Adjustable Gas Block - Need Recommendations

[Okie_Poke]

I have the clamp on SLR adjustable gas block under an M-LOK hand guard. I can reach the adjuster with a longer, standard end allen key even with my TBAC Ultra installed (a ball end would be a little nicer). The gas block is a snug fit under the hand guard. So much so, that I cannot install any M-LOK accessories in a couple of slots on the bottom. The clamp to hand guard clearance is about 0.055", maybe a smidge less clearance to the clamp screws. It's a dia 1.36" ID PSA hand guard.

Thank you.

The best adj gas block for high end builds is the Rifle Speed, it has no equal.

The caveat is it is expensive, requires a straight gas tube and requires a hand guard of adequate I.D. and length for proper fit..

The Rifle Speed needs no tools to adjust and uses different adjuster plungers lengths for different gas adjustment needs.. I custom fit my adjuster plunger by shortening it to the perfect length..I also added a second adjustment spring for extra resistance for adjustment..

The Rifle Speed can be easily pinned if desired.

Every adj gas block needs maintenance to prevent the adjuster from carbon freeze. The Rifle Speed is very easy to maintain, service and replace parts..

I had not heard of this one previously (I'm new to adjustable gas blocks) but am looking into it. It's very interesting. I just need to figure out if it will work with what I'm trying to do.

Probably the most important thing you need to determine is if this a set and forget setup. Do you plan on changing loads frequently or shooting suppressed and unsuppressed? If you will make making changes frequently I would go with the superlative or buy once and cry once with rifle speed. If you are going to only shoot suppressed with the same ammo, then any decent adjustable gas block will do. I, nor my counterparts, have ever used an adjustable carrier so I cannot speak to that. Alternatively, buy a flow through suppressor and not worry about any of it.

I currently run a few different 123 grain bullets on top of CFE 223, but they are all basically the same load. And I run one of them way more than the others, so I think of myself as only really shooting one load in my current Grendel. I am hoping the new barrel will like similar loads as the old barrel, though I'll of course have to do some load work up. I plan to find loads for 123 match bullets and SSTs, barrel willing, and just shoot those for the most part. However, I do plan to switch back and forth between suppressed and not suppressed. One of the matches I shoot with my Grendel doesn't allow suppressors or muzzle brakes (only flash hiders). The other match allows suppressors, and I've grown fond of shooting suppressed whenever possible with my bolt guns when hunting or just shooting at the range. I'd like to think that will extend to this build.

Question: what about the superlative makes it better than some others for more frequent changes? I can see with the riflespeed you just turn it. But why would the superlative be better than, for example, the Aero or SLR (or is it)? Thank you!
