I have found in the past if you put to much pressure in the ram of the HW90 the cocking shoe tends to break on cocking & then the cocking lever rams into the trigger mech' & shafts it up & they are bl##dy expensive to repair' but they are good for around 17-18ftb in fac form' but the fac laza HW80 is the better gun more reliable' better trigger mech & just as accurate'
