Thank you very much for the information. It was very helpful.
The 1000 series are based on the Norica Marvic and have the adjustable trigger. The Beeman 0035 has a direct sear trigger. I've ever heard of anyone installing a Marvic or 1000 trigger into a 0035. I seriously doubt it can be done as these are distinctly different guns. It would be cheaper just to buy a complete gun. The 0035 is what it is, an I expensive entry-level adult air rifle
I have a trigger group for a RS2 dual cal. laying here on my desk.Took awhile to find it. Bought the gun at a pawn shop for some Frankeinstien gun project. A subject for another time. Trigger looks just like the one pictured above. PM me an address and you can have it.The bent barrel is easy stuff. Bend it back. Find a handy tree fork. My neighbor has one right next to the fence. If it's bent at the barrel block, bend it at the barrel block. If the barrel is bent elsewhere look down the bore and you'll see it. Bend it there. If you bend it to far, bend it back. You ain't gonna' break it, it's bent anyway.
You can bend the barrel back down. Do some searches on it. As to the sear, that's a tough call. At least it is holding. I wouldn't mess with it since it could fail to hold should too much be taken off. Best to buy a new gun.On spring guns it is best to control the barrel or cocking arm (if under or side lever) at all times.
