Don't let my wife know (actually she knows, she just likes to gripe about me buying stuff), but I have 2 that are built, a 9 1/2" SBR/Pistol upper waiting for a tax stamp, a suppressor in FFL prison waiting for the tax stamp, and I just received a 10 1/2" barrel today for another one down the road.
I love em. All my other stuff has taken a backseat to the Blackouts, I rarely shoot anything else anymore. If you can build one for $700 you are doing good. I have a PSA, a CMMG, and a Core15,
The neat thing about them is a barrel change is all that's necessary and now you're flinging .30 cal rounds downrange. Ammo prices are dropping and more places are carrying it. It's a reloaders dream because you can use .223 brass. The only downside is that it isn't a distance shooter. Best at 200 yards in, okay to 300 yards with a lot of bullet drop.
