According to the web site, it can be purchased as a complete rifle in camo or as a tactical upper with 13" free float tube. It has 1 in 7.5 twist and a 5R barrel.
I've ordered an upper.
The Remington Sub sonic loads in 300 BLK look interesting to me. Not a bad price. The Hornady ammo I was able to get for testing a pre-production unit was 300 Whisper and all the 110 gr load. No subsonic available from them at the time.
