I'm sure that happens to a lot of you out there when you have a good gun, but you always want better. So, those of us with money buy new ones, those that are without or with little money mod theirs. So, I decided to convert my gun into a bullpup. I think it was a good idea because the gun was front heavy due to 29" stainless steel tube, but now it is perfectly balanced. The stock and scoperail is taken from Chinese sidelever.
My B9 shoots RWS Meisters (7.0gr) at 490 quite consistently. I've put about 1000 rounds through it now, and though I 'tighten' the locking ring every once and a while it's never really been necessary as it has never been loose.
Perhaps yours is faultly.
I have two friends who have the same gun and are happy with them...I'd hate to see a good gun get a bad rap because of what could perhaps be one faulty unit that gets posted on a widely read forum.
I looked at the QB-57 as well. But in truth I wanted one gun that looked 'contemporary military' and the synthetic furniture of the B9 was more in keeping with current bullpup assault rifles.
So far I've been very pleased. At 1/3 less money than my Slavia and 2/3 less than my Avanti 853c I'd rate the overall build quality as very good. Maybe not quite as fine as the above, but well worth the price.
I've installed a Vortex Red Dot and it is darned accurate out to 30 yards (though of course not much hitting power).
I bought it after a bad experiece with a Crosman Nightstalker (they ALL develop seal leaks and when those big .88g cylinders loose all their contents when you screw them in it's real annoying). The B9 has worked flawlessly and has completely changed my opinion of Chinese guns.
It is a Crosman trigger shoe from my crosman carbine...

I cut regular QB trigger unit shorter to fit the stock, then hooked one of the holes on the QB trigger with hanger wire. Then, I installed 2 crosman 22XX barrel bands upside down and passed the wire thru them. I connected a brass rod to a crosman barrel and put the barrel thru the barrel bands on top of the hangerwire. That helps the trigger to be pushed evenly without wobbling much.
In all the years I've been part of this forum I have never commented on any bullpup. I've always liked the Idea but not necessarily the actual translation. Your gun however looks great, well thought out, and very appealing in apperance. I think you have done a great job and I'm glad you took the time to show us your work. Your gun deserves to be enjoyed.
