So nice once you get that SBR designation so you can swap uppers. This is one of my favorite combinations. It's a Spikes Tactical Wart Hog lower and a KnightArmco/AAC upper in .300 BO. I always shoot this with an AAC SDN 7.62 suppressor. The red dot is a Riton Optics 1 Tactix RRD. Sadly I got hooked on the Blackout round at least 15 years ago and try to keep three dialed-in with different grain bullets. I use PNW Arms (no longer in business) 125 Nosler BT at 2100 fps in the below rifle. These bullets are the most accurate BO ammo that I have. My second favorite is Gemtec 187 gr polymer tipped. Quiet and accurate.
