Hv read from the magz. about the blowbacks , maybe this definition will help u understand more:-
- The more popular among which are the Gas Blowbacks (GBB). The GBB allows a realistic, semi-automatic firing of the gun by employing either an on-board, or magazine-stored gas storage system.
- Basically, the same compressed air that propels the BB out of the bore is harnessed to cycle the slide back (hence: blowback).
- This creates the realistic recoil by cycling the slide back and forth while firing the gun. This system gives the gun the capability to empty a magazine as fast as you can pull the trigger, and just as easily reload the gun by inserting a fresh magazine.
- Depending on the type of gas used, the force of the recoil is normally compared to that of a .25 caliber handgun, so the recoil is not tremendous but enough to make shooting realistic
