Hi Arlonta, the Black Aces Pro M series semi auto shotgun is not an exact Benelli M4 clone. The Black Aces S4 is a Benelli clone.
Besides, how can it be a clone when one is magazine fed and the other is tube fed? So, the Benelli M4 pistol grip may or may not work.
You can either get a “Turkish shotgun adapter” and put any magpul grip you want on it, or buy a “Turkish shotgun pistol grip”.
