A reader points this out:

Barrett REC7
Caliber- 6.8 SPC
Weight-7.62 pounds (3.5 kg)
Overall Length-32.4 inch (82.3 cm) stock collapsed
Operation-Semi-automatic, piston operated
Barrel- 16 inch, chrome lined (40.6 cm)
Twist- 1 turn in 10 inches (24.4 cm)

Looks good, but at an MSRP of $2599 it doesn't come cheap.
