My X7 experience...

Beware the 250 Shockwaves, I tried one in my X7 once and literally had to get a hammer out to get it seated. Get some crush-ribs if you want to try that bullet I suggest.

The front sight is not a surprise. I could not get mine on the paper during my first range session. I called T/C, since they didn't even let me finish my explanation before stopping me and asking for my address to mail the new front blade I got the impression this is a known, frequent issue they encounter. They popped one in the mail and I was back out by the following weekend.

With the taller front sight, most loads shoot dead-on at 100 yards with the rear sight mid-range in adjustment:
200grSW and 110gr 777
300gr PR Keith Nose HP 100gr 777

However, this year I sighted it in with 120gr 777 and 300grSW for elk. I needed to take the sight up almost as far as it would go. Indeed, I could have put the lower front sight back on and sighted the rear sight in near the bottom of the ramp.

I recommend picking the primary bullet(s) to be used first, and verifying where they will shoot then ordering the front sight if necessary.

For all the hype about faulty QLAs, every T/C gun I've owned or my direct shooting buddies own has been very accurate and my X7 is no exception. I shoot nice tight 100yd groups, I'm sure they'd be better with a scope but I don't want one on it.

Enjoy!!
