What do King Arthur’s Excalibur, He-Man’s Master Sword, and Lion-O’s Sword of Omens have in common? None of them were chambered in .223 Wylde and came with a full compliment of Magpul add-ons. Those guys may have used their swords to rule their lands, but they damn sure didn’t build ’em themselves. And their haircuts were terrible, but I digress. You’ll complete yours yourself with this build kit.
We get you what you need to build your AR-15 with this kit. Then you finish it off with premium Magpul furniture and hardware. You get a Magpul MOE stock, MOE grip and trigger guard, and MBUS back up sights to complete your build. And the handguard has keymod attachment points running its entire length, so you can mount tac lights, lasers, or whatever else. Plus, the barrel is chambered in .223 Wylde, meaning you can smite and vanquish paper targets with both .223 and 5.56mm NATO. All you need after that are mags and ammo. Get medieval with this kit today!
Your Excali-beast awaits you, sire.
