I’ve picked up the newer M2 model and was looking at aftermarket charging handles from Taran Tactical. They say it fits the M2 but doesn’t say the newer model or older model i’m assuming it would fit since not much changed over the older and newer model. I’ve ordered it so i guess i’ll just find out. I’ve also ordered a trigger spring and hammer spring from TT ( Taran Tactical) and i’m guessing it’ll fit the newer model to since the only thing that’s changed is the comfortech stock and bolt release and other small things. But does anyone know for sure?
