I just mounted a Williams FP TK on my BC and I am really please with it. Last week I replaced the Lyman 17A front sight with a Lyman #20 MJT barrel sight and shot using Anschutz acrylic inserts.
Put ten rounds through the same hole at 100 yards. I will be moving to the 300 yard range shortly....
The FP TK is a great sight and I highly recommend it.
