Each large stock push pin is used to retain the stock to the receiver on the 90 series of firearms. Large push pins are for the stock and the small push pin is for the forearm and lower. The HK German genuine push pins are take off’s from demilled G3 rifles. They are in 100% working order but will have finish wear from being used on German military rifles. Stock up as we offer the best pricing in the country on this hard to find item. A great replacement, spare part to keep on hand as they fit all of the 90 series firearms below:

  • HK91, G3, PTR
  • HK 93, 33, 53
  • MP5, 94, SP5
  • Clones or other custom builds
  • GSG-5 & MP5 .22

The large push pin is an all steel pin 7mm long and 41mm in length overall

Please note: that the GSG5 will take the small handguard or lower push pins without issue but the large push pins require an easy modification by enlarging the opening through the buttstock to use the large push pin 9/32 or 7mm in diameter (takes only a few mins). The MP5K, SP5K and other MP5K style clones use the SMALL push pins not the large.
