Very little tbh
comes with bearing spring guide (plastic but it is fine they do not HAVE to be metal)
piston head (blue plastic head) seals very well - miles superior to other stock piston heads
The piston itself and the sector gear I am not a great fan of but will suffice for modest 20rps
just a bit of ptfe tape to seal it to cylinder, possible o-ring change if seal isn't astounding
The main to change or consider changing is hop unit - f*cking crap clear one to red element accurate g36/prowin clone type
o-ring nozzle would be wise, clear plastic nozzle is not great
often these come in hot 385fps so spring downgrade or Shortstroke a couple of teeth if using a full metal tooth piston
(correcting AoE blah blah blah)
it comes with 7mm bearings which will be ok-ish but pushing higher speeds past 20rps they can fail at 27rps in under 20k rounds
(well mine did
)
but going easy they should be fine...
If and when they fail replace with bushings and maybe a 16:1 gear set - no need to go nutz
motor isn't great - can replace with shs torque or run for a while on higher 11.1v juice with stock motor
though mosfet for long term use would be wise
those are your options to attain 20rps
It isn't a bad gun - quite solid with plenty of weight, 295/300 barrel with 400mm outer barrel extension option included
think the hop is the most people change as stock one is crap (typical d-boyi hop found in other guns they do)
if you decide to use 380-410 barrel then change cylinder as it is ported for the 295/300 barrel
Taiwangun do them for about 190 Euro front or rear wired
front comes with a good size peq box - rear wired is ergh rear wired but their crane stock - hmmm not the best
bloody thing has a screw at back - weird thing to put in, without replacing screw it is fine but doesn't seem to snap shut 101%
(like I said crane stock is not the best - but not the worst)
Very very unlikely it will not have any trades on it, deffo no trades on EU guns coz VFC/Umarex have these
you "might" get a HongKong gun with trades but I wouldn't bank on it these days, a few years back maybe but doubt if they still doing them with trades
only other upgrade -
A sling, it has some weight 3.5 to nearly 4kg time you bung on some kitchen sink props etc...
yeah sling would be wise if using all day
magazine's, can be a bit picky, numerous 416's with their magwell's can be pickky so may need to use a bit of tape/velcro to reduce mag wobble and fit nice & snug feeding sweet on other mags you may use
not a bad gun, a few qwirks but it isn't that bad and quite nice after a few little tweaks & mods imho
out of the box has its faults, but if you got a bit of common sense it is a good cheap 416 imho
possible parts list:
SHS red nozzle or zci type 21.45mm aprox
Element IN0804 M4/M16 Accurate Hop-up Chamber
SHS high toque motor (long)
lower spring - m100/105 or short stroke if you feel brave but with new piston like:
Metal rack piston - doesn't HAVE to be SHS, the piston guides allow for rather large/fat pistons that don't bind like in some boxes
(shs piston can be a little loose tbh in d-boys v2)
upgrades later on to consider but not needed - ffs just use the bloody thing for a while....
Gears - SHS if you change at some point with a delay clip
7mm SHS bushings
Mosfet
wiring isn't that bad, better than some thin pubic hair stock wiring in some stock guns
yes it could get changed - but jeez how far you wanna go ???
you really don't need to do much - hop is biggest downfall many including myself say
the rest you can leave for a while until she needs it
