HELP! I'm getting ready to drop the hammer on my first AR and I could use some insight. I finally decided on the RRA Elite CAR A4. I'd like to add a vertical grip and maybe some other goodies later on so I'm ordering a FF rail system with the rifle. Here's the question:

On the seller's website they list the DD 9.5FSB as an option for the Elite CAR A4. Isn't the 9.5FSB for carbine length gas systems? The CAR A4 is a full length gas system/midlength rifle, right? I'm thinking the DD 9.0 is the way to go. Which one should I get? Would both of them fit the rifle?

Thanks in advance-
Coda

DD 7.0 Carbine
DD 9.0 Mid-length <-- for Elite CAR A4
DD 12.0 Rifle

ETA 9.5 is for Carbine not Mid-length
