I have two Buckmarks and both have been upgraded with many Tac-Sol parts. My first gun was new but when I decided to get another knowing it was going to go through a conversion I found a used one pretty cheap. One of the Buckmarks has the Tac-Sol 7.25" bbl, TS integral scope rail, TS fibre-optic front sight and TS colored grips. The other has the TS 5.5" bbl with comp, TS integral scope rail, TS colored grips and fastfire dot (although I might switch to a C-more). They are both set up with the specific parts I wanted and I have been very happy with the results.
