    What Nate said.
    I don't personally run a CTR without a riser.
    For me the short one is great, but I'm a fool for the LaRue RAS II mounts for my Aimpoints. It's a little lower than normal, so your mileage may vary.
    Do you really think we want laws to be observed? We want them broken. There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. When there aren't enough criminals, one makes them. One declares so many things to be crimes that it becomes impossible for men to live without breaking laws. Who wants law-abiding citizens? Pass the kind of laws that can’t be observed, enforced, or objectively interpreted - and you create a nation of law-breakers.

    I'll definitely be getting a riser. Just unsure of which one. Maybe best to wait until I get everything mounted up. I'll be putting my EOTech back on it so maybe a low riser would be best.

    Fwiw,

    I like the troy micro height on my ARs. With that in mind, I think the 1/2" brings the rail and cheek close to standard AR relationship. I'll use a .5" with low amount micro mounts and troy sights. Those are approx 1-1.2" over the rail for the optical axis. I've got an ACOG that I use the .75" riser because it sits higher.

    Short version... a .5" will get you close to standard AR heights of that's what you're used to.

    Just got my rifle back from coating. Looks good. Next step will be to flute the barrel to reduce the weight of this pig.

    Nice work. Any chance you have some numbers on weight reduction?

    I'll try the low riser first and see how that works.

    I do not know what the weight reduction is. I meant to weight it before and after but unfortunately my scale crapped out right before I started cutting. I do know that removing that little bit of aluminum does not reduce weight very much. I think fluting the heavy barrel I have will be a huge improvement.

    It's been awhile but if I remember correctly fluting a heavy 16 with 6 flutes and cutting the upper to have matching cooling vents all the way around each saved 6-8 oz. I'd have to go back into some old threads to double check that.
