    Thanks guys for the input on features, keep them coming. I'm down with AA sights- have them on my 34 upper and like them a lot. A must have for trap shooting! Definitely will have some mounting method, and some rails for other options.

    The design work continues, but the delay mechanism is promising- if you guys don't mind a slower ROF and less recoil?

    With 12 ga I think slower is definitely better. I like the ROF on the AA12. Any thoughts on whether that recoil system could or should be implemented in some form on a MAC? There's a great video out there of fpsrussia shooting it one handed showing how controllable it is.

    The AA12 mechanism is too large for the Mac. If it could be shrunk down, perhaps- using a stock mounted buffer. Taking a different approach for now.

    Something like the MK 19 rate of fire would probably be great for this.
    Nice slow and steady thump, thump, thump, 40 to 60 rounds a minute. sounds slow but makes it really easy to control.

    Speed it up a bit but keep it slow enough to keep muzzle climb on target while the gun is still running .

    Oh and a mount under the barrel for a shot gun! J/K LOL

    Maybe a laser engraved unicorn next to the Mfg logo ??
    Hell call it unicorn 12 or The McUnicorn......

    You can pull a trigger on any pump or semi 12 gauge faster than 60 rounds per minute. Makes the entire endeavor pointless.

    While I totally see the appeal of the slow ROF I have to agree with IR on this.. maybe 240+ or so (at least) would be ideal- we'll see in testing. I don't know to what degree we can dictate that at this point but it does need to meet a minimal threshold which I think most shooters expect. We'll see to what degree it may be adjustable.

    Close up- bolt clearance needs a little more bottom.

    I wouldn't say no chance! As I've said one miracle at a time. My hope is if we can get the 9/11 done it will be a much smaller feat to adapt it for the other Macs.. though given the current design it's not like resizing an open bolt- it may not be feasible for shorter frames. If it is logistically and financially feasible I assure you I will do my best.
