PSA brand 7.5" .300 Blackout pistol upper. 1:8 twist. 7" lightweight M-lok rail. Comes with factory BCG and CH. Bird cage flash hider is not clocked, as I ran this suppressed with a QD device.
Accurate, fun little pistol upper. Less than 300 rounds through this, most subsonic, although I didn't keep a round count for this upper.
Package comes with -
Dies - Hornady Custom Grade 300 Blackout dies with shellholder
Brass -
* New starline (ran through a sizer already) - 211
* Mixed headstamp, primed - 80
* Mixed headstamp, not processed - 170
Bullets -
* 110gr Hornady Vmax - 393
Factory ammo -
* 200gr S&B subsonic FMJ.
Reloaded ammo - to be treated as components. I assume no responsibility for the viability of these loads.
* 190gr SubX - 47 rounds. 9.2gr IMR 4227, 190gr SubX, CCI #41 primer, new Starline brass. Velocity was 960fps and was utterly quiet but still cycled just fine. Shoots between on average .75-1" depending on how shaky you are.
* 110Gr Barnes TacTX - 45 rounds. 19.3gr H110, 110gr TacTX, CCI #41 primer, new starline brass. Velocity was 2100fps. Cycled great suppressed and not. Shot repeatable 5 shot groups around .9". The same load data worked for 110gr Hornady VMax.
* 110gr Vmax - 87 rounds. Exact same load data as the 110gr TacTx.
$640 shipped. I'll not assume responsibility for your state laws, so please be sure you're in a state that allows this. If you want to buy a lower as well and make a full package, we can talk
