Suppressor - .308 and .223

Soldatlamour · August 31, 2010, 12:47 AM

I have two rifles that I'm trying to set up for long distance shooting (my definition - 500 to 700 yards... maybe some day to 1,000).

Would a supressor help with accuracy?

Also, should I get a suppressor, can the barrel of each of my rifles be threaded to use the same suppressor ? (The barrels are thick, bull barrels.)

Thank you for your opinion.

It normally does help a little. I have a buddy that has a few long range suppressed 308's the problem is if you are shooting say an F-Class match the amount of shooting you are doing with a suppressed gun is A: not going to do much for noise because the round has to be supersonic and B: them suppressors get EFFING HOT FAST. Then your screwed because you can't see though the heat coming off the suppressor and it is too darn hot to take off.

Now if you are wanting a suppressor for say a hunting rig you have to first check to make sure you can do that. If you can hunt with a suppressor then it may help, then again you are suppressing a super sonic bullet. Your still going to get a supersonic crack.

A suppressor definitely helped my .223. They reduce barrel whip.

I use mine sparingly and have never had the heat wave mirage bother me. But yes... they do get hot quick.

It can help with accuracy. My 7.62SD fits on the same mount as my M4 2000 and M4 1000 but doesn’t “lock” as well on the M4 2000 mount because of tooth count on the mount. Either way the 7.62 SD is a lot larger can and doesn’t suppress as well as the 223 cans (bigger hole). You obviously cannot use a .223 suppressor on a 308, so you would have to go the other way.

From my understanding you'd have to get 2 suppressors one for your .223 and one for your .308. Also from what I've read and researched, besides the overheating and extended length there is no down fall to a suppressor. You get reduced sound, reduced recoil, and increased muzzle velocity. I say go for it.

A lot of guys are just running the 7.62 cans on their .223/5.56 guns. They say the sound suppression is pretty good too.

The downside is that the 7.62 cans are a bit heavier than a dedicated 5.56 can.

Sound suppressors are against the rules in NRA HP Long Range including F-class because the NRA ruled they count as "recoil reduction devices".

There is nothing wrong with shooting a .308 suppressor on a .223 rifle, provided you do not exceed the manufacturer's intended usage for the suppressor (eg a lightweight .308 suppressor on full-auto 5.56 is probably not a good idea).

You will likely need a thread adapter so the 5/8-24 .308 suppressor will fit on the 1/2-28 .223 muzzle.

With regard to heat, there are thermal covers for this purpose.

We actually took some video of this exact setup (30P-1 on a .223 rifle) over the weekend; I just need to get the video online.

.308 suppressor will work fine on .223, and in fact, if you want to suppress both, just get the .308 can. That one will do double duty.

Depending on the model of suppressor, you may be able to get quick detach adapters for both the .223 and .308; that saves the trouble of using thread adapters and thread protectors, and the can goes on and comes off more quickly.

I live in california and am disgusted by this conversation. Not your fault, need a new state to call home.

I live in Australia and feel the same about 80% of the threads

You have to jump through hoops to get a bolt gun here

I run the SEI/Fisher .30 caliber M14-DC can on my M14s and 7.62 AKM... it does enhance accuracy.

You are able to run the .30 caliber can on a .223 with the proper DC Vortex flash hider from SEI installed.

Here you see our Std. weight .30 cal. suppressor on a M4 with our Vortex being shot at 500 meters.
They found that there were no change of bullet impact at that distance suppressed or not, we were very happy as were they.

That wouldn't happen to be an M110 next to the fella in the bottom picture, would it?

You have a good eye for details.
