This was my first full build. I had assembled several lowers and rebuilt 1 dedicated 22 upper prior to this. I traded some surplus 7.62x51 for the 7.5" barrel and began a build from there. It's a mix of new, used, and on sale parts. I used a PSA blem upper, Delaware Machinery blem lower, JP adjustable gas block (modified by adding a set screw to lock the gas port screw), Mas Defense 7.5" 1:7 twist barrel, Primary Weapons System FSC30 compensator, Guntec slim keymod freefloat handguard and pistol buffer for the Sig Brace, nickel boron BCG, basic LPK & upper build kit, & Vortex strikefire.
I had the gas block, upper, and lower receivers cerakoted in titanium but decided to leave the other components alone until I decide if there will be any changes. I've only put 60 rounds through it so far, it's one loud little fire cracker.
