I had Primary Machine do my 07 and I had the sights installed in front of the RDS. I have nothing against Jagerworks I know they do quality work. I picked Primary Machine just because I guess. Anyways I would look and compare prices between the 2 and see what sights they offer between the two and go from there. Mine are just plain black suppressor height sights, nothing fancy. While I wanted the back up sights for a just "in case" scenario I NEVER use them, maybe if I've turned off my RMR and end of shooting a couple extra rds but like they say better to have them and not need them then to need them & not have them. I think worse case if your RDS went down and you looked through the lens/screen I wouldn't be worried about hitting my target,LOL ! All about practice but yes the BUIS would be beneficial in that situation !
