    It "Maybe" helps a little more gas fall out of the port, rather than find all the cracks and crevices a non-swiss cheesed CH would.

    Did you say Raptor?

    This one, while a little dated, has a deeper groove. TBH, I don't really notice a lot of gas from this rifle, but it's an all-around pleasure to shoot.

    I know this was about CH's but wasnt that super special Surefire BCG supposed to help eliminate blowback by delaying the unlocking time, or something like that. Somebody here bought one and was going to review it but cant remember who...
    The best way to survive a violent encounter is to be the one inflicting the most violence.

    That would be UW, of course. I think I remember him saying it wasnít worth the premium over decent carriers?

    Thereís the Surefire optimized bcg - works a little different then the other 2.

    The bootleg is suppose to help also but more so with directing gas other places., along with the Gemtech carrier ( that bootleg makes)

    Best mitigation of gas face goes to...

    The BRN-180!

    What gas does make it to the receiver travels back through the barrel and dumps out the port (sorry, lefties). There's literally no place else for it to go.

    OSS suppressors do seem to work as advertised. I was fortunate enough to mess with a couple. The gas blowback was greatly reduced on the AR I shot and the cyclic rate on full auto remained about the same on the SCAR-17.

    Size and weight are a bit of an issue but OSS has improved the designs somewhat in these regards.

    This is exactly the reason I want to get one... at least for off hand shooting

    After shooting a tuned SCAR16 and G36C suppressed, it's hard to go back to your standard AR with all the gas in the face.

    At this point I wholeheartedly recommend you get one. Their backorder cycles seem relatively quick, so watch for a good coupon and do the thing. These can be had for $750 with a sale and a coupon. It's a heck of a bargain in terms of AR value.

    My bestie got a new OSS Helix for his first can and he likes it well enough he may never know true "gasface ".

    The 180 provides all that fun for a minimum savings of $2,000. Plus, you get to keep your optic.

    So a quick tid bit today, I finally got some extensive use out of my SF optimized bolt carrier today. Had a 3 day entry class this week, and on the final day, I decided to use one of my personal carbines for the live fire drills. Decided to throw in the SF carrier and a Dead Air Sandman K at the end of a CMT build with a 10.5 Ballistic Advantage Barrel. Gun has no other gas mitigation systems and no adjustable gas block.

    Barely any gas in the face after 600 rounds. It was a pleasure to shoot and I would say there is no more gas in the face than a non-suppressed gun. I'll need to run the gun a little more, but so far, I'm impressed with the results and looking forward to building another dedicated suppressed gun around a 2nd SF carrier I have.

    I understand you may not be able to answer this yet, but figured I'd ask the question... Would you say this is a better purchase if you're trying to shoot/tame a SHORT SBR versus a "standard" SBR (like a 14.5)? Seems like the 10.3/10.5 (and maybe the 11.5) might benefit more from this than a 14.5. Obviously gas port design comes into play, so I understand it's a loaded question. Other than my 416s, I tend to build/request reduced gas port designs, so I guess I live in a "more" perfect world...if that makes sense. But even given that, an ADCO 10.3 suppressed still pushes the gas, even if it's not as bad as a commercial upper.

    Although not a lefty, but I donít have any gas face issues at all with a 10.5 BCM that always runs suppressed. Itís just a bone stock work rifle. I only added a Giessele FBI contract CH for the sole purpose of eliminating any chance of snagging on kit......itís a little more rounded than an ACH.

    After shooting suppressed a little while now, I can join in and say ARs donít suppresse very well lol

    I have been using a few things, since I like tuning my shit and want it to run the best I can get it..Still changing shit around

    But in my 10.5Ē i was using a bootleg carrier for a while and works well for what it is vs a std carrier.. Besides making the upper so much more dirty.. But, again I canít leave shit alone, So swapping around buffers and springs currently (any suggestions for baby smooth , perfect function, Iím listening:) ..)

    Also just swapped in one of those BRT suppressed sized gas tubes (.059 port) Ran up for a quick test the other day...tons better, runs softer and lot less gas.

    I also use a SLR adjustable gas block on my 12.5Ē 308 (first adj gas block I ever used) and with a pri fat boy gas toob and H3/armalite spring & A5 length toob, it shoots softer then my 556 ars it feels like

    Now I moved the bootleg over to the grendel
