As Form said, it'll be done correctly for the application. The hard part on my end is feeding those dinky little things I'm not sure if everyone knows, but our standard short action has a 3.15"mag box.

Things are progressing on the project, sample bolt knobs heading out to Form for some proper field fingering.

I know Form is all bout the dbm. So you're saying, the internal dimension of the detach mag is 3.150"? That's a solid for anyone choosing to rebarrel, or (if you offer this) buy and action and dbm and build off it for a custom route. I personally love my crf ARC and zermatt actions. Would be very interested on building on this new MRF action.

3.15" is for the internal box. 308/Creed size rifles will be shipping with a flush 3 round poly, and 5 rnd metal mags (MDT). The poly is 2.85" and the metal are non-binders so they stretch to 2.96". Sorry for the confusion. Finding a 223 DBM with appropriate COAL has proven difficult. Once that's figured out, I'll have to adjust the mag height and bolt stroke for a proper feed cycle. Timing a DBM CRF is way more picky than a push feed.

We'll eventually be offering bare actions, but as it sits, machining the receiver is our manufacturing bottleneck. All available are going toward complete rifles for the time being. We've got some new automation planned for early 2025 that will more than double our available machining hours, which will help immensely.

Why not just build your own 223 with the COAL you want to fit your action?

Would your 308 pattern actions be compatible with the Unknown Munitions DBM allowing 3.15” internal on a DBM?

I know it can be done on a push feed action because my Pierce short action received is running one for a switch barrel 6.5 SAUM/300SAUM setup. Not sure if that would work with a CRF.

Are you utilizing the SRS/unknown dbm with extra long single stack box for these short mags then?

I would recommend a bottom metal for the DBM model that does not contain the mag latch inside the trigger guard. They are slimmer and snag free but dangerous as Hell with potential for an AD. Don’t ask me how I know.

If you were to make proprietary mags/dbm that were all metal, double stack, flush fit, like Sako. I’d be super impressed. Obviously the current availability of detachable mags, at proper length, for hunting is lacking. Having 5 rounds in a flush mag that actually works is a pretty big deal.

I'm thinking a 5rd flush fit dssf(dbl stack single feed) is physically impossible, especially with short mags. Now if you go dsdf(double stack double feed) essentially a 5rd aw mag, I think that might be near flush. I'm personally fine with 3rd down in a short mag, or rifle for that matter. I typically drop a 4th into the chamber and decock the bolt shut. Maybe not best idea, but it's never given me a reason to desire to change.

Yes basically a hunting style aw mag that holds 5 or even 4. Sakos hold 5 standard rounds.
