    Stoeger M3500

    Product worked great! Reduced trigger pull from 7# 10oz to 5# 8oz. The installation video was spot on. It will make a huge difference in the turkey woods for sure. A quality product from a made in the USA company!

    Smoothest Stoeger M3500 trigger pull !

    looking for a smoother and lighter trigger pull ! Look no further M Carbo has you covered with this one. I received my kit super fast and it was simple to install ! Even easier because of the install videos M Carbo makes. Thanks for everything you guys in supporting our troops and 2nd amendment also for making awesome products.

    Just received the product. Very fast shipping. I have purchased and installed other Mcarbo trigger springs and they are perfect. I am sure this one will be as well.

    Stoeger M3500 trigger spring kit reduced trigger pull by 2 1/2 lbs.

    When I purchased my Stoeger M3500 the trigger pull was 7.88 lbs. That was unacceptable, so I called Stoeger. They basically said, "send it back for inspection". In the mean time, I found a video on YouTube by MCARBO. That 15 min. video described how to purchase and replace the trigger / bolt springs for $14.95 to lower trigger drop. I ordered the kit, replaced the springs and now have a trigger pull of 5.30 lbs. I shot a box of shells through it, without incident. I would strongly recommend this product as the first course of action on a Stoeger M3500 trigger reduction problem.
