Well fair enough that you've spotted it correctly, but if you scroll up you can see I wasn't the only one who interpreted it that way so I'm not sure it was 100% clear. This is why the quote button exists - otherwise it's assumed you're replying to the post just before/couple of posts just before your own. I believe the replies were coming in fast though and that tends to make it a mess when multiple people are typing at the same time.
Reading it back now with the context provided it seems obvious to me too, but given the nature of the OP I hope you can sympathise with me (and at least one other) thinking it's probably not the best idea to be giving your little brother an airsoft gun to run about with - irrespective of whether dry-firing is going to cause an issue. Believe me - this isn't the fist time we've seen this kind of idiocy and every time the excuse is something along the lines of 'it's not a real gun'. Sorry for the misunderstanding.
