  3. Sticky Thread Use the SEARCH feature!

    Not to hinder discussions, but a good percentage of post are asking questions that have been covered several times before. I am just as lazy as the next guy so I get that it seems easier to post a question than to search for an answer, however using the search button will give you hours of reading...

  4. Max10/45 - won't run. Short stroke or won't fully chamber round.

    I started with a Texas mac10/9mm with the garand style safety. I bought a 2nd hand gen1 max10/45 that turned out to have a 9mm bolt. Jackie hooked me up with a 45 bolt (reused the weight) and a forearm. Also bought the mag catch to use greasegun mags. It doesn't want to run. It short strokes...

  6. 7.62x 25 / CF-W / Max11sk

    I used to run 7.62 x 25 in my max-11. I was thinking about whether I could run this conversion with a max11sk & CF-W bolt configuration. Does anyone know if the max-11 & max-11sk barrels are interchangeable? They seem to be have the same inside length by eyeballing them. Would this beat the piss...

  8. Are MPA's Fullsize and Velocity's Vmac9 upper interchangeable?

    I'm fiddling around with a design that calls for a Velocity Vmac9 upper. Can I substitute an MPA Fullsize 9mm upper or have the two manufactures deviated from the Mac11/9 spec that they're no longer able to be interchanged?

  9. How does the CFW bolt work? Is it just heavy or also springs involved?

    Since not CFW 45 bolt appears to be coming, I知 eying tungsten, my existing Lage bolts, and wondering if it could replicated with just replacing several strips of steel with tungsten. After the weight is added do the springs need to be tweaked? As a non-engineer, I知 trying to understand the...

  14. Which Lage 11/15 Upper, Internal or AR Recoil Mechanism?

    I hate the thought of drilling a hole in the rear of my incoming 11/9 for the AR style mechanism. How good is the upper with the internal recoil mechanism? And will these take the heavy bolt to slow rate of fire? Thoughts from owners?

  16. Forward grip for stock upper on M10/9 and viper

    Is there a forward grip out there that goes on a stock PS M10/9 but allows the use of a gemtech viper and locking collar? After shooting my MP5k-PDW for a bit, I've decided to let go of my purist streak when it comes to my MAC. Dark day.

  18. Grey Ghost vs Standard PS Side Cocking Upper

  20. Trying Out the CF-W "A" Bolt in a Couple of Different Uppers, 5.25" & 11.5" Barrels

    Hello MAC community members! I realize that a major appeal of the MAC type submachine guns is their overall compact size. For me, the appeal was simply the relatively low cost and after acquiring them, one of my first configuration changes was to mount a longer barrel. So I was not an early...

  23. Using the versatile CF-W A bolt in the M11/9 .380 conversion.

    I had good results using the A Bolt in the M11/9 .380 caliber but I was using one of Tom's "wonder" springs (modified) and I wanted to try the "orange" spring he is supplying because it is a known quantity and readily available. I had solved most of the issues I had experienced with the .380 setup...
