I am the author of the development and technology for the refinement of pneumatic guns. Thanks to this, I completely eliminate all the shortcomings! Shotguns acquire power, accuracy, increased penetrating power and firing distance, easy loading, complete absence of toss, quiet shot and shotguns become universal, ideal! The resource, functionality and reliability are increasing! 100% guarantee, this is the end of the evolution of gun making! I invite big business, the Federation of Underwater Shooting and Spearfishing, sports teams, and individuals to cooperate. The technology is on sale! The shotguns, modified by me, do not require maintenance and change of lubricant, within 8-10 years!Subject to correct operation and desalination of the gun, after sea and ocean hunting! The piston, practically forever! I speak Russian only.
