I love FX rifles, and currently own a sub12 Impact (2nd gen) with .22 ST barrel and .177 STX barrel, and mostly use the .177.
it’s been a very good rifle with 5p accuracy at 30-35 yards and 10p accuracy upto 45 yards, I’ve put 10’000 .177 pellets through it and about 2000 .22 as I mostly use the rifle for bench rest target shooting.

I can’t wait for the crown to become available in the UK as I would like one of them also.
