Alpha Arms 15SA Compatible Chokes

[9mmGunGuy]

Could someone please say whether the following are compatible with the Alpha Arms 15SA?

1. Utas UTS-15 Extended Tactical Choke Tube Product Number: UTAETT1
2. Remington Tactical Choke Tube Ported Ext Cylinder, Black, 12 Gauge Product Number: REM19791

The UTAS choke will work, but the Remington won't. Both the UTAS and 15SA use Beretta MobilChoke pattern threads.
