Go back to Krytac hop ???
The issue is some hops don't like some guns
Also some bucking installs the hop bucking can get pinched/squished or the actual lips protrude into hop unit feedwell, then lips catch on bb, fold over and bb's don't pass through the lips to make into into position under nub etc...
To simply say I installed this and it don't work is almost like asking for next week's lottery numbers
Remove hop barrel assembly...
Look into feedwell see if you see any bucking that might foul
Drop a BB in there - does it drop in ok or catch on lips
Then see if you can lightly push the BB through the lips carefully with a thin stick jam rod or something like the nozzle pushes it through
If you feel resistance, more that just a slight resistance the bucking is pinched and though it might not seem ultra bad, a pinched bucking or tight opening will restrict the bb's chambering into barrel
It is a classic problem, madbull bollox that works for some instances but not for every gun
But my mate....
We'll get your mate to install it
But it works for his gun
You got same gun, same mags same bucking etc...
Well no...
There you go then and even if everything matched a bad install is a bad install plus the ever so slight risk of something lemony occurring can't be ruled out
Hence sometimes shit works and sometimes it don't
If all else fails you go back to stock, rebuild new assembly and try again
(Wise to leave old stock hop/barrel/bucking as is
Fuck about with new crap and go back to old stock stuff (still intact) if all else fails
There is a hop tutorial by bingo works or something which might help test/identify something's but then again sometimes shit still may not work without a lot of paracetamol and still not guaranteed
For instance some bucking's really don't like some hops or vice versa coz stuff can get pinched or a bitch to install. This hop/bucking/barrel combo can be just as challenging as any gearbox
But there's only 3 parts - yeah and what fun just those 3 parts can give you if they don't want to cooperate
Best of luck
