I got bored in march/april when everything was locked down and slow at work, so i cashed out a 100hrs of PTO and decided to build an AR10

Seekins Builders Kit... matching upper/lower and rail
Seekins Bolt/BCG
Proof CF .308 1/10 20” Barrel
Area 419 MB and Arca Rail
SLR Adjustable Gas Block
Radian Raptor CH
Geissele Trigger
Ambi Safety
PRS 3 Stock W/ Rifle Buffer Tube
Tubbs Wire Spring and Odin Works Adj Buffer

Put my OG NF 3-15 on it


Finally everything i needed to finish the build came in today, Barrel just showed up last week.

Used a Young Manufacturing ejector removal tool
I took the ejectors out of the bolt, used go and nogo gauges to check the head space.

Used SLR jig to put a second dimple in the barrel for the gas block

Got the gas block tube on and check fitment, all good

Used a Young Manufacturing upper receive block and got that barrel on and barrel nut tightened

Gas block installed on and set screws installed.

Rail installed and Muzzle Brake installed

Assembled and here it is ...

Nice! Update us with a range report.
 
Nice build! Should be an awesome rifle. I’m building a similar one currently. Seekins is a great company.
