These guys definitely know how to provide good service. They followed up my order with several e-mails to make sure all went well. Their spring made the horrible trigger on this rifle feel like one should feel. Great improvement. I would recommend that if your looking to improve the trigger one of these Marlins check these guys out. No one else seems to be interested in doing this with these rifles. Thanks M*Carbo.

I just had the M*CARDO trigger spring installed on my Marlin Model 25 it was a welcome improvement to the heavier stock spring for target shooting. It was quick to install and a great bargain.
