AR-15 BS Thread

dont waste your money on removable stuff, you'll have to re-zero it everytime. but, i do think they are okay for reddots (like the eotech exps-3) since the dot is as big as any movement you'll have on it so you'll never notice it.
just my 2cents.

 

awesome deal, i just paid 550 for mine

 

Agreed - good deal.

 

Damn if only I had more rifles to put all these things on

 

X2. I wish I had not gotten the removal PEPR mount but gotten the standard one instead. I never plan to remove the scope from the rifle so I could have saved a few bucks.

 

same here, i was looking at the exps-2 for 520, but by the time i paid shipping, it was the same price as the expos-3 that had free shipping.

 

It addresses half of the short barrel's problems. It'll soften the gas pulse each round, though it doesn't take care of the dwell time,
which is the distance from gas port to muzzle. Then it all comes down to port size. If I remember correctly a 7.5" with pistol gas
system is almost half the amount of dwell time as a 20" with rifle gas system. Less time for the action to receive gas, so it needs to be opened
up just enough to run reliably on low pressure ammo, ie store bought .223. Then there's buffer sizes, adds another variable.

More than I planned on writing, maybe someone else can benefit or be further confused.

 

Would appreciate any expertise for a PDW build

I spent a good amount of time browsing phase 5... wanted the pistol sling mount as it is clean and low pro, and also was checking the pigtail tubes. Definitely want to do it right the first time.

 

If you ask me and many others I know the pig tail is a waste of time and money.

I have several 7-10" and just run a pistol tube and carbine tube on those that I can.
The trick is in the gas port hole and makeing sure that they port is in line with the gas block.
At first years back most people and barrel shops were just cutting down barrels and redrilling a gas port.
Now that people are working up from the start as a pistol barrel looking a 7-10" then they have the trick down.

The only time you will run into a problem now for the most part on a good barrel is some are made to run with a can that adds to the back pressure.
It may not run SubS loads with out a can on it but will in most run SS.

As was stated it all has to do with the distance between the gas port and the end of the barrel to give enough pressure going back in the gast tube long enough to unlock the bolt.
As the barrel/port distance gets shorter then you need to open up the port to get more gas and a faster clip. Then you can add a heavy buffer to counter the speed if that comes a problem.

This is one thing that makes the 300 blackout shine, there are so many loads out there that you can make anything work just from changing the bullet weight or load.
I'm loading 110 grn to 230 grn bullets in them now.
For 8" 10" 16" and I think I have a 18", can't remember if I ever built it up and shot it. Too many to keep up with.

Wow, is that really a 12+ year old thread on AR15.com. Regardless of what you may read on a 12+ year old thread on a forum, Wes is one of the most respected AR upper builders in the business. There are not too many custom builders that have custom barrels from Noveske made for their use and / or work with Taran Butler on the design and manufacture of products.

I personally know that Wes builds many uppers for some very interesting people that do very interesting things with their rifles in the real world.

If you want to research Wes and his work - I am sure you can find many an internet thread filled with raving reviews...or you can talk to people who actually use his rifles in the real world...I am sure you can find both.

I have three rifles / uppers from Wes, a MK18, SPR MK12 MOD 1, and my 3-Gun rifle with a 14.5" pinned and welded Surefire and a KAC URX rail. He is currently building me a suppressed 10.5" only upper with a Seekins rail to swallow my TB223A.

They're all sub-MOA guns and they all run like magic.

I finally have some of the harder to get parts in. Some LPKs, carriers and put some Geissele triggers, BAD ambi safety's, gunfighter charging handles on sale as well.
IronworksTactical.com.

 

:Woot:

You see I carry 80% now?!?!

 

A) You can call Noveske and they will ship you all the barrels you can afford. I know for a fact though that they will NOT deviate from their design spec. PacNor is most likely where Wes is getting barrels from (That's where Noveske gets their blanks) and is a known GA Precision supplier... When I do a Stainless upper, I use Noveske barrels, but there's nothing really super special about them, I mostly buy them because they include a gas block, and I like talking to Sheri on the phone.

B) There's really no such thing as a custom AR builder. It's more like a lego set than anything. I have over a dozen "custom" ARs, but it's more of picking parts out of a catalog than hand fitting each piece such as a 1911. No one has really changed an important design element on the AR platform since it's inception. The only real recent novelties are ambi lowers, but the only people that have that right is KAC.

C) Sub MOA AR eh? I guess I'll have to take your word for it. A combat AR won't ever be sub MOA (And usually not even 1 or 2 MOA), and these guys shooting service rifle comps, you really don't want to tote one of those around for a long time.

D) You don't see many people shooting 3 gun with a 14.5'r... Also a interesting choice in muzzle brake for a competition rifle. I use SJC comps on my weekend rifles, but it's all personal preference.

E) I'm sure Wes builds some nice stuff, but it is an AR we are talking about here. There are no less than 500 companies all floating their AR wares out there. The only difference between one and the other is who their friends are. That's where the money is. Get Costa or Haley to finger fiddle one of your ARs and you'll be a millionaire too....

F) My point is simple. If someone has had some bad dealings in the past, there are WAY too many other places to get things in the AR world. ARs aren't like 1911s where the market is tight and there's not a lot of whizbang go-fast goodies that market to Joe Airsofter, so there's no reason to deal with anyone difficult, or wait on someone 6 months for anything.

G) I'm really glad you like your ARs. You should consider building your own. There's really nothing magical about assembling one.

 

100% correct

 

This. If you've tackled legos and have $100 sitting around, you can buy all the tools to build an AR and feel like a boss. I've built maybe 10? Lots of folks have built 100.

 

1. is your inventory real time?
2. eta on firing pins? cam pins?

 

Any opinions on Adams Arms? It looks like a pretty nice complete upper. The handguard is tidy and reviews I read were positive. There was also a samson handguard that looked nice and like a clean finish.



And the lower I am going to try to get a cerakote finish close to my Tacoma Magnetic Gray. Plenty of tools abounds, just want to have a decent firing PDW out of an 80%. Nice to see LPKs finally in stock many places again. I was thinking JP trigger. Just want a reliable setup, nothing crazy, with phase 5 pistol buffer tube with swivel sling.

 

My 8" SBR runs 100% no need for silly gas tubes

 

Yep my short barrels run also...
