I am looking for a AR15 flat top upper receiver
which does NOT have a forward assist boss
and does NOT have a case deflector bump.
See attached pic.
(Not looking for 9mm bolt, barrel, rear sight, delta ring, hand guard, etc.)
This is known as a "9 mm upper" since
the 9mm bolt carrier does not have the ratchet cuts needed for a forward assist to work,
and the 9mm has a different, half-moon plastic case deflector as compared to the
built in aluminum "pyramid" typically found on 5.56/223 uppers.
Yes, Rock River has them at $175 a pop.
Brownell's has real colt uppers at about $160 a pop,
complete with the visible remnants of the crudely machined off forward assist boss
Thanks!
