Phase 5 Weapon Systems® AR-15 Ejection Port Cover – "Surprise Asshole" – EPC-SURPRISE
The Phase 5 Weapon Systems® AR-15 Ejection Port Cover (EPC-SURPRISE) is a rugged, laser-engraved component designed to add a distinct splash of custom personality and tactical humor to your rifle assembly. Built from standard, military-specification stamped steel, this dust cover utilizes a dual-position laser marking process. While the rifle is in a cold status with the dust cover closed, it presents a clean, sleek matte black appearance. The moment the charging handle is racked or the first round is fired, the door drops open to reveal a crisp, high-visibility graphic text engraving: "SURPRISE ASSHOLE" facing outward to anyone downrange.
Machined to strict mil-spec tolerances, the EPC-SURPRISE (813318020246) is a universal, drop-in replacement for any standard AR-15, M4, or M16 platform upper receiver (including popular 5.56 NATO, .223 Remington, and .300 Blackout variants). The exterior shell is treated with a heavy-duty, corrosion-resistant parkerized finish that deflects aggressive solvent wear, high-heat carbon scaling, and environmental moisture. Unlike cheap printed designs that flake off or fade over time, Phase 5's specialized laser engraving process physically alters the surface layer of the metal, ensuring the text remains razor-sharp and legible through thousands of hard slide-cycling sequences and abrasive range cleanings.
Includes: (1) Phase 5 Laser-Engraved Ejection Port Cover Door ("Surprise Asshole").
*Please Note: This is the bare laser-engraved dust cover door only. It does NOT include the hinge rod, spring, or c-clip retainer. It is designed to drop onto your existing upper hardware or pair with a factory completion kit.
