No problem. I appreciate the replies. Besides, you've gotta have a little fun with this, no?

Don't worry, you ain't the only one!

Piston AR's get just as dirty as D.I. AR's, just in different areas. Some major advantages of owning a gas piston system is that the receiver and BCG runs cleaner and cooler and you don't have to worry about gas blow back when shooting suppressed (unless you get a PRI Gas Buster charging handle on a D.I. system).

You still have to clean the piston area of the gas block...

Most certainly!

Well, yeah. But the BCG and receiver running cleaner and the gas blow back are what I meant. I mean, I know the dirt still goes somewhere, even if it would be nice if it magically disappeared. The BCG running cooler is one I had not considered until one of the guys who works on guns at one of the LGS's mentioned it.

So any thoughts on the 7.62x39 in this discussion? I am not sure how much more accurate they would be in a Sig 556 or even 516 compared to an AK, or how dirty/clean they are compared to the 5.56/.223 (in case that matters with a suppressor), or how their performance is effected suppressed. I tried looking, but I guess I'm asking an oddball variant of this question.

Here is my 2 cents.

If you're going to buy a suppressor, you may as well buy a 308 caliber suppressor.

Before anyone flames me because that wasn't one of the choices listed, here's why.

You can shoot both 223 and 7.62x39 both through a 308 silencer (or even 308, 762x54 and 300 blackout, 30/30, 6.8, 270, 243, 223, and any other comparable caliber through the 308 caliber silencer).

You cannot do the same with a 223 silencer and are a lot more limited with one of those. If you bought one in it, you'd be stuck with shooting 223 and smaller through it (ie 22lr, 17 hmr, 223, 223 wssm, etc) so the 308 silencer is a lot more bang for the buck (no pun intended). The only thing you'd have to do to use the larger diameter silencer on both large and small calibers is either use a thread adapter or have whatever barrel you're using it on threaded for 5/8-24.

And just FWIW, a piston upper/gun will run cleaner when using a silencer because they add a lot more back pressure, and thus DI guns will deposit more funk in the receiver as a result.

I have not purchased a suppressor yet but I already plan on getting one for a 7.62 for the very reason you mentioned above...

Anyone who would flame you for that isn't very bright anyway. F. F

Crap, didn't mean to send yet. Look at YHM phantom and similar that will allow you to use a 7.62 suppressor with a QD mount. You can put their QD flash hider on all your rifles and swap the can at will.
