Suppressing a shorty 308?

General silencer discussion. If you want to talk about a specific silenced rifle or pistol, it is best to do that in the rifle or pistol section for that brand.

Suppressing a shorty 308?

Post by eastern_hunter »

Am thinkin' about mounting a suppressor on a 12.5" 308 piston AR. I know it will only moderate the beast ...

Anyone used a 7.62 Saker for that kinda thing?

Haven't tried the Saker but I had an AAC 762SD on my 12" LWRC REPR and it worked very well. While I don't have any numbers it was very comfortable without any sort of hearing protection.

I have done a couple of integrals on 11" LR308's with good results, my 762 suppressor on a 12" LR308 with 175gr black hills runs in the 142-144db range, they are rated for full auto to an 11"bbl, curtistactical.com check out the ST762FA or the QA762FA depending on whether you want direct thread or brake attach.

The pressure at that muzzle is nuts.

FWIW, that's one of the setups that the 762-SDN-6 was designed for. In particular, a 12.5" HK417.

That's what I'd choose for that application.

seen SCAR's in country with short barrels running the SDN-6, ran well but had Concussion like you wouldn't believe. we took a vote and wouldn't let him shoot from inside the vehicle. much worse than a Benelli M-4 shotgun (only other weapon system in the rear of the vehicle) I know he broke the window with concussion from the muzzle (Can)

yes, even with a can, it's no joke.

That concussion problem is exactly why I really wish FN would scale up the F2000 or IWI the Tavor to 7.62. All of the shortness with none of the ridiculous blast.

Haven't shot the shorty 308 yet ... is due in soon.

Have shot shorty 11.5" M16 w the AK brake and with can. WIthout can concussion is pretty wild ... much worse than with A2 FH! With can is not bad.

FS2000 and Tavor with can are pretty decent. A bit better than the shorty 16 w can.

Going to be interested in the 12.5" 308. Bet it is loud as all heck without a can! Hope is tolerable with good can. Don't expect it to be quiet ... just tolerable. Can is in NFA jail so will have very bad manners for a while.

Will try to acquire the Desert Tactical short bullpup 308 when it is available. Has to be better for sure.

Like many keltec products, the RFB is a really cool idea with a really crappy execution.

I don't even like the noise from my 16" piston 308, I can't imagine how bad a 12.5" would be.

Indeed ... can is in NFA jail for a while so can only comment now on it unsuppressed ...


POF-USA P308 is VERY LOUD and the shock waver is significant for sure. Recoil not bad at all. Have just rough sighted it with an EoTech and M80 ball, but seems is going to be quite accurate. Is dropping spents in a nice pile ;-)


Would not want to shoot it in a confined space!

Well, were talking "shorties" here. How much power do you need for CQB? 300 BLK gives you .30 cal option in a standard AR with standard mags. It outperforms 5.56mm. It's purposed to equal/exceed 7.62 X 39 and .30-30 Win. for example.

I too was on the hunt for the perfect .308 SBR, but "perfect" is subjective. 300 BLK fills the bill.

I don't need power for CQB because I don't have fantasies about urban warfare.

A short .308 will still out range a short 300 whisper/blackoutwith its rainbow like trajectory. The short .308s aren't quiet but only a fool will expect them to be.

To each his own. That's O.K. I'm not a 300 BLK salesman or anything. I also don't have "fantasies" such as you described. However, I acknowledge the very real possibility that one day, I may need to use any or every firearm I have to defend our family and home. There are different firearms, for different applications. I obviously don't purpose a long-barreled, bolt action rifle for inside-the-home defense. Yet, I don't purpose a G19 for long range deer hunting use either.

I love the .308/7.62 X 51. It is my favorite rifle cartridge. However, it's not the only rifle cartridge, not is it the best for very short, or very long range. I'm just saying that for a short-barreled, suppressed .30 cal option, I couldn't make the .308 fit the bill as well as 300 BLK has.

I see on POF website that you can get the POF-USA P308 in a 12.5" SBR. That'd transfer on a Form 4. Anyone know if you can buy the 12.5" upper and lower separately and do it on a Form 1? If using a trust and eFile, seems that route would save you, oh, 8 or so months right now.

... chuckle ...


I do already have a suppressed 300 BLK SBR that works very well indeed! I do like it. Question was not either/or. Question was aimed at "what is next."

Other approach to hastening the stamp might be to buy a P308 pistol and do an efile Form 1.

Call POF and ask. If they won't do it, call Hogan Guns and ask them. Hogan actually does all the machine work for POF, and are in the same building as POF.

But honestly after seeing first hand the issues that the POF/Hogan guns often have with reliability, I'd strongly suggest building an SBR SCAR 17.

PWS sells their shorty upper separate.

300 BLK is pretty much a neutered 308 SBR given the same bullet weight, but without the crazy loudness and concussion.

Overbuilt cans like the Saker/Specwar are probably best for a shorty 308.

Fair assessment. I can't disagree with that overall. 300 BLK is optimal however, with lighter (110 gr - 125 gr) bullets for supersonic use and heavier (220 gr or so) bullets for subsonic use, rather than the average .308 bullet weight of 150 gr - 180 gr range.
