I know this was posted a long time ago but thought I would add some comments on longevity, I have had one of these since december 2006 now and overall it has been absolutely fantastic. However, there have been a few issues; firstly the body pins are pot metal and the front handguard pin actually snapped in half. Also, the thread on the front stripped after a weekend of use with a screw on silencer. However, for the vast majority of the time this has been a great gun.
