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.
