Will the Rifle Basix MAR-1 Silver trigger fit my Marlin Model 917 or 925 rimfire rifle?

No, the MAR-1 model is strictly incompatible with Marlin T-900 and 900-series systems, which includes models 915, 917, 925, 980, 982, and 983 that use E-clip retention pins. This trigger is designed exclusively for pre-2005 Marlin bolt-action rimfire rifles such as the 15, 25, 780, 880 series, and 17V.

How do I adjust the pull weight, and does it affect bolt removal on my rifle?

The trigger features independent, user-adjustable screws for pull weight and sear engagement, offering a factory-rated range of 1.0 lb to 2.5 lbs (approx. 450 g to 1,130 g). However, note that if you adjust the pull weight above 2.0 lbs, it may impede smooth bolt removal on certain Marlin actions.

Does this mechanical trigger require any electrical compliance certification for use in Australia?

No, the Rifle Basix MAR-1 is a purely mechanical fire control group containing zero electronic circuitry and requiring no mains power. Therefore, it does not fall under Australian SAA or RCM electrical regulatory compliance frameworks, though buyers should ensure installation complies with their respective State Firearms Registry guidelines.

Marlin Rimfire Trigger - Rifle Basix MAR-1

The Rifle Basix MAR-1 SILVER is a drop-in aftermarket fire control upgrade engineered for pre-2005 Marlin bolt-action rimfire rifles. CNC-machined from billet T6 6061 aluminium and heat-treated for wear resistance, it directly replaces heavy factory triggers using the rifle's original pivot pin and safety mechanism. The trigger delivers an adjustable pull weight spanning 1.0 lb to 2.5 lbs (approximately 450 g to 1,130 g), with user-adjustable screws for both weight of pull and sear engagement to eliminate creep on compatible .22 Short, .22 Long, .22 LR, .22 WMR, and .17 HMR platforms.
