Depends on where you go;
I got (1) from FORTIS MFG themselves it was $209 from them directly (also took the longest to get from them but it was a pre-order)
The (2nd) one I got was from ROG TAC out of a stroke of luck in stock, they were always sold out as was Rainier Arms, both of these guys are a little cheaper at $199.
FORTIS MFG has a 14" REV Rail coming out plus a Aimpoint micro mount to match the look of the rail in 1/3 co-witness.
