Something happened to my 48? **Update**

Mine shot good since new. When the spring broke at about 10,000 shots I put the vortek pg2 kit in it and the kit made the shot cycle very quick and more accurate out a longer ranges due to the smoother shot cycle. I normally shoot mine out to 80 and 100 yards and it is very accurate. Think you will really like that kit. Word of advice though, use the blue factory piston seal instead of the one that comes with the kit. Had some fps variations with the moly seal in a couple of guns. Now I use factory blue seals in my Diana’s and ARH seals in the others. Just my experiences and hope it helps you. 
 
"1BadDart"I installed a PG2 kit in my 34 and it is like a different rifle, well worth the costs IMO. I was planning on doing the same with the 48 but at this point I'm not so sure that I wont just fix it and put it up for sale.
Thanks for the info Butch.
It is really hard to get pi$$ed at companies (I have been a bit naughty but as you already used that I guess it is ok...I will be a good boy I promice) I know from my 2 month long maximus ordeal....but that is a different duck.

This the thing broke.....I generally go under the rule that if it is made by man it can be screwed up.....unless this is a common thing (looks like two have had it on this forum alone) there is not a real cause to toss the baby out with the bath water.

You do scare me however......my new 48 should be on the truck to be delivered today. Midway had them on sale last week....$100 cheaper then Pyrmaid.....I had to do it. Wanted a 54 but that was out of stock.

I had a 54 years ago but sold it when my left side had issues....so I figure I will be shooting this big girl off a rest....no issue with that.....not sure how the cocking is going to be now....trying to get stronger again so I can play more.
 
My 48 shoots well and I like the rifle, that being said if I had bought the 34 first I probably wouldn't have bought the 48. I was chapped when I started this thread and still am to a point. I understand things breaking and wearing out and if this rifle was bought used or several years old, ok. But IMO this being a pretty new rifle the stem shouldn't have pulled out of the piston.

A couple weeks ago I commented to a buddy that I thought the spring was broke because it was vibrating after the shot, something it had never done. Unlike the 34 the 48's shot cycle had always been smooth and vibration free. Looking back the rifle was telling me something and I didn't listen.
 
Well it's together and it cocks and fires................ but it only fires when you turn it upside down and give the sear a little nudge with a screwdriver. I tried adjusting the trigger and it makes no difference.

I hope I can communicate this so it makes some sense. When it cocks it sets the trigger like it should, push the safety off and squeeze the trigger to the second stage, the squeeze to fire. it makes a small click and the trigger comes back like it should. The piston is still cocked at this point, pull the cocking lever back and at the end of the stroke I can feel and hear it click, at this point I can press the anti bear trap button and return the lever forward and uncock the rifle. However, when if I continue to pull the cocking lever back as just described it will click again and reset the trigger but will not fire unless I give the sear a little nudge with a screwdriver. I loosened the action screws too, no help.

With the rifle uncocked I can reset the trigger with a screwdriver and it works like it should. Also it won't bump fire even when holding the trigger back.

I'll take it apart and hopefully figure out what's wrong, just not today. I think I'll take my 34 out and relieve some stress. BTW I got my first kill with the 34 this AM, a sparrow on one of my bluebird boxes at about 25 yards, so today hasn't been a total bummer. lol
 
I did notice when I was assembling the gun that the end of the new stem is machined different than the original.
