Good Points: Good power and accuracy, good finish-wood and metal, ease of disassembly/assembly, pleasing to shoot.

Bad Points: Internal metallurgy could use improvement- spring and spring guide.

General comments: The Xisco B-40 competes with my TX200 proportionately to price. The insides are a little less robust, yielding about 14.5 ft-lb. energy compared to 15.5-16 for the TX. I like trying for 1.25 inch circles at 50 yards. At right around 900 fps with 8 grains, the ballistics put this one ahead of 13+ fpe class guns like the CFX and HW77 (both fine guns) and make it just feasible for the 50 yard experience. My specimen was made after the barrel and breech were opened further (early models were reported to have tight breech and barrel) and likes a little larger pellets like the Crossman Premiers, both light (short) and heavy (long). Of course, the 10.5 gr. heavy takes the ballistics down to 800 fps or less. I run "contests" with a small battery of what I consider good rifles (TX200HC, HW77, RWS 48, CFX, and now B40, all fixed barrels). On occasion, the B40 will win. After about 1000+ rounds, the mainspring broke. A new one with seals is cheap and available from Xisco. Not long after replacement, the washer on the mainspring guide came loose from the tube. This was apparently press fit without flaring the tube. This too was easily fixed, all this leading to the discovery of how easy repair is on this design. Some of this sounds bad but I really enjoy and recommend this rifle from China. By now, some of these "bugs" may have been remedied. One more thing, since the spring is so easily replaced-A slightly smaller wire diameter spring will smooth the piston release and firing action with no measurable loss of power, probably by avoiding "stacking" in the full-cocked position.

Save your money and don't buy a Xisco B-40.

The Xisco B-40 is an extremely accurate underlever spring airgun. At approximately 15 yards I can consistently shoot .25 inch groups with 5 shots while sitting and balancing my elbow on my knee (using Gamo match flatheaded pellets). I am almost 60 years old and for me this is about the best that I can do. When I first got this rifle my groups had been very poor this was due to an overly tight loading port which caused extremely difficult pellet insertion and upon closing the breach block would c ...
