Welcome aboard,
.
While the Bushy is an excellent choice, this is most accurate outta the box long range AR15 I'm aware of:
www.colt.com/law/car.asp.
I own one and have seen more than 6 of 'em, everyone a winner.
You'll need a Jewell 2-stage trigger and a good mil-dot Leupold scope, but should ya go this route and use this load, (see below) it'll never be a disappointment to ya.
Sierra 77grn. MatchKing
24.0 grns. Accurate 2460, (
Hot Load),
DO NOT PUSHloaded into once fired (or new) Remington Brass
Remington 7.5 small rifle benchrest primers
These are loaded mag length - 2.250" + or –
In good air (very lite wind) my CR6724 will hold 1/2 MOA (10 shot groups) out to 800 yards IF I do my part. A good 24" stainless-steel 1/9 barrel should do fairly well w/ the 77grn. SMKs as long as your velocity is on the high end.
