T91 12.5 upper

[rchen404]

I want to buy one and price is right. But my regular upper had a canted front sight bus and had to be replaced by wolf. Even after replacement, rear sight has to be adjusted all the way to one side to zero.

I've seen some other posts on canted fsb so it doesn't appear to be one off issue. Too bad. Would be great with silencer

I feel you, as long as you are able to zero it, you should be OK.
