Shark Arms has A1 Fixed carry Handle Uppers

[calicojack]

So I did order a used upper receiver that was supposed to be taken off an M4 from Shark Arms. It has the correct color and forge markings. No cracks or anything. Very clean. Built an upper for my son. No problems with that. But based on the thread at AR15.com it looks like the out of spec issue is a big deal. Even if you shim the rear sight, it will not lay flat when you flip it to change the aperture.

I am cancelling the order.

I had great luck with Shark Arms in the past, but something there has changed in the last few years. Based on some of these recent reviews i would be hesitant to get anything from him now.
