Customized .22 Caliber QB78 Deluxe Air Rifle
with Scope, Bullpup Conversion Kit, and More
The gun being sold here is a custom built and tuned QB78, produced by Stephen Archer
of Archer Airguns. For those unfamiliar with this CO2 powered air rifle, the Industry
QB78 Deluxe is a beautiful, all wood and metal Chinese rifle that looks a lot more
expensive that it really is. Shooting it is an absolute pleasure as it does not have any
recoil whatsoever. It is also very, very accurate. This rifle operates with two CO2
cartridges placed back to back in a tube located beneath the barrel. The barrel is
rifled and has dovetail grooves for mounting a scope. The trigger has three
adjustment screws so a user should be able to set it just the way he or she likes.
To recreate this package would cost you well north of $500. I am asking only
$365 plus $35 shipping.
The options on this particular gun are listed below. This gun chronographs at 609 fps
with JSB Exact RS pellets. Spare O-rings for the CO2 capsule tube piercing cap/cover are

With this gun comes an NcSTARŪ 2 - 7x32 mm AO Pistol Scope with two different kinds
of mounting rings. This scope was selected specifically for this gun because its
long eye-relief is needed on the bullpup conversion, but it works just as well on
the stock gun. Blue-coated lenses and a 32-millimeter objective provide
distortion-free clarity, while variable power magnification and a long eye relief
for extended mounting capability make it a versatile shooting accessory.
Also includes lens caps.

Two different mounting systems are included in this sale. The first is a pair of 1"
scope rings for the stock QB78 dovetail. The second is a pair of 1" mounts fitting
the Picatinny rail of the bullpup.
The case is a Plano "Gun Guard" hard shell case, which retails at 29.95.
Included with this gun is a bullpup conversion kit. The kit has a polymer body with internal
steel reinforcement and integrated Picatinny top rail for mounting a scope (or laser or
flashlight, etc.). Please be aware that this is not a commercial product and is not in
working condition. It is a hand-crafted demonstration prototype constructed from off-the-
shelf components. While cosmetically complete, it does not have a fully-developed trigger
linkage. The sunk cost is certainly over $150, although detailed records are not available.
Complete instructions for assembling the bullpup are included with the kit.
Shipping to US only.
If you want the gun quickly, paypal is fine with me. I'll pay the paypal fees.
I'll also take a personal check, but there will be a two-week delay until it clears.
