TEST 4:
Pre-Notes:
-Going to swap springs to matrix M115 to try and find the missing FPS.
-Upon doing my pre compression test i noticed a leak in the air nozzle.
-It will only leak with the piston, not the blow test. Both open and close in the gearbox shell.
-Decided to switch to Hawk air nozzle, and guarder tappet plate instead to achieve perfect compression.
Parts:
Stock Piston + Guarder Aluminum Ball Bearing Piston Head
Stock Cylinder + Cylinder head (Teflon)
[Hawk Air Nozzle + Guarder Tappet Plate + Stock Spring
Prometheus 6.03 Tightbore Barrel 378mm (+15mm to stock)
G&P Metal Hop-up + Bucking (No nub for test)
Stock Spring Guide
Stock Spring
Stock Motor + Grip
Stock Gears (Re-Shimmed)
Stock Gearbox Shell
Stock Gearbox Screws
Stock Bushings
Stock AR Latch + Spring
Stock Trigger + Spring
Stock Safety Switch + Spring
Stock Cutoff Lever + Spring
Pre test compression:
1. Cylinder to piston head
- Perfect
2. Cylinder to air nozzle
- Perfect
3. Piston to cylinder
- Perfect
4. Piston to air nozzle *Extended*
- Perfect
5. Piston to air nozzle *Closed*
- Perfect
6. Hop-up to barrel
- Perfect
7. Piston to barrel

Average:
333.7fps, 22.9 variance.
Post-Notes:
-Although the compression was good in testing it, it obviously wasn’t in shooting. The FPS dropped by 7.
-Going to put the stock air nozzle back in, and regardless what the testing will show, it clearly isn’t the end all to be all.
-Going to do my original test idea of swapping springs to regain lost fps.
TEST 5:
Pre-Test Notes:
-Swapping in matrix m115 spring.
-After testing the stock nozzle, the compression is horrible, as bad as it was in test 1. There’s no way im going to put that back into the gun as that may be the variable. It was perfect, and now it’s leaking air like crazy. Even though I lost 7fps, i’m putting the hawk nozzle back in with the m115.

Average:
369.6fps, 29.1 fps variance INITIALLY, then gun lowered itself to an average of 343.5fps with approx 60 shots through it, over the last 30 it has a variance of 11.9fps, with 348fps being the highest and 336.1fps being the lowest.
Notes:
-There must be something wrong in either the gearbox shell, or the body of the gun to allow such variance and the inability to consistently chrono over 350fps with any spring, piston head, air nozzle, tappet plate, hop up, barrel, and hop up bucking with perfect compression.
-The wiring also got really hot, as well as the motor.
-Maybe the higher fps unsettles something? Unsettled it can only shoot 350fps?
-The first 10 shots have a 29.1fps variance, but by 60 it dropped to 11.9, which is still a lot higher than any of the earlier tests.
-Potentially the way the spring guide sits on the shell, or moves, isn’t allowing.
-The variances could go on forever.
