US
Nice rear sight parts for an A1 Build.
This set fit perfectly on my A1 Upper and I am very happy with the quality.
USLuth-AR A1 Rear Sight Assembly
used it on the M16A1 Stripped Upper Receiver - M4 Feed ramps, fit perfect for my retro build
USLooks good!
The installation was fairly easy, but you really need a second set of hands to dress the sight wheel while installing the roll pin.
USWorks great
Installed this in my NDS receiver. Fit is tight and I can wait to take it out.
USDirect replacement
Broke the OE DPMS part and used this to replace it. Fit perfect.
