Which specific Ruger centrefire rifle models are compatible with the RU-MKII SILVER trigger?

This replacement trigger is designed for Ruger bolt-action centrefire rifles including the M77, M77 Mark II, Hawkeye models featuring factory LC6 triggers, and the Ruger Gunsite Scout. It is important to note that it is completely incompatible with Ruger American rifles, M77 Alaskan models, M77 Target/Varmint variants, and Ruger rimfire or pistol-calibre models which require different triggers like the RU-R.

What is the adjustable pull weight range and how does it perform in field hunting versus bench shooting?

The Rifle Basix RU-MKII SILVER features an adjustable pull weight ranging from 14 oz to 2.5 lbs, replacing heavy factory triggers that often sit between 4.5 and 6 lbs. For precise bench and target shooting, the lower 14 oz setting delivers a crisp, creep-free break, whereas setting it closer to the 2.0 to 2.5 lb limit is recommended for safer carry during multi-day bush and outback hunting trips.

Does the installation process retain the factory safety mechanism on Ruger M77 and Hawkeye actions?

Yes, the trigger incorporates a unique eccentric-tip safety adjustment screw specifically engineered to ensure proper engagement and timing with the factory Ruger safety mechanism. The drop-in DIY design includes an installation hardware pack, hex wrenches, and instructions to assist with safe fitment, though compliance with state and territory firearms modification laws must always be maintained during installation in Australia.

Who is the Rifle Basix Silver Replacement Trigger For Ruger Centrefire Rifles 14oz-2.5lbs for?

Long-range varmint hunters — Requires an adjustable pull weight down to 14 oz to eliminate trigger creep and avoid pulling off target during precise long-range shot placement.
Centrefire bench and target shooters — Relies on a crisp, lightweight trigger release adjustable within the 14 oz to 2.5 lbs operating envelope, replacing factory triggers that pull between 4.5 and 6 lbs.

Less suitable for: Shooters using Ruger American rifles, Ruger M77 Alaskan models, Ruger rimfire or rotary-magazine pistol calibres (.357 Mag, .44 Mag), or target rifles requiring an ultra-light pull weight below the 14 oz threshold (down to 8–12 oz); these platforms require platform-specific rimfire triggers, dedicated Ruger American replacement units, or specialised two-stage target triggers.
