Edit-

Let’s keep the thread on Topic.

Update#3 Sound Data below. This data is courtesy of nfatalk.org.

Update #2 Below, New AAC Taper Flash Hider & QD Hub.

If you have had a Resto done and have a range report please post your findings here; I’ll start below my original post



556-SD upgrade to Ranger 5.

762-SDN-6 upgrade to Ranger 7.

Size comparison to SF SOCOM556-RC & Dead Air SMS762-MIL Sandman.

Haven’t shot them yet however the upgrade is incredibly well done.

$700.00 per and 4 weeks door to door.

Update #1

Had both cans out to a metering event in NE Georgia on Saturday. Event was hosted by some of the crew that operates nfatalk.org, and had present 3 B&K 2209 Impulse Sound Meters, calibrated to NIST Standards. Meters were set up at the industry standard 1M left of muzzle, shooters right ear and shooters left ear. Temp was in the range of 103 with heat Index, sunny & winds were calm.

Both cans were tested with one unsuppressed shot with no muzzle device followed by 5 rounds Suppressed using the included Direct Thread Hub adapter.

I will update this thread once all the data is posted to the master thread for suppressor data on nfatalk.org. It usually takes those guys about a week to compile everything and get it posted.

RANGER 5

Tested using an upper consisting of an 11.5” FN barrel, carbine gas, .070 GP, low pro standard gas block, standard full auto BCG, and a new, Vltor VCH charging handle free of my normal gasket maker at the rear of the charging handle.

Ammo tested was what I assume would be the loudest 5.56 I’ve got, Federal American Eagle XM193, 55 Gr. Muzzle velocity out of an 11.5 is some where in the range of 2770-2810 or so.





Can feels great with the reduced length and lighter weight. 15.2 Oz, down from 18, While not a huge decrease it is noticeable. Definite decrease in blowback was noticed. In its original form as a 556-SD gas was instant and in your face. I attribute the decrease to the vented baffles and slightly larger 6mm Bore. I specifically threw a new untreated charging handle in this upper to see how much was really coming back and was surprised how little there was. Pretty happy with it overall, this thing is probably going to reside on a .223 Bolt gun & BCM 14.5 Recce that I’ve got.

Looking at 135.8 Muzzle, 134.7 Left Ear, 140.5 Right Ear


RANGER 7

Tested using an AAC 9” Pistol Gas upper, low pro standard gas block, standard full auto BCG, standard charging handle with gasket maker at the rear. Can’t remember what AAC was opening these gas ports to…it’s the OG AAC barrel 4150 CMV, nitride, 1-7 twist 5R rifling.

Two types of ammo were tested using the same 1 shot unsuppressed, no muzzle device followed by 5 Suppressed in the Direct Thread configuration. Can was allowed to cool slightly between the two types of ammo.

Federal Fusion MSR 150 Gr. (Super) & Sig Marksman 220 Gr. OTM (Sub). Velocity on these is pretty well established at something like ~1669 & ~960 from a 9” Barrel. If anybody has actual chrono data on these specific loads from 9” barrel please post them up.





Once again the reduced length and weight were noticeable over the SDN-6 in its original form. 7.66” & 19.85 Oz down to 6.75” & 17.2 Oz. Reduced blowback was again very noticeable as this can has more vented baffles than the Ranger 5. It was really nice with both supers and subs and cycled fine, just really pleasant overall. This will stay dedicated to this gun and continue to reside bedside as it did before the Resto.

Overall impressions are favorable. Both cans met my expectations for what I wanted out of this whole Resto process.
Money well spent for me and I’m glad I did it, brought back two can that weren’t seeing much use and now definitely will.

If you have questions or your own reviews post them up, I’ll come back with sound data when I have it.

Update #2

I have no relationship to AAC other than being a user. I have been given permission to post these new items and review them, and to my knowledge I am the only non-industry, non-dealer to have them.











These are scheduled for release at SHOT, and will be available in both 1/2”x28 and 5/8”x24.

New 90Tooth V Thread flash hider:

90TV Flash Hider 1/2-28- 4.24oz, 2.59" OAL.

3 points of retention- Large Robust Taper behind the three prongs, new V-thread pitch which I am unsure what the actual pitch is however it much finer than the old course threads from the 51T mounts, followed by the 90 Tooth Ratchet. Differing lengths of relief on each tine so no tuning fork resonance was noticed.

Lock up on this thing is extremely tight, even hand tightened I needed a tool to separate them. Rocket will absolutely be need on the barrel or this flash hider will come off with the hub. Very good gas seal when shooting, taper and threads stay remarkably clean of carbon after removal.

90TV Flash Hider 5/8-24- 4oz, 2.59" OAL

New QD 1.375-24 HUB compatible Adapter

90TV (Tapered V-thread) Adapter- 3.44oz, 1.22" of added length, 1.77" overall.

Again the new Adapter locks up incredibly tight to the new flash hiders, machining tolerances between the two are very tight, no movement between the two at all. Everything that people didn’t like about the 51T system has been fixed with these new mounts and adapters. Ratchet Latch now has 4 teeth to engage the flash hider and looks to be user serviceable as it is retained by a pin the can driven out much easier than the 51T latches. Don’t know if AAC will provide this pin but I imagine they probably would if needed. I still keep the latch fully depressed when threading until fully seated, doing this on install & removal will extend the latch life as opposed to people wanting to hear that ratchet sound…

Will come back with more review thoughts after some more time with them but initial impressions are good.



End Cap has some interesting design features. I am told those 3 rings are there for flash mitigation purposes and the difference between the old cans and these new ones is night and day difference specifically under NODS.

Update #3 will be the sound data on these cans, still waiting for this to get published to nfatalk.org

Dunno, I got an emailed and called to order. I believe some other people here had the same. I’d shoot them an email.

The didn't have the Stamp available until late December. Probably why they didn't reach out to previous orders.

Mine shipped this week and they reached out to me to see if I needed one before they hit the website.

I ordered one online when I saw it here. Not complaining because i still got one.

Also noticed they wrote "needs a stamp mount" on my packing list. I really think they made that note, but sent me the note rather than keeping it lol.

If you were called by me- I put it on the form we kept as well.  When we finished up the first batch of STAMPs- I sent the email to folks I knew were Resto clients. Should have more in the next 2-3 weeks.  Waiting on a part to come back from coating then assembly.  This next batch should take care of everyone that needs one.

-New AAC guy

I wish I could have my gen 1 ranger updated. I never use it anymore.

Just out of curiosity, any chance an old SPR/M4 can be converted?

You have to send them a picture of the inside from the back end.

Do the 51T latch replacements still cost $75.00 and what's the turn around time?

I wonder if the Ecco Bravo Plan A adapter will work on the AAC Ranger series? The Griffin Plan A version doesn't work because of the lip in front of the threads. This Ecco version doesn't look like it has that lip, unless I'm mistaken.

*I know the Griffin Plan A Long version works, just looking to see if there is a more compact option.

I had my 556SD converted by ECCO to 1 3/8"-24, Does anyone know if AAC can still upgrade it?
I will probably send it in if so.

I'm almost positive they can. Send them an email. They're very responsive.

Yes atleast they did mine which had an ECCO hub conversion.

Just read the thread - looks like it is a go!

So...just making sure I understand...."HUB" = 1 3/8x24 threads for mounting systems?

Yes

Yes, but not all Hub will fit the AAC Ranger. Any Hub with a lip above the threads may be an issue.

Q plan B would be out as it has a lip? Rearden MFG should be ok because they do not?

This may be a stupid question but I'm asking anyway. Since AAC is rebuilding the can could they slightly over bore my 556 can to a size that would allow its use on a 6mm gun? They will already bore it to 6mm whats a touch more? I'd love to be able to use it on my 6ARC. I have a another can I'll be swapping from 6ARC to 6 Creed. This would eliminate swapping back and forth.

I thought I've read elsewhere that a suppressor's caliber can't be changed after the stamp has been approved and issued.

That might just be internet/gun store counter bullshit though, so I'd like to see what AAC says and/or what some searching of FATF FAQs produces.

I don't have either, but based on pictures of the mount, the Q would not work. The Rearden would.


I called AAC about turning my 762SDN into an Ranger 5 and they said the ATF would not allow it.

I just want to use YHM mounts (not the new one SRX?) with their flush (Kurtz?) can adapter.

I thought I saw in one of the interviews, the new AAC guy said the Ranger 5 does come slightly over-bored and can be used on 6mm... might be worth it to call them and ask.

It is over bored to 6mm but just to allow for a little free bore. I thinks it's nuts on 6mm so no go with actual 6mm projectiles. I have a KGM R6 (actual 6mm suppressor) and the end cap mics at .3030" the end cap on my M41K mics at .2999 Small difference. I don't care if they leave the caliber designation.556" I won't tell anyone. All that said, I'm sure there are some baffle design issues that would prevent it.

Yes they could. There is no atf definition or industry standard for overbore baffles per caliber
Tell them you have a sloppy host and want to be safe

Will they do it? Probably not

I don't know about the M41k, but this is the interview I was thinking of regarding the Ranger 5; skip to about 20:15:

https://www.youtube.com/watch?v=glvsgHhZ46s

He does say it's over-bored to 6mm, but sounds like it is centered around super short barrel applications... he doesn't say you can shoot 6mm bullets through it, so I think you're right... disregard.
Thanks

STAMP mounts back in stock on AAC’s website.

So I’m ready to pull the trigger on turning my 762SD into a ranger 7 or ranger 7 mini.  If it goes well I’ll have my 762-SDN-6 converted too.

What’s the turnaround time? When this mod is done, does the new silencer come with that basic fixed thread/brake adapter thing? Or does the can just come with bare hub threads and no adapter at all.

I know if I want to keep using 51T I have to buy a STAMP adapter thing… but I think I’ll just go direct thread and call it a day.  I don’t swap my 762SD/762SDN6 cans onto other rifles anyways.

Mine came with a direct thread brake

It's Hub compatible (mostly) and comes with a direct thread adapter. Mine shipped in 3-4 weeks after sending it in.

Same. Came back to me in 4ish weeks with a 5/8x24 direct thread mount installed.

Anybody get one converted to a Ranger 7 Mini?  How does it sound on short .300BLK supers and 16" .308?

I'm going to start with sending in the 762SD first and part of me wants to go big or go home and turn that long boi into a the Ranger 7 Mini.  Because a mini-can on a Tavor 7 bullpup or 8" .300BLK would be sweet.  Then again, another part of me doesn't want to end up with a small can that it nearly worthless.

Like... I have a Turbo K mini can. It's not "that quiet", especially on a 10.3/11.5" SBR.  But it's effective enough that I could use it for defense even indoors if needed for a mag or two without too much worry and it's small/light enough that it doesn't hurt the handling of small SBRs. And in that regard it's awesome.  I'm afraid of a similarly small .30 can just plain sucking enough though to the extent that the size/weight can't redeem it.

Can't tell you, but @JSGlock34 might. He had an SDN-6 turned into a 7 Mini and I'm buying it from him

I have no experience with .30 cal mini cans, but on 300blk, you can always just shorten the barrel length and not lose too much performance:  I have a V7 6.5" 300blk, and with the regular Ranger 7, it is about the same OAL as an 11.5" AR with no can.  It sounds really close to a 9" 300blk with the same can, and only gives up about 75fps (with supers of course)

I had a mini 7 done and used it on my 9” 300 BLk with both supers and subs. I was pleasantly surprised, it sounded just fine.

I had my 762SDN6 converted to Ranger 5 length which is shorter than Ranger 7 length but longer than Ranger 7 Mini.  I find it a great compromise, your mileage may vary.

So I don't have a .300 anymore; I had planned to use the Ranger 7 Mini with my 5.56mm guns.  It didn't take me very long to determine the Ranger 7 Mini just isn't a good match for 5.56mm, and I ultimately decided I didn't want to go back down the .300 rabbit hole again.  Hence why it is on its way to towerofpower94!

The Ranger 7 Mini didn't perform particularly well with 5.56mm at the Silencer Summit - which conforms with my personal observations.

I'm quite happy with the full size Ranger 5 though.  I suspect the Ranger 7 Mini will perform much better with the cartridge it is designed for.

Yeah I noticed it’s not awesome for 5.56 but thats something you would expect to be the case. But it works great for 300 BLK

Glad to hear. I was planning to make it my dedicated 300BO can I only shoot subs at this point, so a full size can seems like overkill when I'm only trying to quiet down ~11grs of powder in a 9" barreled AAC upper.

If it can serve as a debarker on a short 5.56, then that's icing on top, but I never expected some radical reduction in sound on a short 5.56 from a short .30cal can.

I’m also using the AAC 9” upper with the original 51T and the Stamp mount. I’m happy with its performance. Have plenty of 5.56 cans for 5.56 purposes.

Thanks for the info on your experience with the same can/host I’ll be using. Looking forward to the tyranny stamp arriving so I can pick it up.

@KSPeacekeeper  Using the AAC restoration program?  Did you just put in the comments “Ranger 5 Length Please”?

Seems like a great option.

Yes resto and yes specified Ranger 5 length.

I think this is the smart play...

I'll have my first 762 AAC can done at Ranger5 length and if the Ranger5 length is quiet enough that I think it could stand to lose another 1/2", I'll have my second 762 AAC can done at mini length. If the the suppression is not up to my liking then I'll have my second AAC can done at Ranger7 length.  Either way, a Ranger5 + Mini7 or a Ranger5 + Ranger7 represent notable length and weight reductions for the pair of suppressors compared to my current 762SD/SDN6.

762-SD   8.75"/27.0oz  (w/51T mount)
762SDN6  7.66"/23.9oz  (w/51T mount)
RANGER7  6.75"/20.2oz  (w/ DT adapter)
RANGER5  5.83"/18.2oz  (w/ DT adapter)
R7 MINI   5.38"/13.8oz  (w/ DT adapter)

AAC said they could redo the suppressor again if you don't like for a small fee. So if you get a Mini 7 and aren't happy with it, you can send it back in again.

How small of a fee... because the first fee isn't so small.

Unfortunately, I never asked. I got my resto during the Black Friday offer and was told that if I didn't like the Mini 7, I could send it back and get it redone. I'm sure AAC will let you know the cost if you email them.

That’s good to know. Even if it’s another $700 it’s better than just letting a can sit due to not liking it.

Well, my 762-SD made it to AAC for the conversion.  I specified Ranger 5 Length (5.8"). Coincidently, 5.8" is the same length as a Polonium-30... I wonder if it will be similar.  

If it sounds good on my Tavor 7 I might leave it on there and send my SDN6 off for the full mini treatment to put on the 8" .300BLK HD rifle.  

If the Ranger 5/7 thing just sounds too underwhelming on the Tavor 7, I'll either have my SDN6 converted to HUB by ECCO or converted to full Ranger 7 spec by AAC for the Tavor and put the Ranger 5/7 thing on the .300BLK.

Guess I'll fin d out in a couple weeks.

Does anyone know if the ECCO Machine plan B mounts will work on a ranger conversion? Looking at their photos of the mount it is hard to tell if there is a small lip after the threads or not.
