Pro grip all day - I add extra 90% alcohol to it for the consistency I like

For those that have purchased the Lok brass magwell for your S2 or other, how are those things looking so far as wear goes, after several months of use? Just curious if they get super beat up quick.

Only 1500 rounds or so into 9 major but am loading the following for my czechmate: 124gr RMR MPRS 7.2gn WAC 1.15 OAL Have a pound of AA7 that I'll try later in the year but so far, happy with how this is running the gun.

Yeah, for future reference, they are 4-40 thread set screws. I had ordered both 48 and 40 TPI from McMaster to sort this out haha. P/N 94115A103 is a 10 pack of 1/8'' alloy steel nylon-tip screws P/N 91375A717 is a 50 pack of 1/8'' alloy steel cup-points

Anyone know the thread pitch / thread size for MBX basepads? Lost one and they don't have it on the site and haven't responded to email or phone.

@BRuss are those the short gridloks with the sebo magwell in your original post pic?

What riser you running?

Meshes with how I was going to approach the question so appreciate the confirmation.

Curious what recoil spring y'all are running with an optic mounted on the slide. Does it change the equation or keep it the same as if it weren't there?

Yeah, completely unloaded to a target 7 yards away is round about what I was wondering... Appreciate it! @SGT_Schultz, to a loaded chamber is also an interesting metric and makes sense to be curious about.

What's a strong target par for an unloaded barrel start to first shot for CO/Prod?

Turns out there was too much ano on the threads and they needed to be cleaned up @RaylanGivens. Took it to a local smith who put a tap on the receiver and removed some ano from some of the threads and voila, buffer fit like a glove! Mystery solved.

Putting together a FM9 lower and started to install a 2A armament AR10 milspec buffer tube. I get about one rotation in and then the two no longer screws in and binds up. I happen to have two brand new buffer assemblies and both behave the exact same way. I'm wondering if anyone is encountered this with these lowers? Also, for good measure, I tried installing the tube into an Aero lower that I have and they install fine.

Can close the case here. It was a pressure issue.

Yes is get a hundredth or so of variation in the mixed brass sampling I am using to load. I am more curious around WHY that induces the failure when I still am well off the lands with both loads. Am I simply getting faster peak pressure on the longer load and seeing a piston effect from the case strong enough that the ejector cannot maintain control?
