Looks like a Swiss Arms TG-1. They've been popping up at my local Wally World lately, but I'm a little leery. Too much plastic for my taste. They claim 1400 FPS in .177, but I haven't seen any actual chrony testing
Its hard to say from that small photo but I'm thinking a Gamo of some sort based on the safety in the trigger guard. (Looks just like a Marauder trigger/safety). Anyway that's a clue I noticed. Was scanning through photos of guns on Pyramids site looking for ones with a safety like that and the Gamo's stand out.
I think Biohazzard has ID'ed the gun. Swiss Arms TG-1. I found a couple other pictures online that look like a perfect match. The owner won't respond though. I like the idea of putting a cheap break barrel in my collection, but I don't want to spend a fortune on it.
I have that gun. It's pretty good. It is hard to cock though. The gun is better than the scope. No parallax adjustment. I had the Strelok app on my phone and was getting 960-970 fps with it.
