I bought my MCX as a 5.56 pistol. Then I bought the 9" and 6.75" 300 BLK barrels and the suppressor forend. I don't have any other forends and would likely by the Mid-west industries or the Virtus forends.
A 9" factory MCX 5.56 barrel would be nice to line everything up with the same forend. I bought the Rattler as a SBR so I won't bother converting the MCX to a SBR. In VT we can have a loaded handgun in a vehicle (still) but not a loaded long gun. I have carried a 300 BLK for my patrol rifle since 2012. It is a Colt lower with an AAC 9" upper. I run a AAC SDN6 on it. It has been a great rifle and I really like the cartridge. I bought the MCX to convert to SBR for a new patrol rifle, but with all the changes and lack of information I have delayed that. I have spoken with my Chief and he is on board with the Department purchasing Sig Virtus SBR 300 BLK with a 9" barrel for our patrol rifles. I have had a hard time finding the beast in the LE channels. It seems they like the keep the serial numbers or part numbers separate. If I hear anything about the 9" 5.56 barrel I will let you know. Thanks, Mike |

Sounds great. My department only allows 5.56. We do use a really good round though. Winchester 5.56 64 grain tactical bonded. Part #RA556B.

That is a great round for the caliber. I had switch to their 64 gr Ranger round about 2 years before I switch to the 300 blk. I have learned to enjoy the sound/concussion/gas/impulse or whatever term works. There is a big difference and to me the 300 BLK is a joy to shoot. Fortunately my current PD and last PD allow reasonable alternatives. I can understand some concerns about the expense difference for training in volume, but there is minimal difference for duty ammunition. That is one reason to take a look at the MCX. We are considering an extra barrel in 5.56 for higher volume training and in the event we can run sims in the guns.
I need to find or make some time to use the MCX more to experience the difference in the gas system...maybe the 5.56 is not so bad suppressed. I have not shot the 5.56 barrel yet. |

Has anyone seen the rattler sbr in the wild? If not, does anyone know if and when they might be released to the public? My LGS has the pistol version, but swears the sbr version is coming soon and I would like to wait for the sbr if it is not vaporware. Thanks.

Has anyone had any experience with the following combo?
- 6.75" 300BO barrel - Sandman "S" can - Both supersonic and subsonic ammo The suppressor does not have a min length requirement, but I'm not sure how the 1/5 twist will handle a variety of bullet weights and a suppressor. Thanks |

I have experience with that. Works great. Smaller and significantly quieter than my mp5. Zero at 1” high at 25yds and you’ll get a useful maximum point blank zero. Don’t really have to start holdovers until 200yds. Make sure to set for to more gas setting when shooting subs. Supers will run in either setting but you can avoid gas to the face if you switch back and forth with appropriate ammo.

Good to know. Once the can is released from jail, I'll be on the hunt for a 6.75" barrel and probably sell the 9" currently on there. This may be a dumb question - can the upper alone work on a standard AR lower, or does the M4 adapter need to be on there to match the height of the Virtus upper?

The adapter also give a you the ability to use MCX stocks. |

Coregon,
Heard from an MCX owner that he had his barrel locking collar break after 3 barrel swaps and says this is definitely a weak point for the MCX. Could you give some insight on this? Thank you. |

Not knowing the exact circumstance, i'd bet $100 that he didn't have his barrel fully seated before trying to torque/tighten. We've seen it happen before - I definitely wouldn't call it a "weak point". I've swapped barrels hundred's/thousand's of times across the ~10 MCX rifles I own. Never had an issue with the barrel collar showing wear, breaking, weakening, etc. |

According to this thread, the MCX and MCX Virtus uses 6061 and the Rattler upper uses 7075.
Why would Sig use a weaker aluminum when they claim this is the toughest rifle around and can go 20k rounds without a part breakage? Maybe Coregon can give us some input on this? http://sigtalk.com/sig-sauer-rifles/279457-now-very-interested-why-mcx-virtus-6061-alloy.html#/topics/279457 |

6061 has better long term corrosion resistance, and every wear part is a replaceable steel insert anyway.

Problem is that the area of the AR lower that the buffer tube screws into is slightly wider than the slot the collapsible brace rails ride in.

I received my MCX Rattler SBR yesterday. It came with the magpul grip and fixed stock. The stock is smaller than the regular MCX stock. The Rattler balances very well. The stock works well with my external armor. I mounted a Griffin Armament Alpha on it. I need to file the Form 4 and hit the range.
Here is a pic of the Rattler. As far as the 9" 5.56 barrels go I asked and was told they are not available. I believe they found a stock number, but nothing on hand. Still trying to get three LE guns (MCX Virtus FDE 9" SBR). I think we are going to look at the IOP list to pick them up. I cannot believe they still have not been certified. It has been over a year I have asked for them from the area distributor (I was initially looking for the grey Virtus) Here she is
