8" 300 BLK Suppressed with Subsonics

I got back a handful of form 1 stamps and just wanted to take some short videos. Ammo was specifically Hornady's Sub-X 300 BLK. Quietest of the handful of types I brought.

Parts:
- 8" Ballistic Advantage 300 BLK Barrel
- Clamp-on Superlative Arms AGB
- Flashlight: Weltool Body, Weltool Rear Switch, Surefire M600DF Head
- Rearden 1 Cell Brake
- Omega 36M (full configuration)
- RRA National Match trigger
- Magpul SL-M
- Generic Microbest BCG
- HRF Magwell (have had it forever, might as well just use it)

I had a Surefeed 30/20 rd mag and a 20rd duramag. The duramag 20rd worked the best feeding wise. I'm waiting on 300 BLK specific PMAGs as I don't want to deal with figuring out which mags feed best for 300.
