I believe its a LOW owned design and they put Tract's name on it. Its almost identical to the Delta Stryker also manufactured by LOW.
Its a solid optic. I'm not personally fond of the narrow, tubular sight picture, the 41oz weight (30x Toric) or the gargantuan turrets, but it will perform per its price point.
I have their spotter and it is quite nice. A friend bought their 4.5-30 ELR scope and his comment was that he liked the glass as much as his ATACR, but the turrets were not quite as nice. I'm considering one for my new shorty 308/Impact.
