So everyone is on the same page,

The military awards their magazine contracts to small business. This is kind of like a start up contract, and once the company gets too big, then have to let the contract go.

IIRQ, “La Belle Industries was a division of Quest Technologies Inc (cage code 90435), and Quest Technologies/La Belle Industries may have lost its small business status and been forced to sell their dies to another manufacturer. The guess is that La Belle was sold to/is now D&H Industries (04TQ4).”
And, this is the company that is selling bodies/full mags to quite of few vendors to sell off as there own (wither marked or not as D&H mags).

For the most part, once the machines are set up and running smoothly, everything comes out like it spec'd to (mil-sped'd).  What may be happening is that either some of these mags may have been produced at start up/set up, and just quite not right, or there was a surplus sale from D&H with slightly out of specification mags that may have not been up to military standards.

Either way, if you have mags that are non-military specifications but quoted as being such (read defective stamping, forming, or welding) give the supplier a call and have them exchanged for true mil-spec units, or your money refunded.

Also to be sure everyone is one the same page -

D&H would not knowingly sell out of spec anything. We sell a large volume of products that are produced totally or in large part by them and trust their integrity without question.

Here is what we know - This relates to DSG branded magazines specifically - questions about D&H branded mags should be posed to your dealer or distributor. We have no information about what other dealers may or may not be doing...

1. DSG's mags have not experienced any widespread problems as threads like this would lead you to believe. Customers of other dealers selling magazines on this site could be seeing a significantly different product I suppose - but I would certainly question how that could occur.

2. We test fire samples from each lot regularly - normally 6k to 12k rounds per year - including a 900rd+ re-test Saturday - specifically of lots quoted in this and all the sub threads posted on this site. We did experience a weapon with cases sticking in the chamber, a broken bolt catch on a factory new rifle and even one broken VFG - but no mag function issues. All mags tested were factory built and QC'd with GenII followers. 4 weapons this time - 3 ramped and 1 new, previously unfired, non-ramped upper. Results were the same across the board.

3. The date codes being quoted here were large production runs and only a small percentage would be seen by arfcommers - the idea that the whole runs were problematic is not correct. Most of our product from those runs went into use straight away - not into storage or inventory.

4. I will confess that we do not hand cycle weapons with live ammo to determine function. Testing is live fire only.

5. We have seen a demonstration by a customer of how a new mag with 30rds loaded can stumble on dry feeding  - especially on a non-feed ramped weapon. This can be exxagerated by a well used buffer spring competing against a new mag spring. So maybe a sharp edge is the answer to these posts, but again our live fire tests and overall customer feedback do not indicate a function problem. The sharp edge issue has been addressed to our mfr. If we receive any useful info we'll pass it along.

5. We do not reload and do not police our brass so maybe the scratch people are reporting has been there for quite some time - possibly forever. Not something we have been looking for.

6. the original poster - billclo - has now reportedly received replacement mags from his dealer of a different brand - after basically trashing D&H - and now has a similar post started here discussing problems with this new brand as well - he's leaving out the brand name this time to avoid more misinformation. A good idea IMO. www.ar15.com/forums/topic.html?b=3&f=66&t=275178

7. If any customer has a mag purchased from us that won't make your weapon go bang every time - and I don't mean having to file or grind on anything either - send us an email with your order details and we'll take care of you.

Any of you guys that have done business with us know we shoot what we sell and stand behind what we sell - and other than questions from concerned customers raised by these posts - we have no issues to report... If there is a live fire function problem we want to know about it.

I do not presume to know what your problem is, but a large number of a 50 mag lot purchased that will not function in a weapon is an odd thing - in any brand. Doing it a second time with a different brand is even more odd.

Its not that I think you are intentionally starting trouble, but I do think you have another problem of some sort - possibly over thinking your mags - and your cross posting into every other thread insinuating that D&H mags are selling bad lots of mags just fuels the BS. Users that have less experience will sit at home and hand cycle a mag and think its bad - they read it on the internet.

You don't need feedramps - BM includes the same mags you returned in every weapon sold.

These are mass produced metal stampings that cost .mil less than $10 so to think there's never a problem is wrong, but as I told you in another D&H thread you jumped on - to assume D&H puts out an inferior product is also incorrect.

I see FALARAK tagging up - maybe he can let us know if he's test fired his yet...

Quoted: Rusty, I'd like to address some of your points. #1. I'm glad you haven't been seeing widespread problems. It's not in our best interest that there are. I understand you're just trying to protect your business interests; perfectly reasonable that you'd want to be SURE there was a problem before talking to D&H. #4. Normally I don't manually cycle the mags either to test function. I just load them and go to the range. But when one is at the range, and encounters problems even getting the mags to load the first few rounds (and therefore can't live fire test properly), it tends to raise eyebrows. #5. Unfortunately, not everyone has a M4-feedramped gun. Bushmaster doesn't make them to the best of my knowledge, and both of the rifles I tested the mags in are Bushmasters. One has about 1500 rds through it, and the other has about 1000. Not exactly old worn out guns or crapola quality Frankenguns. I have on the advice of some folk, ordered up new buffer springs and will report back after I get to test them. One gun I could see, but 2 guns is stretching things a bit as far as co-oincidence goes, IMO. #6. I have done my best to be strictly factual, and am certainly NOT on a rampage to trash D&H.  If you would, please show me where I've not been factual.  I've never said that ALL D&H mags suck, just that their QC may be stumbling some, and that I don't trust the product right now. If I were deliberately trying to stir up trouble, I certainly could do a better job. I can't control what follow-up posters have to say. If others weren't seeing the problem too, then my thread would be pretty short, or every response would be "you're crazy, they work fine in my guns". As you point out, the number of people saying they have problems is fairly low. But when they're YOUR personal mags (and spent over $500 for them), one tends to get a bit testy about the whole thing. And if it were 2 50-mag batches bad with one particular gun, I could see one thinking it's the gun, but with 2 guns, same manufacturer?

I have no way of diagnosing your problem over the internet and my comment about 'over thinking' is a common saying around here and means only what it says - some things are not that complicated. No personal offense intended I assure you...

FALARAK did come and let me examine his mags - and I was glad to do so. Had you been here I would have done the same for you. I feel confident you would have left with a weapon and mags that would operate and you could be confident in.

Don't misunderstand me - I am not tryng to get personal, but when a user starts a discussion and then posts in other discussions that cast doubt on a product that we know to be functional - and then receives another brand and begins again - there is something else wrong IMO.

Quoted: Rusty, I don't know what else I can say. I posted my experiences with the 2 brands. I didn't see you at either thread helping me diagnose the problem. If you're so knowledgeable, why not share it with those who need diagnosis of our problem - instead of insinuating that we're basically not right in the head? Is it normal for one to not be able to get rounds to feed into the gun. On the range now, not in the basement hand-cycling? Is it normal for the second brand to leave huge marks on the feedramps, hang up, and leave major brass shavings in the chamber. I posted good pics of the situation with the second brand, and even followed the advice given there. I can only conclude the second brand isn't up to par. As soon as I switched the supplied fresh springs/followers from the new mags into known good GI mags, the problem went away. It isn't the buffer springs on both rifles. Gotta be something with the mag bodies, as that was the only variable. I even contacted the maker of the second brand, sent pics of what I was seeing, sent pics of the feedlip are that I thought wasn't right, sent pics of a typical GI mag's feedlips. I asked him point blank are the feedlips supposed to be this way? If so, why are these lips rubbing like hell and causing misfeeds? Or if they aren't right, what shall I do about it? Never got an answer after asking twice. He danced around that issue entirely. It's kinda like buying a car because the company has a great rep. You have nothing but trouble with it. Everyone says "nah, they have a good rep, you must be doing something wrong". But I bet it sours you on that brand and you wouldn't buy one again. Same situation here. From my only experience with D&H, they aren't so hot. Compared to all my other mag brands: Center, Adventureline, Parsons, FN, they ARE inferior. I've had over 60 of those brands run right out of the package, no tweaking needed. No dremeling, no filing, nothing. Since you seem to want to get personal, insinuating that I'm"overthinking" the mags, and are perhaps nuts, how about this: Other people than I are reporting actual problems with the mags at the range. My 2 guns run great on regular GI mags, and not these 2 brands. Just because they run 100% in your modified guns doesn't mean shit. FALARAK showed you that in person. I think the issue is that because you have a vested interest in D&H mags (since you sell them), you tend to overlook the issues others report - they don't fit your experiences with them - and it threatens your bottom line. I gain nothing by bashing either company frankly, except hassle and expense having to deal with their product. I'm going to stop participating in these threads now, since I've gotten alot more flak than support it seems. I don't know why I even bother raising questions anymore. I must just be nuts, yeah that's it.
