I have a Benjamin Air ******, Model 117. It won't hold air pressure and likely needs new o rings. Who can repair this?

Today Crosman owns Benjamin air guns. They offer a Free service to locate repair shops that repair airguns.

Yes! Get your rebuild kit here:

If a drop of oil in there won't swell up the seal, you will have to send it back to Crosman. They bought all Benjamin/ Sheridan services, they repair the rifles fairly cheap. You cannot take this apart, If you do, you will be sending them the pieces anyway. They have giant presses and jigs for holding the springs. I have had a bunch of rifles sent there. Check it out.

Crosman bought out benjamin / sheridan, and they still repair just all their pump guns. The ring sounds like a piece of a pellet, the barrels are silver soldered to the bottom tube, Not lead. Also, the repair kit should not have too many parts, you can only go so far with those guns before needing special equipment to get them apart. Get a hold of Crosman and tell them that benjamin sent you a bad part. They should fix it.
I had an old Benjamin Franklin in .22 cal, it was just a brass tube with a stock and barrel. I sent it to them, to be repaired, and I wanted the .22, because I had the 5mm and the 177. So I got it back, cost $29, New barrel, in .177, soldered on, new guts, new paint, trigger, bolt, the works.. Brand new gun. I told them I wanted the brass and I wanted the .22, They said oops, sorry. I didn't complain, nice old gun. Hope this helps.

Springs tend to loose their performance after a few years is air rifles. Check also the seal/o rings on the piston rod and the blow hole. I found waxing it with Vaseline makes it last longer and seals more.

I recently purchased a rebuild kit for my 342. I bought the kit from airgundepot. It was the kit for the
392 and I modified it a little. On the new plunger, you have to drill a hole in the center of it the same
size as the pin's smallest diameter. You can use all of the parts in this kit except for the small o-ring. I think it sold for about 39 dollars or so. My rifle was manufactured in 1972 and it fires like new.
