I'll see if I can get better pictures. If I recall correctly the adapter locks fine into place and is flush with the bottom of the receiver. I will take a look and double check (I'll have to dig it out of the back of the safe, I haven't touched it in a year and a half). I'll see if I can find my order information, it has been about two years.

Pics of install? Mag type used? Sounds like your rounds are nosediving. If this is the case (and assuming your measurements are correct) the follower is tilting as it's stripping rounds (bad mag follower/design). Try a different mag. Not dropping free is touch and go depending on mag manufacturer, something we have no control over. As stated before as well as on the sheet we recommend PMAGS. They are STANAG compliant and consistent in quality and reliability (non tilting follower). We've used many mags for testing.... USGI surplus and PMAGS is what we recommend. we used a mill an

I installed mine following the instructions with multiple measurements. It feeds most of the time but will have some hang ups. I have not installed a bullet guide. I bought two for my two rifles but only installed one due to the feeding issue and magazines not dropping free. Not sure what I am going to do with my adapters now.

How well do mags drop free? I have two of the old adapters and neither allow the mags to drop free especially pmags. So I am hesitant to invest money in another adapter.

I have shot 4 different brands/types of shells through my drum mag. The only problems I have encountered were with the 2 1/2 shells. (It is made for 3 inch) I have about 150 through it now and have had no problems with the 3 inch shells.

Looks good, what fore end is that?

The four I tried all locked tight into my gun. I have to take a little off the back locking point to make it easier. It has a little up and down movement in the front but that is it. It may just be the difference in guns.

These drums are awesome. I've put almost 100 rounds through mine. I just wish they would make on the same size as the 12 round drum. Now I have to buy a reloader for .410 because it is far too expensive to blast through 30 rounds at regular price.

Both of the hang ups where on the bottom of the feed ramp (Chamber was probably the wrong word to use.). It appears that if they would have been tilted a little more or a little longer they would have fed just fine. It deformed the front edge of the shell pretty good. I have them kicking around some where I will see if I can find them and post a pic for you.

I already have a 30 round drum. Oh wait that is for my 410. In the 12 gauge I would rather have a double stack mag. Now if they could make a 20 round mag the size of promag's 12 rounder that would be awesome.

So I have shot almost 100 rounds through two different promag drums. Here is my short review. Both magazines have functioned flawlessly with 3" rounds. I did shoot about 20 2 1/2" rounds through one and had two FTF. Both of these rounds got hung up on the bottom of the feed chamber. Like many mags there is a little bit of fitting that my be required. I need to shave a little off the back locking tab so it will lock in easier. The magazines are a little bit difficult to load because you have a smaller surface to push down on, it is not unmanageable just a little difficult. The siz

I hear you on the price of shells, this had given me the added push I need to start reloading .410. I haven't crunched the numbers yet but my vague ccalculations indicate it to be quite a cost savings.

I was just concerned about 922r compliance. I did go test these out today after a hasty conversion. I shot 3 inch and 2 1/2 inch. The 3 inch (20 rounds) all fed fine with out a problem. The 2 1/2 had two FTF. Two shells caught on the bottom lip of the feed ramp. I had the same type of FTF with my Saiga 12 when it was under gassed, but that does not seem to be the issue here. I don't know if a little tweaking would fix it for the 2 1/2 shells or not. I do have to say it was quite fun blasting away with 20 rounds at a time.

To be honest, I was too excited to get one that I forgot to ask.

I don't know if they are beta drums or not. I had seen them at a gun show back in the summer but I did not have a 410 yet. When I asked about them no one had seen them either. Cobra has been saying for a while that promag was going to make some but no one on this site had seen one. So there was a gun show this weekend and I was able to find the same vendor an buy a few. They hand cycle fine but I have not shot one yet. There is a little bit of up and down movement in front of the mag where it locks into the mag well. It is pretty tight on the magazine catch on mine and I will probabl
