Anyone have any experience with this one? Pro's/Con's???
Was it adjustable enough or was it 1 notch too much/one notch not enough?
How about lock-up or burn out?
Thanks.

Just looking at the design I would think that ring would lock up or get stiff after a bit. The 5 steps are likely enough to cover most situations, but obviously lacks the fine tuning of other designs. Interesting for sure...

i can’t see how the design will allow consistent air pressure to the bolt. Also At 99.00 I would go with Superlative Arms.

Aero Precision just came out with a new adjustable gas block that looks appealing. Looks to have all the features SLR has bit for about $30 less.

Agreed that it looks like it'll bind up after a bit of shooting and fouling. I've yet to hear from anyone who actually used one in person long term though.

I do wish people would quit recommending Superlative gas blocks and their gimmick bleed off function. It's a marvel of marketing, but that's about it.

Hmm. Looks promising. Kinda wonder about the so-called carbon chamber but whatever, like all the others, it will most likely lock up like all the rest. As mentioned elsewhere, maintenance is key.

As for the Superlative ones, I understand the concept however am leery of them.

The one thing I have not seen posted, of all the threads I have read on gas blocks, a couple hundred or so,,,
No one has mentioned weather or not a conventional style GB or a Vent style Gb is more or less forgiving when changing from one ammo to another, ie; 147's to 168 or 175 and back.

My concern is if you are in a "grab-n-go" situation when SHTF and you ran out of your worked up load for your particular rifle and had to grab something you find along the way, will it cycle? Will I have to keep adjusting the GB every time I throw a different round in it???

Forgot to mention, I am running a LR308 w/20" barrel.

That’s more about how you’ve tuned the gas block than what kind of gas block you use. If you’ve really fine tuned the rifle to run just with one full power 308 load, then it may choke if you switch to milder 7.62 loads like M80 ball. If you want to switch around, the answer of course is to tune it for the mildest load you might shoot (I.e. time for M80 and it’ll run everything else too). It’ll be a little over gassed with the hotter loads because that’s the nature of mixing 7.62 and 308, but it should run everything reliably.

Also a heavier mass carrier setup tends to be more forgiving than light weight setups.

Bear in mind the power level of the load is not about bullet weight, but about the amount of energy in the powder charge. You can have a mild 150gr 7.62 mil-surprise load and a fairly hot 150gr 308 commercial load. Moving to 175gr for example is not necessarily hotter just based on bullet weight, and doesn’t necessarily cycle the rifle harder; it may or may not depending on the load.

Cool. Thanks for the info!
