Thanks for the pics. I'm torn if I will want to do 9inch and have muzzle past handguard if I want to shoot unsuppressed and have super short gun or getting 6inch barrel for maximum compactness. I have 762TiQD so it's a lititle more length added. Hmmm. Any input on different setups?

I hope Sig will reintroduce the 9" 5.56 barrel. Other companies are using even shorter barrels with no issues. I do like the 11.5" but I also would like the 9" to go with the PDW handguard and keep the overall weapon as short as possible.

Will MCXs with shorter barrels be available up in Canada?
It's already a restricted firearm, might as well get it as an SBR.

Any chance you can throw a lower on the long barrel one so I can see the whole deal? |

If you have a chance could you possibly do a couple pictures of the 9" barrel put together with the Suppressors. I just sent my Form 1 in and I'm trying to decide on which suppressor to go with to complete my rifle. Thank you in advance

Coregon, you should get Sig to be a sponsor on Gunstruction and get the MCX on there.
It could save you some time :) And also, it would be cool. |

My carbine length fat handguard is "Out for Delivery" right now, post a pic when I get it setup. I have had to live vicariously though posts like this for the last 13 months while it was on order.
my 6.75" 300 barrel is on the same order , but not shipped yet... someday... |

Is there a shorter upper so the 6.75" could clear a FH or brake? Or is it only designed to be ran suppressed?
I am seriously getting one of these as soon as I find one. |

My 6.75" barrel got delivered last week when I was away on vacation, and the carbine wide hand guard should be delivered tomorrow. I think at this point, all Sig still has on back order for me is the 11.5" 556 barrel, and the not yet released 762x39 kit. I have shot my MCX with the 9" barrel, Surefire 300sps, and "rifle" length hand guard, and it is very, very, very quiet with subs. |

All I can do at the moment is live vicariously and request more photographs, let me know when/if they already have gotten annoying.
How about LVAW (any suppressor) with all three handguard lengths for comparison? Also, semi-related, is there any more news on AR lower adapters? ~Augee |

My understanding, please correct me if wrong, is that the actual LVAW uses the AR-15 adapter on full auto M4A1 lowers that were already in SOCOM inventory. Since it was classified as a weapon accessory, it was easier for them to procure than a full on new weapon system. You may be thinking of the recent USSOCOM PDW solicitation, which is intended to use an M4A1 lower. While we're all assuming that an LVAW-like weapon will be submitted for the SOCOM PDW, I don't think that this has been firmly confirmed, though it seems like a no-brainer with some alterations to meet the fairly optimistic requirements of the PDW. That being said, while my personal guess would be that the PDW solicitation is intended as a way to "backdoor" something like the LVAW into wider service, which is something that SOF has been looking for for a while, with weapons such as the CQBR, HK416, MP7A1, etc. all being "interim" solutions, by "definition," the PDW and LVAW would be two different weapon systems for two different purposes. ~Augee |

Coregon, do you recommend a QD suppressor over a direct thread? Im on the fence on what suppressor to get. While i love the QD, the thread on has more baffles which should be quieter? Or am i just getting too technical about it? I want the best suppressor to size ratio, itll be going on the MCX with the skeletonized folding stock.

Thanks for the info. I would think that for a rifle designed to be used suppressed at all times integrally suppressing it would make the most sense. I also seem to recall that at one time there was a version of the MCX that was integrally suppressed. Are you able to provide any insight as to why they did not go the integral route and if I imagined an integral version of the MCX?
