SIG MPX moderated
SIG MPX from BAR (airgunbuyer.com), silencer adapter (in place of SIG muzzle break) from BestFittings.co.uk & Weirauch silencer from CORE94.com.
Red dot sight & telescopic 6"-9" bipod (with Picatinny rail adapter) from Amazon.co.uk.
FYI the moderator helps reduce the noise, but an awful lot comes from the magazine well, so a further improvement might be lining the mag well with insulation, or even a seal; though that might slow-down rapid reloads.
