Ok I have a serious question I have a 2000.00 dollar budget and was wondering what the best long range ar type rifle I could buy. I'm looking at shooting distances anywhere from 400-1000 yards. Any advice for me out there. If at type rifle is out of the picture what do you all think as far as tactical rifle out there are best
First off, in the .223 realm, there are a few rifle components which make it better suited to do this kind of shooting, but none are really GOOD for it. Not compared to bigger calibers.
Gunslinger, IBMikey, and Mk41 are much more on track. I'd build one, and it would NOT cost 2K.
Barrel; as was stated, Kreiger or Les Baer. Just tep right up to a 22-24" barrel, which is where the maximum pressures are developed and retained. You will need EVERY ft lb of energy to push that little lead tip along.
As to upper, and lower? Neither matters in the least. I swear. It could be a complete junkyard dog, so long as it lines up and cycles ammo thru it, that is all that matters.
Now, add a trigger, and as was prescribed, a Giselle, or a 2 stage from RRA are good.
You are on to ammo. And, for stepping past 600yds, you are going to need to find what your barrel likes. Plain and simple, if it likes Wolf ammo best?? That is what you run with. If it likes Hornady, or Black hills? Then run with that. Let it be known, your AR will become a single shot rifle, because they do not cycle with 80gr ammo; it is too long for the magazine. You need to hand feed the rifle. (That is why I said nothing about a piston system, or DI preference. It's a moot point, so go DI for cheap. As cheap as possible in fact.)
The optic; that might set you back near 2K alone for the real thing. You CAN get away with a good 6x24 or so. I wish I was kidding, but I am not. No AR specific scope is meant for this kind of shooting.
By the time you do all this, you could have bought a real life bolt rifle that can do this right out of the box for around $500, and spent the other $1500 on the necessary optic. (And, made the rifle throw stuff like .243 or larger to get the job done much more reliably.)
