Introducing the pinnacle of performance builds—a terrifying 45 RPS dual-selector monster. No corners have been cut; this is exactly what you'd expect from a fully built, top-tier airsoft gun. I designed this build to be fast, efficient, and relentlessly reliable.
Every time you pull the trigger, you'll feel the difference—and when you flip to full auto, heads will turn. You’ll finally be that guy everyone’s yelling at:
“No full auto in the buildings!”
Step 1: Disassembly and Cleaning
This build started with a complete teardown—and nearly every original part was tossed.
The factory gearbox was replaced with the ultra-durable Retro Arms Immortal gearbox shell, known for its precision and longevity.
Motor Replacement
The heart of the build is the legendary Real Deal Golden Boy motor—ultra-reliable, snappy, and powerful under stress.
Gears
Replaced with the incredible 18:1 Real Deal Airsoft DSG gear set. This set has the best tappet plate timing among DSG setups and is known for its near-indestructible performance.
Bushings
Installed Real Deal FLT bushings—designed for minimal resistance and unmatched longevity. A true zero-failure part.
Piston Work
The original piston has been replaced with the Real Deal Ultimate DSG piston, specifically built to handle the extreme stress of high-speed builds.
Piston Head Upgrade
Upgraded to the FPS Softair piston head, my go-to choice for DSG builds. It's the lightest piston head I've tested and delivers outstanding air seal and performance under pressure.
Nozzle Upgrade
Installed a 21.1mm POM nozzle for a perfect air seal.
(Note: If you opt for the upgraded hop-up, this will be swapped for a 21.0mm nozzle for optimal fit.)
Perun Pro
The Perun Pro is one of the best MOSFETs on the market, offering every feature you could possibly want. I can also modify the original trigger to have the trigger feel, just like it would normally be on safe.
Cylinder Head
Finished off with the Real Deal Cylinder Head, built to endure the harsh abuse of a DSG setup. It features a thicker nozzle shaft for improved air seal and added stability.
