WE Tech M&P Big Bird Hop up

[Stryper]

Hi there,

I'm very new to airsoft but looking to start skirmishing in a few weeks and hopefully for a long time, I picked up my first GBB sidearm (We M&P Big Bird) though I have an issue with the hop up.

I know there are some issues regarding the factory hop up, but I was curious as to just how much a hop up wheel should be able to move? I can rotate my wheel about 45 degrees before it locks (about 3 or 4 notches) but I'm not sure exactly how much this would impact the BB. Is it minute adjustments make a big difference or do you have to rotate 90 or 180 degrees to see a difference? Currently my rounds have too much hop and I'm having to aim low to compensate; even at around 20 - 30ft.

Im using Biosphere .25g Bio BBs, the barrel is clean and the gun is well lubricated.

Many thanks,

Ryan

I always use small incriments of hop so will take a little while to dial the hop in

The we bug bird stock hop is cack. The two options are open the hop (easy if you can wield a screwdriver without stabbing yourself) and take a tiny bit of metal off the tab the runs in the hop wheel. Or buy a we small bird hop and for that as they fixed the issue. Check out the link. I LOVE my we m&p and would never part with it but the oem hop is shit till you rework it.

For my little bird the hop wheel moths about 0.1cm but makes a massive difference but mines is a different gun that is the same

Little bird has a better hop arm inside, they altered the shape so it works waaaaay better.
