Umarex Octane Trigger Assembly
« on: November 23, 2013, 02:50:04 PM »
Several of us Octane users have removed the Octane action from the stock for various reasons only to learn the hard way that the Octane trigger assembly is held in place by several pins that will easily fall out if not very careful. I wound up with a pile of pins and parts with no clear understanding of how to put the trigger assembly back in place. A call to Umarex was a waste of time. I have tried putting things back together but about once in every 10 breaks of the barrel, the trigger and safety action locks up and the safety must be forced to the off position and the gun fires immediately. (Obviously very unsafe) I suspect the sear is not positioning correctly, but not sure why.  There doesn't seem to be a whole lot of information about the Octane just yet, too new I guess, but if anyone has any pictures or diagrams of the standard trigger assembly I would be forever grateful.

I BOUGHT A NEW WEBLEY PATRIOT (TURKISH) .25 FROM PA.....SHOT IT A COUPLE DAYS---AND THE SAFETY/TRIGGER (QUATTRO) WAS SO POORLY MADE AND FITTED, IT WOULD GO OFF AFTER THE THIRD OR FOURTH PULL.

SEND IT BACK!! IT IS UNSAFE

I had the same thing happen to me when I removed the action from the stock on one of my guns. I put it down on the bench, and by the time I got back to it there was a pile of pins and parts! It took me a while just sitting and looking at the parts to figure out how they went back together. One thing that helped me to figure it out was to use "Finishing" nails rather than the pins while I was puzzling out how to reassemble it. The nails would drop in and not fall through. Since the nails are very soft, I wouldn't leave them in place of the pins, but they were a great aid in reassembling the trigger. Not sure why they do it that way at the factory... I guess that it's just the cheapest way to do it.

I had a similar experience the first time I removed the stock from my Browning Leverage rifle - the trigger assembly pins fell out under their own weight.  Turns out that, by design, the pins are held in place by the interior walls of the stock.  Not a bad thing unless you lay the gun on its side when removing the stock like I did.  I'm betting that the Octane design also uses the interior walls of the stock to retain the trigger pins.  My solution: NEVER LAY THE RIFLE ON ITS SIDE WITH THE STOCK REMOVED.

Things are looking up for the Octane. After a bit of meditation in the shower and rethinking how the mechanism is supposed to work, I came to the conclusion that the sear spring was probably not doing it's job properly. I disassembled the trigger mechanism for the tenth time and spread the spring arms a bit. ( I think they probably got a little compressed with all the trial and error I experienced. Once everything was back together I went to the woods and put about a hundred rounds down range and the gun performed flawlessly.

Since I already had the scope off for the trigger maintenance, I mounted a Browning multi-reticle red dot which reduced the overall weight by about a pound. ( Don't sound like much but you can tell the difference) I had fun sighting in the red dot and the gun is still quite accurate out to about 40 yards. The red dot has a cross hair reticle with about a 1 mil center dot which makes it fine for what I do most with the gun which is hunting. A side effect of the red dot is that I can no longer take those 50-60 yard shots that I used to take, which were probably too far anyway. I won't keep the red dot on forever, but it is fun to do something different for a change.
