H&K MP5 9mm Pistol Build Kit With Flat & Weldment Set
Each MP5 9mm parts kit started life as an iconic German manufactured MP5 that was issued to the border guard and military police for service. During that service, they were carried a ton but rarely fired. In order to import these rare and hard to find MP5 parts kits, the barrels had to be demilled as well as the receiver. Each kit comes with all 6 of the needed US made compliance parts to be legal as a pistol (N/A) rifle, or SBR build.
This is the first time that these iconic early 80’s production kits have been offered in this configuration as a complete pistol build kit here in the U.S. HK Parts build kit is the best-priced value available anywhere. There is a limited supply and they will be gone before you know it.
