    Anyone have one? I'm thinking of building one. Will cost me about $700.

    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.

    Are you using a pre or post ban lower?

    I'll be using a post ban. The one our manufacturer makes. I'll be buying two in the next week because we just ordered 60 and they cost me....well...trade secret. Lol

    Now you have to comply with the Romney bans though.

    The Romney bans? You mean no flash suppressor,folding stock or bayonet lug? Who cares? I'll pin the stock,put on a muzzle break and chop the lug off. I don't care. I'll still use my pre-ban mags and I'll pick up a couple blocked pmags just to screw with the range officer on duty, oh wait I'm a range officer, nevermind. Lol

    I think so. Not something I've really looked into though. Kinda pointless when you know people with full autos anyway.

    What's the difference between a pre-ban and post-ban lower? And what ban? a state law or federal ban?

    Oh got it thanks.

    So if there's another ban it will be AWBII so then we'll have pre AWBI and pre AWBII firearms :rolleyes: LOL

    Back to the 300 BO question, I have a PSA 300 upper and it works great with subs and supers. Although, without legal SBR's and suppressors, the 300 looses a lot of its advantages over the 5.56. It shines with efficiency out of short barrels and with subsonic ammo for suppressors.
    The 300 is also lacking efficient bullets that will expand at the slower velocities. I'm sure that will come with time.

    I have a lower ready for a pistol build (SBR's Arne the only NFA items still illegal here under state law) and waiting for a can under a trust. If my trust passes BATFE scrutiny, I'll order my rifle can.

    It cost me about $130 for extra reloading equipment to convert 5.56 cases. I bought the dies, trimmer and harbor freight cutoff tool for that $. I still need annealing gear.

    One benefit that I enjoy is that the supersonic round makes a great hog/deer 30 cal. projectile in an AR platform within 200 yards, where I do all of my hunting. Later, when my suppressor and SBR are approved, I'll use those when I'm stand hunting. By then there should be some subsonic rounds that have some expansion.
