Not aware of mini shells in 20 gauge, or if the adapter from Opsol will work with the 20 gauge version?PriestTheRunner wrote: ↑Wed Nov 14, 2018 1:32 pmAguila mini shells make it a fantastic gun and much more manageable. With those its fairly comfortable to shoot.
I do know that the adapter & Aguila make a nice combo in 12 gauge!
