The modern M4 ribbed stock is the same length as an A2 when fully extended.

I thought the M4 stock was 5/8" longer when fully extended?

Is there a difference between the CAR stock LOP and the new M4 stock LOP when fully extended?

Consolidating all of the above entries, just to make sure there is no confusion:

- A2 is 5/8" longer than A1.
- CAR stocks are the same length as an A1 when fully extended.
- M4 stocks are the same length as A2 when fully extended.

The M4 was adopted in 1994. The improved sliding buttstock was developed at Picatinny in 2002.

CAR stocks like this one are A1 length when fully extended:

M4 stocks like this one are A2 length when fully extended:

And are you sure about the 2002 date? Seems like it was a couple years earlier than that.

The ribbed style M4 stock came on new M4s in the Summer of 2002.

Black Rifle II is not a very good reference.

Here's an archived page from Bushmaster's online catalog from back in 2000.

Maybe created before 2000, but only adopted in 2002?

Apparently not issued to regular Army until 2002, but available and referred to as an "M4 stock" before then.
