Features of Borka Tools Combination Kit

  • The BCK-MX is an enhanced version of the BTK-E1 specially configured for precision adjustments on scope turret screws. This kit includes both:
  • 4 inch-lbs. Precision Torque Limiter (PTL)
  • 8 inch-lbs. Precision Torque Limiter (PTL)
  • PTL Gear for use with PTL's
  • These low-range PTLs are ideal for delicate applications such as zero-stop and elevation/windage turret screws, helping ensure consistent torque without over-tightening.
  • To accommodate the 4 inch-lbs. PTL, the standard spare T-20 Torx bit from the BTK-ST bit set has been replaced with a 5/64" hex bit specifically selected for compatibility with the included low-torque limiter.
  • This kit is perfect for shooters and optics professionals seeking ultra-precise, repeatable torque settings for scope turret installation, adjustments, and maintenance. Combine that with the modular flexibility of the BTK-E1 and you get a reliable, professional-grade enhanced toolkit for field or bench use.
