SP89 ,MP5K ,MP5 ,HK53 Clone, Navy trigger housing pack

For everything I can tell, it's brand new. I don't see any date codes or other markings for that matter beyond the pictograms. The ears are very wide, and need to be thinned to fit the common trigger pack shelf. Uses the SEF selector (as opposed to the navi fbi ambi). I'm pleased. Can't beat the price.
