Well mb03 accuracy issues after upgrade

I have a Well mb03 that I’ve been upgrading mainly to achieve more range. My upgrades include:
-Maple Leaf VSR-10 90 Degree Trigger Set for VSR-10 Sniper Series (2020 version)
-Maple Leaf 90 Degree Piston for VSR-10 Series - Black
-Action Army 6.01mm VSR-10 / M24 LTR Barrel 512mm
-Action Army m170 spring
-Maple Leaf Hop Up Chamber Set VSR-10
-Maple Leaf 70 autobot bucking

I’m currently trying out some Norvritsch .36g bbs. I’m using .36g based on what I’ve read here in accordance with my barrel length.
The issue I’m having is after all these upgrades I’ve completely lost all accuracy. And when I say completely I mean I have maybe 5ft groupings at 120ft. I had decent accuracy after the trigger and piston upgrades. All other upgrades were done at one time. I have Teflon tape at the bucking to barrel connection and on the threads for the cylinder head. I’m not sure if it’s an issue with the gun or if I need heavier ammo. My experience with aegs that needed heavier ammo normally resulted in bbs flying straight up as if they were overhopped. This gun is shooting bbs all over the place. Any advice would be greatly appreciated!

I also agree with Mr. SiliconeSword with the heavier BBs, and the action army hopup chamber with a possible Maple Leaf Omega nub, or possibly a Masada nub if you don't want to try your hand at an SS-nub. I would also look into compression issues as there is no indication that you have checked the compression since you worked on it last.
id check the compression on the cylinder by itself first, then check on the barrel, then repair if there is a problem. it could be getting unstable, but you would have to chrono to be able to tell what the muzzle velocity is.
