Of course. But 300blk supers still have an energy advantage over 5.56 out to at least 500yds. Yes, they drop more but still hit harder.

I have been looking at an SPR (5.56/.223) for distance work for quite some time, but have never pulled the trigger. The main reason, I don't think the 18" barrel gives you that much of an advantage over a 16". In addition, if you're going "distance", I would prefer a larger caliber for better ballistics and energy. An AR10 in .308 makes sense, but that's a heavy pig! The 6.5 Grendel is where I am leaning these days and the plethora of bullets in that category are numerous.
Unless you really want an SPR and a marginal FPS gain, I'd stick with a Recce build (16" barrel) and get a good barrel and optic. Then again, there's the whole rifle length v. mid-length gas system decision...
Caveat: "Marginal" is subjective.

I think the main advantage of the 18 inch barrel is the rifle length gas system. The softer recoil will definitely be beneficial when reacquiring your sights, at least on an SPR setup.

I built an 5.56/223 SPRish rifle and I love it. Like mentioned above its just a precision, medium size , medium heavy AR topped with a mid range variable scope.
Mine was about 1600 for the rifle only. Upgraded parts include a Walther barrel and Geissele SSA-E trigger.
My primary goal since I do not reload was lower cost precision shooting.
If external or terminal ballistics are your primary goal there are better calibers to choose from.

SPR is a intermediate range sniper weapon
SBR is a Short Barrel Rifle
I think you meant SBR

I think he was trying to equate the common use of SPR and Krink as generic terms.
SPR being used as a generic term instead of specifically referring to the Mk12
and any type short barrel AK being called Krink instead of specifically indicating the AKS-74U.

I built one with an 18" Larue upper and geissele SSA trigger. Topped it with a trijicon accupoint 5-25. About half the time run an AAC M4-2k. It's my new favorite rifle. Shoots .5" with IMI Mk 262's. Silenced opens up to 1".
