After looking at all suggestions, I used #4x1/2" phillips head wood screws (4ea.) with the heads turned down to fit in the slot. It's solid as can be since most stress is on closing anyway. I think I will use this on all future 13xx type pump projects for a cleaner look. Now to finish sanding and shaping. Hope the cell phone picture shows them. Thanks all for ideas. Did some chrony tests with 14.3 g pells: 4 pumps- 455 fps, 6 pumps- 536fps, 8 pumps-602fps, 10 pumps- 654fps, 12 pumps- 679fps, 14 pumps-691, but not dumping all the air at 14. I guess I need a weaker valve spring for that. I will use only 8 pumps most of the time anyways. Is so easy to pump with the long pump arm.

Done with this one except for building up coats of Formby's Tung Oil. Old walnut soaks it up like a sponge. I will use a scope for a while, but will work on some iron sights some time down the road. Anyone know if the Disco rear sights are any good? I usually use Thompson Center sights but have to go to a lot of trouble making an adapter to the small 2260 barrel. I was lucky and got a great barrel from Crosman.

Consider peep sights.

I see where Williams WGRS-54 peep sight will fit on the back of the scope dovetail so I will try that first. I got a Discovery slide on tube base, so I can adapt some click adjustable iron sights to it as an option too. I usually use a brass post sight on a brake or TKO up front.

Thanks Mike, It is a Crosman 2200 tube and a 2260 trigger package and a brass Baker Air Gun trigger. Also has the two adjuster screws that come with the trigger installed. They adjust the let off point and over travel. I think it is a big improvement over the stock plastic trigger. I installed an adjustable rear sight on a Discovery slide on base as pictured here. I am ordering a Williams rim fire peep sight to try also.
