i use an automag p/f with that amzing retro valve, agd intelliframe, 16in boomstick, 68cu stub tank, AA me'lee 88cu, tactical drop forward with on/off, 12v with x-board ------------i also i have 10 of these me and my dad bought to open a field but we decided not too so i use them with nitro for a backup
epansion chamber for co2 other than that nitro or a barrel
simply amazing with its easy strip down. just pull out the cocking pin and pull out the bolt.
-the trigger could use some work but other wise its very fast and will keep up with most guns
not bad for a begginer gun or a backup gun- id use it over one of my tippmanns
