Benelli 20 & 28 Gauges : Most are Crio+ which we do make in 20 gauge, but do not yet make in 28 Ga. Some are MOBIL which we do make. Please ask us. If threads are flush to muzzle, it is Mobil. If threads are not flush to muzzle it is Crio+. Guns in .410 are Beretta MOBIL and we do have them in stock.

OPT HP (Optima High Performance): NOT to be confused or mistaken or mixed with Optima!! Optima and Optima HP are NOT interchangeable and will blow the barrel if an OPT HP is screwed into an Optima barrel.
