16" or 18" Barrel??

[Boot_Scraper]

I tried the search function but came up empty.

I got a 18" on my PA10 at the moment, which shoots and functions really well (sub moa). However, Faxon has a very tempting deal right now on a 16" and I just can't shake it. I'll use the rifle mostly to deer/hog hunt. Shots will be well under 100yds. Lighter weight and a shorter, handier rifle would suit my needs better but how bad would the muzzle blast be on the 16"? I am running a linear comp btw. Thanks for some opinions.

  16"

16, no question about it... especially with a Faxon. I just called Faxon today to put in an order for a "few" Faxon barrels.

Very compelling argument. I love your conviction!! 

Well just when I thought I was done.  My budget build is not really following it's original path. Thanks to the fine folks (I blame ya'll wholeheartedly) on this forum I gotta sexy new 16" Faxon pipe and an adjustable gas block in the US Postal system. 

Thanks @Robocop1051 

Anybody want a sweet deal on an 18" middy"?

....or you could just just build another one.  Your call. We won't judge.

Fortunately guns aren't like wives and girlfriends. They don't get all jealous when you have more than one hanging around. In fact, I'm pretty sure they enjoy company.

That's why we prefer to spend more time with them.

[DNP]

Oh I know...I can hang out with my guns for hours...the wife on the other hand...

[DNP]

I guess she's fun for a few minutes here and there.  And maybe a little more over there...

I meant with the guns dude. Hell, that's why I got rid of the wife almost 20 years ago.

And now.......I'm the hermit (when not working).

If those aero sets come up again for $185, I probably will.

Yes muzzle blast will be more then your 18".... I'm not sure how much, but trust your instincts, the .308 has a lot of volume of propellant gas.... the linear comp will help as much as possible.

And as long as the barrels profile has as much mass as possible towards the receiver, it will be much more nimble / balanced feeling.

As for the "fever" in respect for AR parts... it is .. well terminal... Lol
I looked at the barrel, and it is a bargin.... ( A bargin is something you don't need , but is a hell of a deal... Lol )

Personally, I think you only live once... enjoy your hobby.... Buy it. And consider adding an adjustable gas block... works wonders IMHO.

Spot on . It is done. I'll post some updates.

Question: Do you dislike cleaning your guns? If the answer is yes, there is no hope for you.

[bfoosh006]

Just received an E-mail from Faxon... 25% off a Nitrated .308 BCG if you buy a clearance .308 barrel..... soooo.... if you are interested, you might phone them and see if you can add it to your order.

[Boot_Scraper]

Saw that too. I gotta pace myself. It shipped already anyways. 

Thanks for looking out though! @bfoosh006

Now I'm onto optics. The giant Nikon I have ain't gonna cut it. I'm normally a vortex kinda guy but I'm eyeing a VX-2 by Leupold. It's a smidge lighter.

Check out Primary Arms optics. You will not be sorry.

This... I have a few 4-14 Illuminated FFP's w/ ACSS... Very nice for the money.

The Illumination knob is stiff... but for a Under $300 Front focal Plane scope... I can live with it.

I just use a faster burning powder.

[Robocop1051]

Most .308 cartridges get complete ignition in 15.5 inches. A long time ago I posted a breakdown of the velocity from about 6" out to 26" in 2" increments. After 16" the increase in velocity drops considerably. The bonus of a 20" vs a 16" is negligible. It's really only worth it to jump to 24" and if you do that then you should be shooting a 6.5c and not a .308. 

The .308 is really only optimal to 600 yards. After that the 6.5c surpasses it in performance. A 16" .308 will perform near as well as a 24" .308 under 600 yards. So there's not a bunch of reasons to have an extra long .308... other than "because I want one"... which really is the best reason to buy anything.

IMHO....IMR 3031... pretty sure it was used in the original FGMM... the red and white boxed stuff.

The M1A guys certainly like it in the 16" M1A Scout... made tack drivers out of numerous Scouts over on M14Forum.com

Would you still have a link to your info?

I'd like to look at it.
