i have be trying to build a collection that will cover everything out to 750 meters, i think i just about got what i need. i am going to upgrade the components on the ARs when i get the money. lets me know what you guys think. thanks

For what it,s worth in my opino (you got it covered realll good)

I am assuming your 700 is a .308.  I think what you've got would do nicely.

If I was doing it, and this is just personal preference, I would have gone this way:

M4(gery)with good optic like an Aimpoint, easily effective in the 0-300 range.

20" AR10A4 with good moderate power scope, say a Leupold M1 in 3.5 - 10x.  Easily effective to the full range you are targeting.

Remington 700 type in a magnum load - 338, one of the 'win mags', etc.  Just a little more serious knock-down power for the situations where the bolt gun would actually be employed.

Also, not shown here, get yourself a good 12 gauge and a solid .45 (Sig/HK/1911/etc.) to round out the collection for maximum versatility.

Again, these are just my opinions, take it for what its worth![:D]

 Nice stuff!
 I think you have everything covered without the 20in. in the center.
 I have about the same setup but I'm selling my 20in. and my 700, Hopeing to replace them with an AR-10

i didnt really know about the AR10 before i bought my pss, or i would have went that way.
i do have a nice 18" rem 870 also, and a sig 220 and 229 to round out the whole shabang.
i took a buck at about 400 meters(laser range finder) with my pss last year, resting on a stump. i might sell my pss eventually for a AR10 but i sure do like the pss. are the AR10s as accurate?
im definetly going to upgrade to a aimpoint on the 16" and a trijicon on the 20" when i get the money. thanks for your replies

Great looking arsenal gootmatcher. The AR setups are very similar to mine. The next long gun I plan to ad is a Savage 10FP-LE1 20" 7.62x51mm with their new Accu-trigger.

I would get rid of the POS M4. and put an aimpoint on the 20"er and a FSB. 18" barreled 870 would replace the joke carbine. To me, carbine is english for inutil.
