Only some suppressor height sights seem to allow back up use depending on your MRDs.
This is one reason I’ve held off on getting a G34 MOS - that and waiting to see if the Acro lives up to the hype. Oh, and, to mill or not to mill.
Trijicon Bright/Tough Suppressor sights with an RMR on a G34 MOS
I used the Dawson Precision blacked out rear and blacked out front. They have different height sights to co witness with different red dots. http://https://dawsonprecision.com/sights/sights-for-glock/dawson-fixed-sight-sets/mos/
Ameriglo black steel sights w/rmr 07 Type 2
I tried using the ameriglo’s with my deltapoint but they won’t clear it on my 19 mos
Ameriglo has sets ranging from 0.394 rears, which are barely usable with my Octane, and not useable with most RDS,
To 0.598.
They also have 0.429, 0.451.
I find 0.507 a touch taller than I needed with this set up. Maybe 0.451 would have worked.
Dawson has 0.395, 0.420, and 0.495.
Trijicon has 0.361.
Overwatch Precision has some new suppressor/MOS height sights available, as does 10-8 Performance. I am debating between these two sets for my Gen5 19MOS with RM06.
I needed the Ameriglo .507 to clear on the 34 with the Venom. They are tall!
Tell me about it.
