium KMR 13” rail
Barrel Nut: V7 Weapon Systems titanium barrel nut
KMR mounting hardware: V7 Weapon Systems titanium mounting blocks
Gas Block: V7 Weapon Systems .625” titanium gas block, pinned by ADCO
Gas Tube: V7 Weapon Systems Inconel midlength gas tube
Charging handle: Raptor ambidextrous charging handle
Dust Cover: V7 Weapon Systems Lightweight dust cover and lightweight pin
Bolt carrier: JP Low Mass bolt carrier
Bolt: Advanced Combat Bolt if I recall. I’ve had it for years.
Gas key/cam: POF Rollercam with DI modifier gas key
Gas Rings: Spikes Tactical ion bonded gas rings
Rail Covers: BCM over keymod, Larue Index clips with wire looms on the picatinny
Hand stop: Railscales aluminum Karve
Iron Sights: Spikes Tactical lightweight billet sights
Weapon Light: Surefire M600 IB with a IWC M600 backbone body. The switch is a Unity Tactical switch block mounted to the keymod. I may ditch the switch though.
Weapon Light Mount: IWC In-line keymod mount
Front sling QD mounts: Shrike Industries up front and a pair of V7 Weapon Systems QD sockets in the rear of the handguard
Optic: Trijicon gen 2 RMR RM01 3.5moa optic
Optic Mount: Scalarworks RMR absolute co-witness mount
Sling: Blueforcegear padded QD sling

I think that’s everything. It’s light and fast. I’ve put thousands of rounds of SS109 through it with excellent results. Performance wise and accuracy wise. Accuracy steps up when running better quality Ammo such as Taps through it. The barrel nut is never coming off the barrel package since the flash suppressor is pinned in place. I have considered putting a Proof Research carbon fiber wrapped barrel in this rifle. I doubt it would be much lighter than the Noveske, but the barrel would likely perform better accuracy wise.

This one is a hair over 4 lbs 15oz unloaded (4.946 pounds) and doesn’t have a single “lightweight-specialty” part on it. Everything was selected because it proportioned well on a miniature AR or because it was dirt cheap (or both). In fact, I could probably lose a tad more weight and length with a plain birdcage  or other non-mount flash hider, but I want to be able to use my 51T silencers on it.

It's easy now to build an AR308 under 6 pounds, with some effort almost as easy to build one under 5 pounds. Lot of work to get below 4.5 pounds and a miracle to get under 4 pounds. I really thought I would never get below 4 pounds.

Key parts are a Faxon 308 pencil barrel 16.1 inches (also 18 inch) Under $180 when on sale

Polymer lower Tennessee Arms under $50 with discounts

Titanium carrier $$$ but I expect lighter steel ones in 2019, AR 308s are a huge build now, many lighter weight parts are sold out

Hogue polymer 15 degree pistol grip 1.5 ounces under $20, the 3D printed titanium grip @ 0.75 ounces $115 preorder, 2019 will be $125

I prefer uppers without FA, not needed on the AR308. As inexpensive as $100

An adjustable gas block a requirement, without the BCG slams like a sledge hammer

1.  Is it under 6 pounds?

2.  If so, post photos.

3.  If not, well then here's a pat on the head and a "good for you!"
