    223/556 or 9mm ?
    hurlburt808 h on May 5, 2018
    BEST ANSWER: I bought this lower and am very pleased with it! It is a 2.23/5.56 that can be converted to a 9mm with a 9mm upper and a 9mm adaptor block to convert the mag reciever!
    Is this compatible with Aero precision uppers? Specifically M4E1 upper?
    Ben H on Feb 27, 2019
    BEST ANSWER: Yes sir it is. 100% in every possible way.
    Is the mag release ambidextrous as well?
    Ray M on Sep 16, 2018
    BEST ANSWER: No, just the safety is ambidexterous.
    7.62x39 will this lower take magazines for 7.62x39 and will it work with a 7.62x39 upper?
    Justin W on Feb 16, 2019
    BEST ANSWER: Yes it will. But it won't take AK type magazines. You'll need buy AR 7.62x39 magazines. I prefer the 10rd/15rd mags. Your upper must be complete with the proper bolt assembly.
    Will this work with a 300 blackout?
    Mike D on Oct 4, 2018
    BEST ANSWER: Yes it will
    So its multi caliber obviously but will it take mags for my 6.8spc build that I am working on?
    BluesClues on Jun 22, 2018
    BEST ANSWER: Yes it will take the 6.8spc mags.
    What trigger does this lower run?
    RON C on Dec 27, 2018
    BEST ANSWER: As the description for the lower states... “Class 2
    Polished Nickel coated fire control group”
    All of my complete lowers are PSA either blemished or not and some I have put in POF triggers but not this one.
    Will this fit the 224 Valkyrie Upper?
    Charlie L on Oct 24, 2018
    BEST ANSWER: Yes, we have used it on 224 Valkyrie, 450 Bushmaster and 458 SOCOM
    Can this be used with your complete PSA 16" .22 LR 1:16 Nitride 15" Lightweight M-Lok Upper With BCG & CH ?
    William J on Feb 10, 2019
    BEST ANSWER: I think yes--but you will need 22 caliber conversion mags because of the larger magwell on this lower
    Will this work with a psa 18 inch barrel with a rifle gas system?
    danny on Jan 6, 2019
    BEST ANSWER: Yes it will, that's exactly what I am using
    Does this complete lower unit have the Enhanced Polished Fire Control Group installed and is the stock the Magpul CTR stock?
    Jan H on Jun 4, 2019
    What 9mm adapter do I need to purchase to chamber my glock magizines?
    Patrick on Jan 14, 2019
    What is the best complete upper to pair with this lower ? Looking for more customizable barrels!
    A R on Dec 29, 2018
    I was watching a video where the guy had a PSA 2.23 SBR and swapped a PSA 7.62 x 39 SBR upper onto his lower using C Defense mags. Is this possible using this lower?
    RON C on Dec 27, 2018
    Will this fit a 6.8 Spc magazine?

    Fantastic setup, especially for my fellow left handers. Im purchasing a second one very soon.
    I purchased this lower about 8 months ago.
    The Ambi safety, EPT trigger and 9mm compatability caught my eye.

    When it arrived, it fit tight to my 16" PSA upper. No scratches or blems. Pristine condition.
    The safety is perfect for my left thumb.
    The trigger is more crisp than standard mil-spec. Not a major difference, but it feels better and I like the nickle colored trigger 😇

    Id recommend this lower to anyone looking, especially those weighing $179.99 vs. $400-$1200 dollar ambidextrious lowers.The features you get on this are more than enough for lefties, bar the 1 modification I made below.

    -Botach Ambi Magazine Release.
    This is a screw-in install that takes 5 minutes if done properly, and gives full ambi magazine control, which is the important thing missing from most ambi lowers. Its $20 online. It works flawlessly. My ambi build felt complete once I added it.

    Great product
    Is what it is supposed to be. Great quality and fits nicely. Throw an upper on, lube, and hit the range.

    Happy!
    I have been very satisfied with all of the products from PSA. My AR-15 from PSA has fired 300 rounds beautifully with no issues.

    My first AR build. First but certainly not my last with PSA!
    Very first AR, bought it in 4 parts. This lower is awesome. Only issue is a little bit of play with stock and upper, ambidextrous safety rubs my palm when activated. Other than that this thing is fantastic. Great quality at an awesome price. Live in NC and the process was painless with FFL. Quick delivery too!
    Arrived much quicker than I expected.
    All put together. Time to enjoy. Quality build

    Great lower!
    Great lower. I’m extremely pleased with the quality (as expected). Can’t wait to take it back out to the range.
    Both upper and lower purchased from PSA.

    Plenty of bank for your buck
    Good trigger, only problem was the takedown pins were improperly installed causing them to come out completely upon initial inspection
