Nightforce FC-MRx (MOA)

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 40 MOA — the part of the reticle you aim with. This reticle carries marks out to 116 MOA; the rest sits beyond the edge of this drawing.

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

Subtensions

Official FC-MRx sheet, MOA column: A=0.75 centre dot; B=14 segmented circle (outer); C=64; D=4; E=16; F=7; G=0.21; H=4; I=2; J=4.8; K=3.4. Sheet text: the grid extends to 64 MOA. NOT a converted copy of the MRAD reticle - it is a different drawing with a 4 MOA grid, a wider circle gap (K=3.4 MOA where the MRAD is 0.5 MRAD, a real difference and not a units slip) and one dot size throughout. Grid is a christmas tree: +/-4 MOA at row 1 widening to +/-16 from row 4 down to 64.

How this one was checked

Rebuilt 15 Sep 2026 from the FC-MRx sheet (REV 1225), page 1, lower-right disc, at 1.5389/1.5433 pt per MOA. 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 (4 MOA pitch to +/-16) 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 to +/-32 MOA with minors every 4 MOA offset by 2, 0.74 long, majors 3.0, the 16 MOA mark 6.0 and the 32 MOA mark 10.0; elevation the same to 64 MOA, the last bar 6.0 wide. Circle outer diameter 14.01 against a published 14, ring 0.757 thick, top gap 3.43 (K=3.4) and side gap 4.82 (J=4.8). Bars taper from 34 MOA to full 7 MOA width at 64.9, and below centre from 66 to 96.9; the outer ends are the artwork's bound, not a published subtension. 116 grid dots over 16 rows. Mark positions are put on the published 2 MOA graduation rather than taken from the drawing; the largest correction that needed was 0.11 MOA.
