For this price you'd expect this tiny piece of metal to be finished flawlessly, but it is not. The contact surface is not well finished at all. After some wear there are clear machining marks showing.
Action became gritty and the lockstick is pretty bad too. It gets a bit better after some use, but it still remains grittier than the original action. Considering you can get a set of three basic steel lock bars from aliexpress for 10 bucks (they are probably also better finished than this), Flytanium is clearly ripping you off here. Their scales are great but this is not acceptable.
