The Ultra Light Weight Diopter Assembly (PVS-14 Style) is a unique product designed by OPFOR in Canada, and produced in the U.S. via HP Multi Jet Fusion additive manufacturing.
Warning: Do not try to disassemble and bend the retention flanges! They may break!
Note: Does not include eyepiece, this is the diopter only.
It is the absolute lightest PVS-14 eyepiece diopter assembly on the market, weighing in at 7-7.7 grams (depending on pattern), compared to the 19.3 grams for a Mil-Spec assembly. That's a weight reduction of over 60%.
In a binocular system these alone will reduce system weight by roughly 4-5%.
The design is optimized for 3D design, hence the name. It makes use of complex geometries that would be extremely difficult to machine, but are printed very efficiently. In doing so, the design was able to eliminate extra unnecessary components such as the diopter cell retaining ring, diopter wave spring, and eyepiece locking ring.
Instead of a locking ring, the eyepiece uses two flat tipped set screws that will not damage the threads but still allows a solid lock.
These should be compatible with most standard PVS-14 eyepieces and most standard housings.
Confirmed to work with:
- Eyepiece Cells: RPO, Qioptiq, Fujinon, OE
- Housings: AB RNVG, AB Mod3, AI Sentinel BNVD-1431 and BNVD-1431 Mk.II, Nocturn Industries Katana, ACT DTNVG, LLI Aeternus, PVS-14, Vyper-14, Hyper-14

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard
White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it.
Orange is easy to see in the grass at day
They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too
The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.

Great for aggressive chewers - Great for clean teeth
I never thought these would stand up to my 60lb pittie puppy's chewing. But they are far and away her favorite toy and are holding up beautifully. One squeaker insert bit the dust -- which is not bad since it gives us one silent one. But otherwise they are holding up superbly to her powerful jaws. We have tried a lot of toys. So far, all the "for aggressive chewers" toys have been torn apart within days if we are lucky -- usually it's minutes. But these balls show little-to-no sign of wear. The squeakers are very loud which she loves can get a bit tiresome. So, as I mentioned, having one silent one is a great option. And she really likes the texture. She loves them so much, we bought a second set and will probably buy a third to have in reserve. (We are realistic and don't expect them to last forever.) All I have to say is "where's spiky ball" and she instantly stops what she is doing and goes on the hunt. A great buy!! (NOTE: It's been almost three months and one is just beginning to show some damage. Given that she plays with them non-stop, they've showed amazing durability. And everyone comments on how clean and beautiful her teeth are. I don't brush them or give her dental treats. So it has to be these balls!!)

Good sturdy ball for aggressive chewer
Size: 4.5"
Nice heavy duty ball that my 7 yr old pitbull can chew on and not destroy it in 2 minutes. Wish that could get 3 for the cost but whatever. Nice bright colors . Good size that he won't choke on it .
