Gross. All that effort and they mold in an A2 pistol grip. I remember asking about that thing at Shot Show over 6 years ago. They had to have made the goofiest product rollout of all time with that one. .22LR pistols, etc and they are just now finally getting around to the actual 5.56mm version. |

The ARX has a lot going for it. Molding an A2 grip was not a good idea though... The price point is excellent on them at $1200. They just need to roll out with short barrels and .300 BLK. |

I'm currently trying to decide between the SBR and the carbine.
I know "technically" accuracy isn't overly affected between these barrel lengths on the 300 blk but does it really play out that way in practice? Thinking 100 yards. 5.56 is another story but I dont care about that here. Other than the tax stamp - what advantage in practicality would the 16" barrel offer? |

Info provided by AAC:
The 300 AAC BLACKOUT (300 BLK) cartridge is highly efficient and outperforms 5.56mm when used in a short barrel rifle and comes very close to the energy of 6.8 SPC but with less powder and resulting blast. The included AAC BLACKOUT flash suppressor eliminates all secondary muzzle flash. Compared to subguns like the MP5-SD, it has more accuracy, more penetration, and 165% the energy at 200 meters. These properties make it ideal for personal security. AMMO COMPARISONS At muzzle: 5.56mm, 9 inch barrel, M855, 2570 fps, 909 fpe. 300 BLK, 9 inch barrel, 110 grain V-MAX, 2150 fps, 1129 fpe (24% better than 5.56mm). 6.8 SPC, 9 inch barrel, SSA 115 SMK, 2173 fps. 1206 fpe (7% better than 300 BLK).

I saw a post on another forum where a member says SIG is going to change back to a user-adjustable gas system due to fouling in the current design.
Anyone heard anything definitive about this? Posted Via AR15.Com Mobile |

1 of the things about the gun is that it is supposed to maintain proper bolt speed suppressed and unsuppressed without fiddling with it. So going backward to a manual system would be a mistake in my book.
Maybe they are just going to add some kind of manual override to it in case the gun is very dirty or you have some bad ammo. Posted Via AR15.Com Mobile |

Posted Via AR15.Com Mobile http://sigtalk.com/sig-sauer-rifles/34043-sig-mcx-4.html THX! Posted Via AR15.Com Mobile I wonder if the 7.62x39 version needs a multiple position system. It wasn't designed with supersonic/subsonic compatibility in mind like the 300BLK and tends to run dirtier due to the lower end ammo. Perhaps it is just the 7.62x39 that will have a different gas selector. |

I wonder when the upper kits will be available for us SBR owners.

They were estimating about 2 months for the time frame on the lower "extension". Didn't ask about selling the upper separate. I was more interested in seeing if I could quickly toss it one of my SBR lowers rather than wait for my stamp to come back. |

The member on SIGTalk has posted again. Apparently no changes coming to the gas system at this time.

Quick update, ran about 300 rounds through my 9" in 5.56mm this weekend. 55gr PMC mostly suppressed. Didn't skip a beat. Ejection pattern didn't seem to change with/without the can. Despite having a sub-10 inch barrel, it was remarkably quiet with the suppressor compared to my other 10" 5.56mm guns(SCAR/AR/P556).

Nothing really glaring at this point. Only thing I could see was a couple contact points on the upper under the charging handle latch from contact with the charging handle itself. Completely cosmetic(and you can't even see it unless you're pulling back on the latch). The steel channel inserts seem to be doing their thing. Should also note that whatever lubrication there was on it was from the factory. I wiped the carrier and bolt down and lubed it with EWL. The finish has darkened on the carrier/bolt, which has been common with my ARs with FailZero carriers. Will do a more extensive teardown when I get through the first case. |

What can are you running? I was worried about installing a can with the 9" barrel since AAC doesn't warranty them that short.

Not really warrantied against that short of barrel but did just fine. Long term plan is a Thunderbeast Ultra-5 to use with both .300 and 5.56. |

I know the guys at SIG ate aware of the <10.5"/can issue.
I asked Austin at Griffin about his opinion on using it with my M4SDK and was told there shouldn't be an issue. I still want a 10-11.5" MCX though. |

I've been kinda hoping Barnes would make a lightweight .300 bullet. Subsonic isn't as interesting to me as the terminal ballistics of a good supersonic round are. |

Looks like that round is getting some press from TFB.

Maybe a stupid question, but are the MCXs imported or built here. I would love to buy the pistol version and SBR it.

Wonder how long it will be until they sell the rifle with just the 5.56 barrel?

I may have missed something, but are they (sig) going to offer a telescoping stock on the mcx as they did on the mpx? Never been a fan of side folders. If it is available now, will it work with the milspec lower adapter?

This was posted on SSD this morning
Congratulations to SIG for the Win! I think I know which Unit this is for, but like SSD I'll let SIG make a press release. Just think, HK won't release their "elite" 416, other than as a nearly $3K sporting version, but SIG is/will-be offering the MCX for under $2200 along with SBRs, etc... |
