Looking for a good shoulder rest for sighting talon

Hello all,

I’m looking for a decently priced shoulder rest for the purpose of sighting in the laser on my talon. The talon has an unusual straight shape to it (compared to a regular rifle), so I figured some rests would work better than others, and some not at all. I don’t think that bean/sand bags are going to work for me because I have to reach up and tweak with the laser screws after a shot, and that makes holding the thing steady impossible (at least for me). Many thanks for any feedback!
