Yep. If you have questions just start a post! Upper,barrel,barrel nut, handguard, gas block, gas tube,torque wrench. But you need a vice and vice block for the upper. 30-50 foot pounds. Done. I put mine on 3 times just to make sure. 9mm ones were easy, no gas tube to fool with.
*** cheaper to buy one used, my .02 or buy a whole pistol and sell the lower.
