Title: Bull pup break action plans?
Post by: Subway on April 26, 2016, 11:40:28 PM
Bull pups seem to be pretty popular lately and I was wondering if any one has made one at home out of abreak action? I have seen one called the Goliath 88 but can't seem to find plans to do it at home.

The Goliath 88 was made by Gamo I believe. You can google side lever bull pups made from Diana sice levers.

This Diana 48 is a beauty.

The Goliath is actually a Hatsan/Norica gun. Not currently available in the US, but here it is in Spain.

I have a QB57, and I've always thought that the QB89 would be a neat gun to have.

Has anyone on here tried to convert at standard break action Springer to a bull pup? Just looking for ideas on what I need to do with mine

I don't know about standard break barrel. I'd pick up a used D48 for $250 and use that. With a standard break barrel, I'd be worried about cocking the gun in a bullpup stock. Since the end of the receiver is at the but of the stock you have less leverage when cocking.

I thought about that but I think if I incorporate a handle on the rear area. Or simply prop the butt on my thigh.... lol ...
It ought do ok. I've removed the rear sights and found that there are 3 holes that I can use to mount the scope directly to the barrel with a scope rail. The only issue I see is the scope clearing the stock when cocking if it's mounted to the barrel

I thought about it. I have a few bull pups, all side levers. 2 QB57, 2 QB89's and a B6Z. Looking at the Goliiath88 it seems to me you need a break barrel with a cocking linkage from the barrel to the piston that's two piece so it goes straigt back and not down any. Then some extra thickness in the bottom of the stock for a rod of some kind to go from the new trigger back thru the stock to the old trigger and/or sear. You can google some bullpup stocks for .22 power burners and the Russian Nagant that might give you some ideas.

The cocking lever needs to clear the linkage to the new trigger position. The cocking slot in the stock might also interfere with the trigger.
