I finally got my first AR built. I am pretty pumped. It turned out very well. I went slow with the build and did most of the fine details I learned on the forum.
My journey started a year ago when I ordered a complete entry upper from AA. I gave up on it in September and decided to build my own with a Lilja 319. The barrel ended up being the last piece. I got it the same day I got the AA upper.
Lower
Oly Arms forged lower. I did my own trigger job with the set screw in the grip screw hole.
Magpul ACS-L stock
Upper
Vltor MUR w/ forward assist.
PF bolt carrier
MF Bolt
Rock Hollow Tactical Carbon Fiber Handguard
Lilja 319, fluted 8T barrel
Vltor VC-301 flash hider
Tweaks
Bolt - I polished the extractor and smoothed the rough edges. I also polished the ejector face and rounded the edge.
I polished the bolt face by super gluing some fine grit sand paper to the bottom of a case. I then held the case against the bolt while I spun the bolt with a drill.
I also trimmed the ejector spring, so the ejector was just above the bolt when not compressed.
Extension - I polished the extension lugs so they wouldn't scratch the brass on its way out.
All of that paid off. The brass looks almost brand new after firing. It also ejects straight out at 3 o'clock and lands in a small pile 6ft away. I could have caught it all in a 5gal bucket.
I tried for one group with Factory SST. I pulled my 5th shot, but before that, I had a .7" group. It shoots very smooth. You can easily watch hits on steel at 100yds.
Paint
I painted the upper, lower, and barrel with KG Gun Kote Mil Spec OD Green. I am really happy with it. I know it isn't the most durable coating, but it is easy to apply.
Weight and Balance
It weighs in a just over 6lbs w/o scope and just under 7.5lbs w/ scope.
It balances right under the serial number on the mag well. I am not sure if that is good or not. It feels nice when shooting off hand. I was able to hit a 5" plate at 100yds while standing.
