hw100 almost blew me away

[huddies 1]

in my hunt for the best air rifle for my budget i thought i had almost set myself on a bsa r-10 , today i find a mk2 hw100 for just over 600 , a little over budget but what a gun, i then found a mk1 . Not quite so good as no quick fill and no real moderator. For 450. Now the question is , i have read of barrel changes to incorporate a moderator, but with no costing, and do you lose much from not having the quick fill. What a gun though, glad i got to try them out. i am leaning toward the hw100 slightly. I like the side cocking, had a go of the aas410 and put that to bed, the cocking action was much stiffer than the r-10. oh decision time, if anyone could shed some light on the barrel change,

The HW100 should have a mod as standard, or so I thought?
