Building my first complete AR15

I’m in the process of building an AR 223 for predator hunting. I will most likely use the Nosler 60 Grain Ballistic Tip Varmint Bullet.

This weapon will spend a lot of time riding in a rack on my ATV as I am disabled and I have limited mobility. This type of hunting is for another thread that I would like to start.

It will have a ThunderBeast Ultra Nine attached most all the time. The Krieger barrel is a heavy weight barrel. I will most likely put a Nightforce or Vortex scope on this weapon.

I’m looking for your throughs and ideas on this build. I'm sure that I have missed a couple of small pieces that I have not listed.

I would rather pay once and cry once.

I also have a chance to buy this weapon instead.

Go to Joe Bobs or Palmeto State Armory and get a complete upper including bolt carrier and bolt, on sale cheap. Minute of Coyote (MOC) doesn't have to be MOA. Although with a little testing of loads you will find a good shooting load. Then buy one of those plastic complete Lowers for $100 and you are coyote ready. Unless you are going to use a suppressor, an adjustable gas block is not necessary. If you are NOT going to target shoot in competition that $500 bucks spent on a Krieger barrel are a waste of money. Just my opinion, but I have killed a bunch of Yotes and Pdogs without the aid of a competition target ready rifle. Don't get me wrong, I have a Black rifle that I compete with in local F-TR at 3/5/6 hundred yards, but I don't take it out in the field and risk dropping it or god forbid the scope. Always build purpose built equipment.

MgySgt, thanks for the input. It has sent me back to the drawing board. I want to build this weapon piece by piece. This is to be a learning experience for me. I'll stick with quality optics. I cannot hit what I cannot see. I will also be using the scope during night hunts with lights. I will be using a suppressor so I'll be keeping the adjustable gas block. I'll look at other barrels also.

Bryan H, I would like to build a nice weapon but MgySgt has a point about "purpose built." This weapon is going to see a lot of the elements and I do fall once in awhile, LOL. I will not be building one using the plastic lowers.
 
Well, here is what I have on order or on-hand. Have about $1050.00 invested. When I get it built I'll post a pic.

Do you already have your Ultra 9 in the works? I was curious what the thought process was to go the 9 over the 7? I would think for this application at least, the shorter package might outweigh the slightly better suppression levels?
 
Well this is what I ended with minus the Thunderbeast as I wait for my paperwork.
Had to have work done on the barrel as the diameter was to large. I had the barrel fluted. I also had to change the Seekin Handguard to a round one as the other would not fit over the gas block.

Weight at this point without magazines is 10# even.
