I'm going to agree with Bullseye (keen eyes) that it started around the front locking lug. It does appear to go to (or from) the inside Nope, the cracks start at the bottom outside where the flat is milled. One has propagated to the inside.

MK III uppers cracked

For a few years now, I've been telling people not to worry about Ruger MK III's. I believed they were the same as the MK II but with a few extra pieces. Yesterday, that opinion changed. Our range has two MK III's and a Mk III 22/45. These were bought about 2 years ago and see a lot of use. All three...
