Recognize this bottom metal/ magazine pattern?

[10ring1]

Picked up a 1991 Remington 223 that was upgraded with some bottom metal. Was going to make it into a trainer in time. But for now going to shoot it as is. Wanted to get few more magazines. Anyone recognize this magazine pattern? Thanks

Looks like a Seekins.

Looks like it but this one engages the magazine with the rectangular hole in the side of mag. Not from the rear where Aics pattern mags engage

That is a weird magazine- can you see if a regular AR pattern 5.56 magazine will work in your rifle?

I did try that but it was too wide. This could potentially be an older bottom metal with proprietary magazine

that's a seekins DBM when they were making their own magazines

Thanks.. so the chance of finding a few magazines is going to be slim I'm guessing...

Yeah, I haven't seen those in years. Have you tried contacting them or modifying an existing magazine?

Was thinking about cutting a rectangle for the catch engagement in a different magazine....or just getting a krg bravo and using new mags
