The only Geco rifles I've seen have been inexpensive old German Boys rifles. I see them at shows occasionaly, but I'm not sure what models I've seen. Does that somewhat describe what you have?
This rifle is somewhat unusall. It's got a large diameter bull barrel with Military stlye leaf sights similar to a military training rifle. the trigger is fair and the action has a cheap looking bolt on it. It is not drilled for scope mounts.
the stock is a very plain, low quality walnut. Overal barrel length is 26 1/4 inch.
Lenght of pull is about 14 inches. I don't think that it's a boys or youth rifle.
Ron had one for a little while and sold it. Guns America had one selling for 600, picked this up for 300, it was nice looking, and shot well. We used it for the turkey shoots at 27 yrds. It reminded me of the Brno in some ways.
