EVERYTHING! this is the best trigger on the market by far!
Nothing, its perfect
If this trigger was 300$ i would still buy it, its crazy fast. The trigger pull is rediculously short, you can almost blow on the trigger and it will shoot. I was shooting about 12 bps with the Adrenaline Trigger which is magnetic, now i can shoot 18 bps easy with the
I-Frame. Best FRAME EVER! Buy it and you wont regret it!
