    My gun is 7.5 lbs unloaded, with T1 in an LT660, inforce wml, mbus sights, precision armament EFAB, bad lever, and iwc keymod sling mount.

    This is with some V7 parts and the 13" KMR. BCM stock.

    You can't get a FSB 18" with this barrel to be that light, or to have a center of gravity that close to the shooter.
    I don't have a weight goal. I just don't want to keep the weight manageable without spending a lot of money for features I don't need. The MOE costs about 1/8 of what the KMR does, and will allow me to mount a light, which is the only add on I'm considering at this point. I'm also planning on putting it on a Cav15 lower, so with the right upper 7.5 pounds is not out of the question.

    Did you happen to measure the gas port diameter before putting it all together?

    That barrel would be perfect if they just made it in a true pencil contour. A 20" pencil option would also be very nice.

    It's MK12 spec. .098 to .100.

    Voodoo innovations has an ultra light 18".

    However, the center of gravity will be much further away from your body than with a lightweight Handguard and no FSB. Calling it front heavy would be an understatement with the cav arms lower.

    Just know what you're getting into. Your going to have a 7.something pound gun that handles like an 8.something pound gun.

    What sort of irons only upper would you suggest for a cav arms lower, in that case? I know that balance is important, but it will be carried a lot more than it will be shot, in this case. I am dead set on this lower, as I want a fixed stock, and this is the lightest way I have seen it available.

    I've been looking into it, and there's actually a lot more of the non railed, smaller diameter free float tubes that weigh about the same as the MOE. Depending on the cost of other components, i may be able to make that happen. Both MI and Troy have offerings, that I've found so far.

    Getting a reliably decent barrel is more important, so I'm reserving more funds for that foremost.

    You're forgetting that a FSB weighs over 4oz while a low profile gas block weighs around 1.5.

    EDIT: A V7 titanium gas block weighs .7oz.

    Something with a KMR and either that Rainier mountain series barrel or one from voodoo innovations in their ultra light profile.

    I'm not going to try to talk you out of your cav arms lower, but I'm not a fan. Let's just say I've personally seen two fail in a catastrophic fashion during routine training. They are banned by my agency from being used in our personally owned patrol rifle program. I'll leave it at that.

    Moving along.

    But that doesn't include the added expense and weight of the rail mounted front sight, an absolute necessity on an irons only rifle.


    I'd like to hear more about the Cav lower, if you have the time and don't mind PMing me about it. The new manufacturers torture test video is interesting, but I always prefer 3rd party experiences to manufacturer claims. This will not, however, be a duty rig, and it's very unlikely that any lives will ever depend on it.
