Palmetto State Armory 14.7″ / Primary Arms 1-6 build.
I put this gun together, as an alternative to my 16″ carbines, using a 14.7″ barreled Palmetto State Armory upper that uses one of their FN made CHF chrome lined barrels with a pinned flash suppressor. I topped it off with a Primary Arms 1-6x SFP ACSS scope. It’s a perfect fit for this gun and it’s intended purpose as a general purpose carbine. Though I don’t have many rounds through it yet, I’ll be running this in practice and some classes this year, and as I get more rounds through it I’ll be doing followups on it. So far I love it.
