Magpul MOE Handguard + loose vertical foregrip question
After purchasing my AR15 a few weeks ago, I've since outfitted it with some Magpul furniture, such as the pistol grip, handguard and vertical grip. One thing I noticed was that after installing the vertical grip, it seems to loosen up after a while to the point that it has a slight swivel. It feels stable enough, but I was wondering if this was normal or if there was something wrong with the handguard/grip or the way I installed it. Anybody have any experiences?
