  1. Great lower to offset the weight of a piston upper. 5 Star Review

    Posted by on May 22nd 2017

    Ordered mine a couple years ago. Threw a adams arms piston upper on it. I didn't weigh it but I tried that upper on a stag lower then the GWACS lower, you could feel the difference.

    Love the trigger in this lower. Way better than most factory triggers. Fit is tight to uppers but that's ok. No wriggle room equals accuracy.

    I just did a carbine course this last weekend and the platform as a whole performed flawlessly but that poly lower made a difference totting it around all day. Anyone that has dragged around a rifle for any amount of time knows that every ounce makes a difference. This lower makes a big difference. Had zero issues with the lower. It was comfortable, shorter stock means you can stay tucked in a bit tighter and come up on target quicker. Definitely prefer it to adjustable stock set ups.

    I highly recommend this lower to anyone looking for a light weight, durable, alternative.

  2. Complete Satisfaction 5 Star Review

    Took FDE lower to Appleseed Project in Norman On April 15-16. Performed flawlessly, attracted some attention on the line. I believe it won you at least two new customers.

  3. Tough as Nails - Light as a Feather 5 Star Review

    Posted by on Sep 15th 2016

    I have two ( black and FDE ). The black came into the family several years back, and has endured years of hard use. Still going strong.

    The FDE is new, and I am building a pencil barrel, Titanium rich 14.5 inch pack rifle that I think will scale WELL under 6 lbs.

    Buy without reservation.

  4. As always an outstanding product! 5 Star Review

    Posted by on Jan 11th 2016

    Once again I was not disappointed in my lowers. GWACS is my go to for lowers!

    I just wish they offered one with a trigger guard for winter shooting.

  5. FDE vs: Coyote Tan, Really? 3 Star Review

    Posted by on Jul 25th 2015

    I love your lowers. I have 4 of them. I was excited to see the Coyote tan come into production. Even though it cost more, to me it was going to be worth it. But once I got it in hand it isn't a true coyote tan. It is barely a little shade different from the FDE. I would call it a mix-up in the color formulation but it is not coyote tan. Really you can barely see the difference. I am keeping it because it functions well. But I am disappointed.

  6. Best Kept AR Lower Secret 5 Star Review

    Posted by on Mar 22nd 2015

    I had never heard of this lower until I saw a torture test video on InRange on full30.com. I was impressed and I thought I'd give it a try for a light weight build. I ran about 180 rounds through the rifle (Palmetto State Armory stainless pencil barrel upper and FDE Vav-15 lower) this weekend at a competition and it ran flawlessly.

    The length of pull is perfect for me and the trigger is comparable to the one in my Colt 6920. The rifle I built comes in at just about a pound lighter than my stock 6920.

    This lower goes on tight, so be prepared for that, I need a punch and hammer to install the rear pin. I've been told it breaks in over time. There is absolutely no play between the upper and lower though, so I don't mind the tight fit.

    I would recommend this lower.

  7. The perfect lower for a featherweight build! 4 Star Review

    Posted by on Oct 2nd 2014

    Some cosmetic finish issues are the only thing preventing me from rating this lower 5 stars. Some of my mould lines were very rough and the rear of the stock was not trimmed in a flat plain (waivy). Functionality is excellent, however.

    My purpose in buying this is for an ultra-light build and it is lighter than a fully fitted Ballios light lower with all but the most minimal flimsy stock. or even a fully fitted Magtech lower without very the substitution of very expensive titanium lower parts . However, there is nothing flimsy about it. This lower is thick where it needs to be and is not like other polymer lowers that have to be dimentionally compatable. There is no way this is going to break in the area corresponding to the rear reciever ring on a standard shaped lower.

    It fights snugly to my upper. The trigger is an excellent single stage trigger. New and dry it was slightly creepy with a pull weight of about 4lb 9.5oz. Without lubricating it, I boosted it 5 times with light finger pressure behind the trigger, 5 times with moderate finger pressure behind the hammer, dry fired 100 times, boosted again 5 times with a finger behind the trigger, 5 times with a finger behind the hammer, and dry fired another 200. The sear engagement surfaces looked smooth and uniform and the creep was gone. After lubricating, the pull weight was 4lb 4 oz and very clean and smooth! This has saved me buying an expensive aftermarket trigger. I see another reviewer hates the trigger and I don't see how we could have possibly reveiwed the same trigger. I know triggers too--I usually use a Geissele High Speed.

    As I mentioned before the shape is a little different that a conventional lower. The trigger reach is a little longer but for my long fingers this is a plus. Also, unlike a conventional lower, I can flick the safety back to safe with my thumb without shifting my grip. For me, this eliminates the need for an ambidexterous safety. Again, I think it is because the hand is slightly further back.

    The complete populated lower weights about 1lb 12oz. I dropped about half an ounce with the GWACS aluminum pin kit, about 1.9oz taking out the slide weights from the buffer and plan on saving another 1 oz with a titainum-core safety, aluminum mag release, and aluminum buffer retainer. I was shocked that the very nice metal buttplate and screws weighted about 2.6oz! For most builds this would be a plus but it is a minus for me. I will be replacing with a polymer A2 style buttplate and nylon screws. I bet I can save another 1-1.5oz.

    The only other issue I encountered was a weak safety detent until I stretched the spring a bit. I suspect the sping hole may have been drilled a shade too deep. If this is an issue again, I can drop something in there to shim the spring.

    I ordered a pully poulated lower with the overgrip and my FFL got a stripped lower. GWACS quickly Fed EXed the missing items, even offered to install for me. They comped me a free aluminum pin kit. GWACS is a stand-up company that makes things right of there is a problem.

    I would not hesitate to buy one of these again or recommend one to a friend.

  9. Great Product 5 Star Review

    Posted by on Jun 30th 2014

    I received my GWACS Armory fully populated lower last week. After function testing I attached an upper and spent a weekend at the range with it. It performs perfectly. The fit and finish were better than expected, with absolutely no excess flashing to remove and only a slightly visible seam on the front outside surface of the mag well.

    The lower is Flat Dark Earth and it matches VERY closely to other vendors' FDE magazines, rails, accessories.

    If there is one negative thing about the design of the lower is the inability to use various sling adapters due to there not being a receiver end plate. An integrated QD stud or just an embedded sling loop behind the pistol grip would be perfect.

    I was concerned about the fixed length of the stock, but the length of pull is perfect for me, so no need for a butt pad or shortening the stock.

    Overall I am extremely happy with my new lower! It looks great and is a bit unique. I will definitely consider another for future builds.
