Mine has a Butler Creek steel barrel .920" fluted.
I JB'd the bore, about 30 strokes. Volquartson trigger & parts.
Won a BR contest with it using Winchester Dynapoint 1080fps stuff. 5 group agg. on one 6-bull target was .222". Range 50 yards.
It is the most accurate .22 I own, the BRNO semi, the nicest, then the Anny.
