The AA R85 is a stunning and beautifully engineered gun. It has only one major flaw that we have encountered - it uses a non-standard piston. So, if your piston fails, you cannot just reach for a new Systema or suchlike. There was a similar spacer available but it is very hard to get, so we went to a friend of ours in the UK and said "can you make us this?". And he did.

This allows the use of standard pistons within the R85 (or other 19-Tooth Pistons). Please be aware though, you NEED to replace the sector gear with a standard TM type gear to deal with the lesser tooth count or alternatively, modify the existing Sector Gear by removing three teeth. If you don't feel up to that task, we offer an all-in package including the spacer, piston, gear, fitting & collection & return postage. We are nice to you!

And now the technical bit, for those of you who care...

  • Made in the UK
  • 6082 T6 Aluminium
  • Supplied with a Hex-Head M3 43mm screw

"Aluminium alloy 6082 is a medium strength alloy with excellent corrosion resistance. It has the highest strength of the 6000 series alloys. Alloy 6082 is known as a structural alloy. As a relatively new alloy, the higher strength of 6082 has seen it replace 6061 in many applications. The addition of a large amount of manganese controls the grain structure which in turn results in a stronger alloy."

So now you know!

Great part that's solved more than one problem
Review by
I got myself a second-hand R85 that had a stripped piston, so I decided to try to 'mod' my own spacer. This led to the new, 15 tooth sector gear engaging the wrong part of the piston's pick-up tooth, which would've sent the new 14 tooth piston the same way as the original.
This spacer made the piston slightly longer than the original, so it is now engaging perfectly. This is a great piece of kit and I would recommend it to anyone who has an R85.
Had to file the hole of the piston to fit it on, but that takes next to no time to do.
Thanks Airsoft World :)

Excellent but not perfect
Review by
I bought it last week. For its price, it's a bit expensive, but I hadn't the choice
It's very useful if you have got of course the R-85A1, but you have to use a polycarbonate piston, not an aluminium piston, the spacer won't enter in it
