It's intimidation factor to new players. It's high accuracy even stock. It's easy on co2. High rate of fire without chopping (rarely). Durability. It's balance after firing usually keeps you in the same pattern. Super gun stock and eats Tippmann's(HaHaHa Risch!).
The allen bolts will probably need to be removed and replaced there in to tight from the factory. It's not field strippable easily. Cocking bolt sucks!
A great gun at a great price it's been my favorite and I haven't had any problems with it . PMI Bigball works great. and SuperSwirl is decent but my favorite I only used once before it got to cold was Carnivore 2000 rounds and not one broken ball. Can be customized but I haven't had a reason to yet I don't play tournaments.
