Shield Arms Folding Lower Receiver

Introducing the world’s first folding AR-15 lower receiver – no adapter required.

Bigfork, MT, October 29, 2018 – Shield Arms

The Shield Arms Folding Lower Receiver (FLR) is a patent-pending billet lower receiver with a folding stock mechanism machined and built directly into the receiver, allowing the stock or pistol brace to fold without the need of an aftermarket folding stock adapter. No installation. No tools. Just open the box, fold, and go.

The Shield Arms FLR is precision-machined from 7075 billet aluminum and is designed and manufactured in the U.S. The FLR ships as a stripped lower receiver with included buffer. The folding stock mechanism is preinstalled and accepts any standard aftermarket buffer tube. To complete the lower receiver, simply use a standard lower parts kit, and customize the Shield Arms FLR to your preference.

Additionally, the Shield Arms FLR uses a standard bolt carrier group and does not modify the carrier in any way, nor does it require any additional parts to function properly. As an added advantage, due to the folding mechanism being machined directly into the receiver, the overall length of the lower receiver is increased by only 5/8”, less than half the length of some popular aftermarket adapters.

The Shield Arms Folding Lower Receiver will be available for order soon in 9mm with an MSRP of $399.99. Additionally, Shield Arms will be licensing the FLR to other manufacturers – interested parties should contact licensing@shieldarms.com.

Shield Arms SA-9

The Shield Arms SA-9 is a complete AR-15 style 9mm weapon system built on the FLR. The select fire version of the SA-9 was recently selected by the US Army to participate in the Sub Compact Weapon Prototype Opportunity.

The pistol version of the SA-9 equipped with an SB Tactical SBA3 pistol brace will be available for order soon with an expected MSRP of $1,499.99.

    Now this is cool.

    Looking forward to a 5.56 version down the road.

    Any indication of how much weight this adds vs a conventional lower?

  2. jbgleason says:

    What happens if it is fired with the stock folded?

  3. jbgleason says:

    Will it fire with the stock folded?

    • P.J. says:

      Given the buffer tube is folded with the stock I’d wager the answer is “no”.

      • jbgleason says:

        Unless it folds the BCG with it, then everything is in place to fire a round. The question is really, “will firing a single round with the stock folded damage the receiver?”

    • Vic Toree says:

      If it functions similarly to the LAW folder (and it looks like it would), it would probably fire once, but obviously wouldn’t cycle beyond that. Very much not recommended.

    It’s an AR platform with a buffer system….
