Makes the front pivot pin detent and spring a 10 second job. The Magpul Armorer's wrench - $75 - is the best AR assembly wrench on the market. A good set of long shank gunsmith punches saves time and makes the job easier (get an extra long shank 1/8 punch, it's the "trigger and hammer assembly tool"). A barrel extension and a upper receiver vise block are great for working on uppers. With a few specialty tools and some practice you can assemble a lower from scratch in 20 minutes, an upper in 30. Uppers are more complicated than lowers because alignment and torque wrenching take more time and have to be done just right. Waynenoreply@blogger.com
