MP5K, SP89 Locking Piece - 110 Degree -RCM

US Made Locking Piece. Made from ordnance grade steel, heat treated made to last by RCM. HK no longer makes the 110 degree locking piece as they use the 100 degree locking piece in all 9mm MP5 and MP5K variants. However, in some cases the 110 degree LP still is a must have locking piece. Compatible with:
  • HK MP5K
  • HK SP89
  • MP5 Reverse Stretch, MP5 Compact
  • Custom HK Builds and clones

    I've been chasing proper bolt gap on my new 9KT... out of the box it was at .006, it shot good but way under spec. I installed the new RCM 110 locking piece with a new set of 8mm rollers... bingo. .018 gap. The locking piece fit the PTR bolt head perfectly and everything went together smooth.
