I need help on recommending a suppressor for use on my 3 rifles: LWRC M6A3 14.7"PA 5.56, LWRC 8" PSD 6.8, Larue OBR 7.62. The store rep recommended the AAC 762 SD. Any experience on this suppressor? Other suggestions?
Thanks.
 
Re: Multi-caliber suppressor suggestion

Your 8" PSD is a no go..... AAC only warranties their suppressors on 10.5" barrels and up. The issue is unburnt powder and if the bullet can stabilize enough in that short of a tube.


The new 51t 762SD is a wise choice though. There are a ton of options though. The thing that will help us guide you is, how much are you wanting to spend and do you want a QD setup? Or are you willing to go thread on?

If thread on, do I need to deal with torque accuracy and how inconvenient is it? Would one suppressor work on my different barrel threads, or do I need more thread work there?

I'm getting in a can from Griffin, its a direct thread. A member here makes great thread adapters, shipped to your address for cheaper than anywhere else.
 
Re: Multi-caliber suppressor suggestion

See if you can hold your horses for a month or so. A little birdie told me silencerco is prepping to release a rifle can series. Their Osprey pistol series is damn amazing on multiple calibers, just think the possibility of their rifle can.

I have Innovative Arm's Solution Can. Its a Direct thread can so I have 5 adaptor for different rifles. I love the can. Great company also! He is a all in one stop. Awesome machinist also.

Sounds great: but metal or titanium, thread on or QD on brake, price? If I can hold the urge until then, I'll look forward to Silencerco's version. It's not like I can get it tomorrow due to tax stamp...

It seems SAS products deliver a lot for the money, based on feedback on this forum. Their titanium is same price as AAC's standard version. Anyone using SAS 762 on 6.8 and 556? Anyone recommend the titanium over the regular model?

Re: Multi-caliber suppressor suggestion

I personally own a 762-SD and love it. My 762 has the 18 tooth mount and I like it so much I am ordering the new version with the 51 tooth mount. I had a problem with the can loosening on my semi-auto guns and my 51 tooth M4-2000 does not have this problem. Get one with the 51 tooth ratchet mount and you should be pleasantly surprised.

True, the store rep that I purchased the PSD from had an AAC 762SD and offered it for $729. I almost made an impulse buy, and decided to research. And I learned that his can was the older style, which some complained of loosening after firing. One even had a baffle strike. The 51 tooth ratchet is new and didn't see much reports on it, but figured it must be less prone to loosening. If I order from him, I will be requesting the 51 tooth ratchet version.
Most posts that I read suggest minimum barrel length 10.5" for suppressor use. But since the 6.8 powder burns quicker - would a can be safer than a 223 for use in this very short barrel (8")? Am I just inviting trouble? Tell me if I need to completely stay away from trying to suppress the 6.8 PSD.

I'm sure it does, since I can't find bad reviews. But I have issues with their price. A $400 flashlight is bad enough, but their suppressors are twice others in this already expensive hobby. Sure pride of ownership, but are the incremental benefits worth the price increase?

Ti on short barreled rifles is a no go. To much heat.
 
Re: Multi-caliber suppressor suggestion

762SD works for me, and a buddy. I screwed up and got the SPR-m4 first for my 556, then a 762SD for my 308. A buddy learned from my expensive mistake and just got the 762SD for both his rifles. Works great, and just as quiet on 556 as my SPR-m4. Don't mind having the SPR-m4, but you sure don't need it if you have the 762SD.

Just put the M4-1000 mount on your 556, and the 762SD mount on anything bigger and you only have one can/tax stamp to buy. Love it.

Re: Multi-caliber suppressor suggestion

I am also looking at the 7.62SD for multiple caliber use. I have looked at quite a few now and I think that I am going to go with the AAC. Seems like there have been many people who are completly happy with their purchase of one.
 
Re: Multi-caliber suppressor suggestion

I to have a 762SD on my GAP built 308 with the 18 tooth and it is great. I can't tell how pleased i've been with it. The only problem that i've had with the 762sd is when i don't have the can attached and am just shooting with the break, I about blew my ears out. Once you get a can you won't want to shoot without one. I have the blackout mount on my 22-250 and it is a fun coyote gun.

If i were to do it all over again, i'd get the 51 tooth, and maybe something in Ti.

Re: Multi-caliber suppressor suggestion

the thundertrap is what we use for work and they're so damn heavy compaired to the AAC. I've also shot side by side with an employee at the range with fellow employees there and i had a lot of the guys come up to me later on in the day to say that the AAC can was much quieter.

Just my personal observations.

Re: Multi-caliber suppressor suggestion

..

No doubt your Thundertrap is heavy, its old. If your AAC is sounding quieter than the TT, its very old.

TT cans have been made for 30 years and stayed on top of the curve throughout the same period. Judging between cans requires knowing the production model year of the cans in question. AWC wraped the titanium TT in stainless to eliminate the high freq. ring of titanium. They were comparably heavy (unless your TT is all stainless, then it is HEAVY) until the newest models.

Now they are 100% titanium, the only deep penetration 100% welded, 360 can out there. The issue with titanium isn't just one of lightness, or even frequency modulation, it is the effect of titanium when exposed to high heat. There is only one way to insure that titanium in high round use can sustain perfect baffle fix to the outer envelope and that is through welds that are not just surface based.

Before you write the newest AWC thundertraps off the list. Go and hear one and see it.

Less than 17oz, Full Auto rated. Fieled for 27 years. The unit below is one of the last batch to go to the MARSOC.

Again, are you shooting full auto?

P.S. With an 8" 6.8 round your work is cut out for you finding a can than will really get the job done. Your issue has to do with the balance between modern baffle configuration AND the volume/design of the chamber to do any meaningful suppression on a 6.8 SBR with an overbore can. The same holds true for your SBR .223 if your going to use an overbore can. You have a challenge as most of the cans out there will do poorly on 2 of the 3 configurations you have. Most will say its fine to just mount an overbore can on anything, it isn't, is just barely OK at best with standard barrels, add the SBR and there are only two I know of that will get the job done. Both require a stretch (an additional baffle and chamber). So know you might be saying "But the neat stuff is all going mini", yes they are and they all sound like 1983. Once they go hot, forget it. Also, don't forget to add back into the suppressor weight totals any QB hiders.

Good luck and most importantly, start listening to any cans BEFORE you buy it.





 
Re: Multi-caliber suppressor suggestion

I run an AAC SPR/M4 can in 6.8 on a Noveske 12.5 Crusader with a switchblock,,with SSA tactical loads it sound like my Ruger 10/22 Mag. I agree with the above post, try and sample some cans before you buy.
 
Re: Multi-caliber suppressor suggestion

Thanks for the great feedback, it certainly shortens the learning curve in this unique hobby. Based on all the glowing reviews of the AAC 762 SD, I will be ordering it from my dealer holding my PSD. I made my decisions for the following reasons:
1) Manufacturer is in Norcross, GA. Not sure if it makes a difference that it's 30 minutes from my house, but figured transfer to my dealer and availability may be more efficient.
2) Great reviews, including in this thread.
3) New 51T ratchet mount seems to address what little criticism it has attained; namely some users have noted the threads loosening during repeated fire.
4) Although made of SS, it is only marginally heavier than titanium offerings out there. Since I'm not living in the desert carrying this everyday, the extra 6 ounces don't seem significant.
I'm pretty certain in this competitive market, that I would have been pleased with any of the offerings out there. As for the 6.8 PSD, I may get a dedicated can later since it's a whole different beast.

I appreciate everyone's help, and I'll post pics and comments when I receive it.
