Why Choose the B&T Telescopic Brace Adapter for MP5K
Purpose-Built MP5K Fit: Interfaces cleanly with MP5K-pattern rear geometry for a factory-grade fit, consistent alignment, and minimal play.
Telescopic, Multi-Position LOP: Collapse for discreet transport and tight spaces; extend for eye-to-optic alignment and increased control through recoil.
Aluminum & Steel Construction: Lightweight aluminum keeps mass down while steel reinforcement adds stiffness and long-term durability under real training cycles.
Matte Black Finish: Low-glare, corrosion-resistant coating looks professional and resists scratches from slings, cases, and barricade work.
Glove-Friendly Adjustments: Smooth rail travel and positive detents make on-the-fly sizing quick and confident—even with gloves.
B&T Precision: Tight tolerances help maintain repeatable cheek index and support consistent point of impact across positions.

Performance Benefits You’ll Notice

Repeatable Mechanics: Defined detents and rigid construction support consistent shoulder index and confidence when switching positions.
Ideal Use Cases
Range & Training: Build efficient posture for standing, kneeling, and barricade shooting on a PDW-size footprint.
Home & Property Defense: Quick, repeatable sizing for different shooters; compact when stored.
Competition / PCC Practice: Micro-adjust length to match optic height and stage demands for faster splits and transitions.
Agency / Duty Trainers: Mirror duty ergonomics on a controllable platform for high-volume reps.

Seat & Align: Interface the adapter fully with the MP5K rear trunnion/receiver before tightening hardware.
Torque & Threadlocker: Use manufacturer-recommended torque and non-permanent threadlocker where appropriate.
Function Check: Cycle through all positions to confirm detent engagement and check clearance with slings, charging handle, and optics.
Range Verify: Confirm optic alignment and test for stability/POI consistency across positions.
Care & Maintenance
Wipe rails and detents after range days; avoid harsh abrasives.
Apply a thin film of quality lubricant to sliding surfaces to maintain smooth travel.
