I got this trigger to dial in the "sweet spot" of my responce trigger, which it did perfectly. now i don't know if they didn't intend it to be used with the responce trigger but it snapped in half at the trigger stop adjustment screw after about only 8 games. at the time it was the only other trigger for the a-5 without an e-grip, yet had adujstments. for now im happy with the stock.
If you realy feel like wasting money on a cheap p.o.s. try it, other wise there are allot better triggers for just alittle more$
