The MC6-SD Pistol is the end result of a lengthy R&D program in partnership with 3 large Law Enforcement Agencies.  The goal was to develop a weapon system that was chambered in .300 Black Out, highly concealable, sub MOA capable, utterly reliable with super sonic/subsonic ammunition and able to facilitate the use of a suppressor with no change in performance.  Oh, and the barrel length had to be less than 6.5".

Utilizing a Law Tactical folder and available as a Short Barreled Rifle (SBR) or as a pistol featuring the Gear head Works MOD 1 Tail hook.  This highly versatile platform is 15" long with the brace/stock folded and easily fits into a Vertx EDC Transit Sling Bag which is shipped with the gun.

If your looking for the smallest most compact rifle caliber platform on the market then look no further than the MC6-SD.  Available in a wide variety of colors/patterns.  If you have any questions please give Jonathan a call at 601-482-3610.  He can handle your questions as well as special orders.

Availability

My money... shut up and take it.

I am sure we can make that happen.  There are a few demo guns in the Meridian armory.

It is available with a stock or PDW style brace/stock.  We have shipped them in all configurations.  However, we have found that 90% of end users want the pistol variant with the Gearhead Tailhook brace.  Agencies tend to buy them with side folding adjustable stocks.  Commercial customers want the side folding pistol.  SIG makes a great gun in the MCX.  I have one.  Nothing wrong with it.  Only issue is that it has virtually no interchangeable replacement parts that are compatible with the AR.  This means if I want back up parts I have to source them from SIG directly.

We wanted a gun that didn't anchor the end user to our proprietary parts in the event of a failure or breakage.  The entire operating system of this little gun can be replaced or changed using parts sourced off the internet and access to a few armorer tools if need be.

Correct.  The hand guard interfaces with the MC6 upper only.  It will not work with someone else's upper receiver.

It would be nice if that upper was available by itself.

They will be soon.

5" along the top rail

The only suppressors we have run into any issue with are the SIG QD cans.  They have a large OD and the ratchet on them will slightly rub the inside of the SD rail when taking them on and off.  We haven't had any complaints about using SF cans on them.  The guns were designed around Griffin Armament Taper Mount cans and their lack of a ratchet system.  The SD rail has an "inner diameter" of 1.70" if that helps.

We will be selling complete uppers soon.  No parts kits though until demand slows or production catches up.

That we can do.  Whenever we get caught up you will be able to buy it with whatever muzzle device you want properly installed on it.

5.5 lbs.  The LAW folder adds almost a full pound to the gun.  It will cycle some of the higher velocity subs without a can, but we recommend a suppressor when shooting subs for optimal reliability.

Barrel has a twist rate of 1/7.

The pistol variant uses an extended length pistol tube.  The SBR variant uses a carbine buffer tube.

Sorry, but no.  The rail is part of our integral billet upper so it will only work on our guns.  We use a shielded barrel nut system not found on normal forged uppers.

Thanks!

1.  Currently we are only making them in the 5" version and we can't make those fast enough.

2.  You can.

3.  That is correct.  Unexpected demand is taxing production capabilities so for the foreseeable future we will only be doing complete guns.  We will offer just uppers at some point.
