Hey guys, i own a UTG mk96 with the following upgrades:
-455mm Prommy inner barrel
-PDI Hop Up Chamber
-Prometheus Purple Soft Bucking
-Laylax Zero Trigger
-Laylax Teflon Cylinder
-Laylax Damper Cylinder Head
-Laylax 3 Element Piston (Purple)
-Laylax Spring Guide
-Laylax SP150 Spring
The current ammo im using are Madbull 0.40g bbs
So here is my problem:
The gun in its current state is much capable of hitting targets 200+ feet however the hard part is actually landing the shot on the target. The range i have set up at my house is roughly 170 feet and thats what ive been sighting in the gun too. Now the main issue im having with this gun is its consistency. Previously, i have been running the PDI chamber completely stock with no mods and the stock, clear nubbin. At around 170ft, the shots were either right on target (Which was rare), 4 to 8 inches off target (the most common shot), or swerving so far left or right it off target it was embarrassing (1 to 2 feet). I noticed that at around 160ft, 10ft away from hitting the target, the shots either curve left or right; even up or down and the direction is always random. Just tonight i dabbled into DIY modding the chamber after looking at some threads and settled with adding a metal nub made from the piece of metal that is used as the cocking indicator in the original cylinder and shimming the hop arms. With what materials i had available, i was only able to add a shim in between the arms because the best material i found wasn't as thin as i would like to allow me to have three shims in between and to the sides of the hop arms. I added a shim at the base of the arms, attached to the axle, and one that is just slipped into place, near the front of the arms so that the spacing is the same all the way down the arms. After some test shooting, i was able to see a noticeable difference in consistency. The maximum deviance from the center of the target was maybe 4 to 6 inches at maximum and this was every shot, still the target is at 170ft. Much better than previously where the consistency was completely random from on target to way out of whack. Also since i added the metal nubbin, any form of accidental under-hop is non existent. However, this deviance from the target is still happening at around 160ft. And what i mean is that at 160ft, 10ft away from hitting the target, the bb starts to curve left or right or even a little bit upward. If a target is at 200ft or more, the curve away from the target will too great to ever hit a target at that distance. Even at 170ft, hitting my target is a challenge; i might as well stick to my aeg. So I come here to ask for advice as to how i can fix this. It's extremely aggravating to be so close and yet so far away.
Could it be that i need to just add more shims to completely reduce all play in the arms to achieve maximum consistency? My current setup could still have movement. Or maybe is it that im using a 455mm inner barrel and not the correct length of 499mm? Or even maybe my bucking?
Any help or leads to fixing something is greatly appreciated.
Thank you
