Good evening folks, sorry for not checking in sooner. We're the ones who make this.
We are indeed going to tighten up the fit on the adapter this time with the way the Bren rear head was changed slightly. The newer versions of the Bren rifle with the changeable rear head (which is what this fits) are what we are fitting these for.
We have 4 people firmly committed. We need 6 more to make the run. It will be a limited run, probably only 20-30 due to cost and the length of time we like to keep things on the shelf instead of the 50 we made last time.
Ours are an improvement on the MAA adapters in several ways, specifically the machining is done in much smaller steps so that you get a smooth finished product and not the machining lines you see on the MAA. Our anodizing is also better, a deeper charcoal rather than the slightly purple hue. It's never 100% black, but it's much closer.
The only "down-side" is that you have to use the rear head. We did that deliberately so people could go back and forth at will.
We do not currently have plan to develop a pic rail rear adapter but it's always possible. We did one for the Sig556 but never brought it to market because we think the ACR stock is much better. We'd need 20 people for that, as we have to cover the cost of CAD programming and prototyping in the initial run.
For those interested, come and check out our new website (which people have been asking for). Long time coming, finally getting it up and running. There's a way to contact us there or you can join us on the FB page.
Thanks!
