Bb Gun Bullet Size

[Bielanskiii]

I have an AEG that shoots 6mm bbs, but I have some .177/4.5mm bbs lying about. Should I avoid using these or would the gun fire them anyway?

Sorry if this is an obvious question, this is a new hobby for me!

Airsoft bb’s are generally 6mm, sometimes 8mm, not .22 inch, so what system are you talking about?

Yeah I meant 6mm, sorry! Edited the post so it makes more sense.

.22 and .177 are airgun pellet sizes

BB gun was a common name in the US for airguns, partly because in the UK we tended to go for shaped pellets and less so for metal Ball Bearing pellets

 

Airsoft guns are designed for 6mm plastic BBs

 

If your gun is .22 then it’s an airgun, but if it is an airsoft gun and you just think it looks like .22 then it could look similar in size

 

At best a .177 pellet will fall out of the barrel, at worst you jam things up and damage the barrel etc

The pack says 1.77cal/4.5mm bbs. I meant 6mm, not .22 (i've been handling an air rifle which shoots .22 so I got confused). I have edited the post.

Firstly most 4.5mm BBs are steel right? i wouldn't put one of those down your AEG barrel at any speed - could scratch it up something nasty.

If you did, most of the air would just escape through the 6mm bore resulting in probably sub 50fps.
Also your hob rubber would not hold the bb in place - it would just role down the barrel.

I wouldn't bother mate.

Alright, thank you.

DON'T PUT THEM IN!

 

As said, they won't fire properly anyway.

 

But worst case they can actually fit inside some feed nozzles right into the piston tube.  That could seriously damage the piston head.

Would you put diesel in a petrol car? 🤣

 

At best they would be crap performance, worst it would do some serious damage to your airsoft gun.
