While I agree, if it's reliable, no one cares how ugly it is. We don't have these in the wild yet to know how reliable they are. Let's remember, every new optic is "1000x more reliable than Z-optic" as part of the marketing regime, but 1000x more reliable than a DPP is still zero.
Lest I be accused of doubting our SMEs with hands-on experience, I am not, it looks like Aimpoint may have a winner here. Unfortunately, that's a single digit sample size of optics. We have at least one guy here who have double-digit sample sizes of just broken Deltapoint Pros, and counting the others we have close to two dozen busted DPPs reported right here on P-F over the last 3-years, and half again as many busted RMRs, plus all the busted other pistol optics.
In other words, I'm not ready to proclaim any pistol optic reliable, closed emitter or not, until it's out in the wild to be beaten on severely.
As for the Acro P-1, it really is as ugly as an inside-out asshole. That thing hit every branch on the ugly tree on its way down and then someone beat it with an ugly stick for good measure. The blockiness of the optic is going to cause concealment issues for many, I guarantee it. A rounded T1-type tube of a smaller diameter would have worked much better. I know it's harder to make round glass than even curved glass, but I can think of a dozen ways to improve the profile of this optic, but alas, not to improve it now that it's made. Honestly, just making the thing physically smaller would have merit. I know that would make the window smaller, not as good for gaming, but it would be way better for concealment.
