On an M1-A, if you're looking for increased accuracy and accessory rails, I prefer the JAE. It's more an integrated stock, more "of a piece" than the CA legal EBR. The coolest version of the EBR is the one we can't have here. But it you look at a JAE on a loaded or Socom, you get ALL the rails, the scope mount built INTO the receiver of the gun (with extended cluster rail, etc)
Damn I love it. Putting one on a SOCOM II tomorrow. I mean, took at this, and it actually makes the gun shoot better, too.
