I have the fixed front and rear, they are phenominal. Incredibly easy to mount and sight and insanely strong. Ive dropped my gun with them on and theyre still holding zero. I will say, if you buy the front sight and are going to use the add on options to add the rear sight in the notes mention that you ordered the rear sight too. Mine showed up without it but Midwest Industries was amazing and had it sent out and to me in 2 days. 100% recommend.
