that just shows another hole for dirt to get in!

is that image flipped? looks like the bevel is on the right-hand side of the box, it's normally on the left? also what the hell is going on with that massive hole in the side of the box? looks like dirt city

not really familiar enough with the g&p recievers to offer any tips there, it's entirely possible the box has been pulled before but the same box reinstalled, broken dust covers are a very common thing for the ar platform, could even be as simple as pulling the upper to clear a jam from the hop could cause that. if you pop some pics of the rest of the gun/reciever someone might be able to chime in recognising it. the tricky one with piston teeth is often they can have the first tooth removed for engagement. usually your "standard" is a 15 tooth (https://www.ak2m4.co.uk/internal-parts/pistons/ra-15-tooth-piston), however with the first pickup tooth removed you end up with a 14 tooth (https://www.ak2m4.co.uk/internal-parts/pistons/rocket-14-5-tooth-full-piston) you can also get the likes of the 14.5 tooth which has only half of the first tooth removed. that's not to be confused with short-stroking, where teeth from the front of the piston are removed to reduce the distance it travels (teeth are also removed from the sector gear), that's usually done for high speed builds to prevent premature engagement (when the sector spins so fast it goes full circle before the piston has moved all the way forwards). in general they tend to be pretty standard, although as with all things airsoft sometimes you'll get one that's slightly too wide for a given gearbox which ends up tight. my go-to would be the likes of the shs 14 tooth. the one that might be tricky is the piston head, i have it rattling around somewhere in my memory that the g&p's are a different bore to standard? it's been a while since i've worked on one so i could be thinking of another brand.

tbh there doesn't appear to be anything wrong with that gearbox internally that a clean, regrease and the usual air seal/shimming/aoe checks wouldn't solve. have a look here for a general idea of things to be looking for: trigger contacts fouling up is very common, a powerful battery will make it happen faster/risk burning them through, but it'll happen to any standard wired gun if used long enough. the solution to that is a mosfet, either something basic (like the nanoasr) will just protect the contacts or something fancy (eg the warfet) will give you the fancy precocking etc. ^pretty much what i'd be thinking of doing, also all those things are conveniently available from https://www.ak2m4.co.uk, and no he's not paying me to plug that link. it really depends on your priority, wether you just want to get it working or if you want to get her up to a good shooter. that piston isn't in the worst condition, definately usable but i'd probably look to swap it out anyway, but then i'm obsessed with accuracy so anything less than perfect air seal is a no-go for me. also perhaps consider treating her to a nice zci 6.02, ml macaron and omega nub. assuming the gun it came out of is also a g&p then you're looking at a pretty sweet m4 all things considered.

think that was @gasman? dont recall him testing bio's specifically. regardless: is the truth that should be adhered to.

holy bore offset batman j/k i run russian optics, i know both sides of the argument

that may also be a factor.....

i'm kinda the same, dealing with a flat 1j limit i'd rather put the effort into getting an assault rifle up to the same standards then at least i have auto if required. however, some sneaky play with a bolty can be fun if you're in the right mood. especially when you don't need to worry about med.

i do tend to go spur first, but that's more to place a limit on the range in which i can shim the pinion to (eg if the idler needs say 0.3mm under it then i can't put the bevel lower than that). problem is when that limit isn't enough, or as in this case even with the smallest possible amount under the bevel it's not ideal.

so the kid was banned from the flight for (accidentally?) sending a picture of an airsoft glock, in a country where the legal civilian ownership of glocks is a thing let alone legal ownership of toy replicas of aforementioned glock, which wasn't even his? man folks overreact these days......

it could be, it's hard to tell these things from vids sadly the problem with aftermarket shells is they can have their own issues, for example with the mounting of the motor cage or general fitment of the shell into the gun. you could try manually countersinking or finding a smaller pinion, although if there's a tooth profile mismatch that can be its own problem.

ahh, that makes more sense. what gearset/pinion is it?

0.5mm is a thick shim? normally i'd start with 0.1mm under a gear then add from there.

hmmmmmm, the one gun that might tempt me back into pewing again...... i mean if it shoots anything like the s&t mosin does out of the box.

yep. especially when different colours are involved. sounds like people are complaining about being outplayed...... yeah i'm not a fan of it either, i usually ask them to stick it somewhere out of the way, under the sight block of an ak is a handy spot for such stickers.

not personally (discounting the pilfering of kit by squadmates done in the name of humour and always returned), however i have heard of stuff getting pinched, including a double barreled 1911..... its surprising to me it doesn't happen more often given people just leaving their kit strewn out across the safe sone, rifles, pistols etc. personally if it's not on me it stays locked in the boot of the car. i do recall one day stumbling across a gas vector mag just lying inside a building, normally i would ignore such things but in that instance i figured "if i pick it up at least i know a theiving bugger hasn't", you've never seen such a look of relief when it was re-united with its owner.

Indeed, but that doesnt mean shooting for the head when you have a full silhouette presented isnt a dick move.

Not gonna lie i was wondering if it was me or borg having the "woosh" moment until i saw the second page But yeah, thats sadly not an unheard of level of ignorance. I mean by that logic nobody should ever die in a car accident because cars only go like 100fps on the road......

Yep, as you described it so well: "safety theatre" Ofc i dont know what the answer is, every approach and method has its flaws, not sure its possible without either having more staff than players or finding a cure for human dishonesty.

In fairness the piss discussion was interesting. Now theres a sentence i didnt think i'd be saying today, or, well, ever......

yep, some folk are just too persistent. ok sure if it's something weird enough that you're talking a very small market then ok you might expect it'd take a while to shift but run of the mill kit? think the longest thing i had listed was the f2000, and granted it ended up going for less than i'd have liked. but dont think i bumped it more than a couple of times without also dropping the price.

that mean i can bomb down the motorway at 100mph and if the cops pull me over just say "i was aiming for 70"? the limit is the limit, any variance is between [actual empirical velocity of bb according to physics] and [what chrono says bb velocity is] which we generally take to be an acceptable error for a working chrono (although as is the topic here how does one be sure if it isn't properly calibrated) this is indeed true, and part of why being a few fps under the limit isn't the worst idea given how if said battered and tatty chrono is out by 1fps site will the see the reading and say "begone foul cheater most depraved and despicable of creatures, may you be forever banished from this place and a curse laid upon your house unto the 7th generation" meanwhile next in line, jerry joule creep sails on through..... they might not understand it but come hell or high water they're gonna enforce the shit out of the bit they do understand....... god that sounded bitter

forum was only down a few days, surely we're not all bored enough to resort to talking about..... politics......

shots fired! don't worry, he's got a gbbr he's almost out of ammo already.......
