I sent the stock for my CZ 457 MTR to a guy to install an adjustable cheek riser, and it arrived back today. When inspecting it, I noticed a hairline crack on the left side of the magazine well. It's all the way through the stock and if I flex the stock, I can see a gap. Is there any way to save this stock? Perhaps something like bedding it? Or am I going to need to replace it and start over with the modifications?
