A friend of mine made a request. As a fan of Bushmaster, etc., he has been somewhat persuaded that he should upgrade. But he said he wants to upgrade to “one and only one battlefield rifle” which is:
o durable
o reliable
o accurate long range shooter w/ Nightforce scope
o lightweight
o 16 inch barrel
o green laser
I won’t post my horrifyingly long response. But you probably get the idea…
Anything to the left of the “chart” would be a dramatic upgrade form BM. Colt 6920s are going for 1100 bucks these days online and is a steal. Mine would be from DD, BCM or Noveske 14.5 or 16 in barrel, in a middy configuration with a government or light weight profile, 12.0 lite rail, an aimpoint H-1 and a light. Get ammo, quality mags and training, and he’ll be GTG.
SCAR

As for a green laser I’ve been looking at this unit. http://www.laserlyte.com/Laser_Gun_Sights/K-15/K-15.html
If a SCAR is out of his budget then what RogerinTPA posted is good advice. DD and BCM are hard to beat right now. My “goto” AR is a BCM.
.
I own Colts, LMTs, a BCM middy and various frankenguns with lots of RRA, Bushmaster, Sabre, Mega and CMT parts so I think I’ve seen and have experience with a wide array of ARs over the years.
Recently I had a change to check out va_dingers Daniel Defense DDM4 v1 and I was so impressed I ordered on the very next day. Specs, quality, attention to detail are at least equal to, and in many ways exceed, the big names on the chart.
Like I said, I was so impressed I ordered one after spending some time with va_dinger’s. It hasen’t arrived yet but I have a feeling that once it gets here it will be my primary, go-to, carbine. Have your buddy check out Daniel Defense.
One and only? My answer won’t be horrifyingly long (for once):
SCAR 17.
AC
Battlefield rifle huh, then I guess that cancels out anything in 5.56 flavor. 
Is the discussion here limited to 5.56/7.62, it would make sense that it would be if ammo availability is one of the concerns.
To me the lightweight requirement makes it hard for a 7.62 rifle to qualify.
I would think a high quality 16" AR barrel on a good rifle would get 500 or 600 yards fairly reliably. Does that meet the long range requirements?
I chose a Grendel for this role but I don’t need a “battlefield rifle” so I was willing to give up a little on ammo availability, something I wouldn’t do if I wanted a battlefield gun.
Does he want to shoot 1000 yards with it and use it for CQB as well???
My “one and only one” would have to be an SR15. Even though its got propietary parts if you run the gun enough to break those parts then you probably might be looking at just ditching it for a whole new gun by that time.
Either a good AR or maybe the SCAR-17.
Im really digging the new M16A5 though as an all around battle rifle.
WOW:eek:, did not expect that.
I knew I shouldn’t be reading this thread with it’s title…
eta… Why is the green laser a requirement…maybe to kill pink zombies??
StG 58.
I think so, which is why I provided a horrifyingly long response about close, mid-range and long-range rifles.
It is interesting that there are so many recommendations for the SCAR. It’s not that I thought it was not a good gun, but I did not realize it had so much support.
I don’t know, it’s just what he said. Maybe red ones hurt his eyes. 
Or maybe he wants to be able to mark his own position for when his wife brings his lunch by.
KAC SR15E3
HK .308
or
Scar 17’s
Hi-Point Carbine all day…in a very distant 2nd HK 417 (if available)…3rd Scar 17 :sarcastic:
For all you gents that list all these new .308 AR’s…what happens when you run outta ammo and everyone around you is sporting 5.56 blasters on this so called “ultimate battlefield”
A .308 on the battlefield imo will handicap you significantly if you spend any amt. of time in the field or expend a high volume of fire at any one particular engagement. I would not even consider a .308 AR in this role and its still the “niche” AR in my eyes. Besides ammo, the extra weight, recoil, few capacity mags, an overall caliber that is not nearly as proven when operating in an AR platform as a 5.56…etc.
mybad, i thought a battle rifle was described basically as 308…i read that somewhere in here idk…but yeah i would rather use a lighter 556 rifle if its allowed in this scenario…so, mine would be Hi-point carbine in 556 by a long shot, HK 416, SCAR 16 but i would feel damn fine with a DDM4 (carbine gas system :eek:)
The question is, does Hi-Point even make a 5.56mm carbine, or do you just feed the 5.56 through the 9mm??? I know it’s Hi-Point, and they are that awesome, that you don’t even have to use the correct ammo…
But besides the Hi-Point carbine, I’d just go with a quality AR carbine.
