Product Description
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. Machined out of 6082 T6 aluminium and supplied with a hex-head M3 43mm screw, this allows the use of standard pistons within the R85. Please be aware though, you NEED to replace the sector gear with a standard TM type gear to deal with the lesser tooth count. 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! Please Note: The piston shown in the picture is for illustration only and is NOT included. They are available seperately. And now the technical bit, for those of you who care... "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!
