I've got a very important question for /k/:

Alright, so I just got into the whole AR bullshit thing. I was in the Army over a decade ago, and I swear on all things good and holy I remember pic related being called a "bolt carrier assembly".

When the hell did this change? Why did this change? Or did it not change and I'm just an idiot with a defective memory?

The last one.

>>34911329
We still call it that in the Army.. why would you ever think it changed name?
>>
>>34911351
Everywhere I look in the civilian world it's "bolt carrier group"
>>
>>34911369
I think because the word "assembly" in it confuses stupid people, ie almost everyone.
>>
in 10 years it'll only be known as 'bcg' with no one remembering what it stood for
>>

'group' and 'assembly' mean the same thing when describing a, wait for it, *group* of parts that serve a particular function in a machine
