  • I ordered this handguard recently and have been following the install instructions exactly but the barrel is not centered in guard. Every time I tighten the clamp set screws the guard adjusts and the barrel angles towards the bottom of the opening. I’ve tried tightening it all different ways but can’t seem to get it aligned. Any advice for ways to get around this? Or something I could be doing wrong?
