Many factory triggers are adjustable or can be tuned to meet your requirements. This job is best left to those of us with the testing equipment to ensure it is done safely. It may also void your rifle warranty if it is done at home.
However, many customers require a trigger setting outside the safe working parameters of the factory fitted trigger. To meet this need we stock replacement trigger units for most rifles from makers including Timney, Jewell, Rifle Basix etc.
