the function feedneck works great, really locks tight. and matches the gun color perfect. a 10! the trigger, i love it, made of delrin, very smooth. a little different on feel, if you are used to a stock or blade trigger. i dont like blade triggers. just my opinion. again, the trigger works great with the color scheme. another 10. i'm real picking on color and feel. these parts work great for me. i also went with a cp rail & on-off. they look great on the gun, and i think every gun should have an on-off. FOR SAFETY!!!!!!! again, i give a 10 to cp. hope this helps.
