XTS Oops Kit Replacement For Most Commonly Lost AR15 Parts XTS SPS XP UPC 767820093581
Product Description
The XTS® AR-15 Oops Kit Replacement Small Parts Set (SKU: XTS-SPS-XP / UPC: 767820093581) is an essential bench and range-bag emergency spare parts assortment built for AR-15 builders, armorers, and shooters. Designed to replace the high-tension detents, springs, retainers, and retaining pins most frequently launched or misplaced during lower receiver assembly and field maintenance, this kit prevents a minor lost component from halting a build or range session.
Manufactured to strict Mil-Spec dimensional tolerances, every component in the XTS-SPS-XP is crafted for durability and consistent mechanical engagement. High-tensile spring steel coil springs maintain uniform compression force across thousands of cycles, while precision-turned brass detents provide smooth, gall-free indexing against steel takedown pins and safety selectors. Hardened steel buffer retainers and firing pin retaining pins feature corrosion-resistant protective finishes to withstand carbon fouling, heat, and gun-cleaning solvents.
Packaged in a compact, easily stowed format ideal for a pistol-grip storage core, range bag, or armorer bench organizer, the XTS® Oops Kit supplies duplicate spares of critical small parts across both the upper and lower receiver groups. Whether completing a stripped lower receiver build or staging backup hardware for high-round-count carbine courses, this kit ensures immediate field serviceability.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Compatible with standard Mil-Spec AR-15, M4, and M16 upper and lower receivers. CRITICAL WARNING: Verify spring orientation before installation—the disconnector spring features a wider base coil that MUST press firmly into the disconnector pocket so it does not separate under cyclic fire. Some proprietary billet AR-15 lowers use threaded set screws in place of standard roll pins or rear detent springs; do NOT force Mil-Spec pins into threaded holes.
- Ensure the host AR-15 rifle is completely clear, magazine removed, and chamber visually and physically verified empty before disassembly or parts replacement.
- Perform lower receiver detent and spring installations inside a clear plastic bag or dedicated armorer bench tray with a clevis pin tool to capture springs under tension.
- Apply a light film of synthetic grease or CLP to brass takedown/pivot detents, safety selector detents, and bolt catch plungers prior to insertion to ensure smooth, corrosion-free travel.
- Install the disconnector spring with the wider flared end oriented downward into the disconnector slot, and verify the firing pin retaining pin legs are spread slightly for positive retention inside the bolt carrier.
- Perform a complete mechanical function check—verifying safety selector engagement, trigger reset, bolt catch lock-back, and buffer retainer capture—prior to live-fire testing.
