I have a CM 040C and I found I needed to file it a bit to get it to fit. It fits now but my stock is a bit off center. It doesn't change how it feels and it's difficult to see so it doesn't much matter. It is also a bit wobbly, I've put some double sided tape in to stop it wobbling as much. It works fine overall, just needed a tad off filing and is a bit wobbly. It is worth the price.

Really nice on a cyma AK it’s a little picky with stocks but it’s good

Idk if I got the wrong one or something but it’s too small to fit my e&l. Fits my cyma tho….
