I don't have a covered bench at the house so I have to move my bench between rains so the wood stays good and it is muddy off the concrete where I keep it, so I rigged up a tripod mount using a section of aluminum I had and extra ATV mounts.
Holds it fairly steady. Sighted in a $35 estate sale Remington 510 in I refinished for my little girl today with it, good enough for a 2" 5 shot group at 60 yards with "irons".
Figured it was useful enough to post here.
In use, Sun was behind the trap by the time I made a video but you can still see the plate of you look close enough.
