Why Should Your AR Look Just Like Everybody Else s?

Polymer80’s RL556v3 brings all of the Do It Yourself benefits of their original line of 80% AR-15 lower receivers, coupled with a bold new look and functional upgrades that’ll set your AR-15 apart from all the others on the firing line. The RL556v3 has reinforced magwell and extra material around the fire control pocket - adding up an even more robust receiver ready to stand up to the demands of 3-gun competition and other high round-count shooting activities. Of course, like all Polymer80 80% lowers, the integral triggerguard provides an extra measure of structural integrity and strength that adds up to a polymer lower that’s extremely strong.

The RL556v3 also comes with a blank serialization plate on the right-hand side of the receiver for commercial customers who are required to apply a serial number on their custom rifles.

Most noticeable is to the observer is the blocky, aggressive aesthetics of the RL556v3 with its exterior reinforcing panels and crisp, squared-off triggerguard. Sure, good looks aren’t "mission critical" to a rifle, but as long as you can have them, why not?

Returns will not be accepted once the receiver is modified in any way. All warranty issues will be directed to the manufacturer.
