Thanks for the video! Any reason why the number of velocity turns is different for FSC and TCP? Thought they were the same
-
Curious, how long can you have a punchered co2 in the pistol? I like the reviews I've seen, except for the twist to engage especially under stress. Thanks in advance.

Can You make a video of this First Strike with Music Intro like You did with the Grimburg? :)
-
Not to get too far off topic but I thought I heard somebody say that you were going to make some sort of plug for the VKS where the hopper cover goes to hold in the one detent that is missing?
-
Can you do a tutorial on how to replace the Orings please? Id have thought thats the most complicated thing to do and yet you havent included it in this video? thanks
-
What are the pros and cons of the 8" vs 5" barrel? Is the 8" more powerful and accurate? Also, will it use more CO2 per shot? Thanks!
-
What would you suggest for the fps adjustment screw? How many turns/rotations do you recommend? Thanks so much!
