Iv been reading here for a month or two, and finally got a real email to sign up

Im not sure what I really want, other than 5.56 for ammo cost reasons and preditors. Maybe a 6.8 to meet hunting regs.
When I 1st got the bug, I was thinking about the remington r-15, and reading on here, decided to build one, and pay over time.

Now its another "You guys SUCK" post, Iv been bitten...

I went and looked at what I could find, and when it was all done, Rainier Arms sold me on a u/l set and a rra lpk.

Now for the questions...

Piston y/n
16" 18" 20" ?
I like the idea of a fast twist for heaver loads

a 300 or 400 yard setup would be sweet, but can it be done with a 16"?


I HAVE to say Rainier arms guys were great!
I wasnt sure about the info being on the right side of the lower, but when I saw the low ser # I was sold!
Now it seams normal to have the info on the right

Piston y/n pistons are neat but, not necessary

16" 18" 20" ? 16" is a good all-around length. When you need an 18 or 20, you'll get one of those too

I like the idea of a fast twist for heaver loads



a 300 or 400 yard setup would be sweet, but can it be done with a 16"? 16" is more than capable of consistant accuracy out to 400yds. A quality barrel is recommended.





I HAVE to say Rainier arms guys were great! Agreed. I heart Rainier Arms

I wasnt sure about the info being on the right side of the lower, but when I saw the low ser # I was sold!

Now it seams normal to have the info on the right As long as it's within specs, a lower is a lower.


Trigger

Barrel  

Sights  



^these are the critical components to accuracy. Don't skimp on these.

I would stick with a DI, and the 16" should be good enough.

being I have to get everything anyway....
a BCG  (ONLY) for $150ish

a Adam Arms piston setup for $250ish seams like a no brainer, being it has all the other small parts in the kit (gas block, hand gaurds, a bolt carrier to get it running. Sure I have to buy a bolt, but still...

if its less than $100 diff, wouldnt I but crazy to not go piston?

what kinda real world groups can be expected with a 16" at say 300 yrs?

I'd guess that accuracy from a rack grade(common parts) AR is about 1.5MOA, which is about 4.5in at 300 yds.



Now upgrading the above mentioned parts will bring you to 1 or -1MOA accuracy. (3in or less at 300yds)

I've done two builds over the last two years and I'm starting on a third.  It is definately addicting  

The first build was a 16" Noveske 1:7 and the second build was an 18" Rainier Ultramatch 1:8.
Both have Timney 4 lb single stage triggers.

The 18"  shoots a bit better than the 16".  Both are capable of MOA or better with good ammo.

Both of mine like the Fiocchi 50 grain VMax or similar ballistic tip ammo.  At 50-55 cents the Fiocchi is pretty reasonable for sub-MOA ammo.

If you're looking for an all-purpose, first rifle, I'd recommend the 16".  Don't skimp on the trigger.

I was actually thinking that same trigger and Rainier barrel

But then I read about there 16" select..
http://www.rainierarms.com/?page=shop/detail&product_id=2267

..But I also dont wanna skimp on a barrel eather.  Im not sure about a 16" barrel eather. I may be more into a 18 or 20" heavy with no flash hider to keep it shorter

ACTUALLY....Im opened to ideas for other calibers as well, and even what I should avoid.
like to build a 6.8 too

OP- I would suggest that you start out with a "simple" 5.56 in 16" DI and then go from there.  If you build a great lower, then you can start building several different uppers that you can interchange.  That being said you can build your self a super accurate very reliable 16" gun.  My fear is that because the piston system is fickle and supposedly less accurate it will not be your favorite gun.  Good luck this wont be your last AR.

OK I dont need that...

and it seams like everyones in agreement that a longer barrel isnt needed. Wont I be loosing long range smackdown quickly with a shorter barrel?
