Seems to be a new version of the venerable 10/22.
Bull bbl, "special" chamber (??) lol
BX-1 trigger assy
Last shot hold open
Extended mag rel
Rear anchor.
Scope mount integral
Kinda funky stock
I think list is $700 ish
Better shoot sub 1/2" at 50 with at least Green Tag, must be sub 1/2" with Center X or it won't sell.
