Aero Precision Launches Gen 2 AR Lower Receivers

Aero Precision has launched their second generation of AR lower receivers. Aero still starts from 7075 forgings, but has taken the time to add features many shooters would enjoy. Specifically, the magazine well has been flared, the selector switch is a new set of pictograms (and compatible with Battle Arms Development’s short-throw safety/selectors), and includes a tensioning set screw.

The new receivers are available in both standard and ambidextrous format. The ambi receivers include the PDQ bolt catch/release.


Details from Aero Precision’s Website (where both standard and ambi are available):


Our AR15 Gen 2 Stripped Lower Receiver is the perfect base for your custom AR15 build. Machined to mil-spec dimensions, our lowers work with standard AR15 components and ensure the highest quality with a correct component interface.

Gen 2 Improvements:

  • Upper Tension Screw – Allows users to fine tune the fit of the upper and lower receiver through the use of a nylon tipped tensioning set screw inserted in the grip tang of the lower receiver. This provides a tight fit with any standard AR15 upper receiver.
  • Increased Magwell Flare – Allows for easier insertion of magazines and provides a sleeker look.

Standard Features:

  • Platform: AR15
  • Material: Machined from 7075-T6 forged aluminum
  • Coating: Matte black hard-coat anodized Mil 8625 Type 3 Class 2
  • Markings: “Cal Multi”
  • Works with standard AR15 components and magazines
  • Rear takedown pin detent hole is threaded for a 4-40 set screw
  • Weight: 8.35oz


  • Stripped AR15 Lower Receiver, Gen 2
  • Nylon tipped tensioning set screw

    I was really hoping that someone would come out with an AR lower that was just slightly different than every other AR lower. /s

    HOLY COW! I just looked at the price. Only $90? My LGS sells no-name crap lowers for that much. This thing is a great deal. I was totes expecting to see a $300 price tag, and then to whine about it.

    This has some great features for the price.

      I own one of their gen 1 lowers, and I am impressed by the quality for sure. I may never buy another brand again.

      My LGS sells Anderson lowers for $50 and I’ve seen them for about that price around a lot. I think your LGS might be a gouger.

      • dan citizen

        They aren’t big into stripped lowers, mostly they sell ones that someone ordered and didn’t want.

    • Rex Krom

      I have there gen 1 upper and lower. Really nice product. I got the stripped lower from my LGS protection first in spokane WA for $60 I think.

      totes expecting

      No. You stop it right now. 🙂

    I really like that ambi-lower, but I don’t see why it demands a $75 premium over the standard one. The machining and parts required don’t seem to add up.

    • aerogerald

      PDQ wants 60 bucks for their (admittedly clever, but still pricey) bolt release, aero’s markup is really on 15 bucks for the machining, which i find to be very reasonable for the work done. Still, as a lefty, at 75 bucks, I’m going to reach with my trigger finger instead.

  • whskee

    Aero has certainly been on their game for quality at fair prices. I really like where they went with the M4E1/M5E1 builds. I’m looking at either building a M5E1 or going with the DPMS GII. There’s a lot of extra satisfaction to piecing it together yourself though.

  • Nathan, on the first paragraph you put 7076 instead of 7075 Al alloy.

      Throw him to the lions!

    I’d like to see a review on that tensioning screw. Also, what’s going on with that paddle on the right side of the receiver? Is that an ambi-bolt release? I’ve fallen in love with the Phase 5 EBRV2 and don’t plan on using anything else.

    • Cymond

      That’s the Teal Blue PDQ ambi bolt release/lock (lift with your trigger finger to lock the bolt open while pulling the charging handle).

      • Grindstone50k

        Thanks for the link. I haven’t taken out a bolt stop myself before, but putting in one with a basic set of punches and a lower block is pretty easy.

  • Zachary marrs

    Its too bad they didn’t go back to the old rollmark, but whatever, I’ll survive

  • Anon

    They are really great for quality and neat products… except when they aren’t great for quality. and when they aren’t you might as well toss the part and buy something else considering the amount of time it takes to get them to contact you about an issue. I tried for weeks both phone and email. no response ever. Never able to get through

  • jeff k

    wow i really like the tension screw,. no more accuwedge lol . and the short throw safety is great . alot of features for the price. im getting one for sure
    ps. for anyone who doesnt know . aero makes the lowers for a lot of manufaturers including palmetto state, and saa plus many others . they are a very good name brand lower

  • John Daniels

    Seeing a lower that comes out of the factory with a PDQ makes me very happy.
