I am looking at buying my first can. I have a trust. I am ordering a new 5.56 upper, probably in 14.5 inch, but want the dealer to pin and solder the QD mount to save on the stamp and time thing.
Questions for those with greater knowledge than me: 1. I want to buy a can with a couple extra quick detach mounts. I am leaning towards Surefire, with Yankee Hill as second. I would love comments. 2. Yankee Hill supposedly has a noise reduction of 35 or 36 dB. I have not seen anything on Surefire. What are theirs? 3. Let's say that one can is 35dB and one is 30dB. Is that something I would notice? The most important thing to me is to be able to shoot without muffs on and still preserve my hearing. 4. Does Bravo Company do the concentric check, pinning, and soldering? I really like the BCM uppers is why I ask. If not, then what dealer sells LMT uppers that does this service? Thanks in advance! |

YHM makes a very good can at a GREAT price (they're the value proposition in the suppressor industry). Surefire manufactures a premium can, sparing no expense on the materials that the can is constructed of (which results in a higher price, of course). Surefire offers one of the best QD mounts available and you'll have the option to use a muzzle brake, comp. or flash hider. 2. Sound reduction between the two can will be very comparable, but don't get too tied up in db reduction on a 5.56 can (most of the noise you'll hear is the sound coming out of the ejection port and the crack as the bullet goes transsonic). Durability in a 5.56 can is far more important than db reduction. 3. Yes, you can hear the difference in a 5db spread. 4. I'd ask Bravo Company, I'm sure they can answer it for you. |

Thanks Major-Malfunction....
I want a QD flash hider/mount that can be welded on to make a 14.5 inch barrel 16 inches or more. Does the Yankee Hill QD or the Surefire QD do this, or am I looking at trying to find a 14.7 inch barrel? EDIT...OK, the Surefire FH556-212A QD mount adds 1.7" to the rifle's length. I could not find out about the YH mount?? Anyone? |

Just a side note. Here is what ADCO says about the AAC and Surefire mounts.
Pin Suppressor Mounts AAC and Surefire Suppressor Mounts $100.00
AAC and Surefire Suppressor mounts are too hard(literally) to pin as we do other muzzle devices so we have to charge accordingly. Permanantly attaching Surefire Suppressor mounts VOIDS the warranty of any suppressor attached to the pinned mount. I emailed them about a YHM and they said no problem. |

I think the best option is the GEMTECH bi-lock. I have the GEMTECH (Smith Vortex) bi-lock pinned and welded on my 14.5" woa barrel below.
This made an overall length of about 16.2" and totally legal. I did the drilling, pin and weld myself. The GEMTECH bi-lock offers the quickest mount and dismount available. Just a quick push, a 1/4 turn and its off.

Quoted: 3. Let's say that one can is 35dB and one is 30dB. Is that something I would notice? The most important thing to me is to be able to shoot without muffs on and still preserve my hearing. While I agree that the loudest noise with a suppressed 5.56 weapon is the supersonic crack, there can be a noticeable sound performance difference between various products. And that difference cannot always be measured in dB numbers. The dB meter is measuring overall pressure. It does not tell you other things like the duration of the sound, frequency, tone, etc. Thus, you can have one product that looks better on the meter actually sound louder to your ear. I use the dB numbers to tell me how close the weapon/suppressor package is operating to the magic 140 dB "hearing safe" level. And speaking of "hearing safe", boy that is a whole other conversation. Basically you need to worry not just about the dB numbers but also factor in exposure time. Speaking of ears, hearing is subjective because we all have different amounts of hearing loss and that loss can be in different frequency ranges. To oversimplify the example, think of a dog whistle. The doggie hears things in a different frequency so Rover hears me blowing the whistle but you won't hear it. Make sense?? If you are worried about sound the only way to really get the best answer is to try before you buy. And speaking of ejection port noise... Some suppressors reduce back pressure better than others. I have unscientifically come to the conclusion that the greater the back pressure the louder the operator notices the noise. And finally, brand loyalty is rampant in the suppressor world. You will find a lot of hatred for certain manufacturers. Try to weed through the info you gather from various sources and formulate your own opinions as best as possible. Understand that a lot of guys will answer your questions of "So, which suppressor should I get?" with the answer, "Get a XXX brand because I have one and love it." But what they fail to tell you is that they have limited or no personal experience with other products. So, don't be afraid to ask questions about WHY someone likes or dislikes a particular product.  Best of luck to you. Mark |

I will keep the Gemtech bi-lock in mind too since that will get me over 16. I wonder why Surefire voids the warranty when the mount is pinned?? I guess I will not be going with Surefire for the first one as I really want a 14.5" pinned barrel for this build. My next build will be an 11.5" gun, so all manufacturers will be fair game on that one. Thanks to all that replied! |

My best guess is surefire voids the warranty because if the mount is slightly deformed from the welding it can cause a misalignment and possibly a baffle strike. Thats just my thoughts I don't know for sure. |

I'm not an expert on items 1-3.....but I recently asked about the concentricity of BCM barrels over in their industry forum, specifically the 16" SS410 (as I am currently setting up with a YHM phantom mount.) They said they are good to go. I'm not sure if they offer shop services, but I know Adco does great work. |

From Tom at YHM:
"Yes, it will void the warranty if a QD mount is pinned and welded to a barrel. There is a spring washer on the mount that is a serviceable part that makes the ratchet mechanism on the suppressor work when you tighten it up, and this washer will probably need to be serviced at some point during the life of the suppressor and if you pin and weld the mount the only way to service it is if you cut the mount off as it is only accessable from the back of the mount when the mount is removed from the gun." I'm not sure if it voids the mount warranty alone or the suppressor warranty (probably just the mount), but it's something to keep in mind. If nothing else, just go with a 16" barrel. |
| Why not just get a 16 inch barrel and buy your preferred suppressor and not have to worry about pinning a mount and voiding the warranty. Seems like a lot of hassle to save less than two inches... maybe look at something like that gemtech barrel tensioning mount that adds no length to the barrel, seems if used on a 16 incher would fit your criteria for barrel length. Just an idea to throw out there, I don't know if it would work for ya. But good luck. |

You will probably be happy either way. 2. The 212 and YHM can should sound similar on 14.5" or longer barrels so weight and price are larger factors- the YHM mount weighs 4-5 ounces too. 3. When both cans are within a DB or two you probably won't notice which is better, but the Surefire [may] have lower sound at the shooters ear. Sound at the shooters ear may very when two cans have very similar sound 1 meter left of the muzzle. 4. Adco makes suppressor threaded barrels. They are probably the preferred supplier for things like that. AAC tested the 212 in this video series. The videos are long and the results are at the end. AAC testing the 212 |
