The RL556v3 80% AR-15 Lower is constructed from the same reinforced material that all current-production, off-the-shelf polymer firearms are built from. Polymer80 took the time to test, re-develop, and test again, their polymer lowers until they achieved a unit capable of handling thousands of rounds without failure.

It features reinforcements based on real testing to guarantee reliability. Polymer80 beefed up the buffer tube ring, reinforced the receiver with a solid core, added ribbing across the entire top surface, and developed a no-thread pistol grip mount. Last, the mag well has been stiffened, all while retaining a featherweight profile.

Polymer 80 is known for designing 80% receivers and jigs, so you can build your own Glock style handgun or AR-15 right in your garage. They have grown in popularity so fast that they are now offering their own completion kits with all the internal parts you need to finish a build. Whether you want to build a handgun or rifle, P80 has you covered.
