Would anyone know what material and hardness specification Steyr use for the o-rings in the LP10 please?
I've searched through the previous posts on o-rings here but can't find a definitive answer. If I had to guess I say Viton with Shore A hardness of 70 or 75 would do the job but if someone knows the actual Steyr spec it would be good information to have.
Thanks.
