Tenebraex Flip Covers(For ELCAN) provide protection for your optic and can conveniently flip up and out of the way when it’s time to shoot. These Tenebraex Flip Covers for the ELCAN SpecterOS, SpecterDR (DFOV14 & DFOV156), and TFOV139 Sights are a great way to protect your expensive lenses from dirt, debris, and scratches.

The 2-Tab Ocular Flip Cover can be attached directly to the Eyepiece end of the DFOV14 & DFOV156 (This Flip Cover is interchangeable with either sight) without any additional parts, however in order to attach the 2-Tab Flip Cover to the Objective End, you will need either an Attachment Ring (PN: SDR-AR4-AR) or a Killflash (ARD) with a knurled (or profiled) edge (PN: ARD-SDR-B for Black or ARD-SDR-T for Tan).

The Anti-Reflection Device (ARD), also known as a Killflash can be purchased separately, however Weaponsights.com includes the ARD (except the TR139) and Flip Covers with every sight purchased. Please note, the TR139 does not have an available ARD (KillFlash) and the Flip Covers simply attach to this optic.

If your SpecterDR or SpecterOS has the older style Anti-Reflection Device (KillFlash) with a smooth edge; you’ll need to use an Adapter Ring to attach the Objective Flip Cover or upgrade to the newer ARD with a knurled edge. For those of you with the smooth edge ARD’s, because of a change in the Flip Cover design, you’ll also need to ensure that your Flip-Covers have 1 single Tab…not 2. The single Tab design will work with the Adapter Rings.

The new 2-Tab Flip-Cover design eliminates the Adapter Ring, which had a tendency to crack when over-tightened, which was very easy to do with a metal screw and plastic ring.

Again…

In order to attach the Objective Flip Cover, you have to have either

1. The Old Style (Smooth) ARD + Adapter Ring + 1 Tab Flip Cover
2. The New Style (Profiled Edge) ARD + 2 tab Flip Cover
3. An Attachment Ring + 2 Tab Flip Cover

This Attachment Ring works in place of the ARD. If the ARD is installed, unthread & remove the ARD by turning it counter-clockwise, then install the Attachment Ring by threading it clockwise into the objective end. The Attachment Ring has a profiled edge, similar to the ARD and allows you to install a 2 Tab Flip Cover.

The Attachment Ring Part Number for the SFOV4 and DFOV14 sights is SDR-AR4-AR.

The Attachment Ring Part Number for the DFOV156 sight is SDR-AR6-AR

One more time…you must have the ARD or Attachment Ring installed in order to use the 2 Tab Objective Flip Cover.

New design (2 Tab) Ocular (Eyepiece) Flip Coves no longer require the Adapter Ring and the same Flip Cover will fit both the 1X-4X & 1.5X-6X Models.

If you have the older style single tab Flip Cover (PN: UAC013-FCR), you will need the Adapter Ring as well.

KillFlash ® ARDs use a high-tech honeycomb material to provide a low-cost, retro-fittable, field-practical way to hide reflections from optical surfaces.

OPTIC INSTALLATION:
Simply screw into front of scope. Do NOT use any thread lock compounds.Carefully thread into the objective (front) of the optic. There is a risk of cross threading on finer threads. The ARD should screw in without any resisitance. Once the ARD is fully threaded and finger tight, continue to hand tight. Do not use thread sealants or tape. To remove, turn counter clockwise.

OPTIC CLEANING
Treat the honeycomb grid with the same care you would any fine optical surface. If clogged with dirt or grit, remove ARD from optic and blow clean.
If necessary, run palin water through the honeycomb to clear it. Tap the killFLASH^® housing lightly on a surface to clear excess water, then blow through it to remove the remainder and dry it. Reinstall ARD.

Adapter Rings
