Re: AR10 - Buy or Build
What type of shooting- Static prone or bench vs. tactical, CQB style?
Practical Distance- Range of shooting?
Weight and ergonomics of platform?
I have used many variations of the SR-25 or DPMS style 308 AR platforms in the last 20 years. These were mostly working "Battle Rifles". Most with field expedient mods to make it run for the conditions. Only in the past 5 years or so did I have ready access to all the bling that the internet offers.
My all around favorite for a factory or pre-built 308 rat gun is Mark Larue's 18" OBR- I outshot the bolt guns out to 1300 yrds. w/ factory Black Hills 175SMK's. It's light enough for occasional walks through the forest.
But, as I get older and wiser- lazier, weight and ergonomics are more important.
The FBI has been experimenting with faster twist barrels and lighter bonded rounds. Without giving up their secrets, 155gr bonded 308's are staying supersonic out past 1200yrds in faster rifling.
I currently use POF's 14.5" gas gun as my primary 308 precision gun when a bolt gun just won't do. It's light and can be carried around all day- and will keep up with most of its longer barreled cousins. I even use this when most are using M4 SPR's. I pull off the scope and mount a red dot or holographic site. Nobody notices until it goes bang.
