Who's got suppressed AC's?

[Slow Hand]

I've got a thread adaptors coming to put my .308 can and a future .22 full auto rated can on my AC556. Just wondering how you who've suppressed them like them. I've only shot one suppressed M-16 and was amazed at teh gas blowback. I've got my AR threaded for my .30 cal can and am taking it out tomorrow. I've RTV'ed the charging handle so hopefully it's not as bad as I remember!

Anyways, is there much blast at teh reciever? I've heard that M-1A's can be kind of rough, so I didn't know if the Mini-action was the same. I've also heard that a .30 cal can on a .223 gives less blowback.

What about .22 cans on converted AC's? I've got a full auto can in process, so it'll be a few months before I can play with it, so I'm curious to see how a suppressed full auto .22 will be!

Thanks for any feedback.

I'm in the process of making a 9/16-24 to 1/2-28 adapter for my ACC Element can. Will be using it on my AC (When I finally get it) with a Ciener kit for .22 LR.

be careful

I had a Tact Innovations 22 fullauto can, and mine loosened up and I got a slight strike. I use 20 rd mags and check my can between mags, so it loosened up enough for a slight strike with-in 20 rounds...I took the adaptor off completely after it allowed my can to loosen up again this time after 10 rounds. I was told to use some lock tight, and others said to use a lock washer. My buddy and class3 dealer warned me against using the lock washer as it tends to throw off the streight line of fire and you are apt to get a bullet strike. After all the crap I decided to wear my hearing protection when shooting my Kac.
The can will go on something else. Hate to rain on your parade but a word of caution my save you some big bucks.

Appreciate the warnings. I've been told that a few wraps of teflon pipe tape will help hold it in place as will a prodict called Roc-Set. It's basically a higher heat version of Loc-Tite. I will be very careful with either can on there when the adaptors come in. And I agree with your dealer, lock washers are a bad idea with cans!

Ran my AC with AAC M4-2K.

Alot of fun.

But it gummed up the action and the gun began to fail to feed / function after about 100 rounds.

That might be due to a need to open up the gas port a slight bit more.

I ran about 200 rounds through my 18" barreled AR today with the can on it. It was lots of fun and pretty quiet! Had no issues with functioning in a 'finicky' AR action, so I"m hoping teh AC will do well! I've ran my AC to about 1500 rounds in one day without a single malf, so I"m assuming it'll be pretty reliable even with teh can on it.

I use double wave washers on my threaded cans to lock them in place and have had no problems with loosening or misalignment.

The main problems with a standard split lock washer are that there's no guarantee of alignment and the split part can gouge either the barrel shoulder or the can's mating surface. The wave washers that McMaster-Carr sells are precise in thickness to better than my calipers can detect.

What kind of washer does Ruger use to lock their Flash Suppressor in place?
Picture?

I'm sorry; I don't know. I don't actually own an AC556, but I have threaded cans on several FA weapons and the wave washers work great on them.

It is a star washer. It is the exact same washer that is used for the stock liner screws.

... or a crush washer.

Thread adaptors came in today. Got one in 5/8" for my .30 cal can and one in 1/2" for my .22 can. The OutBack II will be for semi-auto only (maybe a few short bursts) but I've got a Thompson Machine full auto rated one on teh way and it'll be ran hard on the AC with the Ciener kit!!

Here it is with the .30 cal can on it. I"m going to load up a few subsonics and test them out in teh back yard later this evening....

Yes, the subsonics are VERY quiet!!
