    You have a manufacturer license? How much does that thing way? Is it 5.56? What are you charging?

    This one is chambered in .308 and we hope to start on a .338 version soon.

    We are actually in the R&D phase - this client was a contributor to our project so he did not buy the rifle, it was a gift.

    When all is said and done it will be a liquid cooled rig.

    It weighs about as much as a Barret M107.

    Why would u need something liquid cooled in a semi auto? Very cool project though.

    I'm not sure I understand the question, keeping a barrel cool on any platform is a benefit.

    Scientific Answer: As little as 3 shots on mid to large caliber rifles can begin to have negative consequences.

    Our Answer: Because we can.

    A bunch of industry vendors have graced their break rooms for the employees with our stuff from what I've been told. haha (no seriously, that is awesome, they could put us as a motivational poster in the crapper and I would be flattered)

    As a side note, this system can be fired in both single shot and semi-auto mode. It utilizes an adjustable JP gas block and future versions will have a small hole drilled out in the chassis for which an extended control knob will be located.

    The user will be able to adjust the gas on the fly externally with nothing more than their fingers.

    This is an older snapshot from our CAD software when the original idea was to simply use a hex key from the outside. we have since decided to make it more of a "knob" as mentioned for tool-less operation.

    Well I cannot take credit for the actual machining portion.

    I am simply the idea maker, the guy bringing it to life in CAD type software, and ultimately the tester and finisher.

    All the raw work is handled by a machine shop we partner with.

    Edit: I remember first time I took it to the range. I put my range box (quite heavy) behind the stock on the wooden bench. Tied a string to the trigger. Stood behind the range box (like a barrier), one palm on it - preparing to put forward weight on it - and then pulling the string with my free hand.

    Thankfully all I felt was a light thud. After three more light thuds I ditched the overly paranoid act and sat down and started having fun. haha

    I understand wanting to do semi and single. But unless that bolt locks during single it seems a little pointless to me. It's not helping at all. Was I mistaken when I saw the bolt jump back during single shooting? And what sort of things are you thinking about doing to combat that?

    The BCG does not move backwards when single shot operation is currently being used. Just like a bolt action (short of pulling up and back in most cases) the BCG must be manually pulled back to extract the spent cartridge and load in a fresh one.

    While not the same as an actual bolt action rifle, the advantages in a system like this is when the shot is fired, you eliminate movement that would normally occur as the BCG extracts the round just ignited and loads a new one. All in a blink of an eye.

    Once again, it does not mimic a traditional bolt action performance wise, but there is a good spike in stability when shooting in this mode of operation.

    And it also makes brass collection easier. haha!

    Pay very close attention to the rotating bolt and the gas operation.
    With the gas turned off, there is no movement, as the bolt is rotated and locked into place. It's the gas, forcing the carrier rearward, engaging the cam pin, and thus unlocking the bolt to disengage it.

    [ame]http://www.youtube.com/watch?v=5oHx6qdteFY[/ame]

    The only reason it can function in single shot this way is because the T-handle on the top and/or the external charging handle attached to the bolt carrier replace the need for the gas, making it manually operated.
