I've got an 0ptics-ready S&W15 . I've been toying with the idea of replacing the front "sight" rail with a real FSB. Apparenlty they're only about $30 on line, and my LGS is telling me $50 to swap the parts.
2 questions:
- how's that price?
- any potential downfalls? Ie, messing up the accuracy/barrel, etc?
Thanks.
