Curious about one thing for someone who has used a suppressor. The Armalite AR-10 SASS boasts having an adjustable gas block to optimize the gas for use with a suppressor and prevent mis-feeds. Has anyone had any experience with this system and what do you think? Have you had any feeding problems without adjustable gas systems when using a suppressor on a semi-auto? Thanks.
 
Re: Adjusting gas-block and suppressor

I do not use an adjustable gas block with any of my suppressed AR's and I have never had any issues related to the suppressor, mis-feeds or otherwise.

I have shot suppressed AR-15's at carbine classes and I have done a couple long range classes with my suppressed AR-10 and none of them missed a beat. IMHO adjustable gas blocks are a work around, if the rifle is built properly from the beginning, to be shoot suppressed, you should not need one.

If you want to turn the gas return off to make the rifle a single shot, then I can see the need for one.

Actually an adjustable has many uses on a well built rifle. Not only can it help to compensate for the extra gas directed into the action when running a suppressor, you can also tailor the gas to different loads which can help with recoil and spotting hits.

Smokeshwn,
I've got an Armalite AR-10 SASS with the adjustable gas-block. So I was curious about how effective it is from someone that has experience with suppressors and/or adjustable gas blocks. Since I know Armalite builds a pretty good rifle (it ought to be for what I paid for it) I guessing it will perform well with or without a suppressor. I don't have a supressor for it yet but it's something I'll acquire in the future for my rig.

Yes, it is and for a while I used the Armalite adjustable gas block, but it made no difference in my shooting so I removed it and went back to a normal gas block. One less moving part.
