Description, Features & Specifications

Description

Unlock Safe / Semi / Full-Auto on your mechanical First Strike T15 with the Legacy Performance Selective-Fire Upgrade. Designed by the original T15 engineer, this drop-in kit replaces the factory trigger module and adds a left/right selector for instant mode changes. The included lighter main spring reduces kick and air use, while the updated Legacy bolt geometry feeds today’s First Strike® rounds more reliably.

What’s included

  • Select-Fire trigger module (Safe/Semi/Full-Auto)

  • Ambidextrous selector/safety

  • Legacy performance bolt (re-profiled face for FSR & roundball)

  • Lighter mainspring + bumper

  • Small parts for a complete install

Why it’s better

  • Easy installation: true drop-in module; no repeated teardown to “chase” timing

  • Adjustable ROF: tune with a 5/64" hex through the top of the module (approx. 10–15+ bps window)

  • Smoother cycling: lighter spring lowers recoil and air consumption, reducing long-term wear

  • Reliable feeding: revised bolt face improves interaction with modern FSR

Compatibility

  • Fits all First Strike T15 markers (mechanical).

  • Works with standard 800–850 psi tanks; no 950–1000 psi “workarounds” needed.

Notes & best practices

  • Always chronograph and respect your field’s ROF/ramping limits.

  • Lightly oil metal-to-metal contact points during routine maintenance.

  • If you only want the lighter spring or the revised bolt, those components can be installed independently.

XTREME Returns

As a small business, we face a choice: we can either raise all of our prices to cover the cost of returns, or we can keep our prices low and offer an optional Return Guarantee. We chose the second option because it's fairer to you. That $5 goes directly toward the logistics of a pre-paid return, meaning you get a "no-questions-asked" experience without us having to inflate the cost of every item in our shop. It keeps us independent and keeps your wallet happy. When you shop with us, your order isn’t just a number—it’s handled by a small team that cares about the gear we sell. Because we don't have the massive overhead of a giant company, we use this $5 guarantee to bridge the gap. It provides you with a pre-paid, priority return path, ensuring that if you need to send something back, we can process it immediately and get your refund or exchange moving. Thank you so much for understanding.
