I would like to add a suppressor to one of my AR-15s. Ops Inc. 12th Model has been recommended to me. I'd like to get other opinions form owners or guys that have used suppressors.

Help me spend my money!

You will find lots of people willing to give their opinions on http://www.silencertalk.com . I am not able to give any worthwhile opinions on various silencers as I make my own and the only 223 silencer I have heard up close was a Gemtech.

Rusty, Call and talk to Jeb at Tactical Hog Control. They run many many rounds through a suppressed 223 each year and Jeb will shoot you straight!

With that said I just received my Yankee Hills 223 suppressor without consulting Jeb. It was what my local class 3 dealer was pedaling and they looked good to me. Full auto rated and lifetime warrenty. Have only run a few rounds through it, seems mighty quiet!

Rusty, If there is one thing I've found is there is a lot of hype surrounding suppressors. A good tip I have learned over the years is you can only get an AR so quite. Most good cans will get the sound pressure to around 130-135dB. The action cycling next to your face is loud along with the gasses escaping. With that said, whats most important to you? weight? sound reduction? attachment? durability? price?I have six suppressors, 2 of them are 223 cans. I would recommend getting a AAC 7.62sd you can run it on your AR or any .308 caliber on down. Its fast attach, durable, fairly light and versitile. I have two friends that run this can on their ARs with excellent results comparable to my dedicated AAC spr/m4. I think Ops cans are great have read good things never heard one in person. My other .223 can is a stainless SAS 5.56 can, its dedicated to my 22-250 now but when I had it on my AR it did really well and was cheap. 7.62sd is on the left, spr/m4 right

Rusty, see my post that was one of the first on this forum. I have a Gemtech, which, with the QD mounts fills my bill very well. I use it on several different guns including my AC556 and my Sig 556. 223 sounds rather like a 22LR. In open spaces you don't need ear protection. It does get hot however! I suspect they all do.

I have a OPS Inc 12th on my 5.56 bolt gun and on a 7.62 bolt gun, both are VERY quiet. I opted for the OI because of how it attaches, 2 point. In theory it should be more rigid. The only draw back to the o.i. is that the opening at the business end is very small. This makes them quieter but makes precise measurements on attachment points critical. If your threads and collar are not concentric with the bore you will have baffle strikes. That said a good gunsmith should have everything concentric anyway. I also have 2 AAC cans on ARs and they are accurate and pretty quiet. They attach easily but do seam a little sloppy at times, but that does not seam to effect them. The OI does slide back over the bbl a couple of inches which is nice on the over all length. In my mind the OI seams to be a better attachment system but that is probably all in my mind. The reality is they are both great suppressor companies with great products.

I would not buy a 7.62 can for a 5.56. The 7.62 are 3-4" longer, much heavier and the .33-.35 hole will make a noticeable difference in noise.

AWESOME set ups!!!

Just mailed off the completed forms and money to BATFE.

I can't say enough good things about Leitrim Enterprises. Pat and Sharon have been very kind and most helpful. They took all the stress out of filling out the forms and gave me good advice!

I am buying the Ops Inc. 12th model!

I run a gemtech sandstorm 30 cal can on my ar. when I pickud it up my dealer shot it side by side with an unknown model 556 can and mine was suprisingly quieter. cant wait to get the 300 fireball complete

Matt

The 300 fireball (whisper) is nice. It is nearly copied by the 300 blackout. The Blackout case is a bit shorter than the whisper, but the most important difference is that the factory laoded blackout ammo has the bullet seated a bit deeper than the whisper so that the 20-30 round mags will hold more than 5 rounds without binding.

http://300aacblackout.com/
Existing AR magazines have a rib which normally contacts the 5.56mm case-neck. With 300 BLK ammo, the contact is on the bullet. Because the bullet is a larger diameter, the rib will push the cartridges out of alignment, and can lead to binding potentially resulting in Failures to Feed. For this reason, it is important to load ammunition so that the contact point with the magazine rib is on the bullet ogive in an area of about 0.250 inch diameter.

I load my 240 grain 300 whisper cartridges to 2.25" as this gives me the best accuracy. I avoid the jamming issues in my ar-15 mags by milling a .125" slot in the rib on the magazine.

I run an AAC SPR-M4 on my coyote rifle, but I also have and shoot an AAC Cyclone on my .308. Using an adapter from PRI, I can have the .30 can on the AR and it is just as quiet, so more versitile.

IMHO: The only advantgae the SPR-M4 has is the shorter length.

Good on you for the choice of the 12th model. Some friends and I were shooting long range and ran an impromptu test of several cans. One of the guys at the time was a dealer in NFA, and we had a good variety of suppressors, to include an AAC M4-1000, a SPR/M4, M4-2000 (2009 model), Ops Inc 12th and 16th model. The 12th model and the SPR/M4 were the quietest, with the edge going to the 12th. The 12th also had the least blowback through the action.

Specifically, the 12th and the SPR/M4 were tested on two Mk12 SPR's both with identical Compass Lake SPR barrels, using the same ammo.

If I were to place them in order, I'd say the M41000 was only marginally louder than the SPRm4 and 12th.

We did a sort of blind test. I knew who what firing which rifle, and I went back about 30 yards behind the firing line and the shooters took turns shooting the 12th, the 16th (on a 16" AR), and the SPR/M4. I could hear a slight difference in one, which I would assume was the 16th. The difference in the three was frequency by far over actual volume.

ETA- The guy with the 12th, about three months later, had a baffle strike with some Black Hills 77gr OTM. He called Ops Inc and Black Hills and Mike at Ops replaced the can for nothing and covered shipping of the damaged can and the new can.

I can't say he'd do this for anyone, but certainly stepped up in this case. The shooter was somewhat a known good guy and now works for Nightforce. Maybe that carried weight with Ops and maybe not.

ranb40,

tp555 at Paladin Machine Services has made a good many 300/221 barrels for the community. He now has 300 AAC Blackout reamers and is switching. He indicates the new reamer takes out just s smidge from a 1.355 300/221 chamber.

He is offering to rebore such 300/221 chambers and gauges. Mine is going back after hunting season.

Trying to ascertain if old ammo can be fired in the new chamber. I think it can be.

Interesting. Sounds like the 300 whisper could be fired in the 300 blackout chammber (safe?), but not the reverse. I will leave mine as a 300 whisper for now.

Ranb

Appears that the differences are primarily in freebore. Sort of like the differences between SAAMI 6.8 SPC and 6.8 SPC II.

They tell me that already loaded ammo is OK. Existing cases will be OK as well if trimmed to 1.355".

300 BLK may give high pressures in earlier chambers.

Got a call from Sharon at Leitrim Enterprises Monday night. My stamp had been delivered. Yeaterday my upper went to Tip Burns. Next week I'll head over to do the face to face transfer.

Once again I can't say enough good things about Pat and Sharon at Leitrim Enterprises in Spring Branch, Texas.

After hearing all the horror stories about the paper work process what I went through was no hassle at all!

I bought my can through my LLC. I strongly suggest that anyone wanting to buy a can do the same thing or have pat and Sharon help you set up a Trust.

You might try a sure fire. They guarantee no change in point of impact if you use thier muzzle brake or flash supressor to mount the can.

I am using the mounting bracket/muzzle break that comes with the Ops Inc. 12th Model. should do just as you describe!

Call George at Shooters Depot, 361-877-6927 and orderem for fantastic sound reduction. an Aries System.

Rusty,

I got two cans from Pat at Leitrim, and went smooth as can be, Great people to deal with.
Tried to go local with tac pro and messed up, my paperwork and check sat on a desk for 3 months before I complained enough, finally found it.
+1 for Pat

The 300 BLK has a fatter neck, to obviate the need to neck turn 223 brass. Swede Nelson at NOE is tooling up for a 247gr GC multi-cavity bullet mould just for this cartridge to feed in a standard AR-15 magazine.

My wife is getting me an upper and dies for Valentine's Day, bless her!

I just got a site called Tactical Innovations ! who have Suppressors !

I like the Coastal Gun XDS for the AR, they also make it in 6.8. Their Flash Hider Mount version attaches to a standard A2 flash hider in seconds and works like a champ. It's heavier than most .223 cans but it's solid steel and built like a tank. The screw-on version is only $379.

Kend,


thank you for the link. I see one in my future on my 300BLK.

Woo-Hoo!

Rich

Rusty,

I have a freind who has used an AWC for many years on his 223 bolt action and also his AR-15's. He recently switched to an AR with a gas tappet, forget which make it was. It shot alot cleaner than the standard Stoner gas tube. I think when you put back pressure on the gas tube it blows alot of crud into the magazine.

Some of these modifications have an adjustible gas port (like an FNFAL) and you can tune it for use with or without a can.

I dont think the gas tappet was any more quiet than a gas tube, but it was cleaner. You will be amused at how much you hear the recoil spring when shooting the supressed rifle. (I never noticed it before).

Have fun. My favorite rifle is my AWC 22 LR with wrap around supressor. (Bolt action Ruger).

Andy

I recently built a 300blk out of a Noveski 10.5 inch barrel and a bunch of other parts. With a M16 lower and a Gemtech HVT and subsonic loads, it runs 100 percent and sounds like a staple gun. At 15 yards I got a FA 20 rd group of around 2.5 inches with it. Incredibly quiet and controllable. probably the most accurate FA I've ever fired including.22's-Rob

RGB,

did you know NOE is going to make a run of moulds for a 247gr GC or PB .308" for the BLK?
At about 1100fps it should be fun in a pistol AR.

Rich

I just run 200 gr MK's in my DI gun. On gas piston I have is a POF .223.-Rob

RGB,

Well, yeah, but your wife gives you a bigger allowance than my wife does me!

Rich

Rusty,

Holy Crap that was fast turn around on your Form 4!!!!

Enjoying the can?

Yes, I am. Great fun. Not "Hollywood" quiet with regular ammo. Like a 22 mag, but quiet enough to hear the action function!

I hope to get a .223 barrel for my M 03 and add a mount to that. Ought to be great fun!
