Keyhole A2 upper wont fit any of my lowers???.....
Not to familiar with all the differences in AR's...
I have a newer bushy lower, older, and plum crazy, NONE of which the A2 upper will fit on....
It has the Keyhole marking, and I assumed it would just fit right on....
The rear pin goes in, but the front goes half way, then gets stuck.....
Front pin first then the rear.
Sounds like the Model 1 Sales upper that I have, fits tight on all of my 13 lowers.
+1 on the front pin goes in first, better tight than loose.
Just did not want to force it!!
Thanks guys, maybe I will work it in a little.
My Nodak Spud lowers fit tighter on my upper receivers as well. Just pin the forward pivot pin and hammer down on the rear take down pin.
