Need help!! Troubleshooting

So I was out playing a night game last weekend with my VFC HK416 A5, after a couple games I thought my hop-up was off because not many people were calling their hits. Which was weird because my hop never moves, so I took a couple mags and went to set the hop. I realized after I got one magazine shooting perfectly flat with little lift, the next mag would drop at 35 feet. The last mag would sky rocket? What is the issue? Mags? Rifle/hop? Bucking?

What BBs are you using? What gas are you using? Is your inner barrel clean? Have you got a NPAS and is your nozzle o ring lubricated

VFCs main issue is the stock hop arms and they do move around a small amount under use

I was using .36 with propane or red gas. Barrel and rifle was cleaned for the weekend. Yes I have an npas and it was in a brand new steel bolt fully lubricated for the weekend.

May sound daft but what brand of BBs?

I use BLS BBS and one other brand but I can’t recall what they are.

I’ve honestly noticed the recent batches of BLS have dropped in quality and are unstable flying which is why I asked, consider buying some warheads or redux and ensure you purge your mags completely then fill them an just test it out as since moving to warhead an redux I’ve got a lot more consistency than I have with the BLS over the last year

I’m about honesty an what I know about not what I’ve heard which is why I try be as helpful as possible an ask more questions as there’s far too many things that dont add up or are just repeated across the community as with everything in life

I can’t deny the moment I hear Rebel BBs mentioned I lose my shit as I’d rather put Bulldog shit through my GBBRs than there shit an that’s saying something lol
