A few weeks ago I bought a new AR upper with a free floating handguard. All was good until yesterday when I discovered the the handguard was unscrewing - the lock nut had loosened. I'm not sending it back for this simple fix. Unfortunately the wrenches I have do not include the correct nubs for snugging the nut up, and I need to buy the right wrench.
Looking at the brownells and midwayUSA webpages show a handful that will work, but the reviews on most are very bad. Most say the nubs snap off, they mar the gun, etc., they all look equally bad.
So I turn to the pros here, which one is working for you?
