I saw they are out of the 16in non threaded. (Don't ask why I was looking) Romeo5 and a 3x. Romeo looks good through the magnafier

First of the $49.00 Sig barrel builds pretty much complete, maybe get on the mill this weekend and fishgill one of the barrels. Aero Precision upper and gen2 lower, Toolcraft BCG, millspec FCG, Danial Defense pistol grip, ebay guard, JBO $9.00 gas block. Have a Sig Romeo 5 coming tomorrow. Also looked at the Holosun, they were on several platforms at triggercon as well, maybe the next budget build.

Yes it is. Oak is at the Nationals next couple weeks so no tube till then anyway, gives me a chance to double check. What I'll try is installing the gas block and the midlength tube, and mark it inside the receiver. See what I get that way. Thanks for the input.

Those shortened bullets are a drag, had a few while working the bugs out myself. On the factory lawman ammo, never happened and I had a hell of a time pulling a bullet just to see what powder / charge, like they are glued in. Couldn't do it with the collet die puller, had to slam it out with the kinetic puller. I usually spray a little lube in the case feeder after dumping in a pile of brass but stopped doing that with the 40. Really need clean tight neck tension. Examining some of the fired brass after it's cleaned, it has some hits at the mouth as well.

Good looking build, but I was talking tube. Thanks.

Rotation The 3 BCGs I tried starting with the gas key lined up with the alignment pin on the barrel extension, bolt extended. Bolt went in and rotated to locked position. While applying pressure I could rotate the BCG a little bit either direction but not 360. That seems good, no? I assembled the 308 barrel with upper receiver and bolt closes and rotates to locked position. I dont have a 308 headspace gauge but I do have a progressive set of dummies ranging from min to a few thou over max in my case gauge I may try them next but I see no problem with the AM10bolt, or either the 223 bolts. The only issue I can see is maybe dropping the BCG on a already chambered round and the pin prevents the extractor from opening up to clear the rim, further testing needed!

I'm thinking 49 bucks to practice milling Fishgill and blowhole comps and brakes is cheap schooling. Enough to convince myself to get another. Screw it up and it's a pistol barrel or pin a real comp on it.

Loaded some Berrys round nose 180s last night, manually cycled a couple mags through fast and hard. Get smilly faces on the top of the rounds where they hit the top of the chamber before they bounce in. Flipped them all over and did it again. Soft bullets for sure but I'm thinking maybe need the feed ramp on the top of the chamber, don't think the bottom is the problem with good mags. Like to find some real jacketed bullets that don't cost an arm and a leg. My other 2 rounds are XTP 155 and Xtreme 180s, plus a few of the lawman 155 left. The harder bullets in the cheap mags seem to work well, and having good luck with the glock factory mags also. Last thing on mags, don't get too aggressive on the hard stop on the left side, if you don't have to slam them hard you have taken too much off. Take a look at stern defense or torkmag website I think that's where I found some filing techniques Mine are running very reliably

Down to 8 of the non-threaded 223's.

Yes, I guess that was my point, it wasn't done to decommission the barrel...

One more, why not...

Also, looking at the hole opposite, it has bluing and cosmaline in it so my guess is not drilled after the fact.

Must be some other reason they are going for dirt cheap. Maybe buy a couple more just for safe ballast

What he said. Both the Toolcraft and the JBO special went in and rotated properly with the pin in the 223 barrel. Located dead center over the extractor. Took the bcg out of the Anderson AM10 because I haven't got one yet for the 308 barrel yet operated fine.

I noticed the pin in my 308 barrel as well, didn't notice it in the 223 barrels, have to check again. As I've said before, nothing a hack with a few tools can't overcome

49 dollar barrel is better then starting with a roll pin... You are way ahead of the game. a 4" muzzle device will put you right at 16. I found a 4-1/2" steel, weighs about 10 lbs. Think I'm going to chuck it in the lathe and put it on a diet.

I like the Geissele, but I'm thinking adjustable. I have the tech to pin any block if I need to. I mocked up the 12-1/16 tube in the upper assembly, 7/8" long, so need a 11-3/16 tube to hit dead center of the receiver cutout. Other option is to move the hole back, the gas block would block the original hole while it gummed up with carbon, or I could drill/ tap a set screw into it. Thinking the custom tube is the easiest option.

Quick detatch handguards seem to be the rave, Faxxon is replacing their pinned/welded 14.5/16in with one that looks to be machined right into the barrel, kinda like what I was thinking of doing with the Sig barrel.

Went up to triggercon this morning, lots of good vendors. Aero Precision to Zev. Really liked the CMC and JP EZ, the JP comes with a short throw ambi safety and anti walk pins. Vendor thought they were going for 160 or so but they were not selling any there. Looks like a $189.00 or so online. Pretty nice trigger, good price with the safety and pins. Everyone needs a suppressed Barrett...

Looking for a 10 in round floating guard and a .75" gass block that clears inside diameter. Lots of options in the 223/556 size, Not finding much for the 308. Need about 1.75"-1.8" ID to clear most of the low pro blocks. Ideas?

I waited till I was back at the office computer and opened it anyway. No ill effects, other thdtr ther ft vit v#$ NHTSA .

Oh, man... Just stumbled on to an oops kit, that should get 3 or 4 builds going...

Hard to beat a roll pin. We're not worthy

Digging through the parts bin, came across a 12-1/16" gass tube. Primary Arms has low pro gas blocks on sale for 9 bucks. Good to go, right?
