Scot Laughlin's Custom All Weather 2260

2260 with short crosman receiver atop a mini riser made from aluminum tube. Barrel is a 2200 soda straw
tensioned inside a titanium golf club shaft. Three screw mod to the trigger, bulk co2, SSP 250 rear cocking
striker assembly. Factory stock, reshaped, bedliner finish and stick on cheek piece. The idea was a weather
resistant light hunter for rainy days.
I've got a Cothran stainless receiver and gas tube waiting for me to get back to this one.

We got the gun last week and soon found that it was great fun to shoot but peppered the target like a shotgun.

So after a major CO2 leaking problem it was in bits, whilst I was in there I thought I would tinker. Here's the current mods, mostly to improve accuracy.

The black spring-loaded assembly (the 'detent body') at the front of the valve drilled out to 4mm, installed an O-ring into the obvious slot on the outside rim the plunger, makeing sure the O-ring didn't bog the plunger- but sealed it somewhat. I need to fit a stronger spring in here also but didn't have anything handy. I'll get that next time.

Stablized the pea tube barrel with polystyrene inside the shroud

Lubed and greased up the trigger

Re-crowned the barrel

Lubed the barrel with Dryslide

A few more bits and pieces to go, but its now shooting tight half inch groups, 632ft per sec at 9 degrees C. 48 shots to a bulb.
