Anyone running a 12.5 upper?

[Shiftyk5]

I’ve had 3, all worked well. Had a PSA stainless 12.5 upper. A Monster group buy 12.5 upper that I put together and my current Lilja 12.5 upper I put together. All very reliable from what I used them, the PSA and the monster barrel shot damn near identical. They preferred the federal AE 90gr TNT factory load the best for a factory loading and hand loads liked the 129gr ABLR or the 120gr ELD-M.
The Lilja seems to like about anything so far.

You should get one, you will enjoy it.
