I also had a screw snap in half with very little torque applied. Damn thing is still stuck in the receiver, haven’t drilled it out yet.

Does ANYONE know of a MI 10.5'' handguard in stock? Or have one they want to offload?

How can I tell if my MCX is a Virtus or Legacy model? Given it's relatively new, I am 99% sure it's a Virtus, but it does not officially have the "Virtus" stamp on the cam path insert. Instead, it's blank, as I think this was a LEO model (it's black vs. FDE/Gray).

Well, well, well. How the turn tables...

Regarding the G latch on these - is it correct that with the latch I can run a standard trigger group? I really want to use my SD3G on my 11.5

So, the [A*F] disapproved my Form 1 for the following reason:
DISAPPROVED - OTHER "MA LTC REQUIRED, REFUND IN PROGRESS" WTF is this? I've done two other Form 1's for other lowers and never sent in anything related to my LTC credentials...... it's not even asked on the application.... Has anyone seen this before? - Cross posting this reply in the FORM 1 thread/forum. |

Ok so technically not Virtus specific but I have a question...
I have three legacy upper receivers and was prepping one for Cerakote when I noticed the feed ramp insert screws appear to be drilled out/tamper resistant thereby rendering it a permanently installed piece. At first I thought the screws were just stripped but a second receiver also has similar screws whereas the third receiver has normal torx-screws. Did I just get unlucky with two of these receivers? Are they supposed to be like this? Attached File Now I get that 99% of users will never need to replace the ramp and normally this wouldn't bother me but my OCD demons are desiring a completely stripped receiver prior to coating. What's also interesting is why Sig would use tamper screws here (if intentional) when every other "detachable" part is removable? Also, does anyone happen to know what size screws are used for the feed ramp insert? They look to be the same as the deflector housing so I'm guessing 4-40x1/4? @coregon |

"A Mk18 is a handgun with a stock"/"10.3 is a 50 yard and in gun" - From SHTF AR Thread |
So, I've found a solution to my "low-profile/LVAW forward assist stripped thread fiasco..."
After reading the FAQ Thread and confirming specs, screw and thread sizes with SIG CS, I began my endeavor. I purchased the PowerCoil UNC4-40 Thread Repair Kit [pictured below]. This kit has everything you need to repair any 4-40 stripped thread. Good buy. Several members had recommended after the fact (and I wish I had listened and not impulse purchased) checking MGW for the screws to avoid purchasing a complete forward assist from SIG. After receiving the new forward assist to have some spare and backup parts if there was something more going on behind the scenes, I took a look at the low-profile/LVAW forward assist I had installed and immediately realized that both the threads and screws were fine... The actual plastic on the LVAW forward assist had split from obvious over-torquing... So, I removed the LVAW forward assist, replaced it with the new standard forward assist, torqued to 10-inch lbs. and we were back in action... Really goes to show you how little you need to work on these small screws. I fault myself for not looking in the FAQ thread before tackling this project to get the torque specs but in the end, lesson learned. I'll hopefully get to order another LVAW forward assist soon as I really enjoyed getting the bulky stock one off. Thanks everyone for the help. |

A few months ago I had a black 11.5 Virtus LE that I stupidly traded for another rifle as I was afraid of the whole "SHTF" and parts availability for the MCX series. I have since sold said rifle, while it was a SOLGW, it was a 16" and overall for my needs it's not what I want. So, I'm back in the market for a 11.5 Virtus in black.
That said, I had a couple questions before buying one that you folks could probably help out with. -Since the MCX has been out, has the 6061 vs 7075 aluminum thing been an issue given the upper is reinforced on the inside? I'm mostly speaking on terms of durability of being used and abused for training and so forth. I assume the lower is also 6061 and obviously trigger pin wear is also on the mind. -Has anyone used the Arisaka ZRC? I noticed with my last MCX that rail shift is a real thing, just pushing on one side would shift it quite a bit. I thought about getting the ZRC but didn't know if that would be enough. I'd like to put something on the top picatinny rail that clamps the handguard to the upper to also prevent shifting. Thanks! |

Just sparking some curiosity...
Been heavily debating selling my Virtus Patrol [Noctis model]... Just because I never shoot her anymore and she's turned into a safe queen/relic. Had her factory cleaned and just got her back from SIG fresh as new... Hold it or not and why? |
