I want to buy a POF-308 but I would like some expert advice on the perfomance differances between a 20 inch Barrel vs. a 16.5 inch Barrel. Do you guys know how much more velocity and energy I would get out of 3.5 more inches with standard 308 ammo?
Also,I am having trouble finding one of these rifles. I have a friend with an FFL but the wait is 5 months from the factory for $2000 or $2,300 from another dealer that has one in stock. Anybody know where one is for sale now for that?
Thanks in advance for any helpful replies.

16.5" is being used in comp to 920 yards.

I forget, but I asked the same question and for the the ranges I planned to shoot, the 16.5 was fine (out to 600 yards) vs. the 20" and was lighter and more manueverable.

Depends on your priorities.

Try calling Rainier Arms to see about buying one or getting on the list for one as soon as they come in.

MSRP is actually $2400. If you know of a dealer with one in stock for $2300, my guess is it will not last. if you check some of the gun auction sites, you will see people paying more for ones that are instock to be shipped immediately.


edit to add:

it is late, long day in a precision rifle class, so excuse me if I have my numbers a little mixed up......but I think it is somewhere between 30 and 50fps per inch increase in velocity for the 308.

Thanks for the replys,but that brings up another question: If it is only 30 or 50 FPS more added per inch of barrel length,going from 16.5 to 20 would only add at most 175 FPS more right? If it's only 175 more FPS,is that worth the extra bulk/length and weight for only 175 FPS? How much less would the bullet drop at say max for me 600 yards if I had that extra 175 FPS to start with? Does it add much more Foot Pounds of Energy at 500 or 600 yards?
Another question is: Since the bullet is in the barrel for more time in the Longer 20 inch barrel than it is in the 16 inch,wouldn't the barrel move off target from recoil more on the longer barrel than the shorter? If so,why do long range target/sniper guys want longer barrels.
With a 308,is there a lot more muzzle flash on a 16 inch compared to a 20 inch barrel,does all the powder burn up in the barrel on a 20 vs 16?
If these are not brilliant questions,Please be nice,I am not an expert,that is why I am asking all of you guys. Thanks,John

the non "brillant" question is the ones you don't ask before you make a purchase....nothing dumb about properly educating yourself before a purchase.

I was shooting a 20" uppers last weekend at a precision rifle class, we did some night shooting......the 20" flash was not that bad at all. I do not have a 16" but there is deffinitely more flash from my 14.5" 308 POF upper.

Don't worry about moving off target because your using a 20" over a 16", never heard or even thought of that.........bullet will be out of the barrel before that ever makes a difference.....shorter barrel means less wheight, which in turn equals more felt recoil.

If I remember correctly the powder is burnt up after about 18 or 19" of barrel.

We have shot 12" 308s out to 925 yards............what are you doing with the rifle? more hunting, or paper shooting? one of the guys at work took a deer at just over 400 yards with his 16" 308.

I have a P-308 with the 14.5" barrel. I went with the shorter barrel because I don't plan on shooting past 300 yards and from what I have read, the accuracy was no different at those distances with the shorter barrel. If you are looking for more technical information regarding POF products and want a dealer that has the rifle in stock, don't hesitate to call Felex at AF Guns/Gunpoint out of Sarasota, FL. His number is: (941) 524-9607. If he doesn't have something in stock, he will get it in a few days, not months. I have purchased a few POF rifles and uppers from him in the past 2 years and he is very knowledgeable and honest. Also, he has all the accessories you could ever want for your rifle from optics, BUIS, etc. Good luck.

I'm guessing that muzzle-flash in 14.5-in long .308 barrel is a function of under-burned propellant gasses exiting the shorter barrel??? I've got zero hands-on, personal experience with either, so this is 100% conjecture. ––CC

yes.....a lot of unburnt powder with the shorter barrel..........I wanted the 14.5" so I can SBR it and use it with my 308 suppressor.

"Ilove2 shoot" asked "............what are you doing with the rifle? more hunting, or paper shooting? one of the guys at work took a deer at just over 400 yards with his 16" 308."
Answer: I just go out plinking in New Mexico where there are mountains and there is no brush or trees so you can see and shoot for miles and miles. I would like to be able to hit a rock the size of a basketball at 600 yards. I wish they made an 18 inch barrel,I think that would be perfect for me,but since they don't,I am just trying to decide if I should go 16 or 20. I just like the idea of getting all of the powder burned up in the barrel before the bullet is out. If we only get 30 to 50 FPS more per inch then that would only add 120 to 200 FPS if I go with the 20 barrel right? Would 200 FPS more velocity make much difference for me if I am trying to shoot a basketball size rock on a hill 600 yards away? What if it were 800 yards away? I know that is really really far,but it never hurts to ask. Thanks in advance for all the helpful replys. John

P.S.-Unfortunately all of this may not matter because now I can't even find a POF-308 for sale that is in stock and if Obama wins in 4 days he will ban this incredible marvel of engineering technology so go vote.
