Please note these all have different blemish marks on them. They are only cosmetic, the product is still fully functional. 


Our new MP5K to MP5 stock adapter is the perfect addition for those looking for a stock that provides a better line of sight and a better cheek rest position like the MP5 A2 fixed stock does. This stock adapter will allow you to install any MP5 fixed stock onto a MP5K reciever. Made out of aircraft grade aluminum and cerakote finsh that will increase durability by providing an abrasion, and chemical resistance for a long lasting finish. This is also the best options for those that like the MP5 Reverse stretch look with out having to do a complete build. Made 100% in the USA. 


Compatible with:

  • MP5K, SP5K, SP89
  • AP5-P, AP5-M 
  • ZF-5K
  • MP5K clones that are in spec

    Great condition! Had slight fittment issue.

    Posted by James K. on 6th Dec 2023

    First off, this was advertised as a "blemish" SKU. if there really is a blemish on there, i cant find it! It came in excellent condition. Dont hesitate to buy if thats your concern! Your mileage may vary, but, I attached this to my AP5-M, with the pistol to adapter fit, it was perfect, rock solid lockup. However, when i attached the adapter to an SBT5A to the adapter, there was a significant amount of up and down play in the lockup. To fix this, i stuff some cleaning swatches in the adapter channel and now the lockup is very tight. Also, I had to remove the H buffer from the SBT5A in order for it to fully line up and attach. Feels great now! Cant wait to take it to the range and try it out!
