Research notes

Audit 2026-10-14: Exact UK page gives approx. 92 mm length, now filled, three LR44/AG13 cells and four selectable reticles. Its approx. 143 g conflicts with the distributor and exact THO-10-009053 listings at 220 g. Existing 220 g is retained as distributor-specific pending a variant/measurement check. Objective field 40 mm was not assigned as a measured rectangular window. Additional exact source: https://en.specshop.pl/product-eng-43095-Theta-Optics-Red-Dot-Sight-for-ASG-Open-II-Black-THO-10-009053.html Scope: technical specifications and source suitability; prices and market status were not re-verified. Numeric 0 retains the original import convention for unknown or inapplicable values. Blank batteries on unpowered optics are intentional.
