AR-15 Grip Screw Issue

I recently purchased a Daniel Defense V5 LW (free-float quad rail with 16” light barrel). I hadn’t had a chance to take it to the range, but being a lefty I decided to put some aftermarket parts on it to make if more lefty-friendly. One of these parts was an ambidextrous safety. I had swapped out my friend’s A2 grip for a Magpul grip, and messing with the safety was only one step further, so I figured I knew what to do, but I watched a guy on YouTube install the same part to be sure. It was to go as I expected. So the first step is removing the pistol grip. Simple, right? Wrong! I went about trying to unscrew the pistol grip screw, and it wouldn’t budge. I used a pair of pliers and a screwdriver, and I got it to turn about an eighth turn. Already, I had marred up the screw head, and the screw hadn’t broken free. It was still stuck. Go ahead and look at attachment #1. I checked the owner’s manual to make sure it’s not reverse threaded or had any hidden set screws holding it, and it said nothing about it, so I assume it’s normal. So I cranked on it some more, got it to a quarter turn, and… look at attachment #2. It still wasn’t broke free, and by this time I was very concerned. I looked around online, and I could find nothing like this. Flabbergasted, I took the lower to my LGS to have the smith take a look. He said, “Well, you just unscrew it,” as if I hadn’t tried that. He cranked on it with pliers and a screwdriver that filled the slot both length and width-wise, and see attachment #3. The smith concluded something was definitely wrong.

With the screw head pulverized, I called Daniel Defense. I spoke with a nice woman (Caroline, maybe? I’m not good with names) on the phone. She didn’t offer a definite reason for the issue other that it must not be built to spec, but in less than 4 minutes she told me she would be emailing me a UPS shipping label. She said they will take a look, and decide if it can be repaired or if it needed to be replaced. She said they warrant the gun for defects for the original owner (which I am), but she didn’t require any sort of proof of original ownership. I even asked if she needed any proof, and she said no. So there is a silver lining if you bought a DDM4 used.

As requested, I have shipped the whole rifle off to Daniel Defense. This screw issue has been rather disconcerting, especially since I have only ever heard good things about Daniel Defense. Obviously, I prefer to not have to experience any company’s customer service, but here we are! Feel free to ask questions, and I’ll update this thread in the future to let you know how this goes.

I have a DD and the grip screws are in there. I believe they did put some loctite on it. It take a large flathead that you can put a box end wrench on. Once you started to tear up the slot it was over. Not to sound rude but most problems come from people without the proper knowledge and tools watching youtube videos.
 
Flat head screws are the bane of my existence, with any screw you need to use the right sized screw driver to not wear the head out, but especially so with flat heads, as it easy to not use the right screw driver.

Get a good set of screw drivers or bits in lots of different sizes and you will avoid doing this again.

Oh and pliers or vice grips should be very very last resort and usually only when the head is completely stripped out.

I have two large screwdrivers that I ground just for grip and stock screws. If the driver had filled the slot it shouldnt have broke out.

Turn the selector half way between safe and fire, with a non marring punch strike the right side and the lever will move over the detent and out. To replace use a small flat blade screwdriver on the detent and push the lever in. This is a really easy procedure that takes but a moment.

A few things
  1. I cant beleive DD still uses flat head screws on the grip.
  2. Why the hell did they put it in there so tight and or use loctite that is not needed.
  3. Since your replacing the grip anyway I would have cut it as close as I could to the screw and used some locking pliers to get it off.

"Turn the selector half way between safe and fire, with a non marring punch strike the right side and the lever will move over the detent and out"

And THAT folks is how you bust a chunk out of your lower!!!!!!!!!!!!!!!!!!!!!


Initial problem with OP was incorrect sized screwdriver and lack of solid support of lower during first attempt to remove. Just my opinion.

This makes me glad that my bushmaster came with an Allen head grip screw. It made changing my grip a breeze. I would go to the hardware store / home depot ect and get a an Allen Head screw when you finely get the flat head screw out, and replace it with that. The Magpul grip I switched my stock one with had a flat head screw that came with it and I opted to keep the Allen Screw after reading this post.

Mobuck, your comment is stupid, it takes just a tap on the punch and ithe detent rides over steel without stressing any other parts. This is a common procedure in military armories and broken receivers just do not happen. Try the procedure before making unsubstantiated remarks.

I got the rifle back yesterday. According to an email I got from DD they got the old screw out, "tap[ped] the hole to properly accept threading," and put on a new screw and washer.

I would love to tell you more, but there is another pending issue. More to come later!

Ib, I'll stick to removing the grip and detent. I stand by my comment regardless of your "obvious expertise". No need to get personal so I'll let your gouge pass w/o response.

Not in any disassembly procedure that I have ever heard of.

This would include:
THREE military arms rooms;
TWO Police Departments as an armorer;
TWO basic Colt AR15 Armorer's classes; (factory approved)
ONE advanced Colt AR15 Armorer's class (factory approved)
ONE business of my own as a general gunsmith, and

37 YEARS experience working on the AR-series platform.

The proper disassembly would include: clearing the rifle, separating the upper and lower receiver groups, removing the hammer pin, hammer and spring, then unscrewing the grip screw. With the lower receiver upside down, carefully remove the screw, and then the detent spring. Turn the receiver group right side up with your hand cupped over the detent hole, and catch the detent (known affectionately as the "bullet pin"). Now, remove the selector lever.

Here's a question about grips and warranties... Does changing the grip void your warranty?

Just curious since you'd be putting "aftermarket" accessories on the rifle.
