I have two JG G3's (yeah, I know it's not the same but still) and they're plastic and pretty decent, I seem to recall that the JG MP5s have a weird lever that sticks up from the handguard to adjust the hop which has a habit of wandering in use.

I have an RRV I've been using quite a bit lately and have found that it's just not great for use with battle belts or shooters belts. It's an old school design which while still valid and great for what it is, was never designed to be run with anything much beyond a riggers belt to hold your pistol holster. If you have a "proper" RRV style rig you should be able to fold up the bottom row of molle and clip it in place to allow for more clearance around your waist, if not then try and place any mag pouches/pistol holster no further forward than your 3 o'clock and 9 o'clock points, anything bulky definitely wants to go towards the back (dump pouch, GP pouches etc). If you're using a pistol holster look at either a drop leg or a low ride mount to give you a bit more clearance. As for the mag pouches ON the rig, I run four double M4 mag pouches (old Eagle Industries type ones with the flaps), offset towards the left (I'm right handed) with a couple of grenade pouches on the left end and a 200rnd LMG pouch on the right (holds my TAGs and launcher). I usually run it with a shooters belt but have changed the pistol mag pouches to slanted ones to get more clearance and run a low ride belt loop with a QLS style clip on the holster which helps with clearance too. MOLLE II canteen pouch holds my Odin loader and a dump pouch at the 7-8 o'clock position rounds it all off.

Good man, glad to hear I'm not the only one!

You assume that these people don't just think NIST is a misspelling of the place where birds live.

FTFY. Things that grind my gears? People. Things that grind my gears on airsoft forums? Airsofters. Especially the ones that have an opinion based on internet rumour and aren't prepared to either learn or admit that they may be wrong, misinformed or not in possession of the ONLY WAY to do something.

Same, I use a GW6900 when I play. It's tough and reasonably cheap if I did have to replace it!

The spring is there to make sure the nozzle seats against the hop rubber properly, that's all. You can definitely use O-rings but they're less forgiving of any magazine misalignment.

Prepare thyself for the infinite rabbit hole of "fucking about with airsoft guns"! Rubber parts, yes hop rubber and O-rings. If your AEG doesn't have an O-ring nozzle it may be worth getting a new nozzle that does (make sure you measure it first and get the right length). Again, all parts that @ak2m4 can help you out with. If the old grease is particularly heavy handed it may be worth getting some new shims and reshimming the gears once you clean it out. Check the bore of the cylinder for any scratching/gouges, make sure the piston head is still secure and that any pad on the inside of the cylinder head isn't loose/worn/damaged. GBB is likely to be O-rings on the bottom of the mag too. Put some gas in it and submerge it to see if and where it leaks. No point changing fill valves if they're OK. Depending on the pistol you may be able to get a specific service kit for the mags (more expensive than just getting a bunch of O-rings but more likely to have the right ones). Again, take pictures and post them up in the tech threads here if you're unsure!

That's a good way to get yourself kicked off site.

Ah the original high rise optic mount! Good shout actually, assuming OP wants to be as cool as the rest of us in the carry handle gang.

That's not entirely true. You can definitely get 6.00mm inner barrels, but the benefits don't entirely outweigh the negatives

@ButcherBill just FYI - you won't be able to buy from that link. They don't ship outside the US, and it's probably ITAR restricted anyway.

Chrono - yes Re-grease - yes you will need to open the gearbox up. Also worth getting a can of engine degreaser from Halfords and some fresh grease (I'm a fan of Abbey Gun Grease LT2 for gears and Abbey Silicon grease for plastic/rubber parts - all on Amazon) As for the tricky ones to work on, go slow, take LOTS of pictures during disassembly and as always - ask questions. Someone here is almost guaranteed to have done a gun like yours at some point!

Gotcha. In that case I'd be looking at the GBRS Hydra style risers. Given the size of the lens on that mask I think you'd struggle with anything that would assume a "normal" cheek weld. Things like the SSG-1 work because they're designed to work with PB goggles for Lycra clad HPA players to slid about on their knees with. Or of course you could just go HPA Hi-Capa with an M4 mag adaptor and give yourself completely to the dark side.

There's two schools of thought; add a specific pouch if you have a need for it and ONLY if you have a need for it, or put any pouches you want on because airsoft is fun and who says what you can or can't have. Many would argue that the average skirmish game needs neither trauma shears or a bundle of rope but it's up to you how you play toy guns in the woods. No-one else. Personally, I like a dangler pouch because it helps protect the middle age spread but also gives me somewhere to stash pyro, or keys or whatever other minor bits I decide I might need.

Pete at @ak2m4 is my recommendation for parts supply. https://www.ak2m4.co.uk/index.php?route=common/home He's a regular here and is always happy to help and advise!

Anything rubber will probably have dried out so yes, as you suspect it's going to be new hop rubber, gas seals etc at a minimum. Depending on what sort of lube and level of maintenance you were at when the guns went into storage then I'd certainly consider a good overall service. Batteries - absolutely. Get some new ones. If you have Nimh type ones then they've been roundly replaced by LiPo (go for 7.4v ones though). If you already had LiPo be grateful they haven't already burnt your house down and get rid! New seals are cheap, just change them over and then you can sell as "refurbished" rather than "serviced but might still leak like a sieve".

I'm more intrigued to find out why they're selling them on Depop of all places!

At least it isn't JBBG... The site appears to be an old farm with outbuildings that have been converted into commercial sublets. The house is likely nothing to do with any of the businesses on site!

Bad shimming and/or timing will make more of a difference. That and an over active Extensor indicis.

Golden Eagle do a plastic receiver as a replacement part for the TM (complete with fixings for the shitty old style split hop unit but they are all ABS (basically a direct replacement for the TM). Maybe see if you can get a Specna Flex receiver but none of them are carry handle, just flat top MK18 style stuff or a 416-alike.

That's what she said! 😂 ......oh, wait

Yep, under new management https://wolfarmouries.co.uk/blog/a-new-chapter-begins/
