My latest project is a semi-auto NFA registered short barreled rifle, namely a WWII German MP28. Parts on hand, and have started building but must wait for the Form 1 to be approved before completing. Currently waiting on 3 form 1's for other projects. The MP 28 was a post WWII improvement on the MP 18. It quickly became popular with the Waffen SS and Gestapo. Although it was used more frequently with German police forces, the MP 28 served with standard fighting units, eastern European Axis counties, and even the Polish Underground. After WWII, the submachine gun saw occasional usage by guerrilla forces during Cold War conflicts, such as the Viet Cong and Khmer Rouge.
