A guy at work bought one and wanted me to check it out. I have a Saiga 12 that I converted to side fold with a pistol grip, and was comparing materials and workmanship on these two guns. The STG 2000 seems really light and the furniture is a little flimsy. He hasn't shot it yet and is really disappointed with the handguard setup, which is the weakest point, cosmetically, on the rifle. It is a proprietary design that is not interchangeable with standard AK handguards, and worse, has a non standard handguard retainer that is dogshit at best. I found a lower retainer, & I've been searching my balls off for some AK handguards that include the upper handguard retainer, but can't find it. Does he need to buy a whole new gas tube?
