I put together the perfect .308 AR. Now keep in mind, when I say that it's the "perfect.308 AR", I mean it's the perfect one... for me. I was looking to get into a .308 because I wanted the better terminal ballistics of the heavier round. What I didn't really need, was the increased range. This was to be a defensive combat carbine. As it was to be "defensive" in nature, it's not one I would need to reach out long distances, at least not in my area. This could be called a "SHTF" gun if you'd like, because that's it's purpose, but even then, it's meant to be a defensive weapon. I'll not be going on the offense. I'll not be sniping anyone from great distance. I'm not in the Army anymore, and I can't justify that as "self defense", either to myself, or in any court. I just wanted something with a bit more oomph than the 5.56, or should things go really bad, the ability to punch through cover better. I did still want to keep it in as small, and light a package as I could. I wanted a patrol carbine, not a full on sniper rifle. On the other hand, I've seen guys go way too far with the "smaller is better" theory too, building 10" .308 pistols that though probably very fun to play with, would pretty much cut the .308 off at the knees. I tried to make a decent compromise, and I'm pretty happy with the end result. Receivers... Aero Precision with their LPK Barrel... BA Hanson 14" with pin-and-welded Warcomp Rail system... Midwest Industries Scope... Primary Arms 1-8 with the ACSS reticle BUIS... Troy with tritium BCG... Lantac enhanced Charging handle... Raptor Recoil system... JP Captured Trigger... Geissele SSA-E Furniture... Magpul CTR stock, MOE grip, MVG M-LOK Weaponlight... Surefire M300 Scout Light Leftover ambidextrous safety that I can't remember where I got... Leftover scope mount... same deal... just happened to work out well. Anyway, the end result is the rifle is a bit heavier that the typical AR (as expected being a .308) but still very easily carried as a patrol carbine. Going from 16" to 14" was only a 2" loss, but it makes up for the larger .308 receiver, and it really isn't any longer than a 16" 5.56 AR, just a bit heavier. I really like the way I can move with it in hand. I lose some velocity, and power going down to 14", but not as much as going crazy, and doing the full on SBR 10" thing. It still packs a lot more punch than a 5.56. It's very controllable. Not sure if that's because I'm a big dude (6'1" 280) with 28 years of Army experience, or the very effective Warcomp (probably both) but I like it. I really like the ACSS reticle.
