XTS Sling Plate Adapter Sling Mount Quick Detach Swivel Ambidextrous Design Black SP 04 UPC 767820085838
Product Description
The XTS® Sling Plate Adapter with Quick Detach Swivel (SKU: SP-04 / UPC: 767820085838) replaces standard factory AR-15 receiver end plates to deliver a robust, low-profile ambidextrous sling attachment point at the critical center of gravity on your rifle. Designed for dynamic tactical operators, patrol carbines, and home defense setups, this adapter system facilitates fluid transitions between primary and secondary shoulders while preventing sling webbing from tangling or binding during close-quarters maneuvers.
Crafted entirely from high-grade structural carbon steel, the SP-04 end plate and matching swivel loop are built to withstand severe shock loads, heavy combat kit snagging, and rigorous single-point rifle drops. The surface is treated with an anti-glare, corrosion-resistant black oxide conversion finish that shields the steel substrate against ambient moisture, field abrasives, and harsh chemical bore cleaners. Its low-profile rear footprint ensures zero interference with stock collapsing channels or shooter hand placement along the pistol grip.
The kit arrives complete with a heavy-duty 1.25-inch steel push-button QD swivel that docks securely into the centralized receiver socket. Featuring smooth 360-degree rotational mobility, the assembly allows single-point or convertible two-point slings to articulate naturally with weapon manipulation. When rapid uncoupling is required for vehicle egress or secondary weapon transitions, depressing the recessed center release button disengages the four-ball detent mechanism cleanly and immediately.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits all standard Mil-Spec and Commercial-Spec AR-15, M4, and AR-10 lower receivers using collapsible carbine receiver extensions (buffer tubes). Accepts all standard 1.25-inch webbing. CRITICAL: Not compatible with fixed A1/A2 rifle-length buffer tubes. During installation, take extreme caution not to kink, pinch, or crush the rear takedown pin detent spring located beneath the lower right side of the end plate. Thread the castle nut with the wrench notches facing rearward, torque the castle nut to 38-42 ft-lbs using an armorers wrench, and stake the metal of the end plate into at least one castle nut notch using an automatic center punch to ensure permanent rotational security under live-fire vibration.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Secure the lower receiver in a vise using an approved lower receiver vise block or buffer tube clamp.
- Loosen and unthread the existing castle nut rearward toward the stock using an armorers castle nut wrench, then slide the factory receiver end plate back while capturing the spring-loaded rear takedown pin detent and spring.
- Slide the factory end plate off the buffer tube threads, install the XTS SP-04 adapter with the lower indexing tab facing forward into the receiver pocket, and carefully guide the takedown pin spring into its channel without binding.
- Hand-tighten the castle nut forward against the SP-04 plate, torque the castle nut to 38-42 ft-lbs, stake the end plate into the castle nut staking notch, and verify smooth, positive locking of the push-button QD swivel.
