Cousin wanted an AR so we put together a list of parts and he came over at lunch. Took a couple hours but it all came together. He chose a pinned mag at this point. Stag 18" heavy fluted varmint barrel in 223 with 2A handguard, side charging BCA upper, Anderson lower, larue 2 stage trigger and magpul moe stock. I was impressed with this $80 trigger.
