I'm getting a separate 11.5" upper in the works. I would love a switch block, but due to the lack of rail options, I think I want to go with a low profile adjustable gas block.

Which is the best setup? I want low profile enough to fit under a tubular rail like a Seekins BAR, NSR, etc. But I want it to be simple to manipulate. I mainly want adjustable gas for suppressor use.

Thoughts..?

I don't think there is anything that is as easy as the Switchblock other than the WAR reciever. Personally I use an adjustable gas tube with my suppressed 11.5. I had to drill out a small hole in my top rail for the allen wrench, but it works good. I set the screw once and have not moved it since. Works fine.
I would love a Switchblock pinned to an 11.5" Noveske barrel, but my setup works great now so...
There was a gas block that had some slide metering device that could be pushed with a bullet tip through a set of rails. I can't remember the name, someone will help. It looked ok, not too crazy about it enough to buy one.
Good luck.

Yes, But how rapidly can that block be adjusted. If possible, I want a quick suppressed mode setting, and then a quick, unexpressed setting. I'm not familiar with how one manipulates that block.

Looks like a set screw. I do not adjust mine. They get carboned up and do not like to move too well. Set it and forget it. Shoots reliable unsuppressed, and smooth with the can.
Why would you shoot without the can anyhow? I get mabey 5 rounds off and the can is on for the day. Every so often I need to hear a loud gun. It's just rude.

Really...hmm. Makes me want a switch block. I don't like the idea of not being able to rapidly change from suppressed to unsuppressed. I don't know how often I would shoot with or without the can because I don't have one yet. I expect the biggest advantage to the can is at night, and on an SBR knight use is probably the most practical. Not saying that shooting guns with cans isn't pleasant, but they are heavier, and I just don't know yet. I really want something that can be adjusted quickly.

I read that the syrac adjusts in 1/4 turn increments. So it "clicks" if so that can't be too hard to adjust on the fly right?

Check out this one...have never used it but it looks closest to a suppressed/non-suppressed setting like the switchblock.

How about the Innovative Arms WRA Upper with the two gas settings? It wouldn't interfere with any rail. Palmetto sells them.

SLRrifleworks.com makes a slick one. I have one on my SLR rifle and since you were talking about rails check out their handgaurd. They call in the "intrepid" slim profile that flares out at the tip to rails. But I know their block is adjustable cause when I was ordering my rifle we talked ablout it.

Damn, the place is 3 miles away from me! I wonder if they have a walk up store front?

BTW, I'm only 2 miles from KAC.

+1 for the SLR gas block. Much better than the others I have tried.

I have SLR and Syrac adjustable gas blocks. They both work VERY well, with the same sort of detented settings. The one thing about the Syrac block is that you have to push the unlocking plunger and hold it in while you adjust the block (two hand adjustment). The SLR design uses no plunger (one hand adjustment).

So the SLR just uses the detent to secure the setting? How many "clicks" are there per revolution and how many revolutions between off and wide open?

Yes. The SLR just uses the detent (which seems to be a very positive click). 12 clicks total, 3 clicks per full turn, 4 full turns from off to wide open.

The Syrac is very similar.

Why doesn't anyone make one like these that don't require a tool to adjust? Something like the newer RA XCR or Colt Competition Rifle?

Here are some pics showing how simple the SLR gas block is to adjust.

I'm not in love with 2 handed adjustments. But I agree, I'm shocked there isn't a tool-less option. Something much like a low profile switch block
