Copy that. It'll be on the bench for a little while, getting out for some hunting. Dragging the trailer down to camp this weekend.

Correct. I'm using the armalite carbine extension kit, so buffer is 5.4 oz as well.

Going back and forth from messaging Concretus and this thread, he was running rifle length extension tube, 308 rifle buffer, tubbs 308 spring, superlative adjustable gas block.

I searched gas port thread, got 100 pages of everything but that. Like to check it out, point me in the right direction?

it reportedly cycled several different types of ammo both factory and reloads. Don't know what spring/ buffer combo. We are going with an adjustable block anyway and the armalite extension/ spring/ buffer so I'm thinking just go to .080 diameter to start and do my adjusting without several trips between the drill press and the range. That drill press part is stressful! Hunting season starting so probably won't be going to the range for a while.

1:8 18"

18" BA, the one I bought from Concretus a couple of months back.

Going to town on the 6.5 Creedmoor build, checked the gas port, .062 no go .059 go. .875 journal. Mid length gas. Is that the correct port size? Seems small, but nothing to compare to. Interesting factoid, the BA barrel uses the 11-3/4" tube, not the 12-1/16. Assembled with 12-1/16"tube, visually way past center of cam cutout, and confirmed bolt will not close. Didn't have a 11-3/4"" laying around.

.0995, wasn't it? So what I am hearing we may have a good running 308 with a 7" extension and a 2.5" buffer. Kind of where I wanted to go with my next 12-1/2" pistol build using the Tailhook Mod 2 brace.

Do a lot of grinding and stuffing, beer brats, summer sausage, breakfast sausage, chorizo, landjagger, lean beef burger and bacon burgers-- 15 lbs lean beef trimmings, 5 lbs of bacon, grind together and run through the patty press. Freeze in pairs, quick and tasty on the Weber.

Tuna, Pepper Jelly, some wild meat, few other odds and ends. Seems like the lids are costing more and more every year. Never thought of taking pictures!

Uber and Taxi drivers. Not kidding.

R Lee Ermey! What is your major malfunction?

Didn't like the look/ feel/ weight of the ebay hand guard on the sig pistol build, replaced it with a M-lock from AR15handguard.com. Sent me a high profile first but very good customer service, had a return label within a few hrs of reporting the issue, had the correct one back to me a few days later. Good communication. Anyway, got it on tonight, and one of the holes lines up perfectly with the gas block adjustment screw. (The lucky part)

R Lee Emery!

I didn't shoot the 308 before opening it up, but I did the 223's. .078 (5/64") seems good for both. Put an adjustable on the 308, low price/profiles on the 223's, all running great. Solid carbide 5/64" end mill just showed up, have a couple more to do when I get energetic.

how about close ups of the area milled?

After the last round of cleaning I found an extra extractor spring on the table. More concerning also the little one that goes in a 308 extractor. Pulled the bolts out of several AR's, the one in the 458S was in backwards. Flipped it over, got it to snap into the extractor. Sent Tony an email asking him if he uses the little spring inside, or the insert. Put everything back together and back in the safes. Tony emailed me back and said nothing except the spring, and he puts them in backwards compared to AR 15's. Went through the 458 and 2 308's again, flipped the one in the 458, found the 308 bolt missing the little spring, but noticed something funny about the firing pin in the 458. Had a 308 pin in it. Pulled a AR15 pin out of my field kit, swapped it out. Now my field kit has 2 spare .308 pins and no AR15 pins. I would swear I always carried one of each. Pulled and checked the 308's, they have the correct firing pins. I'm getting pretty good at this. Just wonder who's kit has 2 AR15 pins and no 308 pins and where the extra extractor spring came from.

I went with the Aim Sport on one of my AR15 builds, good quality good price fairly light weight. Thinking about using one like this on my next large frame build. https://www.primaryarms.com/aimsports-ar10-15in-mlok-dpms-high-handguard-blk-mtm15h308 One thing to consider though, the slots on the bottom do not go down the center line so might have to use side mount bi-pod legs. Maybe also check out https://www.ar15handguard.com/ Sam Pan is a character but he has good customer service/ returns/ replacements.

Hello, Rabid Dog Special charging handle? Lots of pictures!

Yes, read that one. If a public pretender can get you off that's a pretty good indication of the merits. PS I measured correctly used a framing square. With the Armalite extension the SBA is 13-3/4"+

I have a set of numbered bits, get last go and first no go, close enough. if you had good eyes you could probably get it with a dial or digital caliper.

It must be true, found it on the internet. SB Tactical's website: HOW LOP IS MEASURED Length of Pull, or LOP, is the straight line distance measured from the middle of the face of the trigger to the end of the gun’s stock or brace in it’s longest configuration. The ATF has advised that a braced pistol with an LOP in excess of 13.5” may constitute a re-design of the host pistol and subject the pistol to restrictions under the National Firearms Act. As I get occasional visits from LEO for frightening the neighbors, loud explosions, etc don't want to run afoul on this point if I can help it.

After looking at it the other day I was trying to come up with a combo that the Aero M5 extension kit would work in, buffer to short for ar15 and to light for a 308. I still can't believe AP runs that in their 308 builds. I started out posting here when my Anderson AM 10 was built the same way. That dog just don't hunt.
