looking to build another Ar-15, and was wanting input about the parts list and just a general suggestions about the build. The purpose is longer range shooting (200-600 yards) with a 77gr bullet

Kriger barrel 1:7 or 8 twist 24 inches with .223 wylde chamber
Stag lower
Cmmg upper - flattop
LMT bolt
Jewel trigger
RRA LPK
VTAC free float handguard
Bipod Harris or other (recomendations)
Magpul PRS
Scope - ? (recomendations)

Hows it look?

budget not a huge concern becuase i will be building slowly as I have the money

also suggestions on where to buy would be helpful

with the 7 twist try a heavier bullet,i think sierra makes a 90 grain SMK

The 90 only works with a 1-6.5 or faster. The longer the bullet the faster the twist. Weight has some to do with it but it has more to do with the length of the bullet.

For the 70+ weight range I like the 75gr BTHP from Hornady. Not the A-max. Also you need this book.

And this one.

These 2 books will teach you more than you will ever get on the Internet.

is the kriger barrel really worth the money or are there better choices for less

Curious... why the .223 wylde instead of the NATO chamber that would let you shoot the .223 and the higher pressure 5.56 nato rounds?

Sorry if it's a dumb question, i'm new to the AR.

younggun22 · 09-16-2007, 09:11 PM

becuause the .223 wylde chamber has tighter tolerences the the 5.56 nato chamber which equates to better accuracy

darkvibe · 09-16-2007, 10:11 PM

ah. I had no idea. thanks for answering.

Look at NightForce Scopes and LaRue for the mounting, or even Badger for rings and a base. Another option all around is a White Oak assembled upper. You might consider a mono-pod for attachment to the PRS.. there is a nicely covered 1913 rail on the bottom for that specific use.
