My charge handle pin keeps walking out
« on: May 19, 2017, 06:32:52 PM »
HBI Evo pistol length hand guard and the pin that holds in the charge handle in keeps walking out the left side, so okay I went up a size from factory 5/32 to metric m4. The step up to M4x24mm size was real tight when installed,but only lasted about 600 rounds now it's walking out.... once again, the left side... any ideas on a simple fix ? was thinking on trying to insert a split style roll pin inside the roll style pin to give it extra pressure but I get the feeling that will walk out aswell. Maybe use a tapered punch and bell out one side of the pin ?

Don't want to do anything drastic like peening the hole end closed on the left side of the handguard

Why not email HBi and see what they say/recommend rather then risking your handguard?

I did a few hours ago, I figured I'd ask around.

If it were me Id go and see if I could find dowel pin of wood same diameter then tack a very small nail into one end slide it into the forearm. Then after its through nail the other side. Its not permanent its billhilly but may work and be cheap(plus you could paint it black to match) until hbi gets back to you. Its a simple way to swell the ends to get it to hold is all.

damn, HBI is giving me a whole new handguard , can't beat that! I Think the hole went soft everytime you increase diameter pin it goes it real tight until about 300 rounds later you can push it in or out by finger


weird it waited until about 2600 rounds on this handguard , 3400~ total on the gun before this happened. I haven't changed handles or pins in 2600 rounds

More reliable than amazon, and it's a small business at that!

Hence why I posted what I did...they have been known to have excellent CS.

Will never understand why some are so quick to "shadetree gunsmith" their weapons...

So your calling my dowel rod fix- shade tree gunsmithing. I take that as a complement. LoL I know My idea was billhilly it was just all I could think of at the time.  I'd rather be in some shade than the summer sun. LoL

The friggin pin keeps reliably walking out of the left side after digging through my stash of dowel pins "solid pins" I've discovered its 4.5mm hole on right side and 4mm fit in loose on the left unsure why it started after 24-2600 rounds after install. I used a tapered punch to open up one half of the pin and seems like its holding for now, atleast until monday when new hg comes in. He mailed it last night after work and the new HG plus my 2 extended poly charge handles come in monday. HBI is not only better than amazon cust service they're also faster  8)
