N/A Alpha Proj co2 rifle

NO
these rifles come up in the forums from time to time and the same thing happens.
little or no information is available.
i have been looking again and i don't know why i knew from the start i would come up empty and only to find my old posts.
the one thing that will help is most of the Czech guns were all made the same for the most part.
and i don't believe there is much to replace.
a few Orings and 1 seal.
the piercing cap would use the same Oring as any CO2 gun.
i have a Listone Victor and it is a clone of the Air Arms badged pistol and mine is CO2
yours was just the rifle of the pistol and i would think the guts are the same.
i would think the TAU 7 has the same guts.
do you have the owner manual because all Czech guns have a parts diagram and parts listing, and the Oring sizes are normally listed even the clone has that.
is it leaking and if so from where
i have my Victor diagrams if you want them
