re: Official AR-15 thread

I went with a 8.5" Noveske Stainless for my 300blk. Lots of reports of people getting 12000-15000rds out of them. In an old interview I read, John Noveske said that the proprietary button he uses helps with a more gradual degradation of accuracy so that the groups expand rather than just immediately sending projectiles tumbling. I think he said that his typical stainless group was .5-.6MOA whereas his chrome lined barrels were "sub-MOA". I'm going to get a chrome lined next and compare.

I found the interview and he mentions a run of "extreme duty" barrels that they did out of 17-4 with a RH of 38 he said they sold for $1000 and just tore through tooling so they put it on hold

RIP John

I have seen the interview and I believe it was one from 2005 that was later referenced years later when he was talking to the same guy and mentioned more about his barrels and included that bit about the $1000 barrel. It mentioned a stainless barrel of theirs that was seen at a carbine CQB class 3 separate times in like 6 months and observed by the instructor to not have lost any noticeable accuracy over the 10,000 rounds fire through the classes. I don't exactly recall the details, but that's it in a nutshell.

This could happen because at a CQB class you are likely engaging targets at <100yds. A shot out barrel is one that has had it's throat eroded away such that it can no longer hold the bullet so that is enters the rifling at the correct angle. It is well known in the benchrest community that a barrel can be "shot out" and no longer capable of holding 1 MOA at 600, but still be serviceable and hold MOA at let's say 200. This is because as the barrel's throat erodes it gets to the point where the jacket of the bullet is getting fouled as it enters the rifling. This causes the gases to not evenly surround the bullet as well as well as effect the predicable aerodynamics of the bullet in flight. This can create a barrel that is MOA at 100 yards, but 2 MOA at 600yds. So, if you are doing CQB classes at 100yd an in it could take until the barrel starts sending bullets end over end to realize it is shot out.

If you start with a cheap stainless barrel that has a throat machined with too much tolerance (tolerance is tighest in the throat) due to poor quality control in producing cheap barrels, your barrel could be "shot out" so to speak before you fire a round through it. That's why I questioned the guy on his barrel choice. It didn't make sense to me as a regular AR 'gunning', ride hard, etc. barrel and it didn;t seem like a good choice as a hole puncher either being that the last place you want to skimp on quality on such a rifle.

I also believe Noveske call his barrel a "modified polygonal" rifled barrel. I know he mentioned how close he held the info on his "buttons". From what I understand most true poly barrels, if not all, are CHF. THe gradual widening of groupings before keyholing is a characteristic of button and cut barrels. Poly barrels from what I understand pretty much go to key holing when shot out.

I;ve had some cocktails so pardon me if none of that made sense.

nobody. I ordered from silencershop.com in texas. great service. absolutely fantastic!

I got mine from landry guns..

what brand and caliber?

i was going to get an osprey but they didn't have anymore so i settled on a griffin armament resistance 45. Got it for 589. price on griffin's website is 749! I got a huge discount thankfully. I'm using a lone wolf aftermarket threaded barrel for my G21.

Yeah pretty pumped for January 2017

I alluded to this is another thread, but I plan on doing a quality build in the nearish future. Already have a stripped lower.

Working under the assumption that HillBill wins, what parts should I buy in advance? I fully expect enhanced regulations. Pistol grip? Stock? Magazine release?

You have the part that matters (lower). Any and everything will be scarce if it gets to post Sandyhook levels of demand/hoarding.
ETA: if you're gonna get anything, stock up on mags and ammo

If it's possible for them to ban AR parts like stocks, LPK, bolts, etc then I assume they will.

I would be more worried about trying to find a BCG or LPK with all of the hoarding that will go on if she gets elected. After SH parts were very hard to come by and good parts were almost impossible to find.

Another option is to just buy a complete rifle since they are still cheaper than ever. Working with your assumption that prices will skyrocket you could upgrade pieces as you were able to find them available and sell off your leftovers from you 'basic rifle' fairly easily if there is a true sandy hook style panic.

If you wait for a panic you'll be left paying at least 2x current retail for all the bits and pieces...if you can find them. The time is now while everything is still at rock bottom.
