M&A 16-inch upper

[jtr]

Just wondering if anyone has used one, what your thoughts were on the M&A parts 16-inch upper.

Interested in the standard CAR type upper - just something to add a red dot to and plink. Figuring on using supersonic handloads (110, 125, 150). Have a 10.5-inch suppressed upper and Rem 700 on 300BLK already.
