 How Much Does The Average AR-15 Weigh?

I just received a new Rock River Arms Tactical Elite AR-15. I love the rifle, but it sure seems heavy! I am new to the AR world, and to rifles for that matter. I have always shot pistols until now.

I was showing the RR to a police officer friend of mine who carries a Colt 6920. He commented that mine seemed pretty heavy.

I put it on my digital bathroom scales and it weighs in at 9.6 lbs.!

Is that normal? Heavy?

That is the mid lenght gas system with a rail right?

The rails add a good deal of weight to the guns.

Rail, optics, light, sling, full 30 round magazine, even a heavy buffer can add a couple ounces. The more stuff you hang on a rifle, the more it's gonna weigh.

Sorry, it's an Elite Operator. Heavy barrel.

Yes midlength gas system with rail and Leatherwood scope.

RR says it weighs 8 lbs. with nothing added.

I am just wondering if 9.6 lbs is about average for an AR-15.

2 lbs heavier than my Noveske reece, but I don't have any extras. Get some sand bags and wear out some 300 yd targets with that RR hbar.

The heavy barrel adds about a pound which is a lot of weight when you are talking about 8-9 pounds. I have two guns one with the RRA heavy and the other with the lightweight––big difference. Also the upper barrel assembly may be a poor weight match for the lower resulting in an unbalanced gun. This results in a gun that is uncomfortable to carry and shoot.

It all depends on what you deck it out with. A heavy barrel adds a pound or more compared to a lightweight one. Heaver rails will add weight, especially if you have to put rail covers all over them to be able to hold them comfortably. You can also get all manner of heavy stocks that can fit batteries, and many optics can be a pound or more as well.

By way of illustration, a lightweight build can be as low as 6 pounds without doing anything fancy (i.e. no special low-mass bolt carrier, carbon fiber handguards, cut down front sight block, etc.). Replace its barrel with a heavy one and it'll be 7 pounds. Replace its stock with a heavier one and it'll be 7.5 pounds. Replace the handguards with a quad rail and rail panels and it'll be 8 pounds. Add a light and a vertical foregrip and it'll be 8.5 pounds. Add an EOTech on a LaRue throw mount and it'll be 9.5 pounds. Add a loaded 30 round PMAG and it'll be 10.5 pounds. The gadgets and goodies add up. An ounce here and an ounce there will make all the difference when you put them together.

Here's a great calculator for you to use to figure out how much a rifle will weigh with different gadgets on it.

My 6920 with a 14.5 Socom upper (Heavy Barrel) and Aimpoint is around 8 pounds

Not sure what my 4 ARs weigh, I would guess less than a lot pictured here. Not a fan of rails and mounting 87 pounds of tacticool accessories on my carbines.

Carbines. You know, shorter rifles, supposed to be light and handier than a full size rifle. IMO they should not weigh what an M1 garand does but that is just me

9.6 lbs sounds pretty heavy, but I guess the heavy barrel, rail, and scope can pork it up pretty quick. My Noveske weighs 6.4 lbs, but it is a 14.5" with iron sights.

just one more reason why I absolutely hate RRA uppers, heavy barrels don't belong on an "M4" carbine, they just don't.

I would have to agree. I wouldn't want to carry around that much weight all day.

I will have to look for another, lighter, upper.

An average AR15? Yeah, it weighs about as much as your average dog.

The RRA is heavy for an AR15, but the rifle can vary in weight anywhere from 6.5 lbs to 12 lbs, depending on what you buy - Superlight or DCM, or something in between. Define your average rifle, and you'll have an average weight.

AR-15 have gotten heavier over the years.

My 16" slickside carbine weighs 5.6 pounds (about as light as you can get with a 16" barrel and aluminum lower)
My SP1 weighs 6.5 pounds with sling
My M16A1 clone weighs 6.9 pounds with sling and 7.4 pounds with cleaning kit
My M16A2 clone weighs 7.6 pounds with sling
My 16" barrelled M4gery weighs 6.9 pounds with sling
My 20" heavy barrelled Varmint AR with 6.5-20 scope and bipod weighs 11.4 pounds.

As noted above rails,neavy barrels and optics quickly add weight to what used to be a lightweight rifle or carbine.

I'd say 7-10 lbs depending on how much stuff you have hanging off of it.

I had a RRA upper with the heavy barrel, and yes, it seemed heavy. I had Adco re-profile the barrel to govt. and shaved off 10 oz. The rifle has much better balance now.

7.5 lbs unloaded. Hoping to drop it near 7 lbs even by cutting it down to 14.5" and reprofiling the barrel.

I am one of the few who actually prefer the heavy barrel ( HBar). If you want it to balance more you can add weights to the stock. But in all honesty if you won't be carrying it all day who cares what it weighs? If it bothers you that much there is plenty that you can do to lighten it up. Or joing a gym and you won't notice it as much, lol!!!

TacYellowVisor, Vuurwapen, 03 DG joint work - this fantastic AR weight calculator.

http://www.545ar.com/calc.html

This matches all the weights I've gotten pretty closely, ranging from 6.8# loaded up to my 11lb SPR, and has caused me to reconsider the merits of my SOCOM profiled barrel.

No, it's heavy. I thought my middy HBAR carbine was heavy but it's only 7 lbs 13 oz. There really is no such thing as a typical AR, but I imagine the great majority would average between 7 and 8 lbs. Weigh it with only permanent accessories like optics. Take off the sling and remove the magazine.

Most ARs running an optic, rail system, and light are probably going to be around 10lbs loaded.

The previous posters who pointed out 'balance' (or lack thereof) as one of the culprits are spot on. My first personal AR was a Colt HBar; I was happy as a pig rolling in shit with it, but it just didn't feel like the A1 I was issued forty years ago....
It was a PITA to shoot offhand, not that it was crushingly heavy, but that it was front heavy. I eventually had ADCO give it the Jenny Craig treatment, and finally built an A1 clone to replace it.
That, BTW, feels GREAT.

Also keep in mind that your bathroom scale is most likely not very accurate at that low end. Try taking your weight holding the rifle then your weight without the rifle and do the math. See if it comes up any different.

Luggage scales like this one work very well.

My RRA weighs 8.25 lbs. after it's taken a good mag dump.

Normal? Depends on who you ask.

Basic HBAR carbines (16" barrels , A2 upper & stock, carbine gas system) weigh in at 7.5 lbs - that's the same weight as a 20" M16A2 with a govt profile barrel.

It's the Heavy (HBAR) barrel under the handguards. It adds weight, and to compound matters the weight is on the barrel (which is acting as a lever) which makes it seem like more than it is.

For the military it's not 'normal', for companies trying to cut costs by reducing machine time, it's normal (and they will tout it as an improvement).

Interesting. Wonder if it's sensitive enough to also measure trigger pull weight?

Well, the AR-15/M16 platform is in it's 40's now...so a little fat around the middle is to be expected, right? It amazes me that the "space age plastic gun" can weigh in as a heavyweight. An M1 Garand typically weighs between 9.5 and 10.2 lbs unloaded (depending on the density of the wood used in the stock and the type of sling). Obviously the extras do add up and I have no idea how much mine weigh. Of course weight isn't as much of a concern to me as balance.

+1. I agree with this 100%. I prefer a HBar over the cut barrel.

it's sensitive to a tenth of a pound and to 1/20th of a kilogram rather than to the once, so it depends on how picky you are.

A bigger issue is that it will not record the peak weight unless you hold it for a few seconds, so you'd have to be watching the display when the trigger breaks.

I don't know about an average weight but i think most people weigh their rifles on a cheap bathroom scale or guess.
So i take them with a grain of salt when they quote those crazy light weights.

LMT 16" govt profile brl upper
osoe sling , tlr1 , little bit of paracord
28rnds in the mag

OK, so no "standard" weight. Mine looked neat, but sure felt heavy.

So I went to the gun show... Now I have a Colt M4 upper.

The rifle is MUCH lighter now. Feels more like I imagined a combat rifle should.
