So I was thinking about using some spares and building the lightest possible AR, perhaps sub 5lbs.....

Has anyone built a car/m4 size AR under 5lbs and how did you do it?
Here is what I was thinking might get it started:
Oly arms a2 upper with a1 sight and any basic aluminium lower.
a pencil barrel cut to 14.5 and fixed vortex FH
ace skeleton ultralight stock
poly mags?

What else?

Thanks guys and gals, you are the greatest community anywhere!
when are we gonna build a trailer park for arfcomers? my lease will be signed first!

I think it could be lighter if you had a $200 tax stamp on it.

You can try, but you won't be able to get it below 5 lbs. My lightest is right at 5 lbs. 14 oz. with an empty mag. With the pinned mod its right at 16 inches. The barrel itself is about 12.5, so the moderator doesn't add much more than what a 14.5 with vortex would be. Good luck.

Start with a Bushy carbon rifle and take a dremel to it, Im sure you could get it below 5 lbs.

A few hints:

You DID state "lightest possible"!

Aluminum bolt carrier
Aluminum gas block
Barrel turned to .550 (Randall @ ar15barrels offered this dia.)
Shorten barrel to 14.5" and fixed Phantom (lighter than Vortex)
Carbon fiber upper & lower receiver
Pre M-4 Colt collapsing stock with lightweight buffer
Drill through the centerline on the takedown and pivot pins
Drill through the right side center of the safety
Use a JP Enterprises lightweight hammer
Drill a hole in the middle of the serrated part of the bolt lock
Plastic trigger guard
Doctor red dot sight


There are a few other modifications but they are a little harder to describe.

This will get you to darn near FOUR POUNDS

A Cav arms complete lower will save you roughly a pound over a conventional lower with a CAR stock.

Slick sided upper with no FA.

The LaRue Irondot combines an optic and BUIS, yet only weighs a couple of ounces.

Non heat shield handguards
skeletonized bolt carrier like from Young Mfg
standard weight carbine buffer
non forward assist upper....perhaps a flat top & run one of those mini Aimpoint or Docter red dot scopes, shaved gas block without front sight, no bayonet lug
maybe a 11.5" lightweight barrel with a swiss cheesed 5.5" FS
A retro Nodak slabside lower will shave a bit of weight

Here's one I put together a while ago.  Wish I still had it.



Bushmaster CF upper
Cav Arms lower
16" light weight barrel
shaved gas block
DPMS CF FF tube

I never got it on a scale, but I'd bet it was real close to 5lbs.  A JP Low Mass carrier would take off a good bit of weight too.

The car on the bottom comes in at 6 lbs even. If you got rid of the rear sight and went to an aluminum gas block with a fastfire or doctor sight you would be getting down there in weight.

Standard Bushmaster pencil barrel and rest is standard stuff.

+1 for the cav arms lower w/ integral stock.

One of these with a pencil weight barrel and you'll be well under 6 pounds.

This KISS carbine weighs in at 6lb 1oz with an empty 20 round mag inserted.  It would be a few ounces lighter with a standard GI flash hider install in place of the BM slipover.

My lightweight comes out to 6 lbs 5 oz, probably due to the aluminum stock, 14" barrel (a little over 3" under the mod) and heavy BCG.  Having said that, it's the best handling one I have, and my favorite.  I've got a form 1 in now, so we'll see what happens.

Friendly competition between myself and a friend as to how light an AR-15 was possible. It has got to the point of being ridiculous when you are looking to shave another 1/2 oz. One of the items he did was turn down the diameter of a standard A1 birdcage flash suppressor. He even milled away part of the Colt buttstock (the plastic part).

I'll see if I can take a few pictures in the next day or so.

One thing I'd do differently is now I'd go with the JP Enterprises JPBC-3 Stainless Low Mass Carrier. I purchased one for a new build, it's not as light as aluminum, BUT, it will take a hell of a lot more abuse. The aluminum carriers tend to go to crap after around 1000 rounds.

I wouldn't work on the door, either leave it alone or remove it. For an upper receiver look at the Rock River Arms 9mm flattop. You will have to mill the area for a gas tube, clearance for the bolt carrier key, and the bolt cam pin but it will be a heck of a lot lighter than a forward assist receiver with the brass deflector.

Actually in most cases it's been a Bridgeport Mill or in some cases a Dremel Tool. On "Project Lightweight 2" I'm excluding the carbon fiber upper and lower receivers and aluminum bolt carriers. I want a AR-15 that you wouldn't be afraid to take into an IDLH (Immediately Dangerous to Life & Health) situation. That means A LOT of time on the mill, My goal on this project is sub-5 lbs. If I can bust the 5 lb. barrier without resorting to items I consider borderline on reliability I'll be happy.

Barrel turned to .550 (Randall @ ar15barrels offered this dia.)

Aluminum gas block
Shorten barrel to 14.5" and fixed Phantom (lighter than Vortex)
Upper & lower receiver milled on the outside to thin them (Think FN-FAL Type II) NO HOLES
Pre M-4 Colt collapsing stock with lightweight buffer
Drill through the centerline on the takedown and pivot pins
Drill through the right side center of the safety
Use a JP Enterprises lightweight hammer
JP Enterprises Stainless Lightweight bolt carrier
Drill a hole in the middle of the serrated part of the bolt lock
Epoxy on the pistol grip (eliminates the weight of the screw) (AGAIN, after a point it becomes crazy)
Plastic trigger guard

I may have to go the SBR route to get below 5 lbs. but that is the goal.

I'd start with a Nodak Spud slabside lower and Les Baer flat top, no forward assist upper and Ace ultralight stock.

If you're going with iron sights an early m-16 A-1 upper with the carry handle cut off would be a good start.

The only problem with the Les Baer flattop is that it still has the brass deflector.



Take a Rock River Arms 9mm flattop upper, do the necessary machining to convert it to 5.56, install a standard dust cover assembly and you're good to go!

I had to weigh my 653 repo after reading this.  As you can see below my LW is 6.01 pounds.




It's not totally accurate but it's legal and it's my KISS rifle.  I don't know where I'd start to get it below a 5 pounds but you guy's might have figured out what my newest build is going to be!  My wife loves it when I get these ideas in my head.

I would sure like them to be super thin stainless with carbon fiber wrapping, but the website claims they are practically normal lightweight stainless barrels underneath, and specifically states that would be safe to fire even without the carbon fiber wrapping.

If weight is the goal, I would love to see a true super thin barrel with most of the strength from the carbon fiber.  There may be too much liability risk for a company to actually offer this though.

You could live without the front handguard.     And use a lower with a skeletonized magwell.

Replace the stock with a lightweight foam pad just secured to the end of the buffer tube.

Skeletonize the buffer tube, too.

Lose the FSB and put on a lightweight gas block and use a very lightweight laser as your
sighting device.


I'll bet you could get near 4 pounds if you were creative.

Yes, it's a one piece tube.  I had to drill a small hole to access the set screw for the chopped gas block.  I think it plenty strong enough to mount a light or sling to.

I saw a post where someone from Calvary Arms stated that you couldn't cut off the buttstock and thread the receiver ring for a standard collapsing stock. (That blew what I considered one of my better untried ideas)

I don't think you could "hog out" enough material to make a significant weight difference.
