Adjustable Gas Block

I was thinking about trying an adjustable gas block for my 20 practical. I would like to know what are the benefits to using one? I have read that you can tune it to just make the bolt lock back on an empty mag, and it will greatly reduce recoil and help to remain on target for follow up shots. Any thoughts?
 
I wouldn't say they greatly reduce the recoil but there is some effect for sure. Lowering the BCG velocity knocks it down somewhat. As a plus the bolt status locked for that little extra time and will cut down on some of the swipes etc from loads when you are running top pressures. On some powders this lets you use those that would be badly over gassed causing unreliable feeding etc.

I have one on my Coyote AR. I set the gas screw while sitting at the bench, so the cartridges would land just about 3 ft. away. Very soft recoil for those follow up shots. Problem was, that in the offhand position while standing, the bolt wouldn't lock back or even go far enough to pickup the next round. Just saying, make sure you adjust it for function while shooting offhand/standing.
 
I just found an Anderson Manf. adjustable that says it has a 20 position detent that will stay in place without loctite. Also it adjust from the front of the handguard instead of from the side or the rear like some do. It is a set screw type and I had wanted a clamp on, but for half the cost of the SLR I will give it a try.
 
The BTE is a clamp on. The micro is made from stainless, it's also under $50.00 If you are wanting a low profile block it has to adjust from the side. The front adjusting blocks have the gas tube raised for the adjustment screw to have clearance.
 
I use Syrac adjustable gas blocks. The adjustable gas block is the best after market add on made to help reduce recoil other then a brake.

Trust me it helps a bunch. I would say 99% of AR's are over gasses to make sure they cycle.

The SLR adjust from the front and is not as tall as the BTE the SLR is 1.36 and the BTE is 1.4 something so you can get an adjustable gas block and still be low profile and adjust from the front which is easier to use.

I can buy 2 BTE's and have enough left to buy some ammo, for what SLR wants for one gas block. Funny thing is they do exactly the same job and adjust exactly the same way. They are also made from the same material. ( Stainless steel )
I wonder why SLR wants so much for theirs?

They are different the SLR adjust from the front for one and is low profile they are built different you don't have to use loc tite or rtv on the SLR and the set screw will not move plus a better designed in my opinion but to each there own.

That is like asking why someone would pay $300 for a stainless barrel from one maker when he can buy a cheaper barrel for $100 from another there made from the samething so they have to be the same. Some of the price would be for the development put into making something different as you very well know about you build good barrel's.

Not really, You pay for what you get when you buy a barrel. Cheap barrels typically don't shoot well. But were talking about gas blocks. There is no reason that a SLR should cost what it does. The engineering that went into them is the same as every other gas block on the market. No more and no less. They do exactly the same job as any other gas block.

SLR

diagram on there website says they are 1.4 tall.

SLR instructions

I for one dont think a better design consists of extra work or extra steps for maintenance.

So what if I put a small drop of blue loctite on my set screw. I can still adjust it whenever I want to and it does not need more locktite applied. Besides that, once it is set I have found zero need to change it from that setting. Not to mention the price tag. We are talking about a chunk of metal that distributes gas from one tube into another.

I can understand spending extra money on a trigger, barrel, rings etc. With a gas block you are not gaining anything for the extra money.

Yes your wright the set screw SLR is 1.36 the clamp on is 1.4 and the clamp on BTE is 1.41 so still smaller. My main point was that he stated that you have to have a side adjustable gas block to get a low profile gas block NOT TRUE.
