this was my first thought, albeit a guess rather than any certainty.

i mean that's better than what i thought which was pretty much that

that one of them ones where the hop unit only has 2 positions?

"worth it" is a very subjective term in this hobby. yes you absolutely could improve the performance of most stock pews, although how much money/time/effort you're willing to spend to get there and wether or not the improvement will be enough for you to justify it is entirely down to you. this is the primary reason to suggest, for the time being at least, leaving well enough alone. as the saying goes "if it ain't broke don't "fix" it". main reason is it's very easy especially when you're just starting out to mess up installing parts or re-assembling the pew which could end up with it performing worse than before (even if the parts are better on paper) or even breaking, which needless to say sucks when you have to go home early because your pew isn't working and trust me that shit gets real old real fast. the best way around is to wait until you have a decent backup. you can either buy another pew then work on your current one or buy something specifically with the aim of tinkering with it and keeping your current as the backup. that said, you can just jump straight in like i did but at least you've been warned what'll happen so my conscience is clear for range/accuracy generally i tend to recommend the following as a rough guide, starts off with the easy/cheap stuff going to the harder/more expensive stuff: -cleaning the barrel on a regular basis, really makes a difference and i'd suggest doing it at least once before each outing. if you start going for tighter bore barrels you might find you need to clean even mid-game day. -good quality heavy ammo, personally i'm a fan of geoffs. weight wise it's a balance between cost/performance, heavier ammo will be better but it costs more and you might be limited by what the hop can lift. commonly folks tend to find the 0.28-0.32g range a nice compromise between price/performance for outdoor work. -changing hop bucking/nub combo, tied into above something like the maple leaf macaron tan+omega nub combo is gonna help spin up heavier ammo and isn't too expensive/difficult to install. -air seal, this is the big step up in difficulty because it involves cracking open the gearbox, so you might want to leave this be for the moment. the best way to check how decent the current setup is performing is to look at the range of fps values it's spitting out (ie when you say "about 300fps" then quantify that as 300fps±Xfps), the smaller the range of values the better. for the ways of checking air seal when assembling a gearbox have a look here. -spring, the reason why this isn't earlier in the list is you need to be sure you're not losing energy to an air leak, you may well find that the power jumps up from doing the previous 2 steps because of fixing leaks. however once you're sure that you're getting everything the spring has to offer and you're a decent chunk under the limit then you could look at a stronger spring. however for the moment sounds like it's close enough to not worry too much just yet. -barrel, we're very far down the diminishing returns curve at this point, so there might not be massive gains to be had here, but this is the point where you might find something like a zci 6.02 stainless might be worth a look at. worth being clear if what you want is a higher rate of fire in auto, or a snappier response in semiauto, and what you're currently using battery wise. for auto rate of fire generally running higher voltage batteries, faster motors or higher speed gearsets are the go-to. for semi-auto response you can boost by doing the above, but a mosfet with precocking can really make a big improvement without increasing the actual auto rate of fire (which can be good for longevity)

depends on the setup, setting windage on an ak for example, or for the mini rmr style dots you need a screwdriver to adjust. not saying you shouldn't do it if you have the chance, just that it's not the end of the world if you don't have the time to get it properly dialed in. yes, this is a valid point, hence why i caveated the "repeatable" part

for lasers you do have a point, but i'd disagree that irons/dots/reticles need to be exactly on, as long as it's a repeatable point of reference (ie not moving relative to where the rounds are going) you can kentucky windage your way into getting good hits.

With a rifle yes, although i do know what you mean with regards to pistols- far enough away where you can't instinct fire but too close to be able to take your time aiming. My solution to those engagements is to respawn

yes that would absolutely do it. the bb in the barrel is a resistance that will slow the progress of the piston (as it works to push the bb out the barrel) so entirely normal for it to be different when there's nothing obstructing the barrel. it's why i tend not to dry-fire aeg's too much. likewise the spring around the barrel pushing the hop unit back is a definite candidate for causing a big air leak if the hop unit is sitting forward of where it should. of the precocking options out there there's the gate warfet and perun ab++ wire in the same as a conventional mosfet (ie using the original trigger contacts/cutoff lever etc), although both will require some soldering.

i'm getting reverse deja-vu, or maybe regular deja vu, swear i saw this thread a while back and replied to it?

piston slap is relatively normal depending on the particulars of the piston/cylinder head etc. however it might possibly be a sign of an air leak (lack of resistance- faster piston louder slap), very hard to say without actually hearing it in the flesh although you can test on a chrono. twanging is a common enough problem, one way to solve it is the use of a mosfet with precocking enabled, which has other benefits as well folks have also tried things like using a longer spring (of the same rating, so it's under more preload)

i used to think very much that way, until a couple of occasions i chose/was forced into running irons only and found myself doing surprisingly well. even if the irons are off you still have a reasonably repeatable reference point for where your shots are going, which is close enough for the ranges we play at.

aoe wouldn't really do that, it'd be more on the rearmost pickup tooth. i'd be wary of videos on the topic, aoe is one of those subjects that you see a lot of people blanket suggesting large adjustments when the reality is the vast majority of pews don't need anything so drastic.

I guess maybe it might be an idea if there's enough traffic, like an owners thread hits X number of pages then give it a mini forum.

Premature engagement Basically the piston isn't fully forwards when the sector gear tries to pick it up, teeth are badly aligned and something ends up breaking. Most common cause is when folk are building a gun thats running too fast for its power, but as @Skara says can also occurr when something like a bb jam is restricting forward motion of the piston. its one of the arguments for plastic tooth pistons, the teeth are an intentional point of failure where a metal rack might push the failure onto the gears.

tbf most of the posts are jokes. just not very good ones.....

Tbf rocket propulsion is interesting topic, has to be given the run of the mill option involves strapping yourself to a giant can of flamey stuff (technical term), setting fire to one end and hoping for the best.....

Well now i know what a bussard ramjet is, thats my thing learned for the day.....

if my memory of nitro powered rc remains valid then i wouldn't be worried about a nitro powered minigun cos i can guarantee it'll stall only when the guy really needs it to be running..... plus even if it worked you'd hear him coming a mile off.....

that is assuming the 22k rounds are from the gearbox in its current state. could well be it's 21.5k rounds through a mostly stock gearbox before the last batch of parts were installed. or 21.5k rounds through a different gun before the aster was transplanted into this gun. skeptical hamster is skeptical.....

given the standards of youtube review channels in airsoft i genuinely wouldn't be surprised if they couldn't fill 50% of the watchtime of a mosfet review talking about how ambidextrous it is.....

you mean like having burst fire? because there's a few will do that. most will only be able to do 2 selections, given it's relatively rare to have an airsoft pew with a 3-position selector (that is 3 firing modes+safe). for internal mosfets it'd be redundant, as setting things like fire rate, precocking etc are tied to the properties of the gearbox/motor (ie you won't need to change them if you're not changing parts) for swappable mosfets i can see where you're coming from, the ability to quickly set between guns so you can have one mosfet that works for multiple guns, but then that means folk wouldn't need to buy multiple mosfets which ain't good for sales

that's airsoft for ya...... sadly a big barrier to innovation in this hobby is that anyone who tries does so in the knowledge that if their new thing is any good, it'll be cloned almost immediately- take a look at the odin m12 saga as a perfect example, some places you could nearly grab a clone before you could get your hands on the original.....

won't be too long to get ukara setup, so might as well wait. it's a pain i know but that's just how it is. sadly that'll be much harder than you'd think it should be. frankly we're lucky that internal gearbox parts tend to fit relatively well, but getting large scale components to play nice is a whole different ball game- take a look at the stuff fusion engine users go through to get a "standard v2 drop-in" to play nice with a given receiver set.

if i had a penny for every "broken misfeeding pile of junk" that shot just fine when you gave it a mag full of geoffs....

If you wanna spend money and learn to tech your first purchase should be a second pew, either a backup to be left as-is or a boneyard gun to learn by fixing up. Either way having a reliable backup gun to pull out when the latest teching experiment fails is infinitely preferable to the walk of shame. Trust me that shit gets old fast.
