Suppressor for my SBR

[Blaster26]

I am looking to put a suppressor on my SBR; any recommendations? POI shift is not a big concern. I tend to keep my suppressors on my other guns a 100% of the time. I currently have two yankee hill suppressors. Rifle is a .308 POF 12 inch. Looking for low weight and short length. Is titanium better or would it be better for me to have heaver weight at the barrel?

Since nobody's responded, I will.

Titanium is not a great material for SBR's and/or heavy firing schedules. This is because of its thermal/strength characteristics. If you take it easy on firing rate, it would probably be OK, but check with the suppressor manufacturer.

At SHOT Show, we had a prototype of a 7" steel/inconel version of our 30BA, that goes on our BA mount.

Zak, how about some more info about this?

like availability dates, price, Db reduction, etc.

It'll be for sale later in the spring. It's 2" shorter but only 2-3 dB louder. Weight is around 20 oz. Price will be similar to the 30BA, but it's not 100% set yet.

Rifle is a .308 POF 12 inch

Most .308 Suppressors are rated for 16-18" minimum barrel lengths by the manufacturer -- shorter barrels have higher initial exit pressures and the design needs to account for this.

Check before you buy, or you may be voiding any warranty.

Mr. Smith thank you for the response. From what I have been reading I will need something with an inconel blast baffle at a minimum. I don't really shoot it heavy, but that is probably because I tend to only shoot suppressed weapons these days. Let me know if you think your product will be out by March. Thanks for your time.

I'd be interested in how much velocity is lost, compared to a 20" barrel? Thanks.

I have not measured the velocity loss. The reason I purchased an SBR in .308 was so it would not really be a factor in terminal performance as with a 5.56. If I come across someone with the equipment I'll give it a shot and let you know the results. I will try and do some real world testing with it next deer season. Of all things both my Remington 308 compact tactical and this SBR love 150 gr core lockt. I bought one box of every type of premium round I could find and they both shoot sub moa with a fairly cheap round.

Thanks I just assumed it was 12 for just about every company.

A typical 150gr load might be 1700 fps from a 20" barrel. According to QuickLoad, the same load would be going about 2350 from a 12" barrel, 2200 fps from a 10".

For comparison, a 10" .300 Whisper/Fireball/Blackout can shoot a 125gr at 2100-2200 fps.

 

[Blaster26]

best keep the range well under 200 yds, because your starting velocity with 150 gr (factory) boatail sp in a 12" barrel will be under 2300 fps, and big game sp's don't expand reliably in flesh below 1800 fps. What you essentially have is a 30-30, as far as hunting or long range work goes, do you know that?

Yes sir I am aware. I live in coastal south Louisiana we are lucky to find deer over 75 pounds. Most of my hunts I usually just take my grandfather's old Winchester. Even when I hunt bigger game out of state I rarely shoot over 200 yards. I am sure for the right hunt I would make an exception, I really just don't trust the light bullets on anything other than our little whitetail. My Rem is made for the high end 168s, it just does not like them on paper anything with a boattail it slings them out of MOA even at 100.

Check out the new - http://www.huntertownarms.com/k556.php. They work well and are reasonably priced. They are very user friendly for cleaning and maintaining. They are supposed to have a .308 on the way.

Thats about right for a 5.56x45 (.223) suppressor.
