It would be a nice touch if they squared off the cross-grooves and allowed some standard, "1-bar" picatinny accessories to mount. That would open compatibility to a huge range of accessories like 3rd party lights, lasers, sights and grips without the need for additional accessory picatinny rail adapters.
The 13.9" free float rail has an anticipated mid-year release ($TBD), and the 7" drop-in version (MSRP $345) should be out in late April. www.surefire.com
