Well, in about 5 months I get to put my hands on my first suppressor. With the help of everyone here, I decided to get a Dead Air Sandman-S. If you own one of these how bad is blowback? I will be using it on a PSA 6.8, DPMS LR-308, Remington SPS Tactical .300AAC, and a 5.56(I know, I need more dedicated cans. I'm working on it).
So, will blowback be different on each of these, or is it a non-issue with the Sandman -S. Again, it's my first suppressor so I'm not very familiar with such things. If it will be an issue, how can I decrease it? Thanks! |

I'll look in to it. |

Last time out, I ran my SBR a bit wet. It didn't take too long before I couldn't see through my eye protection. I put a gas buster charging handle on it. I never really realized how much blow back I was getting. (Gemtech Halo)
FYI: A Ceiner kit will not run with a gas buster. Keep your old charging handle in your Ceiner box.

Sandman-S is a very low back pressure suppressor, so you should be ahead of the game mitigating blowback right from the start. If you have issues, look into tuning the rifles then. (Adjustable gas block, etc)
Blowback is a pretty personal thing in my opinion. Some folks are very sensitive to it, other's not much at all. Out of everything suppressed I've shot, there was one host (a Tavor) where it was awful. The rest, I either didn't notice at all or it was mildly annoying for a second. Bad blowback is to where you can't empty a semi-auto weapon without crying and looking like you've been at Willy Weed's Potapolloza all day. It's like Satan is vomiting into your eyes and nose... Most noticeable blowback to me is mildly annoying, meaning I get a little smell in my noise and it slightly stings my eyes. I would equate it to those of you who use contacts.... right when you put them in and there's that second or two of discomfort but you can still see and function. Or, you get some dust in your eyes and blink a couple times to resolve it. I think it's important to realize if you are sensitive to it, or if it is actually bad blowback. We have clients that use the same host, same ammo, same suppressor as I've used many times and they think the blowback is bad, where as I think it's nonexistant on that setup. I'm not trying to make anyone feel bad if they are sensitive to it... maybe I would try to say "cowboy up" but I'm highly sensitive to dryer sheets. If anything comes in contact with dryer sheets it makes my body look like a 14 year old boy's face. Some guys can't handle blowback, some guys can't handle dryer sheets. |

I'm definitely in the dryer sheet camp with you on that one! Ejection port noise is closely tied to blowback. Most every can out there that is boasting awesome at-muzzle numbers will have MUCH higher numbers at the shooters ear. Especially those that were designed for bolt actions that are then used on semis. If you can barely fit a muzzle device (or it has to be shortened) in the blast chamber, then it's a strong indicator of more blowback and noise for the shooter. Like Goloud and others said, you'll have to see how the suppressor works on each platform. Be ready to play with some buffer weights and gas blocks. Also, a good test to perform when you are shooting is to take out your left ear plug (if shooting right handed) and see if you're ear will still ring with each change. If your hearing is already a little cooked you may need to take your right plug out.

Quoted: Blowback is a pretty personal thing in my opinion. Some folks are very sensitive to it, other's not much at all. One thing I'd like to add is to remember that there is a difference between 'blowback' and 'dwell time'. I experience very little blowback when running a 762 can on a 556 host but it still has significant dwell time. The video below shows a 762 Omega on a MK18. When un-regulated cycles about 200RPM faster and has increased recoil vs regulating the gas.  |
