    For the people talking about CFW45 bolt, tom sent it to me for testing before I got divorced/sold my mac10. It was heavy as fuck. Like crazy heavy. I think most people would pick it up and not care about the super slow speed, forget the astronomic cost to have it made now.

    3lb bolt makes it a 12lb gun. I think Sam and Tom had a solution for this if it can make it to production at some point.

    I’m really sorry to hear that. And MedPhys?

    It was my understanding that the .45 bolt was almost 4 1/2 lbs.

    I thought Tom was going to use a shortened 45 bolt with a longer stroke like the A bolt for the M10/45. You really donít need to get the gun to shoot at the grease gun rate. A shorter bolt would use less tungsten and keep the cost down.

    Tom and I talked about shortening the M10 bolt a couple of times. The ejector rod, in the bolt forward position, is very close to the end of the bolt. If the bolt is shortened then a spring loaded support for the ejector rod, would collapse into the bolt when the bolt hits the buffer. He thought that the added complexity of such a spring loaded ejector rod support would be added complications.

    What about a standard bolt with tungsten weights inserted? I wonder what kind of rate of fire reduction you could get?

    Tungsten is sooo expensive. Since only added weight may do the trick, engine builders would use Mallory Heavy Metal. It's cheaper.

    I don't know if the CFW-A bolts will ever be made again, but I'm selling mine now, so if you want one, here's an opportunity. If interested, send me a private message.

    The little tungsten weights for pinewood derby are quite affordable. I believe that is how early prototypes were made.

    I read about that in the news, closed the place down after that. Pic from the article.

    I don't have a mac 10 but Im wondering if this idea would make more sense. It looks like it got put aside and forgotten. The concept in 45ACP would probably beat a $2000 dollar brick of tungsten.

    Adding friction to an original firearm mechanism is problematic at best. To add a roller delayed blowback system, either a forward magwell well would need to be integrated or lots of custom very precise hardened parts would need to be made. I have found that custom parts are 10 to twenty times more expensive than OTS parts. The precision and hardening required for the roller delayed system would drive costs even higher. It seems to me that increasing the mass, increasing the stroke, and reducing the spring rate to just enough to strip, chamber, and fire the round would be best to reduce the ROF.

    Some data.

    Tried 3 variations of bolts today. Used to own the original CFW tungsten cube pinned to a new CNC steel bolt but that wasn’t available this time. Same upper, 115grn Blazer unsuppressed.


    Stock
    Gen 2
    Gen 2A -latest revision




    Stock bolt, minimum 4 round burst



    Full size CFW, single shots easily- Feels nearly identical to a stock Uzi, a bit choppy but not bad. Manageable.



    Gen 2A CFW, 2-3 shots minimum, but that’s by design with tuning to keep as fast as possible. The smoothest possible on an M11. Easy aim & hold on target. Cut 4 coils off a stock spring. Personal favorite as smooth shooting and still fully controllable. This bolt can go much slower, but not much faster.

    This is my Son and I shooting our M11/9 with a gen 1 CF-W bolt. This is an early bolt that does not have The CF-W 9MM etched on it. The gun had a top cocking 10 inch barreled upper. Shoots like my Sten MKII only much more comfortable.

    That’s a production full size cfw gen 2 bolt boomer. The first 200 hundred were not engraved. The gen 1 bolts were hybrid steel and tungsten made by coffeefreak

    I thought the original hybrid bolts were prototypes. The gen 1 were full size M11/9 full W bolts. Then it gets a little confusing because there were two versions of M11/380 size bolts.

    Are you sure about that 200 made number for the initial production run? I was under the distinct impression that the first batch of the actual production, tungsten-steel alloy, non-engraved, 32 oz. bolts bolts with separate firing pins was 100 units, which sold out in about six months. For the second batch of 100 units of 32 oz. bolts with separate firing pins, the bolts were engraved with the "CF-W" marking, but took around two and a half years to finally sell out; and that was after VegasSMG had turned over sales to Lage and Practical Solutions. In other words, there were 200 production, 32 oz. bolts with separate firing pins made.
    MHO, YMMV, etc.

    ETA: And I'm pretty sure the 380 -sized (approx. 25 oz.) tungsten alloy bolt batches have been considerably smaller - 50 or 25 units each.
