Rebarreling Practice Upper (11/11/2007)

On Veterans Day weekend 2007, I rebarreled my practice upper, which is a Compass Lake Engineering upper that I bought second hand. The throat is fairly worn so I ordered a new service rifle competition barrel from White Oak Armament, along with some new parts (headspaced bolt, gas tube, front sight base). I also bought the upper receiver action block and DPMS AR-15 armorer tool for this project. Rebarreling is very simple. If I didn't take the time to thoroughly clean the upper receiver after I took the old barrel off, the rebarreling procedure would have only taken about 30 minutes.
