My very first build! It took me nearly 5 months to collect all of the parts because of life and .308s aren’t cheap. But in less than two weeks I assembled everything with only minor issues, dialed it in and took the nicest buck of my life from nearly 350 yards.

Seekins Precision 60 degree ambi selector

    Great deer congrats! Nice looking stick too.

  • Devil_Doc

    Is this in WA? Nice muley…

  • Joel.k

    AR15? It should say AR10…

    • JSmath

      Guess I might as well be “that guy”: If we’re going to get technical, it should say DPMS 308. πŸ˜‰

    • Anonymoose

      “AR10” is a trademark of Armalite, Incorporated, and the AR-10B and A (which came after the B because no one wanted to buy their stupid proprietary mangled M14 mags) are more proprietary than all other .308 ARs. .308 ARs have less in common with the original AR10 of the 1950s and 60s than they do with the AR-15A2. The first .308 AR15 to come out was the SR-25, then Armalite released a semi-affordable copy of that concept as the “AR-10B.” Then Bushmaster (BAR-10/RRA LAR-8), DPMS (LR-308, using the increasing common SR-25/M110 mags) and others got into the game (almost all going off of DPMS’s pattern).

      • ostiariusalpha

        And the original ArmaLite sold Colt a prototype for an AR-10A that is more like a GII frame than anything the present ArmaLite makes.

        • Anonymoose

          According to Armalite’s website, in the mid-90s, they took a block of aluminum and milled it out to fit an SR-25 upper and a modified M14 mag, and that became the basis AR-10B. The currently commercially-available AR-10A is just an AR-10B that uses SR-25/DPMS mags. Did anyone besides Armalite, Novekse (discontinued years ago), and Mega (optional on the MATEN) ever make a lower that used AR-10B mags?

          • ostiariusalpha

            No, that was about it. It was a peculiar set of circumstances that led to the AR-10B magwell, having to do with the limitations that the 1996 AWB imposed on the kinds of newly manufactured magazines that could be produced. Since the M14 mags were only alterations of pre-existing magazines they got around those capacity limits. When the AWB sunsetted there wasn’t much reason to stay with the AR-10B design, and ArmaLite transitioned away from it slowly as this fact became more clear to them.

  • manBear

    Wow stellar buck … Wish I could use a cool AR for deer in Indiana πŸ™

    • Anonymoose

      As an Ohioan, I share your pain. I think you might be able to use a .45ACP or 10mm AR, but mags would be a pain, and you’d have to be very precise.

      • Robert Griffith

        No. .450 Marlin is not allowed in Indiana. Case length must be between 1.6 and 1.8 inches to be legal. .450 Marlin case is 2.1 inches.

        • Anonymoose

          Man, that sucks. At least we’re allowed late-1800s rifle cartridges like .38-55, .45-70, and .50-110 (as if anyone makes .50-110 rifles or ammo anymore, besides Grizzly Cartridge).

          • Robert Griffith

            It’s not so horrible. It’s an improvement over the time when
            we were only allowed to use shotguns to harvest deer. We Hoosiers have many more options now for deer hunting.

          • Robert Griffith

            One enterprising Hoosier has developed a new caliber known as .358 Hoosier that complies with the new regulations for legal calibers. It is basically a .308 case trimmed back to the limit and a .358 bullet. Look it up if you’re interested.

        • Justin

          Growing up in Indiana in the 80s I was only allowed to use shotguns for deer, so I feel your pain. I didn’t know the law had changed though, so it is a little better than my day at least.

          • Robert Griffith

            Governor Daniels signed the changes into law back in 2012.

      • AHol

        Would a 6.8 spc work in Ohio? It is a great round for deer and can be built off the basic AR platform.

        • Anonymoose

          Nope. We were given a list of acceptable straight-walled “pistol cartridges” allowed in our durr rofls. Your best bet is probably .45-70, .38-55, or a Magnum or .45 Long Colt carbine if you want to hunt durr here with a rofl.

    • Jason Guhl

      You can! Its called .450 Bushmaster. It is legal.

    • Keith Brockmiller

      You could use this one as it’s a 308. Unless Indiana bans “scary black rifles” πŸ˜‰

  • INFI

    Awesome job man! On the rifle and the buck!

  • Kivaari

    Nice build. Nice deer.

  • PeterK

    That is inspiring. Someday I’ll build an AR that cool. Need to get out of school and maybe out of debt first, though, heh.

    • Jsim

      You should do what I’m doing since I’m still in school also. Just about every other month I buy a part this way it doesn’t seem like I’m spending so much money and I also don’t need to skip any meals lol

    • You can do it Peter. Shop around on line for the parts.

  • Rusty S.

    Excellent Muley! Great job! Are you going to do a shoulder mount or European?

  • Bj

    I helped mount up that scipe. Nice you got a deer with him.

  • Abram

    Nice setup! The folks and facility at West Coast Armory are outstanding. Specifically the Factoria location,

  • Mc Cain

    He shoots…he scores! Nice post.

    Come on guys, one of the biggest issues we face in the “modern sporting rifle” arena, is accuracy in our terminology. And this article just laid waste to that. it is important to understand that the .308/7.62x51mm AR rifle is NOT an AR-15 it is an AR-10. This is a different rifle entirely. It is designed similarly, but other than the handful of components in the receiver, everything else does not interchange. Many may consider this nit picking but it is the equivalent of comparing a small block car engine to a big block and then proclaiming no difference. These ARE two different rifles and should never be confused with each other.

    • SacLamb

    • go4it

      I just call mine an AR-308 …. No one seems to care what I call it – the “308” identifies it clearly enough. What matters is that it exists. Well, “they”; I have 2.

      I feel sorry for the time gap in the author’s article. I had all my parts delivered in about 3 days; took about 90 minutes each to assemble them …..

  • go4it

    A well-placed shot from an AR-15 – where allowed by local laws – should snare most deer. A shot from a .308 leaves no doubt … and a little more margin for error on placement. A “PSP” shot (pointed soft-point) from a .308 is likt hitting one with a bolt of lightning …

    Some states seem to be getting *much* more unfriendly toward “rifles” used for hunting. All part of the anti-gun screams, I suspect. Their logic? If they can’t be banned or siezed, then just render ’em useless. Hard – they apparently think – to justify paying $900 – $2,000 just to punch holes in paper!

  • I have built seven AR’s so far and machined the lowers which I did on the Sherline mill. I don’t recommend the Sherline for this job because when you get to the bottom of the lower, there’s always the chance of cutting the trigger hole to much; which I did at least twice. With a thin piece of aluminum and some JB Weld, I was able to fix the problem but I still think it was sloppy work on my part.

    Cool guy toy. Weapon assembled by a garage tinkerer. Followed all the arfcom fads. You’ll get lots of high-fives there.
