I've studied the illustrations in the upper right (SBBK-SBFWD piston cylinder.PNG and SBBK-SBFWD.PNG), and I don't think they demonstrate the subject accurately. The only illustrated design difference between these diagrams is the location and arrangement of the recoil spring. Both sides depict blowback operation. Both "bolts" are shown to move back as shown by the red reference line.
As I understand blow-forward, the frame and breech face remain stationary relative to each other, and the barrel assembly moves forward to provide the cyclic action of the gun.

I fixed the picture. --71.229.74.0 (talk) 22:48, 23 April 2013 (UTC)[reply]
No you didn't. We have two images with a total of 4 blowback operations. --Doesn't matter 15:11 24 April 2013 UTC+2 — Preceding unsigned comment added by 213.160.62.84 (talk) 13:11, 24 April 2013 (UTC)[reply]
It seems that editors who do not understand the subject matter have added guns that do not belong here. The Gyrojet and three other guns have been removed. Blow-forward is a specific style of operation, not a method of unlocking the breech. The energy to unlock a gas-operated firearm comes from a piston. The method of unlocking or reloading may be the mechanical movement of the barrel forward, but the barrel is being propelled forward in those systems by a piston. --Winged Brick (talk) 16:50, 26 February 2017 (UTC)[reply]
I find the illustrations misleading. The primary difference is that in blowback, the 'frame' is fixed to the barrel and the breech-face moves in relation to the frame. The breechface is a part of the moving portion called slide or bolt, depending on the layout of the blowback firearm. In Blow-forward, the frame incorporates a fixed breechface and the barrel moves away from the breech (frame) during the cycle of operation. I am not an artist of any note, but this could certainly be much clearer in the illustration. I will attempt to change the text to reflect this. --Winged Brick (talk) 21:30, 27 February 2017 (UTC)[reply]
