My Midwest Industries handguard came in yesterday, went ahead and swapped things around on my MCX. Still need to pull my Surefire flash hider from my Six8 PDW and migrate it over to my MCX 300BLK for suppressor use, sadly wasn't able to find one of the Legacy flash hiders to just slap onto it but oh well.
 It compared to the Six8 PDW collapsed. Will be a tad longer, once it gets the Surefire flash hider but still should fit in my laptop bag easy.

Seems in my quest to get a low back pressure can, I found one that has too little. My 6.75" 300BLK barrel with the gas setting on suppressed with S&B 200 grain subs, was able to cycle but locks only half open on empty with 20 round lancer 300BLK mags. I've known I needed a better SBR can for a bit but guess this will end up rushing the matter.

Also, just curious -- are you by chance running a POF roller cam pin in this setup? It's brand new, actually just tore it apart again and found the op rod is ridiculously tight in it. I had to push the op rod/piston out with a punch and then tap it back in even. PMed @JohnnyUtah427 as I noticed he was having a similar issue in another thread and he gave me some guidance on what to do. Will get a few hundred rounds of 300blk through it and pull it apart a couple more times before I make any rash decisions or over-reactions. Update: It's locking back fully on last, with subs on the + setting. Seems the take down/scrub of the piston and gasblock freed it up. |

IF it takes off all I need is a barrel But if Sig cant even keep up with 5.56 and 300BLK orders on the Virtus I would just take a wait and see approach as well. But that brings us back to the gun industry for the last 10 or 15 years.. Sell a multi cal gun... take forever to produce caliber conversions lol |

IF it takes off all I need is a barrel Both of those excellent rounds cover a slightly different function, so I doubt either will be going away IMHO. The 6.5 Grendel offers better performance for hunting, in large part due to the heavier projectiles it uses. The 6mm ARC has excellent long range ballistics but is limited due to the lighter projectiles. That being said... I'd love it if Sig Sauer added the 6mm ARC to the list of available calibers in the Virtus line. |

Took my 6.75" to the range on Saturday and shot some 110 American Gunner Hornady and Remington 120 Open tips. Found the Remington rounds did great, got a solid group at 100 yards even but the 110 American Gunners had grouping issues, including numerous fliers.
Decided to look into my can and found what might be some baffle hits.  I picked up some more of the Remington 120 grain rounds today and some 110 Hornady VMAX to experiment with but the 110 will be attempted without the can first to see if they work. |

The baffle damage looked pretty damn close to what I'm seeing in my 7.62 can here. It's not titanium, Surefire FA762K. Work is keeping me busy and I'm damn low on 300blk ammo. Will be getting my can/barrel checked with an alignment rod first before doing any further shooting with it. |

It's a priority to get this taken care of as the MCX was intended to be my go to travel/defense setup and I have a trip to CO coming that I want this to come along for. I'm hoping to have more information by this Saturday, I'm hoping it's something as simple as my mount being slightly out of spec or something. This is a new mount that I've personally never used before as the shop damaged the previous mount design I preferred. The joys of owning abandoned/antiquated silencers.... |

Interested to see what your investigation turns up @Zerlak - keep us posted @coregon Was able to take it in to a gunsmith to have a look over of it. He confirmed that the strikes are baffle hits and mentioned he saw some skipping on other baffles closer to the barrel. He took an alignment rod to it and it was not centered completely, seemed to favor a side. The flash hider was mounted using the provided Sig tapered adapter, Surefire provided chamfered spacer and 3 timing rings. The Surefire Flash Hider is the legacy FH762K05 can be found here. It's a legacy can, so using whatever I can get my hands on. I had the smith take off the timing rings and just mount it with the chamfered spacer to tapered adapter, was still favoring a side of the can, based on which of the four teeth that the silencer was mounted to. I had him pull the chamfered spacer off and attach the flash hider directly to the barrel, with the tapered adapter, was still having the offset issue appear. I'm not sure what item is causing the issue, at this point. The mount could be messed up, despite being from the wrapper new for this barrel or my can is screwed up/bent from the factory and never noticed it as I was using it with a 6.8 caliber weapon that had plenty of clearance to use it. Will more than likely be calling Surefire and seeing if they can take a look at the flash hider, see if they can determine it to be within spec. |

However, the Lage RH 5* folding K stock may work without the FA. It might be a tight fit with the brass deflector though. Two photoshopped images, appear to be to scale, mind the ruggedness though as I did them in a few minutes.

Has anyone tried running blanks with a blank fire adapter?Sig told me “it’s an expensive gun, use your best judgment”. A wholly non committal answer from someone I’m not sure understands the question. I can’t see any downsides besides needing to clean the daylights out of it afterwords. I can’t imagine the mil side of Sig would tell the military to not use blanks.
