After making my Primaris Assault Centurion squad I wanted to also have a squad of the Devastator Centurions.
I chose the lascannon fit out as after all these years it’s still my favourite heavy weapon.
I used the same approach to build as detailed in my how to post that was a pretty easy way to increase the size of the bros up to primaris size. I made the sarge a little taller than the other bros and used the Mohawk bit from the original kit.
All the heads are from the primaris lieutenant kit.
Painting followed my Sternguard Veterans approach which had more of a bone white colour. Finishing off was a heap of transfers and the bases using old bark as rocks and astrogranite textured paint.
Here is a size comparison next to a primaris marine.
