    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.

    Looks cool- how does it shoot? Any issues with cheek weld and the scope? You may want to have a look at a contraption made by Larue Tactical called the RISR- its a cheek riser that will reciprocate backwards on an internal spring when you need to use your charging handle, and it is designed for MAGPUL stocks.

    Only had it out a few times as of yet,but it shoots very well. No issues with the scope.

    I gotta say though... that contraption from Larue looks silly as hell... lol. "Reciprocating cheek riser"? I've seen a lot of LPVOs on a lot of guns since they got popular. This may be my first try at one, but I've never seen a single one with that contraption on it...

    Nice Build. I built a 16 incher on aero receivers and I'm also using the PA 1-8 with ACSS.

    Coronacation has me working on my first AR10 builds as well.

    Ordered an Aero upper & JP FMOS carrier so far. Decided they won't be turning into the same gun, so I suppose my Trumpbux will be going towards 2 AR10s.

    It never ends.

    I have 2 of them- one on my Barnes Precision carbine I use in multi-gun competition, and one on my Larue OBR. I found that they work exactly as designed. We also had them on some of our MK12 and SR25 rifles in the mil. I believe the SAS guy who fought it out with the terrorists in the mall in Kenya had one on his M4 as well.

    Barrett Rec10 with Razor HD Gen II. I compiled a list of the parts, and it would have been $300ish more to build to the same spec. 20200106_172632.jpg

    It is always nice to be able to know what you want and then build it exactly as you pictured it.
