You are absolutely fine my man! Yeah the new sigs are metal printed titanium or inconel. I haven't been given any info on them yet other than whats available to the general consumer so i can't say whether they are fa rated or not officially but their videos shows it on the new ngw program belt fed (in the new 6.8 which is substantially hotter than 308) so i'm assuming eventually they will come out and say yes. For comparison, the TDS printed cans are belt rated and no minimum barrel length. They show theirs on a 12" FAL which would destroy most cans. They claimed you would melt the barrel before you could melt the suppressor because of the properties of inconel (i think they put more nickel in it or something like that?) having a higher melting point. Sooooo if the sig's are even similar inconel there won't be anything out there in the category its designed for that can hurt it. My biggest draw was the accomplishment of designing and making a can that has LESS blowback than a rifle WITHOUT a can. That's impressive in my book. Along with that they say the new blackout specific can (which can run any 308 but its internally designed for blk) is 4 decibels quieter than the previous srd762ti that was (unofficially) the quietest 300blk setup thats ever been made. Now i dont have a db meter but to my ears its noticeably quieter so id say their claim is substantiated. At least to MY ears it is. Very impressive. I had to go out of town for my other job so i didn't get hardly any time with it and didn't shoot it fa but when i get back in a few weeks thats my plan. Making a video comparing the cyclic rate without, with old, and with new. Should be interesting. I did one a while back with the TDS so i want to replicate it with the new sig designs now. I'll see it i can link that video its pretty cool. I had another guy split screen it and set the timing the same in slow motion and you can see the backpressure differences easily.
Heres the video, i just reposted it as im not computer savvy: Facebook
If you're better with tech feel free to snag it and post it within a post so others can enjoy, and wait for part two after i get home....
Have a great night!
