Its been a hell of a year sourcing parts for my build. I got a sig virtus upper and found a complete mcx legacy rifle. I sold the legacy upper and I am now using the virtus upper on teh legacy lower. I didnt even think to see if the legacy lowers were compatible with virtus uppers. Question is...

Hi guys, Just thought I’d share my experience building my own Go Bag for my Virtus SBR and hope it helps some out there. After investing several hundreds of hours searching and researching (as I always do with most things I buy) for an edc bag solution that looked more civilian than mil, I...

I just picked up one of those Stop Box AR Chamber locks when they were on sale to see if it would fit my MCX Hybrid build with a Virtus upper. The it is a little tight, but it clicks into place without too much fuss and with no modification. Apparently the main issue with these locks was...

Hey Everyone! I just got my first Sig! MCX Virtus Patrol 16in 300BLK and been debating on the best optic set up. ACOG or LPVO?! Thoughts? I plan on running it with a 35degree off set red dot as well! Since it’s a 300blk I’m really stuck on if I should invest in the ACOG 300blk edition since I...

Howdy! New member, not new to guns. Instructor and former RSO, been shooting for 20+ years. Anyway, I've done a deep dive into piston guns and decided my next rifle is going to be an MCX. The question is, do I go with the Legacy or just bite the bullet and drop the cash on a Virtus? I will...

Hello all. Has anyone had their 5.56 MCX Virtus 16" barrel rifle cut down to 10-12 inches? If so, did the rifle still function properly without modifying the gas system? For those that haven't done it, would you expect any issues to arise? I am thinking that if the gas block assembly is the...

Any MCX/Virtus owners dealt with this? One of the many things I love my about my new Virtus is the 3 inset QD sling swivel mounts on each side of the rifle; forward, middle at rear of the receiver, and aft on the stock. Having the 6 sling mount positions built-in is awesome. I'm having...

Hello All, New member here and excited to join the SIG community. Currently just own the P229RX Legion and love it. This is my first gun in a long while (owned a shotgun years back). I'm in the market for a rifle mainly for home defense and marksmanship skills. Having never owned a rifle of...

Can somebody take a picture of their Virtus trigger for me? It can be in the receiver or out. I've got one of the LE/First Responder versions [not LE, but am a qualified buyer]. The rifle is black, no funky duty color firearms allowed in most departments, and they don't put any Virtus branding...

I'm keeping the one on the top, 11.5" SBR, sporting a Romeo 4S (wanted a 4T but didn't want to wait any longer). The 16" Patrol version was very tempting. I do want a full length upper but that's going to be a while. This part was a little more fun than I anticipated. Reaction rod and BEV...
