Good to know! 👍

I have been using CLP but recently ordered a sample size Cherry Balmz Black Rifle Balm to give it a whirl. I applied it to the bolt, bolt carrier, cam pin, etc… It won’t completely replace oil but applying it in the appropriate places seemed to make both guns cycle much smoother (16” BCM carbine and Aero 16” mid length) This morning I’m applying it to another 5.56 and my .308

That looks like crap, but it would be reassuring to know that it’ll still run even while filthy dirty. It’ll take a couple hours to get it cleaned properly. When you clean it, post up some after pics to show how A-Z works for cleaning. I did a similar torture test to my S&W 625, about 1200 rounds later the carbon build up was dragging on the forcing cone, but it still functioned.

5.56 for popularity/availability 12 Gauge for versatility/availability .45 ACP just because .38 Special for versatility .22 for popularity/versatility I should probably have a 9mm due to the calibers popularity.

Wrong forum

My Aero M5 build was very similar and my experience the first time out netted the same result. Conventional wisdom says that you are under-gassed, which was certainly true in my case. After confirming proper gas tube length, gas key integrity and gas block alignment I enlarged the gas port and swapped the Aero Carbine buffer and spring for a much heavier buffer and spring package from heavybuffers.com based on rock solid advice from the forum's resident experts. More information is necessary if you want the correct advice for your specific combination. Check one of the "waterboarding" threads for what info is required...

Aero uses threaded pins in the bolt catch and forward assist, it’s one of the main reasons they are my go-to manufacturer for uppers and lowers.

Thanks for sharing the link

If I get a third safe my wife will be suspicious…

I spent 3 or 4 hours last weekend reconfiguring the inside of my safe to make room for one more rifle. I'll either have to sell something (not happening) or get a bigger safe if I add another long gun to my modest collection.

14.5” Criterion Core barrel and a BCM BCG...

Absolutely, I should have about .250 to spare. Assuming it meets the legal requirement during mock up, I'll drill for the pin and have a buddy TIG it. Thanks for the heads up though...
