DD lower parts

Everything came as advertised. Fits very well and looks great. You can tell right when you open the package that the parts are quality. Would purchase again for my next build

Fits Perfectly

Got the DD parts kit for the quality and got everything I expected. Parts fit perfectly in my Aero Precision lower and the grip is the best I’ve ever had my hands on. Ended up not using the TCG, instead got a drop in so I’m not sure how smooth the trigger in the kit feels. But everything was A+
