The Q plan B adds about the same length (~.2”) as the Plan A, but lacks tool features for dudes that twist the whole thing off their muzzle threads. The ones that add tool features to Q-pattern mounts add another .2”-.3”. That’s not a big deal, of course. The Griffin Plan A is also available in longer lengths on the adapter side, if desired.

Putting the taper on the rear allows it to have much more surface area within the envelope constraints. TBAC has talked about this on the Hide. I’m not sure how much that really matters vs more subtle engineering decisions such as the angle of the taper or the thread pattern. I don’t have a way to experiment with that because I’m not a machinist.

When I say “better”, I don’t mean that one will make you lose your house and the other will make you a millionaire.

It's funny you mention the tool issue, because there's exposed wrench flats on both the Rearden Atlas and any of the Rearden mounts to achieve what you discussed.  On the Q Plan B, I agree with you.  Ironically, I don't like the Plan A because there's no EXPOSED wrench flats on the flash hider, only on the front end of it.

But there's 30 million choices of mounts/muzzle devices for a reason.  Because people like different stuff.

I recommend and stock Rearden because most people don't want to or need to pay for a robust QD setup like Rugged Dual Taper or Dead Air KeyMo.

Check the second paragraph of the post you quoted, where I mentioned that non-Q branded Plan B compatible mounts have tool features. (Edit: I didn’t mean to sound this abrasive)

Also, there are tool features integrated into the rear of Griffin’s taper mounts.

That doesn’t change the lack of exposed flats on Plan A or normal Plan B.

The Spanner tool on the mount, but not on the FH.

If your Plan A muzzle device gets stuck into a welded on, integral taper mount (not a thread-off Plan A mount) there is a slot in the back that can take a pin spanner or a large ‘screw driver’ made from bar stock (Griffin sells such a tool).

Nice tools.  Those require removing the FH from the barrel to unstuck the mount/can, correct?



ETA:  Regardless, the Griffin isn’t junk by any means.  I simply prefer the design of another brand.

Correct. However, I think the way people discover their muzzle device is stuck in the can with any of the common taper systems is when the mount twists off of the barrel because it wasn’t tightened or threadlocked. I personally haven’t had a need to access the back of the muzzle device with a wrench while it’s attached to a barrel. Griffin does make mounts like that, but without the flash hider/brake/comp part, which probably isn’t what would appeal to most on an AR. Sweet for a bolt gun, though.

No purse swinging occurring…it’s easy to not know about the features of a device. Or perhaps it simply doesn’t do what you want, and the Rearden devices serve you better.

I haven’t tried that, but it makes sense. Not too surprising, they like to make front caps that can be removed with a coin.

Just buy a bolt and a nut in the thread pitch of the muzzle device. Thread the bolt in the stuck muzzle device. Tighten the nut against the back of the muzzle device. Then hammer on the bolt with an impact.

I've just been running YHM QD mounts for a better part of 10 yrs. When applicable I appreciate cans that have HUB threads, and I slap in one of YHM's QD adapters.  I have one of Q's Porq Chop and I'm quite honestly baffled (lol) why they made the Cherry BOMB XL use some wonky ass M27x1mm threads. I'm stuck with that mount, and they don't sell the XL with 3/4" muzzle threads, so no easy way to mount to my 338 Lapua. Then as mentioned the Cherry Bomb is not a great brake, so now I have to hope they make the Bottle Rocket for the XL :|

YHM QD isn't the lightest, newest, or most sexy but damned if it doesn't work and work well. Taper with acme threads behind it and a secondary ratchet for more retention.

It's not plan A/B simple but it's not far off. I don't have a ton of YHM mounts anymore but have no complaints about their system.

I'll add a +1 to Plan A or Plan B. Griffin Dual Lok seems extremely secure but I'm not convinced it's necessary outside of meeting requirements for contracts.

Revival Defense just launched their own mount in SS and Ti that can be installed with a AR15 wrench as well as some muzzle devices.

It will either have a can or a blast shield on it most of the time.  Only time I'd use a thread protector would be if I was fixing the bayonet.

I'm super new to the suppressor world (my first suppressor was approved on 4/1), so take what I say with a grain of salt.

I went with Plan B for all my mounting - 9mm PCC, 300blk AR, 5.56 AR.

From what I've read, Plan B seems to be the closest to an "industry standard" that exists. There are a number of manufacturers that make Plan B compatible devices, and there are a variety of muzzle devices available (A2-style, 3-prong, single/multi port brakes).

Also, Plan B apparently adds the least overall length and weight (direct threading aside), though the difference doesn't seem huge.

Moving my suppressor to different hosts and back, I have not noticed a change of zero in my limited shooting.

FPM Gunworks has a 2-port Plan B brake that will get a 14.5 to 16.  Liberty Precision has even longer devices that are a combo FH with a single front orifice / brake plate.  The Liberty devices push the mount feature forward so that a 13.7 can make 16 and still fit typical blast chambers.  

Strike Industries, KAK, KVP could all jump on the format if they saw enough market return. They may not see the potential.

Same here, and I just ordered a Polonium K, but I got the ASR mount and flash hiders because I have 2 of the FHs on rifles now and their blast shield.

Now that I see FCD makes FHs, I might have to see if I can cancel the ASR stuff with CA and go Plan B... no pun

You can't go wrong with any of them unless you are backed into a compatibility corner.

My personal preference has always been DA Xeno due to aesthetics, reverse thread and price. But I switched to Griffin Plan A due to the combination of wider range of barrel thread patterns supported and a much larger muzzle device selection available.

Hey no issues man. It's a technical forum which is why I corrected you.

The absolute values aren't very different. I think plan a adds like .2 and plan b adds .35ish on the shortest ones. Relative dimensions that's a 75% increase but overall it's still a small amount. I don't have a set of calipers so excuse the in-exact amounts.

Edit***something a lot of manufacturers don't disclose is how much the entire system (muzzle device plus mounting system) adds in a HUB can. Some Plan B mounts may only add .2ish inches but that's not including the muzzle device between the shoulder and the entrance to the mount. The pictures below show what I'm talking about

Just to make sure I understand.  

Plan A has threads in front and taper in back.

Plan B has threads in back and taper in front.

Some say plan A is better because it’s .2 in shorter?  Is that really a deciding factor or is that only for the “how close can I get it to the handguard crowd” crew?  I’ve never ran a gun for a long period of time and said, damn, I wish this thing was .2 shorter with my suppressor.  I’m also not clearing closed quarter ships or structures so maybe it’s a thing?

Some say Plan B is better because the taper in front helps to keep the threads clean and less likely for the suppressor mount to seize/ get stuck.  

Xeno is similar to plan B but has LH threads.  

Plan A and B seem to have more muzzle options with some being lighter, heavier, longer and shorter.

Plan A, B and Xeno could have their exposed threads damaged.

I have a mix of plan b and Rearden mounts and Q and Ecco machine adapters. Very pleased. Everything but some legacy AAC 51T stuff I have is is plan b.

Some say plan A is better because it’s .2 in shorter?  Is that really a deciding factor or is that only for the “how close can I get it to the handguard crowd” crew?  I’ve never ran a gun for a long period of time and said, damn, I wish this thing was .2 shorter with my suppressor.  I’m also not clearing closed quarter ships or structures so maybe it’s a thing?

Some say Plan B is better because the taper in front helps to keep the threads clean and less likely for the suppressor mount to seize/ get stuck.  

Xeno is similar to plan B but has LH threads.  

Plan A and B seem to have more muzzle options with some being lighter, heavier, longer and shorter.

Plan A, B and Xeno could have their exposed threads damaged.

With regard to the taper/thread arrangement, I don’t give it much thought. Q makes them in both orientations. The Full/Half Nelson has the taper behind the threads, the TP/TC has threads behind the taper.

Both are a taper mount, and both have a wagonload of options. So I consider it a wash in that regard. The big selling point? Griffin wont ship to Wa. Reardern and Liberty (Among others) have no problems shipping to Wa.

So, given the mechanics are "the same" and the available options are "the same" I think I'll side with the companies (And mount type) that will actually sell to civilians. Plan b/Rearden all the way.

You've got it.  The caveats with each brand are minor. It's mostly just personal preference.

Technically, they do all have exposed threads and yes the threads could get damaged. They are very coarse threads though, so much less likely to get damaged than bare barrel threads. I've never worried about it. I've never seen anyone complain about damaged threads.

I know Griffin does sell a Plan A thread protector  if it is a concern. There is no DA Xeno thread protector (DA said they don't have one and I've never heard of an aftermarket version). I don't know if there is one for Plan B or not.

Both FCD and Liberty make Plan B thread protectors that I’ve seen.

Most mounts are seemingly rather obnoxious muzzle brakes, and the suppressor threading makes it easy to spin on a blast shield when a can's not mounted, making an ersatz linear compensator.

It wouldn’t be hard (though perhaps not robust) for the blast functional features to thread on in front of the forward threads or taper. No can: unscrew brake orifice plate and screw on bird cage.  Suppressed: unscrew bird cage and screw in brake. Long hunting rifle: no forward feature.

It’s one more threaded interface to screw with but concentricity tolerances wouldn’t be any concern.
