So having had my chrono arrive today I decided to test it before replacing a few bits.
First chrono was around 230-240 FPS, and seeing as the rif is shooting a lot better than when I first got it im guessing it must have been sub 150 to begin with.
Anyway, having double checked shims, replaced nozzle, piston, bucking and nub a quick re-lube, it is now consistent between 308-310 FPS. The air seal on the cylinder isn’t perfect and a bit of ptfe has been put in for now. But I think once I replace the cylinder head and possibly put a tight bore barrel in I could get it upto 330. However I’m happy where it is now and shall leave it be until I’ve used it a few times.

So I ended up picking the one with the hood. So far I’m quite impressed with it for the price.
Feels solid and secure on the mount. zeroing feels solid and secure and clicks nicely with each adjustment. Dot is clear and visible on all 11 settings and I can’t see it being an issue in bright light.
looking forward to a good game day to get a good trial with it.

Funny i was thinking there about the irony that i dislike the l85 for being too damn heavy
In my defence its only heavy after i plastered it in stuff that looks cool but had limited usage in outdoor daylight games.....
and then the idea fairy struck and was like "you should definately mount that gen1 scope on it too just to really go over the top"
Haha sound like a great idea at the time! And rule of cool counts for a lot! 😂 -
Haha I did think it when this one arrived! Definitely be done exercise after a full game day!

Very true, this is a very bulky side mount also.

on a siderail those super cheap 1x30 tube optics look kind of decent, poor man's pk-a:
granted they're *ahem* "airsoft grade" when it comes to parralax at least going by the one i have which is presumably churned out from the same factory.
Yea I was looking at that one, or possibly this one;
JASHKE Airsoft Red Dot Sight Scope 1x30mm Holographic Sight Rifle Scope Sights with 11mm/20mm Weaver/Picatinny Rail Mount for Hunting https://www.amazon.co.uk/dp/B081CS6SDC/ref=cm_sw_r_cp_api_fabc_N58B62JVZ1R70DF1R3RF
or just a standard mini red dot.

Yea, it did originally come with a mini red dot which looked ok on it, was just knackered. Will probably get something similar.

tbh, red dot.
the main thing magnification is useful for in airsoft is shot-tracking, but if you've got the gun dialed in and are shooting at an honest target you can do anything at airsoft ranges with no magnification.
how are you planning on mounting? siderail ris/top cover or gas block?
Red dot it is then, cheers.
I have a 20mm rail mount adapter that sits over the top cover and also has a side rail mounted.

Howdy,
Looking for recommendations for a mid range sight, its for my AK74 so looking for something with a slight magnification but not huge. Also as I'm new i'm not looking to keep it cheap for now until I know what style suits me. Any recommendations/pics of similar set ups would be appreciated.
Many Thanks

It has a hell of lot to do with Brexit; while UPS may carry some responsibility, most of this is down to entirely predictable issues around border controls and being outside the single market. Entirely predictable to everyone except the UK government, that is.
Yup agree as piman said, it was predictable and most other couriers and services have continued with very little delays or interruptions. UPS it seems to have had their heads in the sand and did not prepare for it well at all.

Cheers, I was thinking either a perun ab or a merf 3.2 originally. Or I may just go simple and put a gate nano in for now.

Mosfet with precocking would be worthwhile if you use a lot of semi, otherwise i'd say go basic (ie no active braking) as ab can cause bad trigger lockups on v3's.
Thanks a lot for that advice as I was actually looking for one with active braking. Will just go basic.

sensible move, no sense paying money to fix something that ain't broke.
generally the nozzle is the one thing that can't really be improved that easy without a part replacement, especially the ones that don't have o-rings as standard.
worth pulling everything except the gears from the box when checking, you also need to remember to try it with the box tightened up as what might be perfect with the box held together can lock up tight when you bolt everything together.
sometimes these things happen, if i had a penny for every time i've taken a broken thing apart, found nothing whatsoever wrong with it, put it back together and it's worked again......
yeah that's weak magnets for ya, if the rate of fire is good enough don't need to replace it on that alone though.
little tlc goes a long way, like i said worth checking the air seal first because otherwise you'll end up hauling a much stronger spring than the fps you're getting merits.
plus it'll go miles to helping accuracy, and by extension effective range- the way to tell is shot-shot consistency being much lower than before.
Cheers, yea the nozzle currently fitted seems pretty worn and doesn’t have any seals so I’m thinking to replace with a aluminium nozzle either single or double o ring.
The ROF is ok for now, I think I’d rather put the budget into a nice mosfet and chrono for now. Maybe a few games down the line I will look at further upgrades to improve the rof, 13:1 gears etc, but for now I’m just aiming for good consistency and reliability.

So having done some more research and studying I decided to go back into the box today before I jump the gun and order bits I don’t need. Went further and pulled the trigger assembly apart also.
so I wouldn’t say the cut off is worn, I also replaced the seals on the piston and cylinder and air seal is now good except with the nozzle, measured it up and shall be replacing the nozzle.
I was also a bit less sure that the previous shimming was as good as I thought and it seems like it was shimmed too tight as after I had shimmed it the gears seemed to be able to freely spin a lot easier than before and sounds good.
As for the over cycling, it seems to have all but stopped. Not sure what or why but it is 100 times better than before. I think fitting a mosfet to the unit should solve that issue.
apart from that it’s just the nozzle to replace and possibly the motor as there is very little resistance when I spin the pinion by hand.
quick re-grease and test fire and it is so much sharper and the FPS has definitely shot up (waiting on chrono to test) but the difference is really noticeable.
-
Yea it’s definitely had some history but I do like it and it’s turning into a little first project for me. I’m excited to see what I can do with it. Already learnt a lot from it so it will be good to see what I can get out of it.

are you sure the cutoff is worn enough to be causing the overspin?
reason i say is cutoff levers can be a right pain to replace, one of those parts that really highlights the "compatible-ish" nature of airsoft.
the piston seal can be heath-robinsoned by stretching (or if your fancy replacing) just the piston o-ring (assuming the piston itself is in good nick), likewise ptfe tape (or doing it properly new o rings) on the cylinder head can sort that end. metal rack isn't guaranteed protection (and arguably a sacrificial plastic part can be good) but if the original is chewed up then might as well (you may need to glue the rack in yourself or it can get ripped out)
i presume the spring guide replacement is to a bearing type? that is a worthwhile move as it means you can lighten the piston by not having a bearing in that end.
spring i'd leave for now until you sort the airseal- could be perfectly good just the air loss is killing it.
bucking/nub certainly a good option, ml macaron+autobot is my go-to combo these days.
nozzle make sure to check the length, unfortunately not just the length can vary but also the internal diameter so if you're gonna change the head and nozzle try and get the same brand.
mosfet wise, plenty of options for cheap and cheerful but i tend to like putting something like the nanoasr in as the wiring is identical to the higher end gate mosfets so you can easily swap to something like a warfet later down the line.
Cheers, yea I had put ptfe behind the piston seal which sorted the air seal and to be honest the seal was fairly good with the nozzle so I should probably leave that alone I just wanted to replace it so i'm not relying on the ptfe for a good seal.
Yea I am planning on fitting a ML macaron 60 and the spring guide is so that it is a bearing type. The spring i was going to replace as it seems very short and has a very rough cut job.
The cut off is completely rounded so I am presuming it is causing the over cycle however the mosfet addition should also help with this.
I do need to buy a chrono as well and want to have it at the start before I begin changing anything.

is it really that badly worn that all of that stuff is gone?
because if it really is then it'll be cheaper and easier just to buy a whole new box as a drop-in.
No not everything is that worn, piston seal is poor and old so id like to upgrade that to have a metal rack, the cut off lever is worn and does need to be replaced, and id like to add a basic mosfet as with the worn cut off it is over cycling. the barrel and bucking are just upgrades id like to do rather than are absolutely necessary.

Cybergun AK74Us -
So after stripping down and seeing that a few things in my gearbox need upgrading, I am debating either just replacing/upgrading the worn parts or aiming for an increased ROF. Current basket/upgrades;
Piston & Head
Spring & Guide
Inner Barrel
Bucking/Nub
Nozzle
Cut off lever
all Springs
Mosfet
Current gears and motor seem fine however I am contemplating fitting a 13:1 gear set, bearings and new motor. Has anyone done similar and recommend any other things to consider or parts? I currently have a basket on AK2M4 just waiting on pay day!

Welcome
Congrats on your new pew and the work you've done on it.
You can get red dot sights quite cheap.
This one is quite good for the price: https://www.amazon.co.uk/Airsoft-Goggles-Tactical-Suitable-Picatinny/dp/B083D2WL7C/ref=cm_cr_arp_d_product_top?ie=UTF8
Or just have a look at our classifieds
Thank you.
Yea I’m keeping an eye on the classifieds. Going to buy most of the replacement parts and upgrades on payday and hopefully be happy with it all once that is done. Then onto a nice little gbb side piece.

There are some options, but be careful when picking the repro zenitco stuff as the handguard dimensions on some patterns of ak are different to others and even when it is the "right" type you may need to crack out a file to get it to sit snug.
Will do cheers, I don’t mind a bit of tinkering to get them to fit.
put a new a battery in the rds this evening and found out the sight is kaput. On closer inspection the emitter had been all scratched up as if it had been attacked with a small screw driver in the past. Can’t help but start to feel slightly ripped off now but hey that’s the risk with buying second hand.

tbh the side rail looks pretty decent as-is.
if it were me i'd lose the torch and if possible the side section of rail.
if you wanna go the tactical route then some repro zenitco on the frontend will give you somewhere to mount a torch to (which will also be more convenient for activation)
Yea I was thinking to move the torch to a front side rail along a grip below. The rail is very chunky and can’t be removed from the mount.

I’m not sure tbh as it’s for an ICS. But someone on fb has messaged me with a cyma one. Thank you tho.
