You mean the CM.039C, AS&T? It's pig ugly but in a good way, I think.
As well as swapping the stock, I'd take the polymer RIS off it and replace with an aluminium one and put a PEQ equipped with an IR laser and IR illuminater on the left side and a 2 x 18650 XML T6 torch on the right; an Elcan Spectre replica on the top rail for day with a green laser on a 45 deg rail adapter off the left side just in front of the Elcan with mousetail down to the pistol grip, and when I can eventually afford it, an NV scope for night; AK Beta midcaps in clamped pairs; a custom 3xmicroswitch pressure pad heat-shrinked in a finger width spaced line attached to the foregrip to control the PEQ & torch; aluminium foregrip with a channel for the pressure switch.
Even stock, a pig ugly gun like that needs the right loadout: all black would do it, or shadow camo BDU's with black WAS rig, even ACU under a black rig would do it.
If you mean the CM.048 I mentioned before - I love it. It's the classic Russian Formed Arces gun - iconic for that, but also, especially with a GP-25 slung under it, it's so obviously a product of it's era. What's so interesting about this is that the aesthetic is 'form follows function' and yet it's so obviously different from the Bauhaus school. I find it difficult to describe without talking in overused cliches which completely gloss over the intricacies of what I'm talking about - which is ironic since so many of those cliches are about unsubtlety, proletarian lack of sophistication, 'brutality', impersonal, bla bla bla... and yet there we have the AK-74 gas block and the fluting of the wooden stock.
