    My trust will be here any day now and I'm beginning to shop for a can. I'm new to this but have been doing some light research here and elsewhere. My question is what would be the best 30 cal can that can be easily swapped between my MVP 308 Patrol and my AR's in 5.56. I found the Lane Scorpion Magnum which I really like for price and dB reduction but it appears it is a direct thread and I think a QD would be better for multiple applications. Other strong contenders are the SilencerCo Omega, Rugged Surge 7.62 and Dead Air Sandman S. Any help or advice from the pros is greatly appreciated. Thanks.

    Whatever info gets thrown here would be interesting to me, especially since the muzzle threads on 5.56/.223 barrels is usually different than 7.62/.308 barrels.

    True, but most manufacturers offer QD mounts and flash hiders that accommodate both thread pitches.

    Well...... I would look at AAC 7.62 SD or 7.62 SD-6. It's QD mounted and has decent suppression, about 30db. I have never been overly impressed with any centerfire rifle can. They are all still a little noisy with full power ammo. Keep in mind, no one makes a "Hollywood" quiet rifle can, so don't get roped into paying for one. There are some dealers who will let you demo a can from them before your purchase.

    You probably already know this but MechTech is correct. Suppressors just muffle the noise down to a level where hearing protection is not needed or only minimal protection is required.

    Hopefully, but I doubt it will pass, the bill just recently introduced concerning the elimination of the stamp requirement. I think it was in the House. I haven't read up on the bill, just what news releases were out concerning it, so I don't know the details.

    I suspect that even if the bill makes it through the House and the Senate, it won't get past the President's desk.

    With a centerfire rifle and supersonic full power ammo you'll still want/need hearing protection especially if shooting at a range or anywhere with walls close by. A .308 makes about 152dB. Cut 30 from that and you're still at 122dB which is right up there with a loud rock concert. Prolonged exposure will absolutely result in hearing loss and incident exposure can easily ring your ears. Being behind the rifle helps since sound is primarily projected forward but it's still loud. I can't tell what's loud anymore since my ears have rung continuously since I was 15, thanks to one round of .44mag and lack of hearing protection.


    I have to do a little rant as hearing is a personal subject to me:

    You only get 1 set of ears. When you damage them it's not just losing functionality. That loss often comes with tinnitus which is bloody mental torture. I've spent 30 years listening to a loud 4100Hz tone that I can't get rid of and it only gets louder as time goes on. If you think you can get used to it try this:

    Set your speakers to half volume and go to http://plasticity.szynalski.com/tone-generator.htm set the frequency at 3425Hz and hit play. That's where my hearing loss becomes truly profound. I can still hear a little with half volume on but I hear it as almost a whisper. If you plug your ears you'll hear it like I do. Below that frequency I seem to hear pretty well. To hear 3425Hz at what I think of as medium volume I have to turn my speakers up to full and put my ear on or very near the speaker. Now, slowly increase the frequency toward 4100Hz. My hearing loss becomes rapidly very substantial above 3000Hz and becomes effectively complete by the time you get to 4100Hz. At 4100Hz or above I can't tell a tone is playing at any volume even with ear contact to a speaker. Let that 4100Hz tone play for as long as you can stand it. Now think of it playing only in your head so you're the only one in the room that can ever hear it and it'll do that for the rest of your life. Let it play while you try to watch a show on TV or listen to a song on the radio. Let it play while you have a conversation with your wife. Let it play while you try to sleep. You will eventually get used to it but it takes a number of years and never stops being bothersome.

    Protect your hearing like you would your eyes. Take it deadly seriously. Don't let yourself make your ears a casualty. As soon as your hearing is damaged you can never go back and I guarantee you'll wish every day you could.

    To be honest, I'm surprised my hearing is still as good as it is with me being an aircraft mechanic. I do make it a habit to wear some sort of hearing protection but there are times when you get caught without any. Apparently, my hearing is still pretty good since some people are surprised by what I do hear or over hear.

    Anyway, back on subject. Think of a suppressor as a muffler. Mufflers work better on some things than others and since there is generally a size and weight limitation to contend with, suppressors can't always be a big as they need to be to bring the noise level down to where hearing protection is not needed.

    Many suppressors are designed with sub-sonic ammunition in mind for various reasons but size and weight is one of them. If you ever looked at the size of some of the mufflers on vehicles with big engines that are really quiet, you would be shocked. Heck, even with my old Ford Ranger with a four banger in it, the thing was huge! I've also seen some videos where people have adaptors to use Wix oil filters as a suppressor. The filter they use is pretty darn big and negates the ability to use iron sights or (I suspect) any sort of optic, unless it is mounted really high.

    So, having suppressor will only reduce the noise but hearing protection may still be needed. Just not as much is needed. It depends on the round and firearm it's attached to. A 5.56 pistol or SBR would probably still require hearing protection (those SOBs are LOUD). Pretty much and .30 caliber round outside of maybe .300 AAC or Blackout will probably be in the same boat.

    I have a yankee hill machine 7.62 phantom stainless steel with qd mounts I have adaptors on a 308 , 3 300 blackouts and an ar 15 . I love this can it is rated for 300 win mag but my god this thing is heavy . If I was going to get another I would look at a yhm 30 lite or other similar models from other manufactures . I am considering getting a smaller can for my 5.56 rifles . I do wear muffs at the gun range but when hunting even with 308 super sonic loads it helps alot . sub-sonics through my to 300 blackout ar,s an 8.5 inch and 16 inch are pretty quiet but my bolt action remington 700 in 300 blackout is about pellet gun loud.

    Look at silence shop right now. They are having some killer deals on suppressors. In a 308 I have used a Griffin, AAC, surefire with QD mount and a SWR. Out of all of them I really liked the SWR the best, then Griffin, AAC then surefire. With a QD mount you may have some point of impact shift and then again you can have POI shift with a direct thread.

    I dont think direct thread or Q.D. mount have as much bearing on p.o.i. change as much as harmonics , barrel stiffness and weight of the suppressor. a good example is my mvp lr with a 20 inch heavy fluted barrel does not suffer from any poi change but when I hang the same suppressor on my 20 inch goverment profile barrel it changes 8 inches at 100 yds . the plus side is its the same every time . I do see how a rifle that dont have a concentric thread can effect the poi but we would probably see that evidence in the baffles or end cap.

    With running a firearms school, I see most all of them come through. I opted for the Silencerco Omega. I'll be using their ASR flash hider on both my DRD Tactical M7.62 and my MVP Patrol 7.62 so I can swap it out. With the anchor brake on the end, that's a soft shooting brake!

    Fixing to buy 2 more from Silencerco; the Sparrow for my rimfires and the Harvester Big Bore .338 for my DRD Tactical Kivaari .338 Lapua.

    I have an older swr rated for 300 win mag that I use on a 308 ar10 not sure what model it is. I purchased it in like 2004 ish on a group buy before they were bought by silenceCo. My buddy has the Omega and runs it on a dpms 308 Oracle and 6.8 ar. Very nice suppressor you just have to watch your barrel length with it. I shot the Griffin sportsman on a 308 bolt gun and the revolution 45 while I was looking at options for my mp5s that are chambered in 40. The store I shot it at told me that they had a gemtech raptor II in stock and they did not! So they made it up to me by letting me shoot their ammo and demo some cans. I haven't shot the specwar nor know anyone that has one. All my buddies that have 5.56 cans have AAC or Surefire and I have never been impressed with either one. I think they are more name then can. I didn't end up buying a Griffin but I did use their 40 cal 3 lug adapter on my F1 suppressor build. Got my stamp this past Tuesday and cutting my last spacer tomorrow.

    I just pulled the trigger on a Griffin Recce 7 mod 3. Can't wait to try it out.
