I got a new AR15 upper and need to swap a AAC muzzle brake onto the new upper to run my M4-2000 suppressor. I had a little bottle of ACC rocksett, but when I went to use it the bottle was all dried up.

Does anyone in the Pittsburgh area have a little package or bottle of it? AAC sells it, but it is over $13 shipped for one package and they wont ship it until Monday due to the holiday.

If anyone has any let me know. I was hoping to try my new upper out this weekend. I will pay for the bottle.

Thanks
