I work for an LGS, we have about 7 -8 Core rifles in our shop, they'll sit on the self for a while because we don't push them like other quality brands. People always ask me Piston or DI, I say it depends on your needs, but for the most part a DI will do just fine. I've seen the articles and heard everyone tell me about how much DI guns jam but I haven't seen it myself. If you only shoot 350-500rds per year the Core will be just fine for you. If you shoot more than that and push your rifle to perform under conditions other than a lane at the range then even a piston gun might not do it for you. A gunsmith once told me that the more moving parts the more that can go wrong, I would tell you to sell your Core and find something different.
I perfer black coffee in the morning, bourbon in evenings and spending money on sh*t I probably don't need.
