No more adapter plate is needed to mount the Romeo 3 Max/XL!
We have developed a direct optic cut so you can run the best optic on your Sig P320 X5 Legion Directly!
This will work on any version of the X-FIVE slide, we just micro laser weld each version slightly differently. This includes the original version with the old smaller Romeo1 footprint through the R2 Legion.
First, we micro precision weld up under the slide where the M4 hole will be located. Next, we CNC cut the pattern at the existing optic cut depth.
