Feinwerkbau sport 124 manual
I definitely like the feel of the new shot cycle. The so-called "lock time" really feels shorter and the recoil is now straight-back, more similar to how a gas ram, like a Nitro piston feels than before. The shot also seems to cycle much more quickly than the stock configuration. The spring is also much shorter, so it seems like it has less length to move around inside the gun. First, it removed all of the twang and most of the vibration, due to, I believe, the tight-fitting spring to the guides. Like I mentioned, this kit has transformed the gun's firing characteristics and it feels like a new animal.

Ok, its time to give some results from the FWB 124's tune with the Maccari Pro Mac Kit. I had already lube-tuned the gun when I first put it together, so the rest was pretty much drop in, while adding a dab or two of moly to lube things up. Its pretty easy to work on, other than the rear safety sort of getting in the way of compressing the spring in the compressor. I hope you all enjoy the pictures of the insides of the FWB 124. Now THIS is how springs should fit, not all loose like from the factory so they rattle around and cause all of that twang! The spring just barely went onto the rear and front guides and I really had to use some muscle to wiggle them on. One thing I noticed is that these things are now SUPER tight compared to the factory pieces. First to go on is the thick metal spacer, then the new spring. The trigger is somewhat unique in that it also has the rear guide on it.
Here's a picture of the whole spring assembled just before reinstalling it into the gun. Its nice to add this to a pivot bolt when re-installing to make it nice and smooth! Notice the Maccari moly in the left of the picture. It wasn't the right size, so the barrel was still loose. In the next picture, you'll see the new barrel pivot bolt and screw along with the old one and the silver-colored screw I used for the time-being. Especially since the new one from Air Rifle Headquarters cost $35! With a loose barrel causing a weird lock up and some vertical stringing while shooting, I decided to bite the bullet and do it right. If I had known how much this little screw would be problematic, I would have offered less for the gun. Unfortunately, the tiny screw fitting into the end of the original barrel bolt to enlarge the hollow end, thus tightening it, was lost in the process. He and his friend gave up fixing it after sending the factory spring into the garage wall while attempting to fix the original seal. This gun came to me disassembled and was basically a box of parts when I got it from the previous owner. I also bought a brand-new pivot bolt and screw along with the tune kit. Since a picture is a thousand words, here are a few:ĭisassembled gun with picture of new spring kit and factory spring:Īs you can see, the new kit with its different configuration, can really change the whole dynamics of the interaction of the spring and piston with the differing stiffness, length and spacing. As an added bonus, this kit not only smooths vibration, but generally increases velocity as well with the stiffer spring. Some of the lost length is made up for with the spacers, but overall, the length of the spring kit is shorter than the factory spring. Also, as you'll see in the pictures, the new spring is much shorter than the original and is a bit stouter. Its tight tolerances are designed to cut down on the vibration of the spring which produces the classic "twang" in most springers. This is a custom made kit from that comes with front and rear guides that are extremely tight-fitting. I decided this gun, and not my "new-to-me" San Rafael would get the kit since it had the most to gain, being the roughest cocking and least accurate of the two. I finally got around to installing the Maccari Pro Mac tune kit in my San Anselmo "Cobra" FWB 124.
