Welp, still haven't bought the steiner. *also a fair warning, severe gun autism post incoming*
NX8 went back on my grendel build, so I had a Trijicon 1-8 on the gun as a placeholder and strongly disliked it. Why?
Well, the gun without a scope and suppressor weighs all of ~4 lbs and 14 oz.

The Trijicon 1-8 and mount? That weighs 2 lbs, 1 oz.

So with the Trijicon 1-8 and the CGS Hyperion suppressor, my lightweight, handy rifle is now 7 lbs, 14 oz.

So I started experimenting with other options. Using an AGM Rattler thermal, I dropped the weight down to an even 7 lbs. But I need to swap over to the cantilever mount on the thermal for better eye relief...and I really prefer using that thermal as a clip on in front of day scopes on other guns so I don't really want to change mounts.

I didn't want to spend ACOG money, but I was happy to spend Primary Arms level money to try out the micro prism concept discussed earlier in this thread. It wildly violates the "spend as much on the optic as you do on the gun" rule, but the PA 3x micro prism with the 300blk reticle weighs 1/4 of what the Trijicon 1-8 did.
As pictured the gun weighs 6lbs 4 oz. Much, much more in line with the concept of the rifle. It drops to an even 6 if I swap out the full size Hyperion for the K version of the can.

I have an ADM mount coming for it tomorrow, and I have a couple other ideas to try if that mount doesn't work. Eye relief with the PA stock mount works, but its almost too far forward. Hopefully either the ADM mount or directly mounting the micro to a unity riser mounted backwards gives me better eye relief, but I think this is much closer to what I would like to use with this gun. Now I just need to test how well the reticle lines up with the drop of my preferred 300blk loads.
One more picture comparing size to a G19 to demonstrate why I hate turning something that started out weighing less than 5 lbs into another 8-9lbs rifle like all the rest of my guns: the mini fix should be light and small. There's literally no point to the thing if it isn't as small and light as possible.
