    Ya, I am having trouble finding any reliabe data on this, I started a thread in the NFA section to see if anyone has any info. I could see maybe an AAC mini4 but I always think about the 1/4lb flashhider/mount that has to be added to it.

    Not sure how you could add a light, optic and sling and keep it ultralight. I did weigh it with an X300 and Aimpoint T1 in BOBRO mount and it came in around 6 lbs. 11 oz. That's still under 7 lbs. I think some people are really over obsessing about the weight.

    All these KMR posts are seriously making me consider building a rifle or two up with one.

    Then you get something that direct attaches like the Ranger-3 or maybe the Gemtech Trek-T.

    If anyone complains about weight with a KMR and ELFW, then they seriously should start lifting. With the base gun with the new MBUS Pros, the weight is barely more than merely lifting your arm up. Senior citizens at the YMCA lift more than that...

    People will always complain though.

    Nice gun dude.

    Easily sub-6lbs if I put a 13" KMR on this rifle to replace the 11" NSR. At 2" longer and 2oz lighter (7.7oz vs 9.8oz) BCM really knocked it out of the park with the KMR. I don't plan on changing handgaurds though.
    To that end however, project uberlight, is coming along well with a 14.5" ELWF and 10" KMR, projected to be in the low 5lbs region.

    6 lb 11 oz would be a lot lighter than the ones I'm running now. Never really thought of them to be that heavy, but I'm guessing they're on the porky side for a 5.56 rifle.

    As for the weight, I guess I'm just geeking out over the weight because I'm kind of excited to see what new materials could do for gun & accessory design.

    Iraqgunz is absolutely right. I think people are starting to over obsess with tenths of ounces here. It is awesome that the KMR shaves several ounces off the weight of the gun and provides an awesome lightweight rail. However, people should get what they like, not something else just because it is .3 ounces lighter. Lighter weight is usually good, but if you gain something with that increased weight or have additional capability, it is sometimes worth it. One example, at least that i found out for myself dealt with optics. I had a T-1. Then i realised that i could get a Trijicon RMR and save even more weight. After getting the RMR, i found out that the weight savings was not worth it. For me, the T-1 was a far better optic for me. If there is something to be gained from the weight, it could be worth it. A most extreme example would be having sights on a gun period. We can save weight by getting rid of sights and optics altogether. I don't think there is a single shooter out there who would say that it's smart to save weight by removing sights altogether. We don't want to start sounding like, "Do these jeans make my ass look fat?" I guess.

    I have the 13" KMR Fluted ELW upper, Troy sights, a SureFire G2X in a HSP Thorntail mount, Vltor A5, and a Vortex Razor 1-6x. It is just about 9 pounds.

    If I take the scope off, I am looking at 7 pounds.
    It is from the construction of underground FEMA camps. I can't say more because there a guy parked in front of house in an AMC Pacer. He is acting like he talking on the phone, but I know better.

    I have to sign off now & put my laptop in the microwave.

    That's a very nice rifle. I just got a 16" BCM BFH lw middy and put the 12" Fortis rev rail on it and it is around the same weight as yours. I love it!
