Red Army Airsoft takes a good look at the OTs-14 "Groza," the first serial airsoft replica of the bullpup rifle from the Russian company Strike Arms. The rifle is said to have high authenticity, being built almost entirely from steel and finished with a genuine "Grozin" weapon coating. A key feature is the custom, milled gearbox developed by Strike Arms from scratch to precisely fit the dimensions of the real rifle's receiver.

Whilst designated as Thunder HTs-14 by Hephaestus Custom, everybody will call this the OC-14 "Groza" ("Thunderstorm") as it is indeed patterned after the bullpup AK even the number and name designation will give you an idea. The video shows it being test fired and since this is in cooperation with GHK airsoft, this got the pedigree of the hard-kick gas blowbacks from GHK.
