Only when you are out of bbs in your magazine
A blowback airsoft gun, is a co2 or gas powered airsoft gun where the slide on the top of the gun moves back when fired. Some people like these guns because they look cool when fired, however they use more co2 or gas.
Blowback pistols are obviously more expensive than non-blowback pistols. On the other hand non-blowback pistols generally have a higher fps and are alot cheaper. It seems that they can use CO2 with less damage or wear and tear to the gun. They seem harder to clean and it seems as though alot of them have internal magazines which are a bit annoying to load. Blowback pistols are obviously easier to load and easier to clean, however it seems as though alot of guns have atleast one problem. That problem could be with a leaking or a slide that doesn't go back all the way. Blowback pistols ALWAYS seem like they have a leaky mag problem and are gas whores, while non-blowback pistols are extremely gas efficient and there mags never leak.
No. There are a few that do not lock back. These are not really Blowbacks. On these, When you pull the trigger you actually move the slide back (Your finger is doing all the work) and it flies forward to fire the BB. The best way to check for real Blowback, is take a Blowback that is empty, and pull the slide back. If it locks back in place, then it will lock when you empty all the BB's after shooting. Then take the BB clip out and pull again on the slide and it should slide all the way forward. Then put the BB clip back in.
When the slide of the gun goes back, it is often mistaken for blowback
Blowback is when the top of the pistol (the Slide) "Blows Back" and reloads the next shot when the trigger is pulled just like a real semi-auto firearm.
One in which the slide does not move when fired.
You probably have your slide cocked back. If it isnt, then you probably have some kind of internal mechanism problem that needs fixing. Email me at vino12@aim.com if you have anymore questions about airsoft or real guns and their ammunitions.
bang it on the ground
blowback is when the bolt of the rifle, ( the thing that pushes the ball out of the barrel and at your opponent or target) blows back, or the slide on the pistol goes back, after every shot. usually its gas or electric guns, never spring action guns. non-blowback does not have this feature, without it it is much less realistic, and less cool. but when using rifles or SMGs, it doesn't exactly matter. but it does make it look cool.
An airsoft hicap chamber is in a magazine (clip) that has an opening that you slide/flip open to fill with bb's... it has a higher cap (hense the name 250-300 bbs are a possible amount) It is better if you shoot alot but it has to be wound with a little wheel on the bottom to be used.
Blowback on a BB gun is a repeater. When you pull the trigger the gun fires and the top of the gun reciprocates (Blowsback) and auto load and cocks the next shot. If you have ever seen a modern forearm slide back an forth each time it is fired then you have seen Blowback.
Most .22 LR semiautomatic handguns operate by blowback. Basically, the weight of the slide and the recoil spring hold the casing in the chamber long enough for the bullet to leave the barrel. There is no need to for barrel and slide to lock for a low-powered round like the 22LR.
