[ARCHIVED THREAD] - OPS INC Small - Medium - Large (Page 1 of 2)
Posted: 7/28/2006 7:03:38 PM EDT
 12th model on 18" SPR barrel - the rifle can 15th model on 14.5" M4 Barrel - the carbine can 14th model on 11.5" barrel - the SBR can The 14th is 3oz lighter than the 15th and 3/4" shorter. You trade db for size, but I think its great for a SBR. As the 12th model is quieter than the 15th, the 14th seems just about the same difference. Shooting I couldnt really tell much difference. I asked the folks at the other end of the range to listen and they said the 14th was louder, but it wasnt much more than a noticable difference. These two SBRs have the same 11.5" barrels, to give you an idea of size

Its not advertised, or listed as available. I dont believe they think its as good an idea as I do. It mounts the same as the other models. Aftering seeing pics of SHIVAN's suppressor, I REALLY like the brake acting as the blast baffle on a SBR.

I dont think OPS gives a $hit what the form 4 world thinks about how they test their cans, and I doubt you will see OPS spend a penny marketing/advertising for the same reason. Groups have been buying them for many years, are very happy, and keep buying more. After hearing several different suppressors, I can tell you the db numbers 3' from the shooter are only part of the story. Stand 20' from a couple, then move down range next to the target. Not all cans sound the same. For some folks, its more important to hide where the shot came from. If the db at your ears is your concern while plinking pop cans at the range, put a full size 12th model on your SBR. Look at the SBR picture threads - most all the SBRs have full sized suppressors. If size, weight, and being able to hear after you pop off a round in a building, or next to a buddy are important to you - buy accordingly. OPS INC suppressors, dont have a pretty finish, dont come with fancy packaging, dont have a "QD" mount, but they are damn quiet, light, built like a tank, accurate as you can get, and have a very well established track record with the .mil in the US and Canada. They work, and they'll sell just fine by word of mouth. ETA - I'm not sure on cost, I'm still hoping they officially be offered. I have a couple classes I'll be taking mine to to get feed back to pass along regarding interest. |
(edited to be nice) Dude, how the hell is he supposed to know why OPS INC tests the way they do?  They build a military grade product, for people who NEED the things....period. I don't think they will be selling T-Shirts on their web site with pictures of monkeys advertising their product.....lol.  Steve, The more you post info on the 12th model, the more it makes me want to steer away from my next build of a plain jane 16" ar, and build an upper for use with one...lol. ( I have a nice dept. issued M16A1 with the small push pins that is screaming for an SPR upper) I have 6 months to wait for my next tax return damn it ......lol.. |

What is the reason for the two lightning cuts in the pictured Vltor gas block? Did you shoot the 14th on the SBR and the 15th on the M4? or both on the sae barrel? The fourteenth model looks cool. It seems like there is a real market for cans that are marginally effective but small. It would be interesting to see the 14th sound tested side-by-side with the AAC SCAR-SD to see how they compared. I suppose the Ops probably has it in the weight race. |
|
Hmmm, is the 14th still hearing safe outdoors? I was pretty much sold on the 15th model but now.... I'm not sure I understand what you were referencing with Shivan's build. Can you provide a link to the applicable thread? Are you referring to his strike issues with his AAC? |
I assume that since your an industry partner that you might also sell these and might know, plus it looks like you own them. You seem to know an awful lot about OPS Inc and one guy who builds them posts here from time to time. Mabye he has the inside scoop on the questions. Seem like if you didn't know a simple answer might have been: 1. I don't have a clue what they cost. 2. I have no idea why they test suppressors from 90 feet away and the military who supposidly is buying them doesn't require Mil spec testing for them but does for everybody else. Avoiding the question is no way to answer it. |
I'm sorry - it was well past my bed time when I posted. 1. - cost will be around $850-900 range. 2.- suppression testing - I believe OPS feels its more important to mask the shooter from the target than the db level at the shooters ear. Its something you have to hear. My .308 with a the Gemtech HVT is a dream to shoot without hearing protection. Much quieter than the my SPR with the 12th model OPS INC can. Standing 20' away from the 2 being shot together, the 12th model is without a doubt quieter. |
Decoration I guess?
both on the same barrel
Thats what I think, but I dont believe the manufacturer agrees.
You and me both. I have SCAR-SD that was approved on the 13th, but has not yet shipped from AAC.
yup |
My notes are in an Excel file at the shop, but the 14th model installed on an 11.5" barrel, measured from the bolt face is just a tad(1/8") under 16". The full sized Surefire can is, of course, quieter. |
If you ask me, every suppressor I have heard on an 11.5" barrel is not hearing safe. I have friends who think it is, but my ears ring. The 14th is definitely a mission specific suppressor. Its a compromise of size and db. If I could only own 1 OPS suppressor, it would absolutely be the 15th. SHIVAN put his can on a short barrel and blasted/melted away the first baffle. SBRs are hell on suppressors. |
Interesting. Thanks for the info. I am interested in the GemtechHVT, is the 12 Ops a 308 can? |
From what I understand it was not a melted blast baffle but bullet strikes. It looked melted due to copper from the impacts globbing on to the blast baffle. |
You remind me of Silvers.... |
Edited to be nice. |
Forgot to mention earlier, all 223 cans do this, as its one of the classes primary offerings. Wasn't it this gentleman  that sold the military in Vietnam the shot location theory when firing a suppressed 223?
|
I was thinking the same thing. I've come to terms with the fact that, the more I learn about cans, the more I realize that I don't know anything about them. |
|
I had the oportunity to shoot/hear all three at the range yesterday. One of bigbore's other customers was there with his new-to-him M16 lower. WOO HOO! I was intrigued by the 14th model for sure. After hearing/shooting all three I like the 15th the best overall, but the 14th was not much louder and yet it was much more compact. Steve keeps teasing me with these OPS INC suppressors... I am going to have one to dedicate to my .223 offerings. Right now I cross train with a 6.8SPC SRT can on my 11.5" 556 barrel. It's OK for that purpose, but not ideal. Here's Steve with one of the cans: OPS INC can ETA: As a comparison here's the owner's 10.5" RRA barrel with: No Can |
Half the people who try my putfile videos can't see them.  If someone knows of a better video host I'll try that. The file is a WMV file. I used to post MPEG2 files and got complaints that some poeple couldn't see those...I see that 22 people have viewed that file though. |
You could try "you tube". |
|
OK guys, try these videos instead: OPS INC FULL AUTO 12th Model M16 Shorty Note the sound comparison. We'll need to get more video of the 14th model..... |
http://i77.photobucket.com/albums/j60/5uLu/ops_sizes.jpg Which one of these has the "utility finish"? Or which ones are KG koted? Does the Brake and Collar have the same matching "utility finish"? Thanks. |
No, I just didn't want to throw on a suppressor that looks like that 14th model on a black rifle. |
Ahhh, thank you for the clarification k31user. |

I've spent the last 13 months sending uppers back and forth trying to get my carbine completed. This is #5. #4 finally appeared to have gotten it right, but I had decided to move on to another mfg and upgrade to a FF rail (I chose CMMG, this time - this is the first CMMG upper I've had). I refuse to play upper-tag again, and I'm certainly not paying to have something done to it that should have been there in the first place. I've had lots of problems with other parts of my build from various manufacturers -- good customer service is nice and all, but it still adds up to a pain in the ass when you have to deal with it several times at once with several different companies. I appear to be cursed. It's new, so I'm just selling it for what I paid for it and moving on. Nothing else wrong with it, I'm just sick of mailing my crap all over creation and back. (edited to add - no one seems to want one, so I'm just having CMMG do it; they quoted a very reasonable price. In the meantime, I completed the fingerprint song and dance and I'm waiting for the local LEO's to send me back my signed form 4) |
4 out of 5 people who heard them both today said the 14th was quieter. The 5th person was the owner of the SCAR-SD  Standing about 30' away from the shooter (11.5" barrel), the SCAR-SD made my ears ring. The 14th did not. Two completely different sounding suppressors. YMMV. |
I didn't know that the barrels needed a certain step for the collar? Which barrels can the collar mount on directly form the barrel maker? |
30FEET! Holy shit. Do you mean the 14th also at 30 feet? Or are you comparing with firing the 14th? |
Colt, LMT, BCM. etc. all have the step in the barrel, as do Armalite, RRA, and Bushmaster. I just have to know which barrel you have so I get you the right collar. |
This post is pretty much worthless unless you can hear for yourself. I was standing 30' away from the shooter taking turns shooting SBRs with each suppressor. The tone/frequency/pitch, whatever you want to call it is very different between the 2. I'm not saying one is louder than the other, just that the sound of one made my ears rings because it had a sharper sound. |
The big one is the 12th model, which is really the EX-Large one, because I need to take a new picture with the 16th model for small(14th), medium(15th), large(16th) and ex-large(12th). 12th and 15th models are in stock. |
I'm slightly confused now, what's this "16th model" you reference? |
