I sure did want a QB-78 in .177 and finally got one from MikeInIowa.
Keep in mind, I already own three other QB-78’s, all in .22 caliber. I didn’t have a .177. Well I got my QB-78 in .177 from Mike about a week ago and today finally got the time to play with it. Before I even put the first shot through it, I had it in pieces to see just what was done and inspect it. Let me say first that although I don’t usually work on many QB’s or other Co2’s, I have done a number of them in the past and have written articles about modding the QB’s. Those articles are on my website.
I’ll not discuss what all that Mike had done to this gun as what he does to them is information that he may consider his information. I will say though that what was done was well done and he spends considerable amount of time and effort in the improvements to make his QB’s into what they are. Everything that was done from the valve to the trigger to the barrel was done well. I know the time that it takes to do what he does and for those that buy Mikes modded guns, based on the gun that I got, you do get what you pay for.
Later in the afternoon after it was assembled I ran 8-10 test shots through it and then decided to run it across the lights just to get an idea of what it would do. I had used a single cartridge in it and knew or course that with being modded, it probably wouldn’t last long.
I did an additional 8 shots across the chrony and had an average of 803 with a 6 fps spread. The pellet was Gamo 8.3 Match. The temp was about 83 degrees and the shots were approx one minute apart. Then it started dropping down again as I expected. The first drop was to 782-776-754-726. I decided to stop there to let it set and be sure that the pressure stayed up over the next few days and there are no leaks. My wife ran the pellets over the lights and she fell in love with the gun and has laid claim to it already. Oh well….easy come easy go.
Anyhow Mike…. Ya did good and thanks
