They're just too expensive for how many quirks they have. Tommybuilt type shit. Sure they offer kits for some guns that don't have good GBBRs to be host to HPA for but the break-in period on top of the particular regulator+hose setup I had to put together to get it to work made me not like it. For the price they shouldn't have so many problems. The people who are fans of them are evangelical about it and typically don't have much xp with any other system.

I wanted one before they discontinued it. Seemed like it would be a bit more robust but I guess they didn't believe in it.

Let me guess, you need more?
