Affordable Ambidextrous AR-15 Lower Receiver

Making the AR-15 friendly for left-handed shooters used to be a tall order.  Thankfully for the southpaws out there, starting a completely ambidextrous lower build has never been easier or more affordable.  This ambidextrous AR-15 lower receiver from Unbranded AR adds a right-side bolt release a a classic forged receiver.  With the addition of a few proprietary parts, you can chamber a round from either side of the gun.

Outside of that, the lower is the same as any other; your favorite parts and accessories will work flawlessly.  Unbranded AR has made sure that this ambidextrous AR-15 lower receiver can accept a wide variety of mil-spec and aftermarket components so you can build this out any way you want.

To make a complete ambi lower receiver, be sure to pick up an ambidextrous magazine catch assembly, and choose from any of the ambidextrous safety selectors we have.  Don’t forget a good trigger and a buffer tube kit!

This lower includes the proprietary components for the right-side bolt release.  These include the bolt release paddle, roll pin, bolt catch spring, and enlarged bolt catch plunger shown.
