Make & Use 'Ranger Bands' (to include a Reflex II enhancement) Ranger Bands are strips of bicycle inner tube that can be used on the AR-15 for everything from securing flashlight tape switches and holding magazines to the front handguard, to improving the low light capability of the Reflex II sight.

Improve the Low Light Performance of your Reflex II The Reflex II is a great sight but has some problems when you use a strong light source (like a Surefire Light) at night against a light background (potential reticle washout). Also, some people hate having to adjust the polorizing filter as the light situation changes. This article presents a modification so you always have the clearest view through the lens for most lighting situations. However, when a 'washout' is possible you flip down a lens cap and the sight becomes an OEG (Occluded Eye Gunsight). This instant on/off system is quicker to use than the filter, but requires use of both eyes and binocular vision.

Improve the Attachment of the KillFlash filter for your ACOG The KillFlash filter is used to prevent reflection off of the lens of an optic (they make them for a variety of optics). The author has come up with an improved method of attaching the filter on an ACOG so you don't lose use of your iron sights. The method is cheap, effective, and quick/easy to do.
