3.414lb Lightest AR-15 in the world shooting video


I may do a breakdown video this week. I've got 500 rounds through it now.

3lbs 6.625oz

Maybe it's click bait, and maybe it's the lightest! Haha. Lightest that falls under the given parameters of no polymer, no standard parts left off, no holes drilled on parts to lighten, must be rifle length.

If I'm not mistaken, that's the 22LR conversion that the mad scientists at 2A have been developing.

Pretty pleased with this build, only thing left to add is an inforce wml and it'll be finished at 5lb 6oz.  If I were to remove the direct thread omega with titanium adaptor and front cap and go with a faxon fh, take 10.5oz off that figure

Put together a lw coyote rifle too.  Optic/mount combo is right at a pound iirc, 18" faxon gunner, standard bcm bcg, h2 buffer.  Might be fun with my ta33 too.

4.98 pounds and it even looks like a regular rifle. I know I could have saved more weight with a skinnier barrel, different handguard, and possibly a minimalistic stock, but I wanted it to look as clodr to a 'norma' AR as possible.

Looking great! I’ve been following your build thread, did you mention what color you are doing when it’s done?

Function tested and zero'd the 18" with wolf gold, shot really smooth and stacked the brass in a neat pile between 4 and 5 oclock.  Hoping for an honest 2-3 moa from the wolf with the lpv and non-match trigger, and will do some group testing with some gold dots and match type ammo soon.  I actually had an old spikes buffer in there instead of the h2 as mentioned earlier-I think st-t1? haven't used those in a long time but worked out perfect.

The 11.5" with omega, faxon lw carrier, and carbine buffer got set at 6 clicks open on the slr gb, ejecting 2-3 oclock using 62 gr fusion msr.  What a fun rifle, feels like a toy but shoots great.

I recently put together a lightweight build for someone.  Looking through the thread I thought I'd hit close to the 5 lb mark as there (at a quick glance) appeared to be quite a few normal looking rifles that hit the mark.  I was a little disappointed when it came in at 5lb 13oz with the red dot.  Was I just expecting too much?  This was a budget build so I used stuff I had sitting around with some new stuff.  I wanted it lightweight and as soft shooting as possible.

Specs are:

Anderson Lower
Regular upper but with FA plugged.  (could have saved an ounce here maybe with a slick side but already had the upper)
Faxon pencil Barrel
Superlative Adjustable Gas Block
Empty Buffer w/ reduced power spring
Lightweight AIM BCG
Guntec Rail which was the lightest one I could find (7.7 oz IIRC)
Everything else not listed is just regular Milspec stuff.

I see areas where I could clearly shave some more weight but then stuff starts getting expensive because it's titanium or special parts like Battle Arms stuff which isn't cheap.  Am I missing anything obvious?

[Last Edit: MackDaddy1962] [#22]
You’re right brother, getting it down to 5lbs is expensive.

You can save quite a bit of weight by losing the Magpul CTR and optic. Replace with an MFT BMS stock, and VV 3MOA RD on a UTG LW .75” riser. These won’t break the bank and work wonders. I use the MFT stocks on my carbines, and Vortex Venoms on all of my builds.

Good job! As long as it shoots good and you like it that’s all that really matters!

Rock on,
Jim

5lbs 7oz.

Including Suppressor. I don't think there are other under 6lb suppressed builds, could have missed some though.
Barrel length is ~8 inches. Effective length including dedicated suppressor is about 12.5 inches.

Lots of room to cut weight if it was that type of build. Has optics, irons and a light for one. Wouldn't have a suppressor if I was trying for uber light. This was a "Practical" build compared to my 3.5lb build, and there were some items I wasn't willing to drop, but I wanted as light as possible while meeting the design goals. This isn't intended to be a stealth shooter, just enough to be tolerable to shoot indoors in a pinch.

Shot her today, she's a killer.

Think... Honey Badger or Spikes Compressor - but lighter ... and better IMO. Shorter than some configs as well. I was definitely inspired by them.

Building a similar one on a BAD PDW, 2 is 1, 1 is none.

Yes sir. Gives you that HoneyBadger-esque type setup.

Just waiting on the Can to be cleared by our ambivalent government.

I believe it will be right below the 6lb mark. The idea here is to reduce length but in order to do so, you sacrifice weight.
The White Cardboard Tube represents the Can OD and Length. Barrels are the same ~length on the builds. BAD build will have a heavier reflex can on it that goes back over the barrel, making the overall length (combined with the PDW stock) shorter on that build. But again, heaver.

Yeah, I think we need a thread name change. At this point a 5.9 lb right isn't an ultralight...it's just light. Sub-5lb would probably be a better cut off, and honestly, most people intentionally building a rifle where in weight savings is consideration #1 are prolly shooting for sub 4lbs.

Not bad. My lw build with poly lower is 3.8lbs with Magpul BUIS, about $1300 invested. I have a Mag tac lower on another build, with generic CMMG or Andersons LPK, that would be closer to yours. The biggest $/oz savings for me was the Smoke Composites stock, probably next was v7 Hyperlite 11.1" rails.

While it is fairly easy to get a carbine under 6lb (Colt 6520 anyone?) I would say that they are far from average.  Lots of ARs on arfcom are pushing 10lbs with optics, lights and sling.

6lbs, all in is still a noble goal.  And by that I mean include optic, light, slings and any other accessories you’d run it with.  It is challenging to get under 6lb that way, especially with a magnified optic.  I’m planning a lightweight myself but I’ll be happy if I’m under 7lb all in with ACOG TA33 and a light and sling.  I’ll be using fairly stock parts as well which makes it harder.  I don’t have the cash to throw at ultralight titanium parts.

There's nothing ULTRA lightweight about a 6 lbs rifle. There's nothing wrong with building a rifle or building a lightweight rifle, but it does seems silly to build a 6lbs rifle and call it ultra lightweight when there are guys putting together 4lbs rifles with parts you can order straight from a manufacturer. Then you get the real sickos who are further milling those parts and hollowing out screws pushing for 16" 3lbs guns.

I have a 6720 that weighs a smidgeon under 5lbs with iron sights. Yep, still has a Colt full mass carrier, Colt pencil barrel, and Colt carbine buffer system. With an ACOG mounted, still under 6lbs. Really, the only thing you're replacing is the FSB, handguard, buffer tube, endplate, castle nut, port door, selector switch and a few other small odds and ends with Al and Ti counterparts. Average, nothing exotic, didn't cost a small fortune, and hardly a daunting task. I've had that rifle for years and years.

IMO, ultralight is 4.5lbs and under with optic.

Depends on the build. When you add suppressors, lights, optics and sights, and make a field-able rifle and not just a hobby driven range queen... 6lbs is pretty ultralight. I have a 3lb 4oz build, but it also has a New Frontier Armory FCG. Does it go bang? Yup. Would I choose it to defend my life.... nope.

I've posted one uber light in this thread, and two other SBR actual field-able rifles that come in under 6lbs, but also have supressors, lights, real optics, BUIS, et al.....  I am also in the process of building a 6.5G build that will have a scope, a RMR, A supressor, a 16" Barrel and it will still be under 6lbs.

I will grant you, there are many folks just doing basic off the shelf style rifles that are under 6lbs and it doesn't queue any of my interest. But I am interested in the true ultra light hobby guns as well as the complete practical builds that keep it as light as possible.

A silencer is a requirement for a "fieldable rifle" now? Why not a grenade launcher, while we're just tacking on the fun stuff? OPs rifle didn't even have an optic, a light or a way to mount one, at all.

No. Not at all. Not what I meant. However, if you can build a sub 6lb suppressed rifle with light, optics, sights and have 100% field-able parts and not things like NFA FCG, I think it's noteworthy and a topic I am personally interested in and want to see more of.

If you are building a safe queen / range gun type firearm and you barely make it under 6lbs and only have irons on it.. well... that's pretty boring IMO. Under 4lbs gets interesting for these types of builds.

I suppose two closely related but different topics of interest.

I appreciate all the light weight parts the industry has responded with and while I have a uber light build myself, and will rebuild it with even lighter parts when I think the time is right.... I am generally more intersted in leveraging the parts and technology for real builds to see how light I can make them while remaining practical in that build is not fragile and is field-able.

A stock 6720 weighs around 6.1 pounds.  That means you’ve managed to shave over a pound and still have a functional rifle that I’m sure will serve you well.  Under 6 with an ACOG?  Even better.  It sounds like you’ve still used a lot of small Ti parts, what’s your definition of exotic?

You’re rifle sounds like a great build and I’d certainly appreciate seeing it.

Why do they have have to be super exotic or expensive to be ultra lightweight?  Personally I’m not interested in rifles that use a lot of carbon fibre, composite lowers and the like.  Anyone can throw a ton of cash at specialist manufacturers and build an Ultra Light for Uber bucks.  They’re certainly able do what they want with their builds and some of them are neat but I’m just as interested in rifles that use fairly stock components and still come in under 6lbs.  Is it particularly hard or challenging?  As you’ve pointed out, no.  But neither is throwing thousands at a build, it’s just money.  Now some are doing a lot of lightening themselves and those are really interesting.  I’m jealous, wish I had the equipment and talent to something similar.  I’m not sure what my point is at this point.  That they’re all interesting and relevant I suppose.  It’s the OPs thread, you don’t need to contribute or you could certainly start your own with a 4.5lb max weight.  My build will be a long term project as I’ll put it together as time and money allow.  At this point I doubt I’ll post it here because I don’t need anybody trash talking it because it doesn’t fit their criteria.

Well, they don't have to be, but AR15s start out fairly light... so if you're not making significant gains, you're not really 'ultra' light.  Barrel and BCG will get you light...but to get ultra light (and maintain quality), get out your wallet.

If they were similar in cost to milspec parts would you be interested?

The interest in light weight in significant enough volume is what has brought the parts to market. As volume increases, manufacturing methods improve, etc, the better this gets for everyone.

When this thread started 6 lbs was a reasonable goal for an ultra lite.  JP or used Smith or PM&T BCG were the only lightweight options.  Lightweight barrels were pretty much non existent.  Lightweight receivers were pretty limited as well.  The Clark carbon fiber was the only lightweight handguard.  The plethora of lightweight parts is a fairly recent phenomenon.

If they were proven to be as durable, sure.  I agree that the more products that are on the market the more the cost will come down.  Maybe I’ll use a Titanium pistol grip screw just to say I’ve got something exotic.

Josh Ashton makes a great point.  Most of these parts are a recent phenomenon.  Lightweight handguards (aside from Clarke’s carbon fibre) came on the scene with Daniel Defence.  If you wanted a lightweight you were stuck with a Colt 6520 or a Bushmaster pencil or building it yourself.  I’m still living in the dark ages.  Most dealers in Canada have not latched on to the lightweight market.  A government profile is as light as most carry.  A few years ago when I wanted a lightweight build there was nothing available up here at all.  I ended up buying a Stag 16” that had been turned down in front of the FSB to pencil profile.

I certainly welcome new products and think that some pretty interesting things have come to market the last few years. Let’s just not assume that it’s not light because we can build it lighter.  I’ve been using the AR professionally for over 20 years and I’d give my left nut for a 6lb Carbine with optic.  Instead I’m saddled with a C8A3 that weighs over 9.5lbs with an Elcan.  Our M203 weighs an extra 2lbs over the US version.  Throw on a light and an IR laser and I’m likely pushing 11lbs for a 16” Carbine, throw on that M203 and it’s closer to 15 so you’ll have to excuse me if I get excited by a sub 6lb fighting rifle.

Nada-Nada -
Love that lightweight with the integrated suppressor. The main purpose for pushing this market to develop lightweight components is so that the user can add things like a suppressor, lights and optics without being penalized by the weight.

It’s not about the gun being light and easier to carry as much as it is being faster to move from target to target and to midigate the weight penalty for accessories.

Thanks....

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...
