Don't think the gas block I want exists.

I would like a low profile, staked, multi position gas block, but it looks like I can't have all that.

Adjustable or fixed?
Since I have to be difficult I run hand loads with a silencer. So adjustable, obviously.

There's several ways to adjust the gas system. A screw is most common. But I like the aftermarket 4 position gas block adjustment on my sagia S12. My AR15 ammo is almost as diverse as shot gun ammo. So being able to know the setting for factory ammo and the setting for 223 start load ammo I reloaded would be nice and not having to hunt for the setting like on a screw adjustable block would be nice.

There's 3 ways to attach them.
Set screwed, hands down the worst option, when the set screws come loose you're screwed and they always do.
Clamp on, a less worse option than set screw. The mini14 gas block is clamp on and I never had one come loose so it can't suck that much.
Staked, the way St. Stoner intended. What's the big deal, it's not that difficult to stake an A-pillar. If you can hit your thumb with a hammer you can stake a gas block. It seems everyone avoids staking a gas block like the plague.

The closest I can get and keep staked would be an A-pillar cut it way down, with a drilled and tapped gas screw.

But if I give up on staked and will accept clamp on it looks like strike industries makes a collar click adjustable clamp on gas block. Appears to be the least worst, most best option.
But the way it clamps on kind of sucks.
 
All I've ever used are set screws or pins, I do loctite though screws and the gas block on, I've never had any of them come loose..... Heck, after a couple thousand rounds are almost impossible to get loose.....

If you're absolutely insistent on not using set screws though, I think the clampons are about your only option.... I'm pretty sure I've seen some other ones besides the strike.... I don't know if there were multi-position though, think they were just screws.

I've never seen a pin on adjustable.... At least I don't think I have
 
JP low profile detent adjustable block. Two piece, stake the screws if you want. Drill it for a roll pin or drill and ream for a taper pin if you want. Count your clicks from full closed to hit your suppressed vs noisy - or just pay attention to how many turns you need between the two.
 
. . . low profile, staked, multi position gas block, but it looks like I can't have all that.
Give up on pinned (staking is done to screws or pins), and get a set-screw block, and do a good job attaching it.

The advantage of taper pins is very low cost in a production environment. Countersink the screw tips into the barrel a smidge, and stake the set screws. . . I'll bet the be result is as secure as a taper pinned block.
