Lots of nothing?


this is the part I am talking about.

That is a case deflector. HK uses whats called a lens head rivet. I'm not sure what you have. I have snugged them up by setting the rivet heads on my steel work bench and got to the other side with a center punch and reset the rivet

 

Thanks, will need to think through this, how to tighten without screwing up the finish, odd to have this occur after 275 rounds 🙄

 

Any other suggestions on getting the rivets tightened, I thought about the suggestion above but I can’t seem to get a position that’s not going mess up the finish. I would like to get this done before my stamp gets approved if it will involve sent to a gun smith to fix. I am going to put a A3 stock on this one so I am sure fitting it is gonna mess up the finish, perhaps this one will get a refinish with the stock so It perfectly matches.

 

This is a lens head rivet. All you’re really doing is flaring it outwards. Just put a piece of hard wood or a piece of leather under it. It’s just a couple of little taps with a small hammer

 

There was a video on Youtube (which I'm sure was probably taken down because it was giving gun instructions) where a guy used a long armed tool to squeeze the rivets together. The tool looked expensive and for your needs, most likely a waste of money for a small repair job. The video got me thinking if a C clamp would work if the deflector was supported on the back side, but the rivet heads may deform.

Second option, I have done this type of guerilla or gorilla gunsmithing.

A two person repair/four hand repair. Find a long punch that closely matches the riveted face on the back side of the deflector. Clamp the punch onto a vise, but make sure it's long enough to make contact with one of the holes on the back side of the deflector. Use a machine bolt (the bottom of all bolts usually have a partially domed face) that matches the head of the rivet. Use a piece of electrical tape to either cover the rivet head or the dome face of the bolt.

Have one person hold the receiver with the back side of the punch lined up with the rivet hole. The second person holds the bolt on one of the rivet heads and uses a small hammer to tap the bolt. Bolt heads are gently tapped until the slack is taken up. You may get slight marks on the rivet head. Either touch it up with some paint or maybe a sharpie depending if you have finesse or a ham fisted gorilla (HAHAHA)

 

We think a like, I was thinking the same thing. But I think it will be easier to have a pro do it. I am thinking of canceling the stamp until I get this figured out. Freaking clones👎

 

Look up weapon builder and they make a rivet tool, should have one on the rental side for an easy fix.

I only need a 12-15ton press😂

I am gonna see if Ralph Jr. here in AZ can handle it, worse case I have to refinish it and if that’s the case I will withdraw the SBR stamp that has not been approved yet and remark it MP5 since it’s gonna be refinished, then do the Form1 again.

I think that’s cheaper than selling at a loss and purchasing another and hoping the same thing does not happen with it.

Glad the Stamps did not get approved yet.

Starting to lose my patience with good value clones😡

 

I don’t see what your issue with them
Is. 1/2 the price of an HK built unit and in most cases good enough for most gamers. I wouldn’t gauge a clone on a failed rivet though. That falls into “sh*t happens”. Now some of the AP5’s with blocks that won’t let the bolt carrier come out- that’s an issue.

 

I have 3, I just don’t have patience for the little issues anymore, I just want them to work. Now that being said, this one functions fine. No insult implied, most are issue free, I guess I want it all🤣 plus add in major OCD, 🤣

 

Well I gave it the college try, no dice, actually I think its worse🤣. So now gonna have a HK smith weld the rivets so we don’t have this issue, odds are that will require refinishing, oh well. It is what it is. Oh and the form 1 got approved this morning🤣🤣

That sucks, I wish it would have worked for you. Maybe it didn't have lens head rivets

 

What did you try?

 

Resetting the rivet with a center punch.

 

My technique has never failed. You will need another person to help hold the receiver and line it up while to tap away with a bolt on the rivet head.

 

I used aluminum barrel clamp as an anvil, taped everything up, put 20mil gas pipe tape over the heads of the rivets and rested the head of the rivet on the anvil. Had my buddy hold the receiver still, used a center punch and 16oz hammer. Tried a couple times, I got the rear rivet tighten a little but the forward would no tighten up and when I tried again on the front rivet the rear got loose again. Im out, it’s going to Ralph Jr, to weld them in place and refinish it.

Sorry man, that's frustrating 😕. At least it will be in good (actually great) hands, and you know you'll be getting a product back better than you got from the mke factory! I'm sure the refinishing itself will make it worth it. Keep us posted.

 

Idk if there's enough room in the receiver, and it's certainly unorthodox, but I wonder if a motorcycle chain riveting tool would work 🤔

I have one, just away until the weekend. I can check when I'm back if you haven't solved it by then.

Something like this:
