Mine weighs 9lbs with a 1-6 and light. I can't get it a whole lot lighter without spending some serious money or possibly compromising reliability. Just curious to see what everyone else is running.

What configuration are you using? I had a 6-7 pound BCM LW 14.5 middy upper with T-1 and Magpul MOE hand guard. on a Stag lower with DD/ALG FCG, H buffer and Magpul furniture that was reliable with .223 wally world and 5.56mm XM855 and XM193. I mostly used 5.56mm.

I suspect a good chunk of your weight is in your optic.

I'll point out that actual weigh in pounds or kilos is only part of the story. IMHO balance of a rifle plays into how it feels shooting it.

I have one that'a bit over 9 pounds with a drop in rail, back up iron, Aimpoint Pro and Surefire light, and another that a KISS build with A1 upper and pencil barrel that's under 5.5 pounds.

A lot depends on the intended use. If you are using for HD, you may only want red dot and maybe a light. For longer range, you'd probably have a heavier optic and ditch the light, and may have a heavier profile barrel. Also, some guys run SBRs or "pistol" ARs, others have 16"+ or pinned barrels.

You could get dozens of weights running anywhere from 5 to 10 lbs, but without specifics the number isn't necessarily meaningful.

The optic and mount I have weigh almost 2 lbs. It was certainly lighter with the aimpoint. I was just curious what the average weight of some AR rifles with all the battle rattle on.

Mine was ±5 lbs. before I put light and optic on it. Neither of those weight much, so I doubt it's over 5½ lbs. or so, now.

I wasn't going for light-weight. It just ended-up that way.

Just under 6.5 with light/optic. I have others and weights depend on intended use but vary from 6.5 to over 9.

My 14.5" with Leupold optic weighs in at just under 7 lbs without a mag.

Primary training gun is a Colt LE6920 with Aimpoint CompML3 and Magpul furniture: 8.2 pounds.

Serious purposes guns.

Close quarters is a Colt LE6920 with Aimpoint CompML3, Magpul furniture, small vertical foregrip, Surefire X300 and tape switch: 9.15 pounds.

Intermediate distance Colt LE6940 with Leupold Mark 6 1-6×20mm scope, Spuhr mount, Surefire X300 and tape switch, Magpul PRS stock: 10.5 pounds.

What was the base gun? Dont see too many sub 5lb AR's

My lightest is just over 6.25#. With MBUS and aimpoint pro red dot. I love it.

Makes my AR10 feel like a cinder block.

I keep my SP1 as light as possible. I only use 20 round mags to keep the weight down.

Even with the IDF optic it is around 6 lbs.

the krieger barreled A2 ia right at 14lbs,

the short range gun I have is just about 13,

put together a NM for optics, but have not had a chance to weigh that yet

The latest one I finished a couple of weeks ago weighs around 8 1/2 pounds empty with an 18" barrel, 12" full float, scope with mount and a Magpul ACS stock...it does not feel that heavy though.

11.5" BCM with KMR, Aimpoint T1,Magpul Pro buis, SilencerCo Omega weighs 7.5lbs without mag/ammo.

I agree with this.

When you approach 9+ lbs with an AR15 you are defeating the purpose.

My new build, 10.5" 300blk, is 6.8 lbs incl optic and empty 20 rd mag.

What purpose is that?

It depends upon the purpose.

My 16" carbine weighs 9.8#, the 18" rifle 11.2#, the 20" weighs 12.4#. All include bipod and variable power glass. The 20" rifle has a PRS stock.

These ARs have been used in run-&-gun matches, in both single & multiple gun formats -- where I also have to carry a pistol or precision rifle at the same time. All matches have been under the clock. Usually carrying a pack with food, water, ammo, storm clothing, & improvised support equipment. Generally at altitude, in heat/storm/cold, over rough terrain. In some matches jogging between stages to meet time limits, moving a few miles per day.

Targets range from "A" zones on reduced sized IPSC at 5-50 yards, to 3-4" steel at 100-150 yards, to 12" steel at 300-600 yards. Sometimes distances are known, sometimes they aren't. Occasionally we get to shoot from prone. More often the shooting positions are unsupported, slung, improvised over rocks & trees, or from tripods.

Google Team Safari, Nightforce Precision/Tactical 2-rifle, Competition Dynamics Team Challenge. Lightweight ARs don't do so well in such venues. And it isn't benchrest shooting on a square range.

6.5 pounds

Bravo Company 14.5 LW write original KMR 13
Aimpoint T1 on Fortis F1 Mount
MBUS PRO Sights
Inforce WML HSP on IWC mount
BCM Mod 0 Stock

It's over a pound lighter than my 6920 with DD Lite 2, EOTech XPS2, DD sights, X300, and CTR.
