    I ordered a skeletonized AR 308 from these guys a while back and after the build wound up being my favorite gun. it was a raw deburred finish, i personally loved the tooling marks so i ordered up its little brother, skeletonized ar 15 same way, deburred tooling marks. i received it faster than i thought and as always the craftsmanship did not disappoint, slapped in the jig and away we go.
    Dan, thank you for your help and your amazing customer service, i hear back from these guys usually within minutes, which is unusual, i get excited when its by the next day.

    Was at my door in 2-3 days after ordering. The lower was machined well and the finish on the bead blasting was even. Ill definitely be coming back for more

    This is the most bad ass 80% lower out on the market right now. The design is beautiful and everything I’ve installed on it works flawlessly! I will definitely be buying more before the democrats ruin it for us!

    If they 6 stars, I’d give it to them. Awesome lower. Perfect fit and function. I’ll be buying more for sure!

    It’s a great lower and clearly see the awesome workmanship! I originally got this for my lightweight AR15, but after drilling and milling the FCG pocket I weighed it and it weighs the same as a standard 7075 T6 (8.0 oz) so used it to build another.

      That’s a great build Anthony! And we’re sorry that the Skeletonized AR Lower didn’t come in lighter for your LW build. We’ve done a few more things to make it lighter such as milling a hole thru the grip mount, and building/offering an Ultra-LW version. We also cut the FCG pockets to the M4/M16 pattern which removes more material in the rear of the pocket so this allows us to get under 7 oz on the Ultra-LW. We’re still debating an Ultra-LW AR Upper.

    This is the 4th one I’ve purchased and the beauty and precision is second to none!
