Has anyone found a tritium source?

PUMPED for this project, thanks OP!

Bought one from here: http://www.cpfmarketplace.com/mp/forumdisplay.php?108-WTS-Other-Personal, hopefully I'll get it in a few days.

I'm thinking hard about purchasing one of these.

As I mull over it, a thought: If one were to scrounge around for a small(1/2" dia or so) clear rod of plastic, solid or hollow, and wrap the fiber optic around it multiple times, you'd have an obscenely bright and compact light gathering source. Matter of fact, I'm going to dig through my parts bins right now for something of that description.

Ah, another thought! If you were to do the above, then add aluminum foil on the lower half of the coil(the part not facing upward for gathering light)...I bet it would be insanely efficient. Hit the outer layer of foil with some flat black so it didn't show...


Hmm...

It may actually be too bright.

My 18" of fiber optic in a coil is too bright in direct sun. I have to cover part of it with electrical tape.

I'm considering bundling a bunch of 1mm strands together on one end and attaching that to the light input on the sight, then arranging the other ends flat on the surface in front of the sight.

As this crude illustration shows.

Which mount will I need for the optic to clear the A2 FSB?

Thanks

Have you thought about taking a clear acrylic tube, inserting the fibers, then filling it with clear epoxy? It would bond them (and the tube) into one giant strand.

Yep, I plan to use a short piece of clear tubing to bundle the strands on the one end. The rest of the length will be bare and spread out to gather as much light using the shortest length possible.

I'm thing of doing the same on the top, a short piece of clear tubing with a bunch of 1/2 in to 3/4 in 3mm strands inside to gather light and channel it toward the glass.

Just ordered one. I have some 40 tubes from a broken bow sight. I'll post results once it's up and running.

Bonzer idea OP.

I'm glad to see pics of other sights being posted. I'm curious to see how other members were able to manage their fiber optics. Does anyone know of a better adhesive or epoxy to use? Anything that cures or dries clear and without a mess?

Guys, I'm reading conflicting reports here. How large is the hole in the front for the fiber optic rod that everyone is trying to find? Is it 1 mm or 3mm? Ihavnt received my sight yet, but I'm already starting to look for a fiber light source.

Also, how deep is this hole (insertable length)?

Not so much a hole, as a window for light entry. Front should work best with 1mm / 0.040 rod in color of your choice.

See the pictures of the front of the sight on page 3? There's the large window up top, then what looks like a small tiny round mirror below it? The small tiny "mirror" is the reflective doughnut you see. The small space between the two is where you need to place your fiber. Would be nice if there was a hole to put it in, but there isn't - you just put it in front of the window.

Ok, bare in mind I've not seen one in person yet, but what about taking a small tritium rod and puttying it against that circle? You would actually be blocking the sunlight from entering, but you would have a constant light source pressed uP against it. Then the putty would be painted black on the outside to try and blend it in with the rest of the unit. ???? Thoughts????

I was actually going to get a green tritium disc from over on candelpowerforums.com and try just that.

Based on what I can see with my Tritium gun sights, I don't think the Tritium is going to be bright enough in daylight to really do anything. I had an old Glock tritium front sight laying around that I tried to put up against the glass to see what would happen ––- nothing.

I put a flashlight up to the top hole to see what would happen (the hole on top of the sight). Lit up the night tiime "T" reticle real well, but there was so much light reflecting around inside the glass that you couldn't actually see through it any more - all you saw was the reticle.

I think the fiber is still the way to go. Also, the little shelf in front of the light window on the front is made of delrin or something similar - it does not take many adhesives well. Super glue worked best for me, but you need to take care to keep it away from the fibers as the super glue will corrupt the plastic in the fiber. In essence, I super glued the double sided mounting tape to the shelf, then put the fiber on the mounting tape, then epoxied the fiber to the mounting tape.

KF

k80 has a good description of what is going on with the sight. The 1mm fiber is fine. I got a variety pack of fibers, and went with the 3mm . What ever works is good, when messing around with these things. Everyone has their own thoughts on how to set it up. Here's mine....







First shots were off the paper, high at 25 yards. Probably 6 - 8 feet high at 100yards. Windage was almost dead on. Fired around 100 rounds as far out as 300 yards.

I'll say it again, cool little sight.

Thanks OP for posting about it.

Thanks OP for posting about it.



You're welcome. It's been fun watching the thread.

I took my M&P 15-22 to the range this morning. I shot a 5 round, 1.5" to 1.6" group at 50 yards with the little reflex sight. The ammo was CCI .22LR 40gr Standard Velocity. I did not think that group was too shabby for no magnification and a doughnut shaped reticle that is 2.5x to 3x times bigger than the circle I was shooting at. I quit shooting paper after that and started shooting 1/5th scale pig swingers at 50. Below is my target and rifle again.
