Upper assembly
Basic box and bubble rap, they also included a box head Allen key for my optioned adjustable gas block which is perfect for clearing through the handguard. The machining is very nice and the handguard feels rugged. Looks great next to my BCM. Overall Very well executed for the price. Ive only put 16 rounds through it but they were hitting solid out to 350 yards. I still need to build a more refined buffer and spring assembly in order to reach its true potential. Great Value.
