It was announced some time ago. My record of it was saved on November 12. I wanted to use it on Kel-Tec SU-16, where AR optics often cause "jaw weld". It was even promised to have a direct interface to the Picatiny rail, in some versions at least, which is more than can be said about RMR or DPP. My biggest concerns about Acro P1 are the cost and the simple pistol reticle. Currently I have TRS-25 on there that I bought for $80. That's a far cry to $550 street on P1.
