Most likely, the gas port is dirty and not enough gas is getting through to cycle the action. It could be that the chamber is dirty of corroded and not releasing the hull or the extractor could be damaged and not pulling the hull out. Clean the gun well and inspect the extractor.
Weak spring, bad magazine, dirt, etc..
Shell-ejecting airsoft guns tend to eject their shells using a spring loaded system. once the bolt, or slide is drawn back after firing, the spring will force the spent shell out of the gun
To cock an AK47 means to pull the handle back which sets the firing pin, so that when you pull the trigger the firing pin goes forward and detonates the primer thus firing a shot. The AK47 being a semiautomatic weapon ejects the fired (spent) shell, as the slide goes back to eject the shell sets the firing pin for the next round.
Your rifle was manufactured by Winchester as their model 121. The spent shell is removed from the chamber by action of the right and left extractors and is then bounced out by bumping agains the ejector. Look for problems there. Parts are available from gunpartscorp.com.
Yes
About 157 mins spent in action... not including time outs and inning switches
To collect your spent shell casings.
I'm not certain what you mean, "how do you use a boltaction", but I'll go with it anyway. Bolt action, simply refers to the mechanism that ejects the old shell and loads a new shell into the chamber. The bolt action is a kind of handle on top of the gun, and when you want to load a shell, and this is assuming it has the capacity for more than one shell, you raise the handle up, and pull it back;this will eject a spent shell if you've already fired it; then push the bolt forward, which loads a new shell. If it's a single shell capacity, or single shot, you'll have to follow the above instructions, but load the shell in manually after you've opened the chamber by pulling back the bolt. Clear as mud.
I have the same question. Did you find an answer?
"They could match extractor marks on the shell, yes." If they don't have the gun and it's registered: Highly unlikely, unless it being registered they also get a spent shell casing with the extractor marks and firing pin indent on the firing cap. Also, if you don't "police" your brass, they have the shell casings at the scene, where there is likely a casing with your finger prints (loading the firearm) and possibly DNA (sweat or blood on the casing). Realistically though, if it's a standard shotgun, smooth bore barrel, and you shoot rifled slugs or buckshot and leave no evidence of the shell casings behind, they would have a hard time matching it to just the projectile part of it.
A bolt is one of the main components of a firearm - it's a part in loading the cartridge, firing (in conjunction with a firing pin), and ejecting the spent cartridge.
Is the shell still seated in the chamber and not attached to the bolt as it comes back?The extractor may be broken or bent or worn.Look at the spent shell, are there marks that look like the extractor grabbed the shell but couldn't pull it out?It could be a magazine issue. Is the spent shell hitting the shells in the magazine as the bolt comes back?Check the next shell in the mag for marks.Is the shell attached to the bolt but not kicking out the port?The ejector is bent or broken or worn.Is the bolt not coming back far enough to eject the shell?Check the gas valve and system.Does it only happen with one kind of ammo?
