I bought this to put on a remington versamax. It dropped right in and works flawlessly! My gun has over 20K shells through it and has had many rough seasons hunting ducks over water, snow canadian and specs in fields as well as countless miles hunting upland birds (pheasant, grouse and partridge). I decided to rebuild some of the parts but couldn't find remington parts so a lot of the replacement parts have been benelli. Most of the trigger group components from benelli M2 models will work in the versamax just fine. The shipping was fast, pricing was fair and the quality of the part is perfect!
