I have had a couple SLR gas blocks and they are very nice. If you go with a WOA barrel the gas block will fit extremely tight but once it is installed you will love how well it fits.

I appreciate all the good recommendations. I like the idea of the Innovative Arms upper but I’m running rifle-length gas. I’m giving SLR and Odin a hard look, and paying closer attention to the inside diameters of the billions of good option for free-float tubes out there.
Anybody seen / used these? I’ve used three and they are pretty dang good, esp. for ~ $75. They are well made and simple; heat treated, spring loaded detent for valve position. This one operates via screwdriver, a guy could put a knob on it I reckon. It set screws on but they are soft enough to drill for a crosspin.

I've got several SLRs, they flat out work!
I’m a big fan of the Superlative Arms gas blocks.
Sentry Seven looks like a solid unit, and at that price point it should be. On the issue of detent adjustments vs. infinite linear adjustments is the benefit just that you don't have a securing screw to hold the linear adjustment?...a single step vs. a two step? The detent "count" issue is fine, but it's still a number you have to remember or record for future settings when you change ammo, suppressor, and such. With the linear adjustment you have to remember a "clocking" or rotation number. With a detent system it's how many "clicks". With a linear system it's how much movement on the imaginary clock face or rotations. As far as speed goes, it's definitely quicker on the detent system, but is this really an issue where speed is that important?...maybe a 5 second move with the detent and maybe 20 seconds with the linear? I have one detent adjust gas block and three linear adjust blocks. They all work great. The last adjustable block I bought was a Seekins at about $55. It's linear. It works as well as the higher dollar detent unit I have. I have absolutely no doubt the Sentry is top drawer in its quality, but for you folks here who have one, is it worth twice the price? And really, my question has more to do with detent over linear unless the Sentry has a truly obvious advantage in one of its other features.
Yes. Yes, it is. I wouldn't waste my time with an adjustment screw without the detents because there's nothing to keep them from backing out. The detents hold the adjustment screw in place so that once adjusted, the settings don't change themselves. That alone makes the SLR worth the extra money.
Having detents also means the adjustments are repeatable. This is very important when tuning an AR for best reliable function, especially when trying different combinations of springs & buffers.
The SLR was a reliable gas block until I stripped the the head of the adjuster screw. When I contacted SLR about getting replacement parts, they sent me a new and improved gas block, free of charge. SLR backs their products.
Right to Bear has the SLR Gas blocks for 103.99 after you add it to your cart and choose the option without the gas tube. With gas tube (nitirde) its $110. Good price and i have ordered a bunch from them. Fast shipping and good service
This is an are that I have had quite a bit of experience with lately. I, on a whim, decided to try and adjustable gas block. I went with the Superlative Arms for the fact that since I run suppressed sometimes, they have a bleed off valve. The thing that makes the Superlative so cool is that it can be run as a normal, restrictive block, or, when running a can, and you don’t want ANY excess pressure going into your suppressor, you can run the block as a bleed off. Running it this way allows the excess gas to be vented out the block, and NOT down your barrel into your suppressor. I really like the blocks. They work absolutely as advertised. It has allowed me to get the block adjusted to exactly the point that my rifle functions 100% reliably, but NO excess gas is vented down the barrel. They are made in a way as the adjustment detention is external, thus it will not be carboned up and stick. I have since installed one on every rifle I shoot. I have about 1000 rounds down the pipe on my main gun. I shot it until it was absolutely filthy dirty, with zero malfunctions.
I am a fan, and a big believer now.
