I posted that article here in the Cleaning & Maintenance section .

The 18" Hybrid SS Nitrated barrel from Criterion I used for a built ,was a very , very good shooter & cleaned up easy . Some don't like the Stainless look , so the Nitrated is a plus for those who don't like the Bling . I only have one Barrel on AR's that is not SS , a Nitrated one from Brownells . I have one other Barrel that is SS & Parkerized , its a 24" HB Ultra Match from Olympic Arms, pretty sure its not coated on the inside , but the Nitrated is . Jury is still out on Nitrated Barrels , the Chrome lined has been around for a very long time & has a proven track record , but the Nitrated /Salt bath type Barrels are looking like they have a very good future . The one Barrel I have thats not stainless is a good shooter , but time will tell . The 24" Parkerized Barrel still has a great finish on it & it & it was built in the late seventies ! I will build with another Nitrated Barrel & the idea of a Nitrated SS Barrel seems like a good idea , best of both worlds . I do doubt we will see a Chrome lined, Nitrated, SS barrel though

That Stock set up has had issues with other Rifles here before .

Double post

OK , I give up , what am I supposed to see

Or just disassemble & clean more often when using suppressed , if the above doesn't work . Trials & tribulations of running suppressed semi or full auto Firearms .

How about some info on this new rifle or build ? Could be light powered ammo , but has enough to strip the next round . Is the Bolt catch catching on the Bolt Face , when you lack the BCG back ? As above , Soft tip exposed lead Bullets do not feed well in a lot of AR type rifle , some do , some don't , like them . And yes , the Buffer Spring can be wrong or too much spring tension .

Geez !

Since that was a comment from the Article , it sounds just like the debate that has went on for decades ! ( & he is a 45 auto fan !) The 45 acp caliber is a one shot man Killer ! How many times have I read tor heard that statement . Its all about shot placement , period .

Pretty much rules out the Bolt components , to a certain extent . The Photo seems to show , as has been said , slow BCG travel or an Ejector or Extractor issue . -Too slow of BCG travel will not have the quick change of direction to help eject the fired case or Ejector Spring is weak or compromised by fouling or both. -Extractor is stiff or locked in one position or too stiff of Spring pressure . - Lubricant used ,not up to job or not enough of it . - Loose Carrier Key Screws or Key not seated & leaking .( Suppressors seem to pronounce this condition ) -1500-2000 round count could have a prematurely worn component , Chamber throat erosion ? What caliber ? Have you been using this rifle as a single shot on purpose or is it because it never ran correctly ? Have you completely disassembled the Bolt components & cleaned & lubed ? Have you checked Gas Ring tension ? A lot of questions , but this is like a Detective story , since we cant put our grubby paws on it or see the rifle . There Tubb's Spring should work much better then a OEM one . Running any Rifle Suppressed is going to do all kinds of strange things to an action & one is heavy Fouling in places you don't normally see that kind of Fouling. I think you will find a Gas issue in some form & that could also be from heavy fouling .Keep us informed on your progress .

Interesting piece on what is the best handgun caliber for defensive use . https://gundigest.com/handguns/concealed-carry/best-caliber-self-defense-concealed-carry-ammo

I wonder where the got the Links for that ammo ( 22mag or 22 LR ? ) They make the Links ? Pretty cool show piece .

Herre is one persons view on this . AR-15, HUNTING, RIFLES HUNTING: .300 AAC BLACKOUT FOR DEER? DECEMBER 28, 2017 GLEN ZEDIKER 1 COMMENT This is a big question around the whitetail woods: how well can the AR-15 serve as a viable hunting rifle when chambered for this round? Here’s one answer… Read on! SOURCE: NRA Publications, American Hunter by Philip Massaro The AR-15 platform has been modified and fiddled with for quite a while, and has its own series of cartridges designed specifically to function within the parameters of the rifle. The 6.8 SPC, the .458 SOCOM, the .50 Beowulf — all were built to give the AR-15 a different level of performance than the standard 5.56 NATO/.223 Rem. There is also no doubt that .30-caliber cartridges are, have been, and probably will remain America’s favorite. So many cartridges have been modified to hold .30-caliber bullets that I have almost lost count. The .300 AAC Blackout is the cartridge built to function in the AR-15 platform, and with its design comes a different mindset, as the cartridge is called upon to fill a special role. As a hunting cartridge, the .300 BLK certainly doesn’t look like one of the usual suspects: it is a stubby little guy, definitely lacking the look of a long-range cartridge. That’s fine, because the Blackout was never designed to fulfill that role. Perhaps a bit of history is warranted: The Blackout’s roots are spread in the soil of the U.S. Military, which was looking for a round that would give better sub-sonic capabilities than their suppressed 9mm carbines, especially for close-in work. With some modification of a wildcat cartridge — namely the .300 Whisper — the .300 Blackout was delivered by Advanced Armament Corporation. The case itself can trace its roots all way back to the .222 Rem., through the .221 Fireball case also formed from that platform. It was designed to fit in a standard 5.56mm AR-15 magazine in double-stack configuration, yet use the long 220-grain .308 caliber bullets for subsonic performance. The Blackout did just that — pushing those 220-grain slugs at 1010 fps — but also did very well with the lighter bullets. That short case will push 125- and 130-grain bullets to a muzzle velocity of around 2200 fps — certainly no speed demon, but enough to get the job done on military targets. It functions perfectly through the AR platform, with one caveat: any ammunition that uses the sleeker-ogive bullets will actually chamber in the .223/5.56mm rifles, and that can pose one helluva problem should the ammo be confused. Please keep them separated! In the the deer woods, the .300 AAC is an acceptable choice. If ranges are kept around 100 yards — much like the .30/30 WCF — things should go right for you. Were I using a Blackout on a deer hunt, I’d most definitely choose a premium hunting bullet in the 125- to 135-grain range, as they’ll produce the proper terminal ballistics. Those heavy 220-grain slugs are simply moving too slowly to give reliable expansion, and will more than likely whistle on through like a solid, resulting in a wounded or lost animal. No one wants that. Author believes that, loaded with a suitable bullet, the .300 Blackout is suitable for use as an effective deer cartridge, as much so as are others with similar ballistics, such as .30/30 WCF. Ammunition choices are pretty broad now. As said, you’ll want to keep your hunting distances within reason, and choose a bullet that will expand reliably at the furthest distance you expect to take an animal with the Blackout — the range where that bullet will slow down. I’m not one of those who gets hung up on energy figures — where the commonly accepted figure of 1,000 ft.-lbs. to kill a deer came from, I don’t know — but you definitely need reliable expansion in order to kill effectively. Looking at just a few, Hornady loads the 135-grain FTX bullet at a muzzle velocity of 2,085 fps, and this will make a great hunting round. They also load their 110-grain GMX — an all-copper, polymer-tipped bullet — that will also get the job done well, again, providing you use it within reasonable ranges. Barnes builds their VOR-TX Blackout ammo around the 120-grain monometal TAC-TX bullet; Barnes worked very hard to deliver a bullet that is plenty accurate and yet gives good expansion and penetration. The whitetail deer has suffered from guinea-pig status; I know hunters who seriously use calibers ranging from .17 Rem. all the way up to the .450 No.2 Nitro Express to make their venison, with varying levels of success. The whitetail is so prolific that, like feral hogs, sportsman tend to experiment with varying calibers and bullet weights. A good bullet, like that GMX or TAC-TX, at the lighter .30-caliber weights, will get the job done, and that’s been pretty well proven. Considering the Blackout’s trajectory, you’ll want to limit the range to 100 or 125 yards. To obtain a 200-yard zero with the Hornady FTX load, you’ll need to be 5 inches high at 100, which is a bit drastic. Perhaps a 100-yard zero, or 1 inch high at 100, where you’d be in vitals at 125 yards, makes more sense. So, is the Blackout the perfect deer cartridge? It’s no .308 Win., but I that within 100 yards it’s a better choice than any .22-caliber centerfire. The choice is up to you, but if I were handed an accurate Blackout for a hunt in the northeast woods, I wouldn’t hesitate to use it, provided it was loaded with a good, sensible bullet.

If you go by that Blue Print , there is nothing wrong or out of spec with this barrels Port size ,Blue Print for a rifle gas 18" bbl., OP has a 20" . I trust Wilson Combat , I have several of their Barrels ( 5.56 & 300 BLK ) & they run fine . Maybe their are other issues with this Gas system , Gas Block gas passage, within the Block , not restricted & Block aligned correctly . How far does the gas Tube protrude into the Upper Receiver ( photo ) ?

Thats what I paid for the Socom , Looked around a couple days ago & the prices were all over the place & mostly out of stock . I emailed SA to see if they have that color available for just the stock , I like it also & the Black , really doesn't matter to me , but if the FDE Stock is reasonable , I will pick one up , maybe even keep the Black Upper HG with it . Maybe .

Or send your Barrel & Bolt to Faxon for them to test .

Forster Headspace PDF-2.pdf I think I would find another Bolt to try , but would find PT&G HS gage set to use with your Bolt first .

98 I think the quote you posted is from Faxon Barrels ( I think ) & my take was his testing was posted above , that the Bolt did not close on the Field Gage .

I thought that was a tip for your WaterPick Use before brushing your teeth .

Criterion I thought that was the Manufacturer that had the secret Port sizes , I wasn't sure . I think we all gave them , "what for " about that in your thread , hope they read it .
