Any recommendations for an adjustable gas block? I think I'm pulling the trigger on a suppressor for my ar15. I keep going back and forth on the suppressor thing but for coyote hunting it looks like a no brainer.

Anyway, are all adjustable gas blocks the same or is there one out there you would recommend for use with a suppressor?
 
look at the accessibility and just read the thing, this stuff changes a bit year to year.
how short will be the barrel? from what i understand it gets more trickier when you go under 10". above 10 should be less problematic.

1.) Do not go cheap with adjustable gas blocks. It makes all the difference with the cycling function of your AR.
2.) Avoid the "set screw" style gas blocks and try to go "tool-less" as much as possible. Riflespeed and Strike Industries make a "collar style" AGB.

20 inch barrel.
 
Maybe Superlative for the bleed off and Riflespeed if you’ll be adjusting it rather than set and forget. Choices also depend on interior diameter/length of your rail.

That riflespeed one is slick. Makes it easy to adjust if I were to remove the silencer. Any idea if I can use my existing gas tube? I thought I saw somewhere I need a straight tube. Did not see anything about it on their site.

if gas blocks are of the same height - same tube will work. some damn designs may pin or lock the tube in the gas block, so that may be the only issue.

Another option is to get the Riflespeed AGB, and cut out a small access window on the side of your aluminum handguard so you won't need to remove the suppressor. Or you can get a pre-cut handguard from Wolfpack Armory made specifically for Riflespeed. This way, you can tune the gas quickly after removing the can.

I have a standard tube on my cheapo AGB and it works fine.
 
I know the OP is in Montana now but I have an AGB from @WojtekWeaponry. Made right in NH
 
hmm. with 20" i am not sure if it will need an adjustable gas block at all, really.

Yep, for 20" I would definitely get the suppressor and try it with the rifle "as is" first.

@peterk123 Rifle length gas system? What kind of can? Is it newer flow through design or traditional higher pressure one?

12.6 inches from the receiver. Have not decided on a can yet. I'm thinking a 30 caliber but not sure. Might go with a dedicated 556. I will visit my local shop after the first and talk to them. The guy there know his suppressors. Sells a ton of them. Any can recommendations you have would be welcomed.

Yes, that's a rifle length gas system.

Are you planning on using this can on other guns as well? Might be worth tailoring the choice to other guns first. Your 20" should be an easy host, as far as suppressing 5.56 goes, even with short K cans. I would try the can first to see if you want/need the AGB. If your store moves a lot of suppressors, they probably would give better recommendations based on what hosts will you run the can on. I would just cross reference their advice before buying to make sure they are not just pushing higher margin product.

p.s.: Keep the weight in mind when deciding between 5.56 or 30 cal cans. If you will be shooting off-hand, it will matter a lot more.

Thank you!

if this is a precision long gun and you do care of how the POI will shift some inch or so after that can goes on - then i would do a dedicated can, and only take it off for cleaning.
and would tune the scope to reflect that POI shift.
for a short tactical gun that spreads 2 or 3 moa anyway, can makes no real difference, if it is a dedicated one or shared or whatever.

That makes a lot of sense. Plus my hunting rifle (308) is not threaded and I have not convinced myself yet that I need the extra weight in the mountains. Although a lot of people swear by it.
 
I have an AGB from Odin works primarily so my brass isn't thrown in to the next county. I did have to buy some extra long allen wrenches for it though.
 
If you compare similar models from the same manufacturer, usually 30 cal ones weigh more.
and noticeably larger in diameter. all this is pretty personal, as those toys cost quite a bit, and it is important to understand of why you want to do that at all.
.223 does not smack your ears too bad to begin with, so, well, i will keep it at that.
i sometimes shoot my .223 with no ear protection, as somehow i have lived most of my life shooting anything with no protection at all and somehow survived... a simple blast deflector works well too.

but .308 and my other ones that shoot close to 3000fps - those guns do a nastier sound that rings for quite a bit, i would love to suppress those.

I find .223 to be very loud for what it is, especially in shorter barrel lengths. And to me it’s much more enjoyable to shoot suppressed.

Hit me up, I’ll get you sorted.

Bad advice, The Strike Industries block has a pretty nasty habit of disintegrating.

Nothing of what you wrote is anything worth espousing.
