Does anyone make a gas ram or springer in the bull pup configuration?
-
Springer Bullpup. Yeah, I'm interested. Those would be custom guns. ;)
Here's a thread with a discussion of this:

I think it would need to be a side lever. ::)
-
Qb57 was a chinese springer pup.
-
I'm not an inventive person and I just can't invision a springer bull pup design.

Ray Apelles used a Diana54 bull pup to take 2nd place in the Worlds in New Zealand.

And here's the picture

Google QB57 air rifle. I have two. One is .22 with the barrel permanently attached with loc-tite and the other has both barrels .177&.22. A while back I was hitting wine bottle corks with the .22 at 25 yards.

It has been a while but I've seen pictures of the gun and somehow I thought it was co2. The QB name made me think that.

That baby would be a bear to cock. Were would the leverage come from?

I'm betting the cocking weight had been greatly reduced on that competition gun.

rays guns are set up at under 12 fpe as per competitions rules. I have had the pleasure to try a rws 52 in .12 fpe and it was a sweet cocker, not difficult at all. im sure with practice he had to have mastered how to cock that 54...
the qb57 had also a tactical companion, the qb6 i think. also take down, bullpupish kinda rig.
-
The Air Venturi TR5 is based on the Russian made IZH 60/61 by Baikal. The barrel is not in the bullpup position but the spring tube would qualify. Close enough?
-
QB6 is very different than the 57. No wood, stock folds underneath and rest against the bottom of the receiver. Mechanically it's similar to a B4-1 side lever bit the receiver is shorter.
-
Ive seen several russian springers made into bullpups. the two that come to mind were break barrels
-
You want to see one that's strange google QB89. Chinese bull pup, side lever springer. It compresses the spring backwards from back to front
-
El Gamo made one several decades ago. Sort of... El Gamo 68/68-XP. Pyramyd Air blog did a write up in 2012. Can't post outside links. Break barrel. Had a pistol grip just back of the hinge pivot. Several versions including a repeater model. NOT the Furia... fyi.

People on GTA are familiar with the El Gamo.
Also, above someone asked about leverage. I have an old Chinese B21. Made before the B30. Both clones of Diana 48/52. The side lever on my B21 has a telescoping extension. I don't know if a B30 has that. That recent M14 looking springer has a telescoping underlever cocking lever.

The TR5 is a bullpup. The 16" barrel is also too long for the gun, as it comes out of the box.
You could cut the barrel where the forestock ends, leaving 8" of barrel, and it wouldn't lose any velocity. If you also added a couple lbs of weight to the hollow spaces in the forestock, I am sure it would shoot more accurately like this, than with the stock barrel.
My TR5 barrel is shortened to 10", leaving only 2" of barrel sticking out the forestock. But I have 14" barrel shroud attached, for the weight. So that kinda defeats the purpose of a bullpup. It's extremely accurate in this setup.
It's more accurate after the barrel chop, even without the shroud. But it's an extremely hold-sensitive rifle, until you add some weight to it. The optics rail is not satisfactory, though, IMO. I modified mine with an aluminum picatinny rail.

Not really a Bull pup but pretty close.

If you want to see factory built bull pup springers do a google search. Qb 57, B9-1, B6Z and QB89. The 57 and 89 were made by Industry Brand the other two by someone else like Peak, BAM or XS. I got a couple 57's and a B6Z. I have a QB89 in parts.
