Very much still a competitive set (except for the 22short, though that can be converted to LR). The "expert" version barrel shroud costs about $150 and turning the barrel to round, easy modification but not really necessary as the recoil reduction system has only a small effect. Other big change was the two stage trigger, though a lot of folks prefer the older single stage. Other difference is the expert frame is carbon fibre rather than aluminium. It is a modular system and very flexible. No worries about 32 bullets they are the most common round in centre fire precision bullseye shooting. Harvey at AirgunsPlus usually has plenty.
