7.5 inch barrel
With a 7.5 inch barrel you have to change to a flash kak can it flash hider because it throws to much junk in your face. After I put a kak on it the gun is fantastic!

This thing is tiny!
Added this to a PSA SBA3 MOE EPT PISTOL LOWER BUILD KIT & VORTEX SPARC AR 1X RED DOT SCOPE build kit. I am using a PDA NiB BCG but the phosphate BCG that came looked great. Swapped some other parts and added a few more. Say hello to my little friend. And PSA shipped really fast; 1 week order to deliver. Thank you PSA.
