Description
Borka® Combination Kit – Precision Edition (#BCK-MX)
Ultra-Precise Torque for Optics & Turrets – The Borka® BCK-MX combines the proven versatility of our Extended Configuration (BTK-E1) with dedicated low-range torque limiters for the most delicate precision-scope adjustments. Designed for professional shooters, gunsmiths, and optics technicians who demand repeatable, accurate results every time.
Complete Professional Kit
The BCK-MX includes all the components of the BTK-E1—including extended hex bits and bit extension—plus a specialized precision torque package:
· 4 inch-lbs. Precision Torque Limiter (PTL)
· 8 inch-lbs. Precision Torque Limiter (PTL)
· PTL Gear for seamless use with the included PTLs
These low-range PTLs provide the perfect solution for scope zero-stop and elevation/windage turret screws, delivering consistent, delicate torque without risk of over-tightening.
Important Configuration Note
To accommodate the 4 inch-lbs. PTL, one spare T-20 Torx bit from the BTK-ST bit set has been replaced with a 5/64" hex bit—selected specifically for compatibility with the low-torque limiters.
