Lightweight QD Suppressor Mount

[Chris_in_Idaho]

I've been narrowing in on the lightest and shortest QD mount system for a can on a hunting rifle and ended up with these two. One is from Diligent Defense, it's their Zilch adapter (Titanium) and their planB style flash hider (stainless). The other is from Ecco Machine, it's Nick's titanium version of the Griffin planA, and a titanium Griffin brake. Both are super short and compact. Both are nearly as lightweight as a direct thread adapter. Anyone see advantages or disadvantages to one system or the other?

Anyone used planB or planA and have feedback?

I use plan A. I already had a Griffin Optimus and got Griffins "long" plan A for my Polonium. I like it for my ARs, as it's great to move from my home defense AR pistol to other rifles quickly, but I mostly hunt direct thread using a Gemtech Tracker.

If this is for your hunting rifles, why the QD? More room for error IMO. Direct thread has never let me down.

I solely run the A419 sidewinder system on everything including the 223. Muzzle adapters are 2 ounces. Easy to swap from a can to one of their brakes if you choose.

Do you just hand tighten your direct thread cans?

I don't trust the square shouldered direct thread to stay tight without having been torqued on with a wrench, and I like to be able to swap the can between rifles or remove it when I'm riding in with the rifle on my backpack. A tapered interface locks together much better with just hand torque.

I'm currently using direct thread for weight savings, but these two QD systems are just as lightweight, both within an ounce of my DT adapter.

Once the adapter is rocksett to the can and the brake is rocksett to the rifle I don't really see what can go wrong.

What room for error do you mean?

Do you ever have any carbon issues? I've seen quite a few people claim the threads being forward of the taper is a problem, but it never seems people who have actually used it.

I think QD systems have a place in ARs where you can have different thread pitches and some of my rifles are that way. However at this point I pretty much just dedicate a single can to that gun. By the time I bought qd attachments and brakes for all of my rifles, I could get two more cans.

Little bit of blue locktite and I'm good to go. The Residual seems to stay in there and creates no issues swapping them out by hand.

By all means, go QD if you want but it's just one more variable in the accuracy game due to tolerance stacking. Cans coming loose is extremely overblown IMO. When you get where you're going just reach up and double check it. I've never had one fail me.

Now with very long shot strings I have noticed it loosen up but it's nothing that simply tightening up by hand couldnt fix. I'm talking 25+ shot strings and that was before I started to use locktite.

All my bolt guns I just direct thread as well and never had any carbon issues or them coming loose. As @SloppyJ said just give it a quick twist check. I am assuming your using this for hunting, not like your back to back mag dumping it like an AR.

Also for carbon reference pretty much everyone I know that has a 22 can is direct threading them and rimfire has to be the dirtiest most carbon producing ammo I can think of and between myself (I have two 22 cans) and my friends I can't say I have never seen or heard of anyone having carbon issues on the threads. Inside the can is a whole 'nother story... wow can those things build up carbon!! I have to clean my 22 cans about every 500rds now, I use to do it every 1000-1500 but the baffles were so caked up that I now do it every 500 so it does not build up and get so bad.

I prefer Plan B. I have used it since it first came out. I like that the threads are behind the taper, so the threads stay carbon free. I have never had one lock up… and I’m talking about 10’s of thousands of rounds through AR systems.

I've been using Griffin taper mounts for over 10 years. Right now, I have their Ti muzzle device on my Defiance and one on my Tikka both in 300wsm. I have the Ecco ti Plan A in my Scythe, its amazing. Griffin makes great stuff, I much prefer Plan A just for the variety they offer. I have Plan B for my AAC 762sdn6 that Ecco converted to HUB, and it works fine, just not as good as Plan A from my experience.

No issues, even playing gun games with 60+ round course of fire.

Any of these LH thread on the QD hub mount to brake interface?

Nope, that's why I'm rocksetting all the threads except for that interface.

I know Xeno is LH threads.

As is the a419 hellfire/sidewinder system, which I've been running. I've been anti direct thread, as I always remove my cans after shooting. I'm hard on shit and would likely forget to put a thread protector on. With qd mount, there's a sacrificial barrier there that'll protect muzzle threads and crown if/when I do something stupid. However my new deadair nomad ti XC, I'm tempted to put one these 0.7oz ti direct thread adapters on, for my lightweight rig.

Properly torqued, I've never had an issue with my Griffin taper mounts coming loose. Now that I have them on everything and never switch anything around, I probably should rockset them.
