Just wanted to verify, the Predatar 5.56 is NOT a mid length correct?
And the V5 DD is?

Debating on which to get.

Did you visit each manufacturer's websites? I ask because the information you seek is specifically given by them on their sites.

Google it.

Well i know the DD is, I can't tell by looking at the Larue website... i dont see anywhere saying Carbine length or midlength... you can't just tell me? -__-" lol
