This video marks our 40th episode, thanks for watching/reading, lots more to come!
In this episode Matt had the chance to put a few rounds through a replica of a Gerat 06(H). German development of the 06(H) began at Mauser in mid-1944. The 06(H), sometimes referred to as the StG 45(M), was developed from the earlier Gerat 06 which used a gas operated, roller-locked action designed by Wilhelm Stahle.
One of Mauser’s scientists, Dr Carl Maier, analysed the 06’s action and noticed bolt bounce before the action locked. From this he calculated that the heavy gas system could be removed and the bolt simplified by using a roller delayed, rather than locked, blowback action. This is where the rifle gets its “H” suffix, meaning “half-locked”.
The rifle is chambered in 7.92×33 Kurz, feeding from a 30-round StG-44 magazine. It has a stamped sheet metal receiver and an in-line layout, sending the recoil impulse straight back. Despite being lighter than the 06, the 06(H) is equally controllable and handier than its heavier predecessor.
The 06(H) is the genesis of the roller-delayed blowback action line of rifles that progressed through work at CEAM in France, developments in Spain at CETME and finally back in Germany at HK. We’ll have a full video discussing the design, development and history of both the 06 and 06(H) in the future and we’ll also delve deeper into the evolution of the roller-delayed blowback system and the rifles that used it.

Thanks to our friend Chuck over at GunLab for allowing me to shoot his replica 06(H) and helping with filming.
