Aa r85(l85a1)

[Stuart Heath]

Good evening all,

I have an AA R85(L85A1). On single shot, it was cocking with one squeeze of the trigger, then discharging two BBs on the next squeeze. This pattern happened almost every time. Intermittently it would also not fire at all, or fire a small burst of auto fire. Auto fire worked fine(although I doubt at full capacity!) Subsequently, I have taken it apart and identified a broken tappet plate and stripped piston.

Therefore, due to the R85 having a non standard piston I understand that my best option(which should fix my original issue and replace the broken parts) would be to fit a standard piston and sector gear. I also believe that it is not ideal to change just one gear, but do the set?

Please can I have some advise on my best options for the below parts which I believe I need, feel free to let me know if you think there is anything else I will need.

10mm piston spacer

Gear set -??

Piston ??

Piston head(if required) ??

Tappet plate ?

Any help is very much appreciated!

Stu.
