  • Thanks for the video! Any reason why the number of velocity turns is different for FSC and TCP? Thought they were the same
  • @jrhjrh9372
    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.
  • @sweetleaf7751
    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
  • @dandanny7402
    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!
  • @GLOWZOORECORDS
    What would you suggest for the fps adjustment screw? How many turns/rotations do you recommend? Thanks so much!
  • @jft7174

  • @Rice4Life13
    I have the tcp. I’ve done all that mod plus the prv delete with vks spring. I keep mine 2x from max. Hope I don’t break anything.

  • How many juls does your GRIMBURG FSC run at before its shipped?
  • You guys have done and amazing job. would this be able to be shipped to the UK, in a standard box?
  • @whypayforbud
    Does the pepperball and the first strike use the same magazine? And how about the barrel?
