Delta Tactical - Stryker 4.5-30 x 56 HD FFP

Rifle Scope Military standard Engineers Instrument Report*

BLUF:
The Delta Stryker 4.5-30x56 FFP performed perfectly on tracking tests conducted using in-service military testing equipment. In addition, no lash was recorded in the windage or elevation turrets, and no reticle can’t was detected.

Aim:
Level scope reticle and conduct vertical and horizontal tracking tests to assess mechanical accuracy and reliability.

Method:
After being mounted in a serialised pair of Vortex Precision Matched rings, the scope and rings were mounted onto a picatinny fixture built into a levelled TTS bench. The levelled collimator was then placed in-line with the scope, and the scope was then levelled against the perfect reference of the collimator. Horizontal tracking tests were conducted twice, out to five milliradians each side. Vertical tracking was then twice assessed from zero up to 18.7 milliradians (downward travel was not evaluated, as zerostop was fitted). Both windage and elevation turrets were then evaluated for backlash by repeatedly dialling corrections and comparing dialled values to observed values.

Results:
No reticle cant was detected. Horizontal and vertical tracking tests showed nil deviation through the ranges tested.
(COMMENT: The EIR Tech remarked that this was the first time that they had observed perfect tracking results over such a large testing range). No lash was measured in either windage or elevation values for the values tested.
