I am considering buying a XCR in 5.56 with a light 16" barrel, a M16 three slot muzzle brake, a folding / collapsing M4 stock. I am going to be using the rifle as a home defence weapon, a range weapon, once I buy a caliber conversion kit it might also be used as a hunting rifle, I am planning to possibly use it as a patrol weapon once I become a Law Enforcement Officer. What I am wondering is are there any other factory accessories I should consider with this or in place of what I am planning to buy. In the future I plan to add a vertical foregrip and possibly a light or laser system. Any help would be appreciated. If there is something you recommend please include your review.
