I would just pony up the extra funds for the Rifle Speed Adjustable Gas Block. Everything else looks like a gimmick compared to this one. Super robust, easy to clean, can't ever see one really wearing out or ever seizing up.

Aero Precision from Bexar Arms for a great price. Comes with extra detent spring and ball plus extended allen wrench for each adjustment from front.

I like SLR adjustable blocks for my suppressed SBRs in 5.56 and 300 BLK. I only shoot them suppressed. SLR sells/has rebuild kits should the spring or other small parts break (I've broken a bunch of gas blocks over the years - the heat kills them eventually).
For a gun that it going to go back and forth between suppressed and unsppressed, I'd get the Rifle Speed. I have one on a 308, but I just finished building it last week and only have a few rounds through it - can't really say much about it yet, other than I think it is built well. |

I’ve got Aero and Superlative AGBs, haven’t had any problems with either.

Superlative arms here on a 6.5cm that runs suppressed and unsuppressed like a champ.

Yeah, I’ll never recommend a SLR adjustable gas block. I had so many issues with them shooting suppressed. I was going through rebuild kits like crazy. They sent a couple to me hoping it would solve my issues, but never did. every couple hundred rounds or so the leafspring would bend outwards causing the adjustment screw to back out. There was a thread on this I started a few years back. I was not the only one with this issue, I think it’s an inherent flaw in the design. gas flows past the adjustment screw, lifting the detent up and bending the spring. I shoot a lot though high volume.

Wow - I've never seen that. I've got two SLR gas blocks and many thousands of rounds through them without a problem with exception of one broken spring (and the gas block still worked).

Does anyone know if the Aero agb is their own design or is it someone else’s design with their name on it?

I run a JP Enterprises AGB on my AR .308. I have the 0.875 block as that was the size necessary for my Rainier Arms Ultra Match barrel. JP makes the same block in 0.750 as well.
It is lower profile than many GB's so fit well under handguards. JP Enterprises Adjustable Clamp On Gas Block AR-15, LR-308 0.875" Inside Diameter Low Profile Stainless Steel Black JP Enterprises Adjustable Clamp On Gas Block AR-15, LR-308 0.750" Inside Diameter Low Profile Stainless Steel Black |

Yeah if you’re just slow firing at the range or plinking, I doubt you’ll ever see an issue. When I go to the range it’s a 6-8hour day of running drills. As I said I think it’s a inherent design flaw. I now look for adjustable gas blocks that have no internal(in the gas area) springs/detents. I want to micro MOA in my fighting rifles, as a sidenote, God, I wish he still made those. But having had my hands on a rifle speed gas block, it looks to be a extremely solid design I’d have no issues using it on a fighting rifle. I have one on my SFAR. |
