    I cannot find the threads or my links to various web sites for MAC parts and conversion kits, like uppers for the M10/9... Could we please get a tacked thread listing the various places to find MAC stuff? :D

  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...

  1. Bent the first flat

    I've had a MAC addiction since around 1990 when I shot my first open bolt 45acp semi that a buddy owned. In 2000 I bought my first F/A MAC. It was a 45acp Fat Mac. This was the only machine gun that I'd ever buy because the prices were just insane! ($1600 with a can) That last lie didn't...

  2. mac 11 wont accept new firing pin

    bought a Cobray used and after 20 rounds the firing pin broke. So I ordered a new one from Cobray and now the pin will not fit in the upper correctly. I have it orientated correctly but it catches on a slanted piece of metal in the front of the slot where the pin sits. If someone could show me a...

  4. Carlson Comps Inc GAS/BRASS KICKER

    After much time and testing, I have some feedback on my prototype(s) GASS/BRASS KICKER. The units will deflect gas and brass from the ejection port of the M11/9, MAX-11 9mm SMG both suppressed and unsuppressed. This uint should prove beneficial to lefty shooters. The GAS/BRASS KICKER is still...

  5. CFW - 9mmA - First range report. Mixed but optimistic

    I took the M11a1 out with the new bolt yesterday. I swapped out the 380 barrel in my original upper with a 9mm barrel. I tried a variety of ammo from fairly light stuff to hot subgun ammo. When it ran it was a nice small full auto package. The issue I consistently had (maybe every 2-10 rounds)...

    So i upgraded to the max11 mk2 and max31 mk2. My m11/9 cam with a Lage max 11 with a tri lug barrel with the max 11 standard bolt. I added the external gas block, the polymer k grip, Side accessory rails, and picked up a new tactical bolt (that has never been used). I also have the max11-22. ...

  10. Custom M10 safety lever

    Took a few simple measurements, and grabbed some tools. I started with a piece of 3/8" plate. It's slightly thicker than the factory safety nub, figured it would give me a little "wiggle room" and it's what I had on hand that was close. I traced a rough sketch on the steel and started cutting. I...

  12. M11/9 Sometimes shoots S/A

    My m11 sometimes shoots semi-auto when selector is set to smg. It happened when I let my buddy shoot it a couple weeks ago, but he's a lil guy and not really a gun enthusiast so I figured he somehow caused it. But today it happened to me. Both times it did it were with stock upper.

  16. MPA railed 11/9 uppers out of spec?

    So I I didn't check before cutting it down for my m11a1 but it appears to be out of spec now. I clamped it on the trunnion and used a sawzall to cut the back off, so I don't see that that would be likely to make it go out of specs. The bolt is very hard to slide with both my oem and CF-Wa bolt,...

    Just finished a project I thought you guys might enjoy. Put a Kinetic Development ACR/SCAR stock on my M11A1 MAX31. Took a fair amount of work with a belt disc sander, as well as some acraglass gel, but am very happy how it turned out.
