HaleyStrategicThorntailSBRLightMount–PicatinnyAdapter(forM300/M600stylemounts)

Description

Download this STL Model for 3D printer made by aruquense. This adapter converts your Haley Strategic Thorntail SBR Light Mount (or replica) from a Surefire M300/M600 interface to a standard Picatinny rail. It allows you to attach compact lights or lasers such as Olight PL3R, PL-Mini, or similar Picatinny-compatible accessories. By positioning the light further forward, the adapter helps reduce barrel shadow when the light is on — giving you a clearer, more realistic beam projection. 🧩 Printing Recommendations Material: PETG (recommended for strength and heat resistance) Layer height: 0.12–0.16 mm (you can go lower for better detail since it’s a small piece, but never at the cost of strength) Perimeters / Walls: at least 4 perimeters Infill: 40–60 % (Grid or Gyroid pattern) Supports: Required only underneath the part Orientation: print lying flat on the largest surface for best strength and finish 🔩 Assembly Insert the adapter into the Thorntail SBR mount where the Surefire M300/M600 light would normally attach. Pass an M4 screw through the designed hole and secure it with an M4 nut on the opposite side. The metal-to-PETG pressure provides a firm and reliable hold for your light or laser. ⚠️ Notes Designed for airsoft replicas and training setups — not suitable for real firearms. Make sure to tighten all screws securely before use. Dimensions are optimized for standard Thorntail-style mounts but may require minor adjustments depending on your printer calibration.
