I finally talked my brother in buying a Sport. I went up to his farm, showed him how to clean it and take it apart and gave him a bore snake and a bottle of CLP. We still haven't had the chance to go shooting.
A flyer came last week from a LGS that had the Sport for $528. When he background check was complete, so he bought a second Sport and when he picked it up, they also had a pallet of the Blackout Sport. I didn't even know they were selling a Blackout Sport.
