Nightforce FC-MRx

Drawn to scale from Nightforce’s own specification sheet, and checked mark by mark by a person. This is the same geometry Harson Ballistics draws your holdover on.

Framed to about 12 MRAD — the part of the reticle you aim with. This reticle carries marks out to 30 MRAD; the rest sits beyond the edge of this drawing.

Drawn from Nightforce Optics, Inc.’s published specification.

Subtensions

Official FC-MRx sheet, MRAD column: A=0.2 centre dot; B=4.25 segmented circle (outer); C=20; D=1; E=5; F=2; G=0.06; H=1; I=0.5; J=1.2; K=0.5. Sheet text: 1 MRAD aiming grid extends to 20 MRAD. The grid is a christmas tree, not a rectangle: +/-1 at row 1, widening a column a row to +/-5 from row 5 down to 20. Even rows carry a 0.2 MRAD dot and odd rows from row 3 a 0.146 MRAD one, so 2 MRAD steps can be counted; rows 1 and 2 are both drawn fat. The sheet draws the crosshair, circle and centre dot in red and the grid dots and bars in black - taken as which parts illuminate, and recorded per element.

How this one was checked

Rebuilt 15 Sep 2026 from the FC-MRx sheet (REV 1225), page 1, upper-left disc, at 5.5934 pt/mrad. Page 1 of the sheet is to-scale VECTOR artwork, so this was read from the drawing operators rather than measured off a raster: every mark comes back as an exact rectangle, which is what catches a mark that is in the right place and the wrong length. Scale was fitted to the aiming grid (1 MRAD pitch to +/-5) with the optical centre taken from the centre dot itself. Page 2 is a raster and is stamped "Reticles not to scale" - do not measure it; it is useful only for reading which feature each dimension letter points at. All eleven published letters were walked and each one lands on a measured feature: A the centre dot, B the OUTER diameter of the segmented circle, C the windage scale, D the grid pitch, E its half width, F the heavy bar thickness, G the line weight, H and I the major and minor tick SPACING (not their length), and J and K the side and top gaps in the circle, which are chords measured at the outer radius. MEASURED: windage runs to +/-10 with minors every 0.5 at 0.2 long, whole-mil marks 1.0 long except the 1 and 2 mil marks, shortened to 0.4 to clear the circle, 5 at 2.0 and 10 at 3.0; elevation identical in the other direction, whole mils 1.0 wide and halves 0.2, to 20 mil. Circle outer diameter 4.249 against a published 4.25, ring 0.249 thick, cut by a 0.500 gap at 12 o'clock (K=0.5) and a 1.228 gap where the windage line crosses (J=1.2). Bars taper from a point at 11 mil to full 2 mil width at 20, and below centre from 21 to 30; their outer ends are the artwork's own bound (the sheet draws them past its field-of-view circle at 28.2 mrad), not a published subtension. 180 grid dots over 20 rows. Mark positions are put on the published 0.5 MRAD graduation rather than taken from the drawing; the largest correction that needed was 0.03 MRAD.
