IRM, here I come. Only thing I wish were avail from the factory was a barrel length option. Don’t mind paying $3k but a choice between a 10, 16, or 18-inch barrel would be a nice touch. Either way, thrilled this is happening.

Maybe I missed this, but what barrel length comes with the upper? I'm hoping it's in the 10" range, but the nice part is that it's cheap to change it out an can be done with normal tools at home. Also, the IRM seems like it should be the only available option. I must be missing something. Who would want to drill a hole and make switching back to 9mm difficult if there was no downside to the IRM version? I think we'll find out more when the patent is finalized and we can really see how it works.

Congrats Richard
for the m11/a1 is it possible to use the IRM? i figure the gun is too small....or will you make the upper 2" longer to make it work?
As it is designed right now, no. I am working on a different IRM design for the M-11A1 and M-10.

extremely cool sir, thank you for all your efforts...
im hoping this leads to more uppers and idea's....maybe a 12 gauge upper?
Will I be able to use the dolos quick change barrel system?

I have the system , as it is it does not fit the receiver, I think it will only be a slight mod to make it work. It's one of the things I plan to test out when I get my unit back.
That system is designed to work with milspec uppers, but it doesn't fit any of my billet ar uppers.
I wonder if it would be possible to test out both at something like Knob Creek in October. I'm far enough down the list that I'd love a chance to try both before deciding. The hole isn't a deal breaker if there's an obvious advantage, but I'd rather not drill it if I don't have to.
