Rock River lower w/ 2-stage trigger Bushmaster Patrolman 16" upper Yankee Hill flip-up front and rear sights Magpul CTR stock Magpul MOE handguard w/MVG foregrip Magpul MIAD grip/trigger guard Magpul ASAP sling mount Bushnell MP red dot sight This thing's been a work in progress for almost a year now. Before all you old skool anti-"black gun" types cast the first stone, I'm not going to BS myself and say I can use it for hunting or home defense or whatever... I just wanted a gun that was cool, lightweight and fun to shoot. Initial range report was consistent 4-4.5" groups at 100yds with 5 rounds. I know this sounds unimpressive, but the MP is only capable of 3MOA, so I'm satisfied with that for now. I'm sure it will improve with practice. I'm open to feedback, so fire away!!
