Primary Arms GLx 2.5-10 Shockcord Scope Caps and Killflash

There are two groups of files for this. One is just the front and rear caps. The other is the front cap with a kill flash.

Shockcord Cap with Killflash:

I have ‘remixed’ and added to this kit by creating an optional front killflash/anti reflection device. The cap and retaining ring can be printed with any nozzle size you prefer but the ARD should be printed with a 0.2mm nozzle or 0.4mm nozzle depending on the file you choose. The walls for the hexagonal grid are 0.2mm wide/0.4mm wide.

The Retaining Ring is a slip fit by design. If it prints correctly it should have a 51.7mm inner diameter. I print it with the “ears” down and use the “experimental” setting of “make overhang printable” as there is a “stop” at the end of the ring for the ARD. This is my own design I made using Google Sketchup. I would suggest you print this as is and test fit it. You may find you need to scale up or down .25% on the X and Y axis to add or remove a 0.1mm to/from the diameter. This will adjust the amount of friction.

The ARD should print to have a 51.375mm outer diameter. It should easily slide down inside the retaining ring and nest against the “stop”. It can be retained held in place with friction only as the scope will keep it in place but I added a bit of E-7000 glue anyway. This ARD was just sized from this customizable file on Thingaverse (https://www.thingiverse.com/thing:4875497)

The scope cap is sized to fit over the retaining ring.

Materials needed:

Directions: 
- Tie a knot at the end of a length of shock cord.
- Feed the cord through one of the holes in the cap, then through a matching hole in the ring.
- Feed the cord through the opposite ring hole and through the back of the last cap hole.
- Leave a small amount of slack and tie a knot in the cord near the face of the cap.
- Mount the ring onto your scope or light and flip the cap over the lens.
- If there is too much slack in the cord either slide the ring further back or pull one end of the cord tighter and tie a new knot.
- Cut off excess cordage.

Tip: If none of the rings fit your setup and are unable to use the source file to make your own you can negate the use of the ring by looping the cord around the scope/light mount.
