Since CDI is out of business is there any other routes to go for a DBM? Thank you.

Part of the problem with CDI’s system was it wasn’t a drop in kit like HS Precision or others. Rifles had to be sent for fitting. This was more than minor dremel work needed. I believe they were trying to build a good product but hadn’t worked out the R and D issues before advertising.Since CDI is out of business is there any other routes to go for a DBM? Thank you.
I considered the Atlasworx bottom metal but didn’t care for the shape of the trigger guard. Right now it’s still factory polymer. My friend has one and has zero complaints. I wouldn’t have a concern about safety. Hopefully something better will come along, but I’m not holding my breath.Sean Hodges,
Have you used Atlasworx out of Australia? They have shrouds and I am thinking of ordering a metal floorplate from them as a place holder until I find a dbm.... Do you know if they are safe?

The shroud is a genuine Sako 85 stainless steel. I ordered it from Midwest Gunworks. It was less expensive than the Atlasworx aluminum. It dressed up the bolt nicely. The fit and finish is superior and it was plug and play.
My friend bought his Atlasworx bottom metal through eBay. They have 100% positive feed back there if you’re concerned.Good deal, I was worried that I would get burned by them. I may order the parts from them. Thanks for the info.
The factory A7 magazine is way too proprietary as is the magazine release system to use any aftermarket magazine without major and radical modifications. I’ve recently looked at nearly everything available and nothing I’ve seen will work. I seriously doubt anything reliable or reasonably astetic could be accomplished.Finally got my metal trigger guard from Atlasworxs Now, there has to be a way to use other magazines than the factory plastic ones!

So are you perhaps considering buying an Atlasworx bottom metal kit with the rear release, then removing the factory magazine release. fitting the bottom metal, then potentially using a 5 round AICS magazine? If so, it sounds like an interesting concept.The concept of their magazine release is not that different from say other Atlasworxs DBM's. While the release system is at the back of the magazine on the those DBM's, the Sako A7's put it at the front of the magazine but almost the same concept(minus the drop free part). Another concern would be the positioning of the tip of the cartridge in relation to the feeding ramp(see https://mdttac.com/ca_en/mdt-metal-magazines-short-action.html), but I'm hoping the binder of an AICS magazine would take care of that. I just need to get my hands of one of those 5 rounds AICS magazines that fit into the bottom metal and see what's missing.
Another fun fact is that the magazine release system is connected to the receiver, and it looks like it can be unscrewed, so a DBM can be developed for the A7 without any obstacles inside.
Sigh.
Actually I wanted to start with just modifying a magazine, but the second option should be explored too although making an Atlasworx Tikka DBM(for example) fit the A7 might not be as easy as it sounds. My friend has a Tikka CTR, I'll have to take the measurements of his factory DBM and see if closely resembles the ones of the Sako.
How is your A7- PMAG project coming along?
The project is on hold for the time being. In the process of moving across the country, so I had to pack the printers up. Likely will resume in the next few months when I am resettled.
My prototype is functioning well, but durability is a concern especially on the feed lips. At this point, I'm mainly researching other methods/materials to give the magazines more strength without making the overall cost prohibitive.
