Tuneup Guides

KL-B3 Fast Deer.

Tuning this little gun is a fun project not requiring a lot of know how or experience. A great father and son or husband and wife or family project. A great place to start learning what make a springer work. The Fast Deer is not complicated but as with any disassembly, watch how it comes apart, especially small parts. Don't lose parts because they are hard to replace. Download file here KL-B3 Fast Deer Tune-up


Another good starter in the DYI category for tuning. A little more power and a little heavier construction, the B-4-2 is a good light hunter plinker when tuned. It is an underlever cocker that is another "get some experience" gun for someone starting out in air guns. It has it's own little quirks and kinks, but that's learning.

The B-18/19 is a roughly constructed gun internally when manufactured. Although a fairly good gun out of the box, it can be made into a great gun. Tuning the B18/19 can make this gun an excellent shooter if done properly. The time that it takes is a great investment in making this an inexpensive into an all around plinking and/or hunting gun, with power and smoothness whether in the .177 or the .22 caliber.

For the Do-it-yourself persons, it is an excellent gun to tune providing you have the proper tools, mechanical ability, and equipment, and dedicate the time and care needed. This tuneup guide provides all of the information needed to do a good job and make your gun into a personal prized possession. Just download the file and get to work.

So you can't hit the target there's something wrong with my gun. I doubt it. It will more that likely be something wrong with the shooter, the sighting system or the pellets. Here you can find the information for setting up scopes, the whys; the do's and the don'ts and how to shoot using the proper shooting techniques, and pellet information, and how they relate to accuracy.
