I topped my son's with a Bushnell Trophy multi-reticle red-dot. We've tried the factory full, the HeviShot and the Longbeard XR choke tubes. We're currently getting 145 hits on 8x11 paper at 40 yards with Longbeard XR #6 thru the Longbeard tube . I might need to try the TSS. FYI, just so you know, it will also punch 1 inch holes at 50 and 100 yards with Lightfield slugs and a Carlson's rifled choke tube.
