I wonder (and here is the "newb", as the kids say, question) if it would be possible to use an entire cylinder and bolt assembly from a VSR-10 in this gun... but I don't have a diagram of the VSR to compare what it looks like compared to the Blaser model side to side...
In any case, just got the barrel spacer, steel spring guide and 550fps/ M170 spring KA branded parts. But I'll wait to get the KA Piston before I put them in.
Hmm... paid $170 for the rifle (open box special), then $11 on spring guide, $10 on spring, $5 on barrel spacer... then $X? on piston... all of a sudden, not so cheapo...!
