Key Features & Benefits
MIL-SPEC fitment: Manufactured to standard AR-15 ejection port door dimensions for reliable, tool-free installation in most AR-15 upper receivers. Palmetto State Armory
Durable material & finish: Made from steel with a black parkerized finish for corrosion resistance, low reflectivity, and a factory look that blends with common parkerized or anodized uppers. Magnolia Defense
3.10" overall length: Sized to match standard AR-15 port openings and ensure proper closure and dust protection when the rifle is not in use. friscoguns.com
Laser engraving: Bold permanent laser engraving — the “Surprise Asshole!!” artwork is crisp, long-lasting, and stands out against the parkerized background. Phase5 WSI+1
Simple swap upgrade: Includes the dust cover only (no hinge pin or springs/hardware), so it’s perfect for users who already have the standard installation hardware and want a fast, affordable cosmetic change. Confirm whether your current hinge pin and spring hardware are reusable before installation. Palmetto State Armory
Detailed Specifications
Installation & Compatibility Notes
This ejection port door is intended as a direct replacement on AR-15 uppers that accept standard MIL-SPEC dust covers. Installation normally requires removing the upper receiver’s hinge pin and transferring or replacing the spring/hardware. If you’re not comfortable performing this small armorer task, a qualified gunsmith can install it quickly. Palmetto State Armory+1
Because the product ships as the dust cover only, check your parts kit before ordering to ensure you have the hinge pin and spring available or are prepared to purchase them separately. Buds Gun Shop
Use Cases & Who Should Buy
Custom builders & finishers: Anyone finishing a custom AR build who wants a distinctive, tongue-in-cheek port door. Phase5 WSI
Collectors & range rigs: Great for display rifles, range toys, or builds where personality and individuality matter.
Gift or gag upgrade: A quick, inexpensive way to add humor to a project or to surprise a like-minded shooting friend (be mindful of audiences and environments where profanity may be inappropriate).
Legal & Etiquette Considerations
The engraved text contains profanity. Consider where and how the firearm will be used or displayed — some ranges, clubs, retailers, or jurisdictions may have rules or preferences about visible language on firearms. Always comply with local laws, range rules, and range etiquette when bringing customized firearms to public venues. Phase5 WSI
