Some of you might remember the promised parts for L851 from PowerUpgrade.cz - well they are ready to ship since a few weeks, but PayPal is slowing down the whole process - their account is still not up yet. But it's not going to take more than a few days according to PayPal. They have a new aluminum spacer, as some of you requested - made of aluminum, indestructible and yet lightweight (5.2g, the plastic spacer had 2g). With some improvements (and it makes a good contact between the piston head and piston, no chance that the parts would move - which can be an issue with home-made spacers)

I have the plastic spacer and works great, but don't confuse quality plastic with chinese "plastic" that is used in airsoft parts. I did ask about the specific plastic type, and it's Ercetal C - http://www.dotmar.com.au/products/acetal/ertacetal_c.htm . As you can see from the manufacturer's description, it's that tough that it's ment for gears. They could make it in aluminum or any other metal, but this would just add weight to the piston (more weight = more possible damage to other parts by the piston). So, using metal wouldn't make any sense at all (pistons are also usually from plastic, ju

Yes, I am pretty sure they will offer a kit like this. The problem is that the Army cylinder itself has the wrong size, it's a little too wide! I noticed this when I was replacing the piston head, the gun was loosing a lot of air pressure - because there was a gap between the piston head and cylinder. The difference is very small but you are going to see a difference when firing. Of course, a little wider O-ring could solve this - but the best is to replace the cylinder with a standard type. That's why Powerupgrade is going to offer a full set, so you can replace it all at once, and you won'

I don't know the pricing of L85 parts yet, but the spacer with screw costs 4-5£, the whole set on the picture is about 41£ (I don't think you get cheaper parts made by a custom shop). I hope I did the currency conversion right . I asked and they told me that PayPal should be ready by the end of this week, so you might be maybe able to order it quite soon...

Hi Domz, I am in contact with the owner of Powerupgrade.cz, the Czech version is fully updated but they are working on the English translation. It should be ready very soon. They are going to sell whole "upgrade-sets" for the Army R85A1. The set will probably consist of precision made nozzle, cylinder head, cylinder, piston head, spacer, piston. It's almost ready. Of course, if you just need the spacer (along with a longer screw), you can just order the single part. The set might look like this one (this is for a M4), all parts are matched for perfect fit. Different pistons are avaiable

I've found out something interesting today, it seems that Army made some changes to the latest batch of R85A1? Someone posted this pictures of the internals of a stock R85A1 which he bought recently. Improved design, black plastic instead of white, added metal bushings. The piston is also made of black plastic, but it broke anyway after few shots... The spring guide is now made of black plastic instead of metal, but at least they kept the metal bushings...

I've got some got news for you, custom parts for Army L85A1 are coming ... I asked at a Czech custom shop (http://www.powerupgrade.cz) and they made a spacer for me, exactly the lenght I needed, made out of some durable plastic. And it was much cheaper than from redwolf. They told me that they are going to produce all the parts for the G&G and Army L85a1, mainly for the UK market. They are going to make the cylinder head, which is a non-standard part (I couldn't find it anywhere) with a new cylinder, the piston head will be made a little wider than standard, because the cylinder

Hi all, I haven't been here for a while. My L85 works fine - I replaced the piston, piston head (+spacer),TM sector gear, M110 spring and hop-up bucking. Semi isn't working for the most time, so I don't use it all. Things I found out - the remaining two gears are not TM standard. Anyone knows a gun that uses the same gears? Can someone tell me what type is the nozzle and cylinder head? Thanks.

You need a standard 16 tooth piston, but not TM (they don't fit too well, they aren't wide enough), maybe also a new piston head... A friend made me that spacer for $7.

Damn!! My piston just failed 8 hours before skirmish . My 16 tooth piston hasn't arrived yet, so I can forget that skirmish.. this sucks. The piston didn't brake into parts but the first tooth (the long one) is grind away, so that the sector gear can't get a grip on the piston. I'll take pictures tomorrow. Two guns of three have broken pistons. Replacement parts ETA coming week - I'll let you know how they work.

It broke after a few hunders shots on one of three guns we have. The two are running fine after about 3000 shots. The hopup doesn't really work - adjusting doesn't have real impact on the accuracy. I bought a systema hopup bucking, I will test it in a few days - I am going to change out the whole hopup chamber if it doesn't help. We are replacing the pistons and sector gears on all three guns, to make the gun more reliable and to be able to use standard parts. Blowback is disabled on all three guns.

Did anyone try to put a new hop-up chamber in the R85? One member reported that G&P chamber didn't fit. What about the element hopup?... I was able to replace the sector gear for a standard TM sector gear, the disassembly of the mechabox is quite easy. I am going to replace the piston and piston head today...

One question about the hop-up unit, I removed the inner barrel along with the hop-up bucking, a small rubber part fell out. It seem to be the part that pushes against the hop-up bucking. It's the small part on this picture: http://www.x-guns.com/Prd100/922-082-S.jpg Was it somehow attached inside the hop-up unit? How to install the small part back?

If anybody finds a cheap way how to buy spare tappet plates for the R85, then please let me know. Thanks.

Has anyone else tried TM pistons? Because one member reported that the TM piston wasn't wide enough... I will get some pistons within 2 weeks, along with a new piston head and a new hopup rubber, I hope it will fit... If it goes OK, then I will get a tightbore barrel a new hopup too.

You can use the gun in the condition it is now, just take out that little hook so you don't loose it (or it could fall into the gears and damage them). The blowback doesn't work without the little hook and spring, but the whole gun will be OK without them. The best is to remove the whole metal block on which the hook is placed... The blowback won't work without the small spring - but don't worry about it, you would loose it anyway later. You can go to the skirmish, it will work the same as with the blowback (even with a little higher ROF, because the blowback slows down the piston). The

Remove the blowback for the skirmish - it won't help you in the fight either . As for the small hook, it goes here: There must be also a tiny spring which goes between the hook and the metal part. It's held in place just by tons of grease. Notice the small red circle - there is a screw on the side, if you take out the screw then you can slide the whole blowback out and trash it , don't forget to put the screw back. Your picture is very blurred but I think I see the bent blowback plate. There are very small tolerances between the plate and the side of the mechabox - I don't t

You can try to add your debit card, but there is a PayPal spending limit and you will need to complete the Expanded Use Enrollment to get rid of the limit.PayPal will charge you 1-2$ from your card and you will then use the transaction number as the code. But it takes 2-3 days until PayPal charges this ammount from your bank. There is also a bank limit for debit/credit cards, you would have to ask your bank but I am pretty sure it's more than you would like to spend...

That's the Expanded Use Enrollment. And you are right, if you have just registered on PayPal then you need to go through this. Well actually, you can pay with paypal if you don't do this but there is a limit (500$??). I don't have any bank account registered with PayPal, just my debit card...

Hmm, that sucks.. Hopefully it's something just with that single mechabox. I have ordered three special (custom) pistons for the R85, that would be a serious problem if they didn't fit...

You need to register a credit/debit card on PayPal if you want to pay directly, without the need to first upload money to paypal.

Get the spacer and use a standard piston (and buy a quality piston head for it). You will also need a standard TM sector gear. Replacing it with the same piston won't help, it will break again.

Yes, sometimes it's quite hard to insert the rear pin - the two bodies have to be alinged correctly, the best is to press the two parts of the body with two hands and knock the half-way inserted pin against something hard . About the wire "pins": The Army model has only one pin I think. This picture is taken from the G&G guide on Arnies. Anyone knows if a version 7 cylinder head from a M14 fits? It looks nearly the same as on the Army R85... Would be great if someone could try if it fits? It's easy to replace the cylinder head...

Don't worry, just stay cool, don't use too much force . It's sometimes tricky to put the two parts together so they will slide into place - it has to go easy, if it doesn't then try to put the together again. Don't forget to place the wires to the front and use the small metal ring near the magazine chamber to hold the wires in place.
