This bundle turns your MK23 into the sidearm everyone quietly wishes they had brought: a Morpheus barrel, an SR Hop bucking, a TDC kit that finally lets you adjust the hop properly, and a pair of Wii Tech springs that sort out feeding and trigger reset. One order, one afternoon, and a pistol that hits what you aim at.

What's included

• "Morpheus" Dual Bore MK23 Barrel 133MM – 6.05 mm SUS304 seamless stainless steel with a dual bore tapered end crown, made to fit MK23 models. Harder to machine than the cheaper SUS303 steel most brands use, and far more durable and corrosion resistant for it.
• SR Hop Bucking 60° (Purple) – a hybrid between an R-hop and a bucking with an enlarged, extended patch for the longest possible lift path and a flat, predictable BB flight.
• MK23/SSX23 TDC Kit (Hop Plate + TDC Hood) – replaces all the stock hopup parts with an adjustable TDC function on your stock chamber. The TDC screw has a flat bottom that lands perfectly on the island of the Stalker Prowler hop plate, with improved fitment and alignment.
• Wii Tech MK23/SSX23 200% Loading Nozzle Forward Spring – piano steel wire, made to tight tolerances, for a better air seal between loading nozzle and hopup.
• Wii Tech MK23/SSX23 180% Loading Nozzle Returning Spring – speeds up nozzle return and smooths out BB loading, the classic fix for a sticky trigger reset.

Why buy it as a bundle

The barrel and bucking set the flight path, the TDC kit lets you tune that hop from the top with real precision instead of shimming and hoping, and the two Wii Tech springs keep the gun feeding and resetting crisply so every well-aimed shot actually goes out. The 133 mm barrel keeps the whole thing compact, so your MK23 stays the quiet, quick-handling pistol it is meant to be.

Good to know

• Fits Tokyo Marui, STTI, ASG and Novritsch SSX23 MK23 models using the stock hopup chamber.
• Installation means stripping your hopup, barrel assembly and loading nozzle. Very doable at the kitchen table, and your local tech can handle it if you'd rather not.
• Always check your joule output after installation before you take it to the field.
