RRA 16" 9mm A-4 upper looks just like the lower one pictured here with bayo-lug and f/hider.
this is a complete upper.
low mileage also included are 3 Pro-mags $425.00 delivered. nice shooter but have other projects more pressing
ALSO FS: 9mm bottom load mag block with bolt hold open. BHO works with colt or pro-mags only. will not work with RRA converted uzi mags.
buy both for the package deal. $525.00 delivered with 2 uzi mags thrown in!
while RRA suggest you use a 9mm buffer and hammer. i had no issues using my carbine length buffer. i do have a round .223 hammer in my lower and this upper shot very nice w/out any issues.
