    I got the idea on trigger weight from Mike Semaan and his channel.
    It's simply a matter of making the spring stiffer.
    His instructions don't need to be followed to the letter. Use as a general guide. I literally had a spring in my shop that worked, but plenty of links to springs. Mine is actually heavier at 6.5lbs.

    Here's a link to my shop video testing the pull with a continuous force gauge so that you can see the full pull:

    I'm impressed by the guys who get the FRT to work with the CMMG 22LR kits.

    I have heard varying comments regarding the FRT spring kinking issue
    There are a few videos that show replacing the spring after creating a recess for the spring to
    sit in so the spring wont kink.

    Rare Breed claims that users take the FRT15 when its not in the gun and fiddle with
    it to understand it better and out of the gun, you can move it more than it would when its inside the gun
    and ruin the spring
    I am justy repeating, dont have an informed opinion....but springs are
    cheap so I ordered some.
    Rare Breed claims they have got 20,000 rounds with no issues

    A guy on youtube said that the main culprit of the malfunction is the clearance inside the bolt carrier.

    Post removed- I now believe BCG is not the issue but the design as Jack007 states below

    The problem is the DESIGN and not the specs on your BCG. Period. Anything else is pure BS. Most commenters are not gunsmiths much less machinists. A first year machine shop apprentice could diagnose this in under five minutes. You don't use a linear spring where arced vectors are involved.
    The various fixes, including mine, are simply workarounds since truly "fixing" the problem, would involve a complete redesign. Rare Breed's official line that it only should move 20% etc...is completely disingenuous and devoid of the reality of basic physics. The extreme forces involved will move that bar forward via inertia further than 20% regardless of the bolt carrier dimensions. My own carrier was a stock Colt M16 and kinked my spring before I even fired the gun just by dry cycling. Other moronic statements floated by Rare Breed and some of their shills included that squeezing the trigger too hard, which can freeze the bolt in rear battery, was causing the kinking. Amazing, when you consider that at that point in the cycle the carrier is nowhere NEAR the lever.
    Having said all that, it's a great concept and once you address it's issues, it's worth the money. At least for me!

    On a positive note, I finally had time to test my ATI Scmeisser 60rd mags. After never having had a single malfunction with any of my SureFire 60 mags I figured the bar was a bit high.
    Ran several mag dumps without a hiccup. So as far as I can see, these mags are good to go. German workmanship strikes again!
    I feel a definite slowing in ROF since increasing the trigger pull to 6.5lbs and the buffer to H3...which is what I wanted.

    Here's a crazy one for the AR experts...

    My friend built one from an 80%. Nothing fancy. Typical 16'' bbl etc. Dropped an FRT in there and it runs beautifully. His 18 y/o is out there squeezing off singles like it's a stock trigger. So naturally I have to pop it open to see which H buffer he's running? H3? H2? Nope. A standard weight! Not even a heavy buffer! I popped it on a scale and sure 'nuff less than 3 oz. WTF? I had him try all mine. H1 to H3. They all ran, but it was HARDER for him to get singles. So he left the standard one in. Go figure?

    Strobo can you determine ROF from a vid?
    I'd love to know what it was before I modded it?
    I THINK it's slower now but...

    I use a free sound recording program called Audacity that member Medphys turned me on to. I play the video and record the audio. Then I look at the spikes in the graph. I delete anything before the first spike and everything after the last clean spike. That gives me the total time. I count the spikes and divide the rounds fired by the time. Multiply that number by 60. That gives me the ROF.

    Fascinating! I've been using Audacity for years. I use it to edit all my MP3s that I get from YT videos etc...
    Never thought of using it for something like this!
    Doesn't surprise me given your track record in the industry. You're def an innovator and think outside the box!
    Thanks for sharing!
