I am selling my complete upper with about 700 rounds through the tube. I am wanting to sell this to fund a new upper build. This Upper has functioned flawlessly. The BCG, Charging handle, rail system, and entire upper was assembled by the fine folks at J&B. I paid 430 bucks for the whole package. The upper is used so I would take 370 or best offer. Just let me know if your interested. I have a inexpensive scope mounted on the rifle. The optic will come with the upper for 350. Anything less and i will just hold on to it. located in beaverton.
