Fungun's Review of ArmaLite AR-10 A4 B-Series Upper Receiver Assembly 7.62x51mm/.308 Winchester 10002001

Just want to say the ArmaLite 308 upper that I received was fully assembled and ready for mounting a barrel of choice. Fit, finish and color was a perfect match to my ArmaLite lower. Installed a mid length 20” ArmaLite barrel with a flat top front sight rail for the fold down front sight along with a fold down rear sight as back up. This flat top upper is a great addition to the rifle for mounting any scope you choose too. Opticsplanet had it a a great price too.
Pros:
  • Allows a scope to be mounted in a variety of positions, relative to the eye.
Cons:
  • non
Best Used for:
  • mounting a scope
Would Recommend: Yes
