Description

H&K MP5K/SP89/SP5K/SP5K PDW 9mm #28 Locking Piece

This is the locking piece that is recommended when using a suppressor and 147-grain or heavier bullets. This will slow the rate of fire while suppressed to safe levels. This locking piece is 80 degrees rather than the 100 or 110 locking piece found in most MP5K or SP89's. This is the best option for those that need the best parts in their build to keep them authentic and run for years to come. 

Only a few on hand! Get them while you can. 

Compatible with:

  • HK MP5K
  • HK SP89
  • HK SP5K
  • HK SP5K PDW
  • In spec. clones and builds

    This is HK's 80 degree locking piece. It is a unicorn, and until recently has been impossible to find anywhere. Do you need it? Based on my research, ONLY IF ALL THREE of the following apply: 1) You have an MP5K/HK SP5K. 2) You are shooting with a suppressor attached. 3) You are shooting subsonic ammo (e.g., 147 grain or heavier). I do not know about clones. Good luck with that. One final word: Do not use the non-HK (i.e. cheaper) version(s) of this 80 degree locking piece. Based on my experience, the non-HK locking piece(s) is/are out-of-spec, do not fit, and otherwise make excellent paper-weights. Cheers...
