Title: qb57 problem
Post by: tennx on March 04, 2016, 10:59:19 PM

My qb57 has started not grouping,first on my 177 barrel...I thought it might have sprung the UTG scope, so I put on my 22 barrel with red dot, same things will not group...both barrels were on the money...any body got any answers....thanks

Possibly a  damaged spring or piston seal. I just finished shooting mine with the 22 barrel installed, then mounted a BSA essential scope.

Since it's both barrels, it's something on the power plant end. Breech seal, piston seal, or spring.
