There are x 2 of the above, one made in Korea and the other made in USA, This was made by Hostile Creations in Korea, then Hostile INC in the USA, the ones in the USA were all called back for modifications as they found there was a problem with the Bolt and the Reg, due to a lot of lazy people a lot of these were Not sent back for the work to be done, and soon found putting up for sale because they couldn`t get them to fire correctly, I know because I bought one of these without knowing about the situation, then I found Korea guns ( Hostile Creations ) Don`t want anything to do with guns once sold, then found that Hostile Inc in the USA No longer want anything to do with their own guns once sold,
Great back up service don`t you think.. NOT !!!
If you try to get an address ... You wont !! Sure you can sign in to their web page but that`s as far as you get, leave a message ? but you wont get an answer.
I don`t know how you can tell which one is which other than the Boards are different
all I can say is if your happy with the one you`ve got, fire it until it dies because your on your own on this one.
I will say My gun fires quite happily at 465 fps Ooops !! and until I can get any change with the bolt and reg I can`t use it . I do like the feel of the gun and it sits nicely in the hands, I wont be buying any more guns overseas any more. Lesson learned.
