I put the Strikeforce c'piece on mine.
(for myself) it's all about looks and the c'piece really adds to that.
From the start I've been using a Bushnell Trophy red dot , which is abit of overkill for a .22 . This red dot is now on my 12ga turkey gun ( I've also had this sight on a Lee Enfield No5 and a SKS ) . I mounted a el-cheapo reflex type red dot ( e-bay $20 job with a slightly larger dot ) for now , on my Mossy Tact , so far so good at 50yd. I'll put it through the "test" and make a decision after turkey season is over on wether the Bushnell will go back on.
I recently found out that there is a 3x attachment for a reflex sight...huuumm .
