This rifled steel made 4.5 inch tunning barrel has been tested to have better shot accuracy and with an increment of up to 3 joules of power compare to the stock barrel. It mimics the original stock barrel exterior so it maintains its legit compliance appearance, while adding power discreetly. Ideal for regions that prohibits marker modification and joules monitoring by the local authority.
