horrible consistancy with mk16

[this is bull]

ok so i have a vfc mk16 and i am using bioval .27s and im getting horrible accuracy.my upgrades include a firefly hard bucking,bore up cylinder set,aluminum air nozzle,pdi 190,and a stock vfc 380mm barrel.i was wondering what i can do to improve accuracy i can fire 3 shots that follow the same path then the next 2 ether over hop or under hop.

crap batch of bbs maybe.

highly doubt that, there biovals

never heard of em before but every company occasionally has a shit batch no matter how hi quality they are. Try bbs from a different bag or another brand all together.

I can't comment much on the VFC Mk16 specifically...but I'd try a different hopup rubber/nub combination. Looks like the hopup is taking effect...just not the same amount each shot.

I don't know if the stock barrel is a tightbore but that may help as well.

I had a setup that was shooting ~400fps w/0.20 and it was just so-so ok. Very consistent chronograph readings 397-398fps over and over...so that was a strong indicator that it was the hopup rubber or barrel.

I swapped in a 6.03mm tightbore and the overall groups shrunk but I still had these wild flyers.

I swapped from a Guarder Black rubber to a softer Guarder clear rubber...and the group didn't really shrink much...but there weren't any more flyers.

Still worth trying a different bag/brand of bbs...even though the Bivals are supposed to be magic super bbs.

i changed the bucking but that didnt really help,i used a guarder bucking.another reason i dont think its the bbs is because the horizontal is great.should i get a promy hard bucking or a 9ball.

6.05mm barrel out of the box on that one.
