I have a BSA Ultra in .177 It's not the MMC and not the SE. Unusual I know. Anyway, it has the standard 170mm tube and I will probably buy a 250mm tube for more shots and this means I can still use the moderator.

My question is, is the Ultra regulated at all? Surely it has a standard BSA regulator? I've seen a standard BSA Scorpion regulator (From a .177 rifle). The seller says it will fit the Ultras.

Will the Scorpion regulator help?

Cheers
