A question about Grizzly mags.

So, I recieved my order today. 12.5" Grizzly mag fed, and 2 extra aftermarket mags. In the box, there was one plastic mag, fully wrapped, which I assume was the factory mag.
Then there was 2 metal mags, in plastic sleeves, which I assume are the aftermarket?
Is that the difference between factory and aftermarket, plastic vs metal?
 
Mine came with a metal mag, which differs only subtly from the aftermarket one I received at the same time. In any case, neither work. The Grizzly fed fine for the first 30 or 40 rounds, but since then, it's almost impossible to get it to successfully chamber a shell. Jams every time. I'll bring it to my gunsmith, but I'm not in a hurry. When I discussed it with him, he said they're notorious for that.

That was my first Dominion Arms product. The next (and last) was a case of "non-corrosive" 7.62x39 ammo. I did a nail test, which was coated in rust after 45 minutes. Hopelessly corrosive. Dominion Arms is synonymous with poison.

I'm glad to hear it, but "fool me twice..." is a sentiment most of us can sympathize with. I do hope that my Grizzly can eventually be made to work, as the concept is terrific. A mag-fed Rem 870 clone? I couldn't resist.
 
Jam city

Agree totally. Mine won't feed reliably with either the factory mags OR the aftermarket mags. Usually jams feeding the first round...and often the last as well. Not something I'd like to trust my life to in an emergency.

We have sold literally thousands of cases of this ammunition and tests have been performed by ourselves and many customers. This is the only case I am aware of where this ammo was found to be corrosive. Not only this, for the nail to show signs of rust within 45 minutes of testing is astounding. This leads me to believe that either you got a batch of ammo where during production, a factory worker in Ukraine managed to insert 1000 corrosive primers in the loading machine which produced all the ammunition for your case of ammo or the environment you tested in was not stable (were you in a sauna?) and/or the nail was already corroded.

I would be happy to help you with any issues if you would email me at ryanj@canadaammo.com. We stand behind our product and if this ammo was corrosive, we would certainly make everyone aware. We have purchased ammo in the past that we thought was NC only to find out later it was corrosive and not only did we notify people, we also credited people who have already purchased said ammunition.
 
Can anyone explain to me exactly how the rounds jam?

Do they nose dive? How are they oriented?

this will help me determine the best solution.

When I notified CanAm of this issue, Dan told me the same thing, despite the fact that there was already a lengthy thread on this forum by another customer who discovered the exact same thing - a thread that CanAm replied to. So every time this happens, it's the only case CanAm is aware of?

I emailed Dan photos of both the corroded nail and the control nail, and of course the latter was gleaming. Day and night. The nail test was done in my garage.

You did stand behind your product, providing a full refund. Thank you for that. However, you did not inform anyone here to the best of my knowledge, and continued selling it.

Bottom line: If you care about your firearms, don't even think about running Dominion Arms ammo. It's not worth the risk.
 
I had the exact same experience as OP; two metal aftermarket mags and one plastic with the grizz. A buddy of mine has had one for a year or more and his came with a metal mag so it seems that DA has recently gone with a poly mag.

While I agree that the metal mags do not feed reliably, out of the box, a search on the forum will result in a very quick, simple fix. Ten minutes, mostly consumed in dis-assembly and assembly, and my grizz was feeding just fine. I just posted an explanation of it here.

Despite what the haters might say, its fun as hell to shoot! :ar15:
 
FWIW I had many problems with my grizzly mag feeding properly when I first got it, I thought It was junk, even emailed CanAm a video of it. Afterwards I gave it a really good cleaning followed by about 100 more rounds to break it in - its flawless now.

Thanks!! I'll try that when I get home.

They front edge of the shell catches on the bottom edge of the chamber. If you seat the mag (aftermarket, the DA poly mags have a different angle on the follower and feed reliably for me) well the shells feed but if the mag is pulled rearward at all then the first round is, 9 times out of ten, a fail-to-feed. As there is some play in the mag, it isn't uncommon that the mag isn't perfectly seated, especially after a quick mag change.

I would be interested in hearing how it works out for you. I went a little at a time and used some fired shells (with the crimp portion cut off) to test the cycling.

I'll let you know by updating this thread. I'm out of town right now, but I'll be home soon. Thanks again.
 
Ok. So if I understand this correctly, the aftermarket mags do not seat high enough in the magwell. This is causing the bottom lip of the shell to catch on the chamber.

That may be a solution, though seating them higher may cause other complications. I can tell you that the angle on the followers between the aftermarket and DA polly are different (higher angle on the DA poly) and that this leads to reliable feeding. The "bump" mod for the followers accomplishes the same thing and also fixes feed issues.

This is a picture of the DA Poly (in the back) and the aftermarket with the "bump". Both are being held firmly down on a flat surface and you can clearly see the difference in the angle of the follower.


I helped!! Do I get a prize??
 
I had my grizzly out at the range yesterday, I have two mags for it. The stock mag was metal, and the aftermarket was also metal of a near-identical design. This was the first time I was going to use the aftermarket mag, so I did a home test that morning and attempted chambering from full capacity. The first round was getting hung up on the semi-circular feed cut out on the new mag, and the follower was orienting the shells on a lower angle (as seen in an earlier pic comparing the two). I brought out a file and worked on that semi-circular cut out for about 10 minutes, making sure I kept everything rounded and free of burrs. After that 10 minutes, I wiped the shavings and reassembled the magazine. It fed that first round perfectly! Much better than sending it back and waiting. My action is getting nice and broken in now, my grizz is unstoppable and going bang every time.
